    Full Text Available Documentamos la dieta del jabalí silvestre en el centro-sur de Chile basados en el examen de 20 estómagos colectados en los faldeos de volcán Mocho-Choshuenco (39°54' S, 72°02' O y en el Parque Nacional Vicente Pérez Rosales (41°03' S, 71°54' O. La dieta está representada por animales, vegetales y hongos. Entre los vegetales y hongos son consumidas tanto las partes epígeas como hipógeas, lo mismo que frutos y semillas. Hongos y rizomas de Gunnera tinctoria constituyen ítemes vegetales cuantitativamente importantes en la alimentación. El jabalí forrajea en general en ambiente boscoso, pero las especies vegetales más frecuentes en la dieta se encuentran en espacios abiertos o fuera del bosque. El ambiente dominado por Chusquea spp. constituye un importante sitio de alimentación. Los roedores de la familia Muridae dominan entre los animales determinados en la dieta del jabalí. Esta situación, sin embargo, parece obedecer a la ocurrencia de una ratada producto de la semillación masiva de Chusquea spp. durante la época de muestreo. Las aves de la familia Rhinocryptidae e invertebrados (en especial larvas del coleóptero Chiasognathus grantii constituyen parte frecuente de los ítemes animales de la dieta del jabalí. En comparación a estudios en otras partes del mundo, el jabalí silvestre en Chile consume hongos en porcentaje de ocurrencia similar (65 % a su dieta en Estados Unidos de América pero bastante más alta que su dieta en Europa (5-32 %. En relación al volumen del componente animal, el jabalí en Chile consume más (16,1 % que en Estados Unidos de América (6 % y que en Europa (7-13 %We document the diet of wild boar in south-central Chile based on analysis of 20 stomachs collected on the outskirts of Mocho-Choshuenco volcano (39°54' S, 72°02' W and of Vicente Pérez Rosales National Park (41°03' S, 71°54' W.

    Fifty-seven wild boars (Sus scrofa) from protected regions of Iran were examined for helminths. Sixteen species of helminths were collected; there were ten nematodes, one acanthocephalan, two trematodes and three larval cestodes. New host and distribution records were established for all helminths except of Taenia solium cysticerci. Wild boar shared nine of these helminths with domestic pigs, six with ruminants and three with human beings in Iran. Metastrongylus pudendotectus and M. salmi are reported for the first time from Iran.

    A total of 12 gastrointestinal tracts of wild boars (Sus scrofa) from western Iran (Luristan) were examined for protozoan infection between September 2000 and November 2001. Of 12 boars examined, 67% harbored one or more species of the following protozoa: Balantidium coli (25%), Tritrichomonas suis (25%), Blastocystis sp. (25%), Entamoeba polecki (17%), Entamoeba suis (8%), Iodamoeba butschlii (17%), and Chilomastix mesnili (8%). Four of these protozoan species also are reported in humans, and persons living in rural areas where wild boars are abundant should take precaution to avoid infection.

    Increased density and distribution of wild boar populations are likely to promote interactions and transmission of certain pathogens, not only among wild boar but also from wild boar to livestock or humans and vice versa. The purpose of this study was to determine seroprevalence against seven selected pathogens in wild boar living in four different areas in Greece. In total, 359 serum samples were collected from extensively farmed wild boar (Sus scrofa scrofa) originating from four distinct geographical areas throughout Greece from April 2012 to August 2013. Samples were tested for antibodies to Actinobacillus pleuropneumoniae, African swine fever virus (ASFV), Aujeszky's disease virus (ADV), classical swine fever virus (CSFV), Erysipelothrix rhusiopathiae, Mycoplasma hyopneumoniae and porcine reproductive and respiratory syndrome virus (PRRSV). Prevalence was compared among the four regions using Fisher's exact test. Low overall seropositivities of 2.4% and 5.6% were detected for E. rhusiopathiae and PRRSV, respectively, higher ones for ADV (32.0%) and the highest (72.5% and 90.5%) for M. hyopneumoniae and A. pleuropneumoniae, respectively. All sera tested were found negative for antibodies directed against CSFV and ASFV. This is the first report of exposure of wild boars to selected pig pathogens in Greece. These results are indicative of the circulation of these pathogens in Greece with the exception of CSFV and ASFV and suggestive of the potential role of wild boars on their maintenance and transmission to their domestic counterparts and vice versa.

    Determining whether a species' vocal communication system is graded or discrete requires definition of its vocal repertoire. In this context, research on domestic pig ( Sus scrofa domesticus ) vocalizations, for example, has led to significant advances in our understanding of communicative functions. Despite their close relation to domestic pigs, little is known about wild boar ( Sus scrofa) vocalizations. The few existing studies, conducted in the 1970s, relied on visual inspections of spectrograms to quantify acoustic parameters and lacked statistical analysis. Here, we use objective signal processing techniques and advanced statistical approaches to classify 616 calls recorded from semi-free ranging animals. Based on four spectral and temporal acoustic parameters-quartile Q25, duration, spectral flux, and spectral flatness-extracted from a multivariate analysis, we refine and extend the conclusions drawn from previous work and present a statistically validated classification of the wild boar vocal repertoire into four call types: grunts, grunt-squeals, squeals, and trumpets. While the majority of calls could be sorted into these categories using objective criteria, we also found evidence supporting a graded interpretation of some wild boar vocalizations as acoustically continuous, with the extremes representing discrete call types. The use of objective criteria based on modern techniques and statistics in respect to acoustic continuity advances our understanding of vocal variation. Integrating our findings with recent studies on domestic pig vocal behavior and emotions, we emphasize the importance of grunt-squeals for acoustic approaches to animal welfare and underline the need of further research investigating the role of domestication on animal vocal communication.

    Experienced forensic pathologists and examiners may be familiar with the phenomenon of postmortem iris color change; however, only Knight, Simpson's forensic medicine, Arnold, London, 1997; Ref. 1 and Saukko and Knight, Knight's forensic pathology, 3rd ed., Arnold, London, 2004; Ref. 2 have referred to it in the literature, and to date, there have been no published scientific research studies on this taphonomic artifact. A controlled experiment was conducted of postmortem changes to isolated Sus scrofa eyes. The eyes (n = 137) were separated into three groups and each sample was observed for 3-day postmortem at a different temperature. In addition, a Sus scrofa head was obtained to observe postmortem changes of eyes in situ. All isolated blue eyes in the experiment, at room temperature and higher, changed to brown/black within 48 h. The in situ blue eye, at room temperature, turned brown/black within 72 h. If iris color consistently changes postmortem in humans, then this taphonomic artifact must be incorporated into victim identification protocol, including disaster victim identification software, and autopsy reports to prevent inaccurate victim identification and inappropriate exclusion from the identification process.

    Full Text Available Abstract Background The wild boar (Sus scrofa is among the most widespread mammal species throughout the old world. Presently, studies concerning microsatellites in domestic pigs and wild boars have been carried out in order to investigate domestication, social behavior and general diversity patterns among either populations or breeds. The purpose of the current study is to develop a robust set of microsatellites markers for parentage analyses and individual identification. Findings A set of 14 previously reported microsatellites markers have been optimized and tested in three populations from Hungary, Portugal and Spain, in a total of 167 samples. The results indicate high probabilities of exclusion (0.99999, low probability of identity (2.0E-13 – 2.5E-9 and a parentage assignment of 100%. Conclusions Our results demonstrate that this set of markers is a useful and efficient tool for the individual identification and parentage assignment in wild boars.

    We used serology to estimate the prevalence of exposure to chlamydiae in Italian populations of wild boars (Sus scrofa). Sera from 173 hunter-killed wild boars harvested during the 2006-2009 hunting seasons in three Italian regions were tested for antibodies to Chlamydia suis, Chlamydophila pecorum, Chlamydophila abortus, and Chlamydophila psittaci by the microimmunofluorescence test. Antibody titers to chlamydiae ≥ 1:32 were detected in 110 of the 173 samples tested (63.6%). Specific reactivity could be assessed only in 44 sera with antibody titers to C. suis that were two- to threefold higher than antibody titers against the other chlamydial species; the other 66 sera had similar reactivity against all the chlamydia species tested. Antibody to C. suis was detected in sera from wild boar populations with rare or no known contact with domestic pigs. These results suggest that the wild boar could be a chlamydia reservoir and may acquire chlamydiae independent of contacts with the domestic pig.

    In a forensic context, microbial-mediated cadaver decomposition and nutrient recycling cannot be overlooked. As a result, forensic ecogenomics research has intensified to gain a better understanding of cadaver/soil ecology interactions as a powerful potential tool for forensic practitioners. For this study, domestic pig (Sus scrofa domesticus) (4g) and grass (Agrostis/Festuca spp) cuttings (4g) were buried (July 2013 to July 2014) in sandy clay loam (80 g) triplicates in sealed microcosms (127 ml; 50 × 70 cm) with parallel soil only controls. The effects of the two carbon sources were determined by monitoring key environmental factors and changes in soil bacterial (16S rRNA gene) and fungal (18S rRNA gene) biodiversity. Soil pH changes showed statistically significant differences (p0.05) was observed between the treatments. Copyright © 2015 The Chartered Society of Forensic Sciences.

    The protozoon Neospora caninum is a major cause of abortion in cattle worldwide. Canids (Canis familiaris, Canis latrans, Canis lupus) are definitive hosts whereas many other animal species, including pigs, are intermediate hosts for the parasite. Between 2012 and 2014, serum samples from 1059 feral swine (Sus scrofa) from 29 states of the USA were tested for N. caninum antibodies, using the N. caninum agglutination test (NAT). Of these, 159 (15.0%) feral pigs from 21 states tested positive, with a range of titers of 1:25 (cut-off) (n=153), 1:200 (1), 1:400 (1), 1:800 (3) and 1:3200 (1). Results indicate widespread exposure of feral swine to N. caninum infection across the USA. Published by Elsevier B.V.

Microstructural studies revealed that fiber in exudative pork was the least and averaged 39.7 µm, normal pork was characterized by diameter of muscle of 45.5 µm, while DFD pork ‑ 48.3 µm. Protein composition of Sus scrofa muscle tissues were also investigated by one-dimensional and two-dimensional electrophoresis. 6 protein fractions were identified by mass spectrometry and confirmed as potential biomarkers of pork quality defects in meat and processes meat product. It also has been shown that PSE pork contains 8 characteristic peptides, NOR - 14, DFD - 18. Cathepsin D, calpain 3 and myoglobin content were measured in pork of different categories. The highest content of cathepsin D, calpain 3 and myoglobin was noticed in PSE pork and averaged 82.16 ±3.30 ng.mL-1; 1.280 ±0.082 ng.mL-1; 3.973 ±0.506 ng.mL-1, respectively. Since the study was carried out on samples of meat 24 hours after slaughter, this work had the prospect to further study of meat with different defects of quality during long-term autolysis.

  4. Characterization of Sus scrofa small non-coding RNAs present in both female and male gonads.

    Directory of Open Access Journals (Sweden)

    Dorota Kowalczykiewicz

    Full Text Available Small non-coding RNAs (sncRNAs are indispensable for proper germ cell development, emphasizing the need for greater elucidation of the mechanisms of germline development and regulation of this process by sncRNAs. We used deep sequencing to characterize three families of small non-coding RNAs (piRNAs, miRNAs, and tRFs present in Sus scrofa gonads and focused on the small RNA fraction present in both male and female gonads. Although similar numbers of reads were obtained from both types of gonads, the number of unique RNA sequences in the ovaries was several times lower. Of the sequences detected in the testes, 2.6% of piRNAs, 9% of miRNAs, and 10% of tRFs were also present in the ovaries. Notably, the majority of the shared piRNAs mapped to ribosomal RNAs and were derived from clustered loci. In addition, the most abundant miRNAs present in the ovaries and testes are conserved and are involved in many biological processes such as the regulation of homeobox genes, the control of cell proliferation, and carcinogenesis. Unexpectedly, we detected a novel sncRNA type, the tRFs, which are 30-36-nt RNA fragments derived from tRNA molecules, in gonads. Analysis of S. scrofa piRNAs show that testes specific piRNAs are biased for 5' uracil but both testes and ovaries specific piRNAs are not biased for adenine at the 10th nucleotide position. These observations indicate that adult porcine piRNAs are predominantly produced by a primary processing pathway or other mechanisms and secondary piRNAs generated by ping-pong mechanism are absent.

    Bovine tuberculosis is a chronic disease of cattle ( Bos taurus ) caused by the bacterium Mycobacterium bovis . Efforts have been made in the US to eradicate the disease in cattle, but spillover into wildlife and subsequent spillback have impeded progress in some states. In particular, infection in white-tailed deer ( Odocoileus virginianus ) has been followed by infection in cattle in some Midwestern states. Infection has also been documented in feral swine ( Sus scrofa ) on the Hawaiian island of Molokai and in various European countries, but no large-scale survey of antibody exposure to the bacteria has been conducted in feral swine in the US. We tested 488 sera from feral swine collected near previously documented outbreaks of bovine tuberculosis in cattle and captive cervids, in addition to 2,237 feral swine sera collected across the US from 1 October 2013 to 30 September 2014. While all but one of the samples were antibody negative, the results are important for establishing baseline negative data since feral swine are capable reservoirs and could be implicated in future outbreaks of the disease.

    :  Feral swine ( Sus scrofa) are a pathogen reservoir for pseudorabies virus (PrV). The virus can be fatal to wildlife and contributes to economic losses in the swine industry worldwide. National surveillance efforts in the US use serology to detect PrV-specific antibodies in feral swine populations, but PrV exposure is not a direct indicator of pathogen transmission among conspecifics or to non-suid wildlife species. We measured antibody production and the presence of PrV DNA in four tissue types from feral swine populations of Florida, US. We sampled blood, nasal, oral, and genital swabs from 551 individuals at 39 sites during 2014-16. Of the animals tested for antibody production, 224 of 436 (51%) feral swine were antibody positive while 38 of 549 feral swine (7%) tested for viral shedding were quantitative polymerase chain reaction (qPCR)-positive for PrV. The detection of PrV DNA across all the collected sample types (blood, nasal, oral, and genital [vaginal] swabs) suggested viral shedding via direct (oronasal or venereal), and potentially indirect (through carcass consumption), routes of transmission among infected and susceptible animals. Fourteen of 212 seronegative feral swine were qPCR-positive, indicating 7% false negatives in the serologic assay. Our findings suggest that serology may underestimate the actual infection risk posed by feral swine to other species and that feral swine populations in Florida are capable of shedding the virus through multiple routes.

    Full Text Available Presented in this paper are the correlations between different soil parameters [presence of grubs, earthworms, pH, content of P2O5, K2O and organic matter (OM in soil] and wild boar (Sus scrofa [L.] damage to grasslands. The soil samples and damage assessments were performed at six locations in the Kočevje region, which is a densely wooded part of South East Slovenia. A significant positive correlation was discovered between the extent of damage due to wild boar rooting in grasslands and the number of grubs (r=0.73, the weight of grubs (r=0.69 and the content of P2O5 (r=0.87 in the soil. The quantity and weight of grubs in soil were significantly influenced by soil pH, the content of CaCl2 (r=0.71/0.72, P2O5 (r=0.90/0.91, and OM (r=0.74/0.77; while the quantity and weight of earthworms in soil were influenced by the content of K2O (r=0.81/-0.84. A moderate yet insignificant correlation (r=0.48/0.56 was discovered between the number and weight of earthworms in soil and the extent of grassland damage. Grubs represent a more important source of protein for wild boars than earthworms; consequently, reducing the quantity of grubs in soil could minimise the extent of damage caused by boars.

    Twenty Sus scrofa carcasses were used to study the effect the presence of clothing had on decomposition rate and colonization locations of Diptera species; 10 unclothed control carcasses were compared to 10 clothed experimental carcasses over 58 days. Data collection occurred at regular accumulated degree day intervals; the level of decomposition as Total Body Score (TBSsurf ), pattern of decomposition, and Diptera present was documented. Results indicated a statistically significant difference in the rate of decomposition, (t427  = 2.59, p = 0.010), with unclothed carcasses decomposing faster than clothed carcasses. However, the overall decomposition rates from each carcass group are too similar to separate when applying a 95% CI, which means that, although statistically significant, from a practical forensic point of view they are not sufficiently dissimilar as to warrant the application of different formulae to estimate the postmortem interval. Further results demonstrated clothing provided blow flies with additional colonization locations. © 2015 American Academy of Forensic Sciences.

    Tuberculosis, a chronic progressive disease, has been reported in bovine, swine, and primate species. Here, we report the first case of Mycobacterium tuberculosis infection in a Korean wild boar ( Sus scrofa coreanus). The owners this domesticated boar brought it to the Gyeongbuk Veterinary Service Laboratory in Korea after it was found dead and severely emaciated. Demarcated yellowish white nodules were found around the larynx and retropharyngeal lymph node during necropsy. The lungs had diffuse fibrinous pleuritis, severe congestion, and scattered nodules. More nodules were found in the spleen. Tuberculosis is characterized by massive macrophage infiltration and central caseous necrosis; both characteristics were found in the lungs. Histopathologic examination revealed that the alveolar lumen had marked fibrosis and exudates. Examination of the fluid revealed extensive macrophage permeation. To confirm a Mycobacterium infection, PCR was performed using two primer sets specific to the rpoB gene of Mycobacterium; Mycobacterium was detected in the lungs and spleen. To identify the species of Mycobacterium, immunohistochemical evaluation was performed using antibodies against Mycobacterium tuberculosis and Mycobacterium bovis . The results revealed immunoreactivity against M. tuberculosis but not against M. bovis . The consumption of undercooked or raw meat from game animals may expose humans and other animals to sylvatic infection. Consequently, Koreans who ingest wild boar may be at risk of a tuberculosis infection. To reduce the risk of foodborne infection and maintain public health, continuous monitoring and control strategies are required.

    Full Text Available Thirty pairs of kidneys of wild boar (Sus scrofa were studied from adult males, with permission from the Brazilian Institute of the Environment (Process nº 02001.003237/05, aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal; the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25% between the right and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.

    Full Text Available The objective of this investigation was to estimate the occurrence of infections by the three zoonotic bacteria Anaplasma phagocytophilum (A. phagocytophilum, Borrelia burgdorferi sensu lato (B. burgdorferi s.l. and Coxiella burnetii in wild boars (Sus scrofa in Central Italy. The spleen samples from 100 hunted wild boars were submitted to DNA extraction and PCR assays were carried out to detect the three agents. One (1% animal was positive for A. phagocytophilum, and three (3% for B. burgdorferi s.l. No positive reactions were observed for Coxiella burnetii. Wild boars did not seem to play an important role in the epidemiology of the three investigated agents. However, the detection of A. phagocytophilum and B. burgdorferi s.l. in the spleen of the tested animals showed that wild boars can harbor these pathogens, thus ticked that feeding on infected wild boars are likely to become infected, too, which represents a source of infection for other animals and humans. This is the first detection of A. phagocytophilum in wild boars in Italy.

    Corynebacterium pseudotuberculosis is the etiologic agent of caseous lymphadenitis, a common disease in small ruminant populations throughout the world and responsible for a significant economic impact for producers. To our knowledge, this is the first characterization of C. pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig (Sus scrofa domesticus). In this study, phenotypic and genotypic identification methods allocated the swine isolates in C. pseudotuberculosis biovar ovis. The vast majority of the isolates were able to produce phospholipase D and were susceptible to most of the antimicrobial compounds tested. Macrorestriction patterns obtained by Pulsed Field Gel Electrophoresis (PFGE) grouped the C. pseudotuberculosis in two clusters with a high similarity index, which reveals their clonal relatedness. Furthermore, swine isolates were compared with C. pseudotuberculosis from caprines and PFGE patterns also showed high similarity, suggesting the prevalence of dominant clones and a potential cross-dissemination between these two animal hosts. This work represents the first report of Corynebacterium pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig and alerts for the importance of the establishment of suitable control and sanitary management practices to control the infection and avoid further dissemination of this important pathogen to other animal hosts.

    Full Text Available Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic areas, Nhecolandia and Rio Negro regions. With routine biochemical tests and commercial kits 516 bacteria were identified, with 240 Gram-positive, predominantly staphylococci (36 and enterococci (186 strains. Among Gram-negative (GN bacteria the predominant specimens of Enterobacteriaceae (247 mainly represented by Serratia spp. (105, Escherichia coli (50, and Enterobacter spp. (40 and specimens not identified (7. Antimicrobial susceptibility was tested against 17 drugs by agar diffusion method. Staphylococci were negative to production of enterotoxins and TSST-1, with all strains sensitive towards four drugs and highest resistance toward ampicillin (17%. Enterococci presented the highest sensitivity against vancomycin (98%, ampicillin (94% and tetracycline (90%, and highest resistance pattern toward oxacillin (99%, clindamycin (83%, and cotrimoxazole (54%. In GN the highest resistance was observed with Serratia marcescens against CFL (98%, AMC (66% and AMP (60% and all drugs was most effective against E. coli SUT, TET (100%, AMP, TOB (98%, GEN, CLO (95%, CFO, CIP (93%. The results show a new profile of oxacillin-resistant enterococci from Brazilian feral pigs and suggest a limited residue and spreading of antimicrobials in the environment, possibly because of low anthropogenic impact reflected by the drug susceptibility profile of bacteria isolated.

    The number and spatial distribution of wild boars (Sus scrofa) has increased remarkably in Sweden as well as in other European countries. To understand the population dynamics of the wild boar, knowledge of its reproductive period, oestrus cycle and reproductive success is essential. The aim of this study was therefore to describe the seasonal reproductive pattern and reproductive potential of a wild boar population in Sweden. The study was based on findings from macroscopic examinations of the reproductive organs from 575 hunter-harvested female wild boars (>30 kg body weight). Samples were collected between December 2011 and December 2015 in the southern and middle parts of Sweden. The age of the sampled animals was determined and dressed weight was noted. The stage of the reproductive cycle was defined according to ovarian structures and in relation to the appearance of/and findings in the uterus. The crown-rump length (CRL) of the embryos/foetuses was used to calculate the oestrus/mating month and month for the expected farrowing. The macroscopic examination revealed a seasonal variation of reproductive stages, although cyclic and pregnant females were found in all seasons. Moreover, the estimated oestrus/mating and farrowing months based on the CRL showed that mating and farrowing may occur 'off-season'. The average litter size (no. of embryos or foetuses) per pregnant female was 5.4. Sow weight and age had significant effect on both the reproductive potential (ovulation rate and litter size) and pregnancy rate, respectively. The reproductive potential in the studied wild boar population was high compared to studies from other countries and farrowing may occur 'off-season'. This suggests that the environmental conditions in Sweden, including supplemental feeding, are favourable for wild boar reproduction.

  2. Three-Dimensional Force Measurements During Rapid Palatal Expansion in Sus scrofa

    Full Text Available Rapid palatal expansion is an orthodontic procedure widely used to correct the maxillary arch. However, its outcome is significantly influenced by factors that show a high degree of variability amongst patients. The traditional treatment methodology is based on an intuitive and heuristic treatment approach because the forces applied in the three dimensions are indeterminate. To enable optimal and individualized treatment, it is essential to measure the three-dimensional (3D forces and displacements created by the expander. This paper proposes a method for performing these 3D measurements using a single embedded strain sensor, combining experimental measurements of strain in the palatal expander with 3D finite element analysis (FEA. The method is demonstrated using the maxillary jaw from a freshly euthanized pig (Sus scrofa and a hyrax-design rapid palatal expander (RPE appliance with integrated strain gage. The strain gage measurements are recorded using a computer interface, following which the expansion forces and extent of expansion are estimated by FEA. A total activation of 2.0 mm results in peak total force of about 100 N—almost entirely along the direction of expansion. The results also indicate that more than 85% of the input activation is immediately transferred to the palate and/or teeth. These studies demonstrate a method for assessing and individualizing expansion magnitudes and forces during orthopedic expansion of the maxilla. This provides the basis for further development of smart orthodontic appliances that provide real-time readouts of forces and movements, which will allow personalized, optimal treatment.

    Pigs (Sus scrofa) were introduced to Guam in the 1600's and are now present in high densities throughout the island. Wild pigs are reservoirs for pathogens of concern to domestic animals and humans. Exposure to porcine parvovirus, transmissible gastroenteritis, and Leptospira interrogans has been documented in domestic swine but data from wild pigs are lacking. The close proximity of humans, domestic animals, and wild pigs, combined with the liberal hunting of wild pigs, results in frequent opportunities for pathogen transmission. From February-March 2015, blood, tissue and ectoparasite samples were collected from 47 wild pigs. Serologic testing found exposure to Brucella spp. (2%), Toxoplasma gondii (11%), porcine reproductive and respiratory syndrome (PRRS) virus (13%), porcine circovirus type 2 (36%), pseudorabies virus (64%), Actinobacillus pleuropneumoniae (93%), Lawsonia intracellularis (93%), and porcine parvovirus (94%). Eleven (24%) samples had low titers (1:100) to Leptospira interrogans serovars Bratislava (n=6), Icterohaemorrhagiae (n=6), Pomona (n=2), and Hardjo (n=1). Kidney samples from nine pigs with Leptospira antibodies were negative for Leptospira antigens. Numerous pigs had Metastrongylus lungworms and three had Stephanurus dentatus. Lice (Hematopinus suis) and ticks (Amblyomma breviscutatum) were also detected. No antibodies to Influenza A viruses were detected. In contrast to the previous domestic swine survey, we found evidence of numerous pathogens in wild pigs including new reports of pseudorabies virus, PRRS virus, Brucella, and Leptospira in pigs on Guam. These findings highlight that domestic swine-wild pig interactions should be prevented and precautions are needed when handling wild pigs to minimize the risk of pathogen transmission.

    Full Text Available Background: Wild boars, Sus scrofa, of wide distribution considered as a potential source of zoonotic parasites. The current study aimed to assess the prevalence of helminth infections in wild boars in the Persian Gulf coastal area (Bushehr Province, Southwestern Iran.Methods: Twenty-five wild boars, including 11 males and 14 females, were collected during a course of vertebrate pest control in the Bushehr Province, southwestern Iran in 2013. The specimen were immediately dissected and carefully searched for the parasites. During necropsy, each organ was examined macroscopically for presence of any helminthic agents. Tissue samples were taken from each organ. Moreover, samples were taken from the content of digestive system. Blood samples were also collected from each boar. All the samples were evaluated for helminth infections by parasitological methods.Results: Twenty-two (88% of the wild boars were infected with at least one helminth. Out of 25 wild boars, 1 (4% were infected with Cysticercus tenuicollis, the larval stage of Taenia hydatigena, 13 (52% with Macracanthorhynchus hirudinaceus, 17 (68% with Metastrongylus spp, and 20 (80% with Ascarops spp. Hydatid cyst was detected in the lung of one of the wild boars. No Trichinella spp. larvae were detected in any of the tissues of the animals when evaluated by artificial digestion method. In addition, no contamination with microfilaria was detected in any of animals when the blood samples were tested with Knott’s method.Conclusion: Wild boars are contaminated by some helminthes including zoonotic ones. These animals could be involved in the epidemiology of zoonotic helminth by acting as reservoir hosts. This in turn may bring potential risk for locals and residents of the Bushehr Province, Southwestern Iran.

    Full Text Available Introduction: The literature is not clear in the ultra-structural manifestations of the vocal wrinkles after neural wound. Objective: To verify the alterations that occur in a vocal fold mechanically denervated. Method: In this prospective study, it were utilized 15 hogs of commercial race (Sus scrofa domesticates, with age of 4 to 12 weeks. The animals were distributed in three groups, chosen at random. Everybody was submitted to the denervation of the right vocal fold, with surgical removal of a segment with three centimeters of the recurring right laryngeal nerve. After 45, 90 and 180 days of the operations, it was proceeded the biopsy of the vocal muscles, it was prosecuted the samples for transmission electron microscopy and, for the ultra-structural study, utilized the transmission electron microscopy Philips, model EM208S. Results: The biopsied groups with 45 and 90 days after operation of mechanical denervation, presented disorganization miofibrilar, only vestigial lines Z in many samples, as well like altered mithochondrions presenting limited sizes, and matrix mithocondrial rarefied with rare mithocondrial cristae present. The biopsied group with 180 days after operation of denervation, presented regular sarcomeres, mithocondrions with sizes and regular number with correct positioning between the sarcomerical units. Conclusion: The finds in the ultra-structure of the vocal muscles suggest to re enervation of the muscle being that the muscular mithochondrions were the most sensible structures to the denervated condition, successions by the cytoarchiteture of the miofibrilas; the finds in the ultra-structure of the vocal muscles suggests to reinervation of the muscle in the period of approximately six months.

    Biting flies have been suggested as mechanical vectors of vesicular stomatitis New Jersey Virus (family Rhabdoviridae, genus Vesiculovirus, VSNJV) in livestock populations during epidemic outbreaks in the western United States. We conducted a proof-of-concept study to determine whether biting flies could mechanically transmit VSNJV to livestock by using a black fly, Simulium vittatum Zetterstedt (Diptera: Simuliidae), domestic swine, Sus scrofa L., model. Black flies mechanically transmitted VSNJV to a naive host after interrupted feeding on a vesicular lesion on a previously infected host. Transmission resulted in clinical disease in the naïve host. This is the first demonstration of mechanical transmission of VSNJV to livestock by insects.

    Full Text Available Heavy metals are toxic elements naturally present in the environment which can be bioconcentrated by plants and animals and incorporated into food cycles. Thus the use of wildlife species as monitors is a useful tool to assess environmental pollution. Because of its ethological characteristics, wild boar is highly probable to be exposed to pollution, mainly by heavy metals. These pollutants, when present at high enough concentrations, can induce histological lesion in various tissues. The purpose of the present work was to investigate the levels of five metals (cadmium, copper, iron, lead and zinc in wild boar, Sus scrofa, originating from an Apennine area of Emilia Romagna, Northern Italy, and to evaluate any possible correlation with histological lesions eventually observed. Samples of several organs (liver, heart, kidney, diaphragm, abductor muscle, masseter, eye, testis, brain, lung and spleen were collected from hunted animals during winter 2001. Levels of metals were determined on freeze dried tissues employing microwave wet digestion. Toxicological analysis were performed by atomic absorption spectrophotometry and data expressed on a dry weight basis. Histopatological analyses were performed on fixed samples of the same tissue. Highest mean values were found in kidney for cadmium and copper (7 ± 1 ppm and 30 ± 2.6 ppm respectively and in liver for copper (21.16 ± 3.28 ppm, lead (2139 ± 680.6 ppb, iron (415.92 ± 24.41 ppm and zinc (94.76 ± 6.11 ppm. In all other tissues, mean concentrations of each metal were at low levels, and were comparable one another. A statistical difference was found for iron (p<0.05, copper (p<0.05 and cadmium (p<0.01 in kidney, in testis (p<0.01 for zinc and in liver for copper (p<0.05 and cadmium (p<0.01 as function of age cohorts. When sex was considered, a statistical difference was found for iron in eye, for copper in heart and for cadmium in heart and kidney. Histopatological analysis allowed

    Serum samples were collected from wild boars (Sus scrofa) harvested during the 2005-2006 hunting season in Campania, southern Italy. Samples were tested for antibodies to Leptospira interrogan, Brucella spp., Salmonella spp., Aujeszky disease virus (ADV), porcine reproductive and respiratory stress syndrome virus (PRRSV), porcine parvovirus (PPV), classical swine fever virus (CSFV), and swine vesicular disease virus (SVDV). Of the 342 serum samples tested, 15 (4.4%) were seropositive to Brucella spp., nine (2.6%) were seropositive to L. interrogans, 66 (19.3%) were seropositive for Salmonella spp., 105 (30.7%) were seropositive for ADV, 27 (7.9%) were seropositive for PPV, and 129 (37.7%) were seropositive for PRRSV. All sera tested seronegative for SVDV and CSFV antibodies. These results, recorded for the first time in Campania, support the hypothesis that wild boar are reservoirs of certain infectious agents, but some infections in wild boars originate from their domestic counterparts.

    Samples were collected from 203 wild boars (Sus scrofa) hunted in Baden-Wurtemburg, Germany from November-January 2008 and 2009. Samples from the lung and tonsil were analyzed by quantitative polymerase chain reaction (qPCR) for porcine reproductive and respiratory syndrome virus (PRRSV) type 1 (European type) and type 2 (American type). A qPCR to detect porcine circovirus type 2 (PCV2)-specific genome was performed on tissue homogenates including lung, tonsils, and inguinal lymph nodes. Serum samples were tested for antibodies against PRRSV and PCV2 by enzyme-linked immunosorbent assay (ELISA). No PRRSV was detected in any of the 203 samples and one sample had detectable antibodies against PRRSV. We detected PCV2 in organ materials from 103 wild boars with a prevalence of 50.7%. The number of wild boars positive for PCV2 by PCR varied according to the population density of wild boars among woodlands. More positive samples were detected in woodlands with a high density of wild boars. We found no correlation between the number of PCV2-positive wild boars and the density of domestic pigs in the surrounding area. The number of wild boars positive for antibodies against PCV2 by the INGEZIM Circovirus IgG/IgM test kit was low (53 sera positive for IgG- and three sera positive for IgM-antibodies) in comparison to the higher positive results from the INGEZIM CIRCO IgG test kit (102 positive and 12 inconclusive results).

    Glutathione S-transferases (GSTs) play a key role in detoxification of xenobiotics in organisms. However, their other functions, especially response to the natural toxin cantharidin produced by beetles in the Meloidae and Oedemeridae families, are less known. We obtained GST cDNAs from three sources: Cydia pomonella (CpGSTd1), Sus scrofa (SsGSTα1), and Triticum aestivum (TaGSTf3). The predicted molecular mass is 24.19, 25.28 and 24.49 kDa, respectively. These proteins contain typical N-terminal and C-terminal domains. Recombinant GSTs were heterologously expressed in Escherichia coli as soluble fusion proteins. Their optimal activities are exhibited at pH 7.0-7.5 at 30 °C. Activity of CpGSTd1 is strongly inhibited by cantharidin and cantharidic acid, but is only slightly suppressed by the demethylated analog of cantharidin and cantharidic acid. Enzymatic assays revealed that cantharidin has no effect on SsGSTα1 activity, while it significantly stimulates TaGSTf3 activity, with an EC50 value of 0.3852 mM. Activities of these proteins are potently inhibited by the known GST competitive inhibitor: S-hexylglutathione (GTX). Our results suggest that these GSTs from different sources share similar structural and biochemical characteristics. Our results also suggest that CpGSTd1 might act as a binding protein with cantharidin and its analogs. Copyright © 2014 Elsevier Inc. All rights reserved.

    The information conveyed in acoustic signals is a central topic in mammal vocal communication research. Body size is one form of information that can be encoded in calls. Acoustic allometry aims to identify the specific acoustic correlates of body size within the vocalizations of a given species, and formants are often a useful acoustic cue in this context. We conducted a longitudinal investigation of acoustic allometry in domestic piglets (Sus scrofa domesticus), asking whether formants of grunt vocalizations provide information concerning the caller's body size over time. On four occasions, we recorded grunts from 20 kunekune piglets, measured their vocal tract length by means of radiographs (X-rays) and weighed them. Controlling for effects of age and sex, we found that body weight strongly predicts vocal tract length, which in turn determines formant frequencies. We conclude that grunt formant frequencies could allow domestic pigs to assess a signaler's body size as it grows. Further research using playback experiments is needed to determine the perceptual role of formants in domestic pig communication. © 2016. Published by The Company of Biologists Ltd.

    Sarcoptic mange occurs in free-ranging wild boar (Sus scrofa) but has been poorly described in this species. We evaluated the performance of a commercial indirect enzyme-linked immunosorbent assay (ELISA) for serodiagnosis of sarcoptic mange in domestic swine when applied to wild boar sera. We tested 96 sera from wild boar in populations without mange history ("truly noninfected") collected in Switzerland between December 2012 and February 2014, and 141 sera from free-ranging wild boar presenting mange-like lesions, including 50 live animals captured and sampled multiple times in France between May and August 2006 and three cases submitted to necropsy in Switzerland between April 2010 and February 2014. Mite infestation was confirmed by skin scraping in 20 of them ("truly infected"). We defined sensitivity of the test as the proportion of truly infected that were found ELISA-positive, and specificity as the proportion of truly noninfected that were found negative. Sensitivity and specificity were 75% and 80%, respectively. Success of antibody detection increased with the chronicity of lesions, and seroconversion was documented in 19 of 27 wild boar sampled multiple times that were initially negative or doubtful. In conclusion, the evaluated ELISA has been successfully applied to wild boar sera. It appears to be unreliable for early detection in individual animals but may represent a useful tool for population surveys.

    To investigate pseudorabies-virus (PrV) -antibody and viral-DNA prevalence, we collected blood, nasal and genital swabs, and tonsillar and lymph-node tissue samples from 139 wild boars (Sus scrofa; 39 piglets, 30 juveniles, and 70 adults), during the hunting season of 2010-2011 in Tuscany, Central Italy. We performed immunohistochemistry with anti-PrV monoclonal antibodies on selected tissue samples. Forty-three of 139 (30.9%) boars were PrV-antibody positive and a 1,954-base-pair PrV-specific product was amplified from nine nasal (6.5%) and 26 genital (18.7%) swabs. Sequence analysis of PrV-positive PCR products revealed identity scores of 99-100% with Suid herpesvirus 1 strain Becker (JF797219) and confirmed the identification of PrV DNA in tested swabs. There was significantly higher antibody prevalence in adults than in juveniles and in piglets than in juveniles. The prevalence of viral DNA was significantly higher in genital swabs than in nasal specimens. The percentage of positive nasal swabs did not differ among age classes. Piglets had a higher percentage of PCR-positive genital swabs than juvenile and adult subjects (30.8% vs. 13.3% and 14.3%, respectively). Results confirmed that PrV infection is widespread in the wild boar population in the study area. The presence of anti-PrV antibodies and of the PrV virus in piglets could be related to vertical transmission of the virus. This hypothesis was also supported by a higher presence of viral genome in genital swabs than in nasal swabs. This field study supports the importance of vertical transmission of PrV, and the high prevalence of virus in genital swabs supports venereal transmission in adult feral boars.

    Mercury (Hg) is likely bound to large biomolecules (e.g. proteins) in living organisms, and in order to assess Hg metabolic pathways and possible toxicological effects, it is essential to study these Hg containing biomolecules. However, the exact nature of most metal binding biomolecules is unknown. Such studies are still in their infancy and information on this topic is scarce because the analysis is challenging, mainly due to their lability upon digestion or extraction from the tissue. New analytical methods that allow complex Hg-biomolecules to be analysed intact are needed and only few very recent studies deal with this approach. Therefore, as an initial step towards the characterization of Hg containing biomolecules, an analytical procedure has been optimised using size-exclusion chromatography (SEC) with inductively coupled plasma mass spectrometry (ICP-MS) detection. We applied this technique to elucidate the distribution and elution profile of Hg and Se, and some physiological important elements such as Fe, Ni, Zn and Cu, to assess metal binding profiles in liver and kidney samples of red deer (Cervus elaphus) and wild boar (Sus scrofa) who roam freely within the largest Hg mining district on Earth, Almadén in Spain. Elemental fractionation profiles of the extracts from different tissues were obtained using two different SEC columns (BioSep-SEC-S2000 GL 300-1kDa and Superdex 75 10/300 GL 70-3kDa). Similar profiles of Hg were observed in red deer and wild boar; however, significant differences were evident for liver and kidney. Moreover, the profiles of Se showed a single peak at high-medium molecular weight in all investigated tissues, while co-elution of Hg with Fe, Ni, Zn and Cu was observed.

  2. Diagnosis of tuberculosis in the wild boar (Sus scrofa: a comparison of methods applicable to hunter-harvested animals.

    Directory of Open Access Journals (Sweden)

    Nuno Santos

    Full Text Available BACKGROUND: To obtain robust epidemiological information regarding tuberculosis (TB in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar. METHODOLOGY/PRINCIPAL FINDINGS: Six different diagnostic methods for TB were evaluated in parallel in 167 hunter-harvested wild boar. Compared to bacteriological culture, estimates of sensitivity of histopathology was 77.8%, gross pathology 72.2%, PCR for the MPB70 gene 66.7%, detection of acid-fast bacilli (AFB in tissue contact smears 55.6% and in histopathology slides 16.7% (estimated specificity was 96.7%, 100%, 100%, 94.4% and 100%, respectively. Combining gross pathology with stained smears in parallel increased estimated sensitivity to 94.4% (94.4% specificity. Four probable bacteriological culture false-negative animals were identified by Discriminant Function Analysis. Recalculating the parameters considering these animals as infected generated estimated values for sensitivity of bacteriology and histopathology of 81.8%, gross pathology 72.7%, PCR for the MPB70 gene 63.6%, detection of AFB in tissue contact smears 54.5% and in histopathology slides 13.6% (estimated specificity was 100% for gross pathology, PCR, bacteriology and detection of AFB in histopathology slides, 96.7% for histopathology and 94.4% for stained smears. CONCLUSIONS/SIGNIFICANCE: These results show that surveys for TB in wild boar based exclusively on gross pathology considerably underestimate prevalence, while combination of tests in parallel much improves sensitivity and negative predictive values. This finding should thus be considered when planning future surveys and game meat inspection schemes. Although bacteriological culture is the reference test for TB diagnosis, it can generate false

    Fasciolosis is an emerging or reemerging human and animal disease in numerous parts of the world. In Galicia (NW, Spain), the wild boar (Sus scrofa) is the main wild ungulate in terms of abundance and distribution. Its population has continuously increased over the past decades and this population growth has been accompanied by a reduction of habitats, so that the wild boar populations encroach more and more frequently onto agricultural lands. The increase of the interface area between livestock and the wild boars frequently involves the sharing of pastures and water sources, so that the circulation of common pathogens is propitiated. This is the first report concerning the importance of the wild boar as a possible reservoir of Fasciola hepatica infection in Spain. Livers from 358 hunted wild boars were analyzed showing that 11.2% were parasitized by F. hepatica, with burdens ranging from 1 to 14 flukes (mean=2.3). Fecal analysis demonstrated that 40.0% of parasitized animals shed F. hepatica eggs with a mean excretion of 6.1 eggs per gram of feces (epg). The presence of coproantigens analyzed by MM3-COPRO ELISA was positive in 62.9% of infected wild boars. After incubation, the percentage of hatched eggs ranged between 41.0% and 90.0% suggesting that the wild boar is very likely to contribute to the environmental contamination with viable parasite eggs. Comparative morphometric data were obtained using a computer image analysis system (CIAS) on the basis of standardized measurements. F. hepatica from cattle, sheep and wild boars from the same geographical area presents a similar body development and gravidity. Our study shows for the first time that the F. hepatica uterus from the wild boar presents an intermediate size between that found in primary reservoir hosts such as cattle and sheep, i.e., the individual potential egg output capacity of the wild boar does not greatly differ from that detected in Galician livestock. These results show that F. hepatica in

    Full Text Available Wild boar is a host of a number of arthropod-vectored diseases and its numbers are on the rise in mainland Europe. The species potentially impacts ecosystems, humans and farming practices and so its distribution is of interest to policy makers in a number of fields beyond that of the primarily epidemiological goal of this study. Three statistical model outputs describing the distribution and abundance of the species Sus scrofa (Wild boar are included in this data package. The extent of this dataset covers continental Europe. These data were presented as a poster [1] at the conference Genes, Ecosystems and Risk of Infection (GERI 2015. The first of the three models provide a European map presenting the probability of presence of Sus scrofa, which can be used to describe the likely geographical distribution of the species. The second and third models provide indices to help describe the likely abundance across the continent. The two indices include “the proportion of suitable habitat where presence is estimated” and a simple classification of boar abundance across Europe using quantiles of existing abundance data and proxies.

    Full Text Available Abstract Wild boar (Sus scrofa spreading and crop damage in an area of western Prealps We analysed the agricultural damage reports from 1986 to 1996 to evidence the wild boar distribution in Biella province and the pattern of land occupancy. These reports were yearly divided and mapped for the single municipalities to obtain a picture of the range variations in the time. From the same reports we calculated three indexes of the importance of the Wild boar damages: the damaged surface for each municipality, its percentage value on the surface of each municipality and the occurrence of damages for each municipality. During the study period, we observed a dramatic increase of the number of municipalities affected by wild boar damages and of the species range. The yearly damaged surface grew over 25 times too. The Discriminant Function Analysis carried out between damaged and undamaged municipalities correctly classified 78,1% of total cases by three variables: mixed woods, pastures and dry crops, the second one being the most important. The Multiple Regression Analysis of the damages occurrence vs. habitat variables explained 77,3% of independent variable variance by five variables, which entered the model. The trend analysis, carried out by the seasonal regression, using the surface and the occurrence of damages, evidenced a marked seasonality of the damages and a stability trend, after an initial positive trend. Riassunto Per evidenziare la distribuzione del Cinghiale in provincia di Biella e le modalità d'occupazione del territorio nel corso degli anni, sono state utilizzate le denunce dei danni pervenute all Amministrazione provinciale dal 1986 al 1996. Queste sono state ripartite per comune e mappate anno per anno per fornire una rappresentazione delle variazioni di areale nel corso del tempo. Dalle stesse denunce di danni e per lo stesso arco di tempo sono stati calcolati tre indici

    Full Text Available Mycobacterium celatum, a slowly growing potentially pathogenic mycobacterium first described in humans, is regarded as an uncommon cause of human infection, though capable of inducing invasive disease in immunocompromised hosts. According to some reports, a serious disease due to M. celatum may also occur in individuals with no apparent immunodeficiency. In animals, an M. celatum-related disease has been described in three cases only: twice in a domestic ferret (Mustela putorius furo and once in a white-tailed trogon (Trogon viridis. In this paper, we report the first detection of M. celatum in a domestic pig (Sus scrofa domestica and roe deer (Capreolus capreolus. A nation-wide overview of human M. celatum infections recorded in Slovenia between 2000 and 2010 is also given. Pulmonary disease due to M. celatum was recognized in one patient with a history of a preexisting lung disease.

A total of 32 haplotypes were found by screening 211 individuals from eight wild boar populations across Europe and five...... domestic pig populations. European wild boar were characterized by significantly higher levels of haplotype diversity compared to European domestic pigs (HD = 0.904 ± 0.011 and HD = 0.491 ± 0.077 respectively).

    Tularemia outbreaks in humans have recently been reported in many European countries, but data on the occurrence in the animal population are scarce. In North America, seroconversion of omnivores and carnivores was used as indicator for the presence of tularemia, for the European fauna, however, data are barely available. Therefore, the suitability of wild boars (Sus scrofa) and red foxes (Vulpes vulpes) as indicators for the circulation of F. tularensis in Germany was evaluated. Serum samples from 566 wild boars and 457 red foxes were collected between 1995 and 2012 in three federal states in Central Germany (Hesse, Saxony-Anhalt, and Thuringia). The overall rate of seropositive animals was 1.1% in wild boars and 7.4% in red foxes. In conclusion, serological examination of red foxes is recommended, because they can be reliably used as indicator animals for the presence of F. tularensis in the environment.

    A genetic method to identify the breed of origin could serve as a useful tool for inspecting the authenticity of the increasing number of monobreed foodstuffs, such as those derived from small local European pig breeds. Mitochondrial DNA (mtDNA) is practically the only reliable genomic target for PCR in processed products, and its haploid nature and strict maternal inheritance greatly facilitate genetic analysis. As a result of strategies that sought to improve the production traits of European pigs, most industrial breeds presently show a high frequency of Asian alleles, while the absence or low frequency of such Asian alleles has been observed in small rustic breeds from which highly prized dry-cured and other traditional products are derived. Therefore, the detection of Asian ancestry would indicate nonconformity in Protected Denomination of Origin products. This study presents a single base extension assay based on 15 diagnostic mtDNA single nucleotide polymorphisms to discriminate between Asian and European Sus scrofa lineages. The test was robust, sensitive and accurate in a wide range of processed foodstuffs and allowed accurate detection of pig genetic material and identification of maternal ancestry. A market survey suggested that nonconformity of products derived from Portuguese breeds is an unusual event at present, but regular surveys both in the local populations and in commercial products would be advisible. Taking into consideration the limitations presented by other methodologies, this mtDNA-based test probably attains the highest resolution for the direct genetic test for population of origin in Sus scrofa food products.

    The objective of this study was to identify loci associated with tail biting or being a victim of tail biting in Norwegian crossbred pigs using a genome-wide association study with PLINK case-control analysis. DNA was extracted from hair or blood samples collected from 98 trios of crossbred pigs located across Norway. Each trio came from the same pen and consisted of one pig observed to initiate tail biting, one pig which was the victim of tail biting and a control pig which was not involved in either behaviour. DNA was genotyped using the Illumina PorcineSNP60 BeadChip whole-genome single-nucleotide polymorphism (SNP) assay. After quality assurance filtering, 53,952 SNPs remained comprising 74 animals (37 pairs) for the tail biter versus control comparison and 53,419 SNPs remained comprising 80 animals (40 pairs) for the victim of tail biting versus control comparison. An association with being a tail biter was observed on Sus scrofa chromosome 16 (SSC16; p = 1.6 × 10(-5)) and an unassigned chromosome (p = 3.9 × 10(-5)). An association with being the victim of tail biting was observed on Sus scrofa chromosomes 1 (SSC1; p = 4.7 × 10(-5)), 9 (SSC9; p = 3.9 × 10(-5)), 18 (SSC18; p = 7 × 10(-5) for 9,602,511 bp, p = 3.4 × 10(-5) for 9,653,881 bp and p = 5.3 × 10(-5) for 29,577,783 bp) and an unassigned chromosome (p = 6.1 × 10(-5)). An r(2) = 0.96 and a D' = 1 between the two SNPs at 9 Mb on SSC18 indicated extremely high linkage disequilibrium, suggesting that these two markers represent a single locus. These results provide evidence of a moderate genetic association between the propensity to participate in tail-biting behaviour and the likelihood of becoming a victim of this behaviour.

    Trypsin is one of the most important enzymatic tools in proteomics and biopharmaceutical studies. Here, we describe the complete recombinant expression and purification from a trypsinogen expression vector construct. The Sus scrofa cationic trypsin gene with a propeptide sequence was optimized according to Escherichia coli codon-usage bias and chemically synthesized. The gene was inserted into pET-11c plasmid to yield an expression vector. Using high-density E. coli fed-batch fermentation, trypsinogen was expressed in inclusion bodies at 1.47 g/L. The inclusion body was refolded with a high yield of 36%. The purified trypsinogen was then activated to produce trypsin. To address stability problems, the trypsin thus produced was acetylated. The final product was generated upon gel filtration. The final yield of acetylated trypsin was 182 mg/L from a 5-L fermenter. Our acetylated trypsin product demonstrated higher BAEE activity (30,100 BAEE unit/mg) than a commercial product (9500 BAEE unit/mg, Promega). It also demonstrated resistance to autolysis. This is the first report of production of acetylated recombinant trypsin that is stable and suitable for scale-up. Copyright © 2015 Elsevier Inc. All rights reserved.

    Bovine tuberculosis (bTB) is a (re-)emerging disease in European countries, including Switzerland. This study assesses the seroprevalence of infection with Mycobacterium bovis and closely related agents in wild boar (Sus scrofa) in Switzerland, because wild boar are potential maintenance hosts of these pathogens. The study employs harmonised laboratory methods to facilitate comparison with the situation in other countries. Eighteen out of 743 blood samples tested seropositive (2.4%, CI: 1.5-3.9%) by ELISA, and the results for 61 animals previously assessed using culture and PCR indicated that this serological test was not 100% specific for M. bovis, cross-reacting with M. microti. Nevertheless, serology appears to be an appropriate test methodology in the harmonisation of wild boar testing throughout Europe. In accordance with previous findings, the low seroprevalence found in wild boar suggests wildlife is an unlikely source of the M. bovis infections recently detected in cattle in Switzerland. This finding contrasts with the epidemiological situation pertaining in southern Spain. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The origins, ramifications and distributions of the left and right facial arteries were studied in 30 stillborn pigs (Sus scrofa domesticus of the Sadia lineage, 17 males and 13 females, with the aim of increasing morphological knowledge of these structures in terms of their localization and distribution. The species was chosen for its well known commercial importance. The specimen had its artery system filled with stained solution of neoprene latex 601 A and afterwards fixed in an aqueous solution of formaldehyde at 10%. It was observed that in 100% of the studied animals the facial arteries originated from the ventrolateral surface of the external carotid artery, rostrally to the lingual artery. The gland branches divided, supplying the mandibular, parotid, monostomática portion of the sublingual and part of the cervical thymus in muscular branches, irrigating the medial pterygoid, masseter, ventral aspect of the digastrics and cutaneous of the face muscles. Furthermore, the pharyngal branch irrigated the soft palate, tympanic bula and basihyoid, and the submentalis artery was directed towards the submental and the dorsal face of the digastrics muscles.

    The aim of this study was to evaluate the level of lead (Pb) in the livers and kidneys of free-living animals from Poland, with regard to the differences in tissue Pb content between the species. The research material consisted of liver and kidney samples collected from roe deer (Capreolus capreolus), red deer (Cervus elaphus), and wild boar (Sus scrofa) that had been hunted in 16 voivodeships of Poland. The concentration of lead had been measured using inductively coupled plasma optical emission spectrometry (ICP-OES) method. The results show that differences in lead concentration in the organs depended on the geographic location. In roe deer and red deer, the highest mean lead concentrations in the livers and kidneys, observed in the central region of Poland, were twice as high as the lowest concentration of Pb in these animals from the northeastern region of the country. In wild boar, the highest mean concentration of Pb was noted in the livers of animals from the central region of Poland and in the kidneys of animals from the northwestern region, while the lowest lead concentrations in both organs were typical for wild boar from the southeast part of the country. Our results show that areas located in the center and in the north of Poland carry most of the burden of lead bioaccumulation.

    Full Text Available Abstract Background Lymphocyte function-associated antigen-1 (LFA-1, CD11a/CD18, alphaLbeta2, the most abundant and widely expressed beta2-integrin, is required for many cellular adhesive interactions during the immune response. Many studies have shown that LFA-1 is centrally involved in the pathogenesis of several diseases caused by Repeats-in-toxin (RTX -producing bacteria. Results The porcine-LFA-1 CD11a (alpha subunit coding sequence was cloned, sequenced and compared with the available mammalian homologues in this study. Despite some focal differences, it shares all the main characteristics of these latter. Interestingly, as in sheep and humans, an allelic variant with a triplet insertion resulting in an additional Gln-744 was consistently identified, which suggests an allelic polymorphism that might be biologically relevant. Conclusion Together with the pig CD18-encoding cDNA, which has been available for a long time, the sequence data provided here will allow the successful expression of porcine CD11a, thus giving the first opportunity to express the Sus scrofa beta2-integrin LFA-1 in vitro as a tool to examine the specificities of inflammation in the porcine species.

    Full Text Available Parasitic infections are a threat to the wildlife by endangering the health of wild animals and serving as a source of transmission of infectious agents to livestock and humans. Despite the distribution of wild boars (Sus scrofa, wild goat (Capra aegagrus and red deer (Cervus elaphus throughout the world, information on their parasitic infections is limited. Knowledge of the parasitic fauna of animals in protected areas may be used in protection of endangered species. The present study aimed to investigate the status of gastrointestinal parasitic infections in wild boar, wild goat and red deer in the Aynaloo protected area, Northwest of Kaleybar city, East Azerbaijan province. For this purpose, in spring 2015, 30 fecal samples of wild boar, 30 fecal samples of wild goat and 30 fecal samples of red deer were collected. The samples were processed using direct smear and Clayton lane floatation technique. Five species of helminths were detected from wild boar fecal samples consisting of Trichuris suis, Strongyloides suis, Physocephalus sexalatus, Ascaris suum and Metastrongylus apri. Among them,  one species (Strongyloides suis was reported for the first time in Iran. Protozoa were not detected in the fecal samples of the wild boar. Wild goats were infected with Oesophagostomum columbianum, Muellerius capillaris and Eimeria spp. Respiratory larva and Eimeria spp. were detected from red deer samples.

    In this report we describe for the first time the detection of Sarcoptes scabiei type suis mites on domestic pigs in Israel and examine its genetic variation compared with S. sabiei from other hosts. Microscopic examination of skin samples from S. scabiei-infested pigs (Sus scrofa domesticus) revealed all developmental stages of S. scabiei. To detect genetic differences between S. scabiei from different hosts, samples obtained from pig, rabbits (Orictolagus cuniculus), fox (Vulpes vulpes), jackal (Canis aureus) and hedgehog (Erinaceus concolor) were compared with GenBank-annotated sequences of three genetic markers. Segments from the following genes were examined: cytochrome C oxidase subunit 1 (COX1), glutathione-S-transferase 1 (GST1), and voltage-sensitive sodium channel (VSSC). COX1 analysis did not show correlation between host preference and genetic identity. However, GST1 and VSSC had a higher percentage of identical sites within S. scabiei type suis sequences, compared with samples from other hosts. Taking into account the limited numbers of GST1 and VSSC sequences available for comparison, this high similarity between sequences of geographically-distant, but host-related populations, may suggest that different host preference is at least partially correlated with genetic differences. This finding may help in future studies of the factors that drive host preferences in this parasite.

    Full Text Available Aquatic and semiaquatic mammals have the capacity of breath hold (apnea diving. Northern elephant seals (Mirounga angustirostris have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min. Neotropical river otters (Lontra longicaudis annectens can hold their breath for about 30 sec. Such periods of apnea may result in reduced oxygen concentration (hypoxia and reduced blood supply (ischemia to tissues. Production of adenosine 5’-triphosphate (ATP requires oxygen, and most mammalian species, like the domestic pig (Sus scrofa, are not adapted to tolerate hypoxia and ischemia, conditions that result in ATP degradation. The objective of this study was to explore the differences in purine synthesis and recycling in erythrocytes and plasma of three mammalian species adapted to different environments: aquatic (northern elephant seal (n=11, semiaquatic (neotropical river otter (n=4 and terrestrial (domestic pig (n=11. Enzymatic activity of hypoxanthine-guanine phosphoribosyltransferase (HGPRT was determined by spectrophotometry, and activity of inosine 5’-monophosphate dehydrogenase (IMPDH and the concentration of hypoxanthine (HX, inosine 5’-monophosphate (IMP, adenosine 5’-monophosphate (AMP, adenosine 5’-diphosphate (ADP, ATP, guanosine 5’-diphosphate (GDP, guanosine 5’-triphosphate (GTP, and xanthosine 5’-monophosphate (XMP were determined by high-performance liquid chromatography (HPLC. The activities of HGPRT and IMPDH and the concentration of HX, IMP, AMP, ADP, ATP, GTP and XMP in erythrocytes of domestic pigs were higher than in erythrocytes of northern elephant seals and river otters. These results suggest that under basal conditions (no diving, sleep apnea or exercise, aquatic and semiaquatic mammals have less purine mobilization than their terrestrial counterparts.

  5. Utilization of sugarcane habitat by feral pig (Sus scrofa in northern tropical Queensland: evidence from the stable isotope composition of hair.

    Directory of Open Access Journals (Sweden)

    Christopher M Wurster

    Full Text Available Feral pigs (Sus scrofa are an invasive species that disrupt ecosystem functioning throughout their introduced range. In tropical environments, feral pigs are associated with predation and displacement of endangered species, modification of habitat, and act as a vector for the spread of exotic vegetation and disease. Across many parts of their introduced range, the diet of feral pigs is poorly known. Although the remote location and difficult terrain of far north Queensland makes observing feral pig behavior difficult, feral pigs are perceived to seek refuge in World Heritage tropical rainforests and seasonally 'crop raid' into lowland sugarcane crops. Thus, identifying how feral pigs are using different components of the landscape is important to the design of management strategies. We used the stable isotope composition of captured feral pigs to determine the extent of rainforest and sugarcane habitat usage. Recently grown hair (basal hair from feral pigs captured in remote rainforest indicated pigs met their dietary needs solely within this habitat. Stable carbon and nitrogen isotope values of basal hair from feral pigs captured near sugarcane plantations were more variable, with some individuals estimated to consume over 85% of their diet within a sugarcane habitat, while a few consumed as much as 90% of their diet from adjacent forested environments. We estimated whether feral pigs switch habitats by sequentially sampling δ(13C and δ(15N values of long tail hair from a subset of seven captured animals, and demonstrate that four of these individuals moved between habitats. Our results indicate that feral pigs utilize both sugarcane and forest habitats, and can switch between these resources.

    Trichinella spp. are zoonotic parasites transmitted to humans by the consumption of raw or insufficiently cooked meat of different animal species. The most common source of infection for humans is meat from pigs and wild boar (Sus scrofa). The aim of the present work was to evaluate the incidence of Trichinella spp. infections in wild boar hunted in Latvia over a 38 year interval (1976 to 2013). A total 120,609 wild boars were individually tested for Trichinella spp. by trichinoscopy and, in case of negativity, by artificial digestion of 25 g muscles, in the 1976-2005 period, and by artificial digestion of 25-50 g muscles in the 2006-2013 period. Trichinella spp. larvae were identified at the species level by multiplex PCR. In the study period, the overall prevalence of infected wild boar was 2.5%. Trichinella britovi was the predominant (90%) species. The incidence of Trichinella spp. infection in wild boar exhibited two different trends. From 1976 to 1987, the incidence of infected/hunted wild boar increased from 0.23% to 2.56%, then it decreased to 0.19 in 1994. Thereafter, the incidence fluctuated between 0.05% and 0.37%. A statistically significant (P Latvia increased by 4.9 times and the hunting bag by 9.7 times, with a stable incidence of Trichinella spp. in the population. It follows that the biomass of Trichinella spp. larvae and of T. britovi, in particular, increased. The incidence trends of Trichinella spp. in wild boar could be related to the role played by the snow in reducing the thermal shock and muscle putrefaction which increases the survival of the larvae in muscle tissues of carrion in the 1976-1993 period; and, in the 1997-2013 period, to the increased biomass of Trichinella spp. due to the increased carnivore populations, which are the main reservoirs of these parasites.

    Full Text Available Introduction and objective. The aims of the study were: 1 to detect antibodies against T[i]oxoplasma gondii[/i] from wild boar meat; 1 establish seroprevalence of toxoplasmosis in the wild boar population; 3 establish risk factors concerned in higher possible seroprevalence; 4 to estimate the usefulness of meat juice for detection of [i]T. gondii[/i] antibodies in wild boar. Material and methods. Diaphragm meat juice samples from 656 wild boar ([i]Sus scrofa[/i] were collected during the hunting seasons between September 2008 – October 2010 from 9 districts of the Czech Republic. The samples were stratified per age category into 2 groups: piglets (n = 279 and yearlings together with adults (n = 377. The in-house ELISA test was used for the detection of antibodies against [i]T. gondii [/i]from the meat juice samples. Results. Antibodies against [i]T. gondii [/i]were detected by in-house ELISA in 260 of 656 wild boars (40% with 26% prevalence in piglets (72/279 and 50% prevalence in yearlings and adults (188/377. The district total seroprevalences ranged between 32% – 59%, with a significantly higher prevalence in the district of Havlíčkův Brod (59%. Statistically significant differences (p-value < 0.05 were found between 2 age categories, and between 9 districts, with a significant variability in the district of Havlíčkův Brod. Seroprevalence correlated positively with farm density, but without any statistical significance. Conclusion. The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

    Livestock distribution in the United States (U.S.) can only be mapped at a county-level or worse resolution. We developed a spatial microsimulation model called the Farm Location and Agricultural Production Simulator (FLAPS) that simulated the distribution and populations of individual livestock farms throughout the conterminous U.S. Using domestic pigs (Sus scrofa domesticus) as an example species, we customized iterative proportional-fitting algorithms for the hierarchical structure of the U.S. Census of Agriculture and imputed unpublished state- or county-level livestock population totals that were redacted to ensure confidentiality. We used a weighted sampling design to collect data on the presence and absence of farms and used them to develop a national-scale distribution model that predicted the distribution of individual farms at a 100 m resolution. We implemented microsimulation algorithms that simulated the populations and locations of individual farms using output from our imputed Census of Agriculture dataset and distribution model. Approximately 19% of county-level pig population totals were unpublished in the 2012 Census of Agriculture and needed to be imputed. Using aerial photography, we confirmed the presence or absence of livestock farms at 10,238 locations and found livestock farms were correlated with open areas, cropland, and roads, and also areas with cooler temperatures and gentler topography. The distribution of swine farms was highly variable, but cross-validation of our distribution model produced an area under the receiver-operating characteristics curve value of 0.78, which indicated good predictive performance. Verification analyses showed FLAPS accurately imputed and simulated Census of Agriculture data based on absolute percent difference values of farm-to-county scale. Our output data have many applications for risk management of agricultural systems including epidemiological studies, food safety, biosecurity issues, emergency

    We studied the concentration and distribution of 137 Cs and 90 Sr in the bodies of 188 wild boar (Sus scrofa Linnaeus, 1758) taken near the Chernobyl site. Of these, 111 animals were taken in the Alienation Zone, 41 animals were taken in the Permanent Control Zone and 36 animals were taken in the Periodic Control Zone. The samples included muscle and bone (rib) tissues and samples of heart, liver, lungs, kidneys, spleen, genitals and skin. The weight of the samples was 0.5 kg fresh weigh. The average concentration of 137 Cs in the muscles of the wild boar found in the Alienation Zone was 46 ± 10 kBq/kg, in the Permanent Control Zone – 13 ± 3.0 kBq/kg and in the Periodic Control Zone – 0.6 ± 0.1 kBq/kg. The largest concentration of 137 Cs was detected in the muscle tissue and kidneys taken animals. In some samples of muscle tissue it reached more than 660 kBq/kg. The 137 Cs concentrations were also high in heart and spleen up 64.3 kBq/kg and 67.5 kBq/kg – animals from the Alienation Zone and 10.3–10.6 kBq/kg – animals from the Permanent Control zone. The lowest concentration of 137 Cs was found in the lungs and skin of animals. The analyses of 90 Sr concentration in the organs and tissues of the wild boar showed that 90 Sr was concentrated mainly in the bone tissue. The average level of 90 Sr concentration in bone was 17.6 kBq/kg fresh weight animals from the Alienation Zone and 13.47 kBg/kg – animals from the Permanent Control zone. In muscle tissues and organs contained 90 Sr – 30.0–110.0 Bq/kg in the Alienation Zone and 11.0–30.0 Bq/kg in the Permanent Control zone

    Full Text Available This research is the first comparative chromosome analysis report of Thai wild boar (Sus scrofa jubatus and its relationship to domestic pig (S. s. domestica by conventional staining, G-banding and high-resolution technique. Blood samples of the Thai wild boar were taken from two males and two females kept in Nakhon Ratchasima Zoo. After standard whole blood lymphocyte culture at 37 oC for 72 hr. in the presence of colchicine, the metaphase spreads were performed on microscopic slides and airdried. Conventional staining, G-banding and high-resolution technique were applied to stain the chromosomes. The results showed that the number of diploid chromosomes of Thai wild boar was 2n (diploid = 38, and the fundamental numbers (NF were 62 in the male and female. The type of autosomes were 12 metacentric, 14 submetacentric, 4 acrocentric and 6 telocentric chromosomes, with X and Y chromosomes being metacentric chromosomes. We found that chromosomes 1, 5, 7, 8, 10, 11, 12, 13, 14, 16, 17, 18, X and Y had the same Gbanding and high-resolution technique patterns as those of domestic pig chromosomes. Chromosomes 2, 3, 4, 6, 9 and 15 are similar to those of domestic pig chromosomes. These results show the evolutionary relationship between the Thai wild boar and the domestic pig.

Determiné la variabilidad genética por análisis de PCR realizados sobre muestras de tejido provenientes de orejas de cerdos cimarrones de la Isla del Coco y cerdos domésticos del continente. Los cerdos fueron omnívoros y la categoría más importante de la dieta en ambas estaciones fue frutos. Los frutos fueron consumidos por más cerdos en la estación seca pero ocuparon mayor volumen en los estómagos en la estación húmeda. No detecté que los cerdos depredaran sobre especies animales endémicas ni que dispersaran semillas de especies exóticas. El 56 % de los cerdos cazados fueron machos y el 44 % hembras. El 46 % de las hembras en edad reproductiva estuvo preñada o lactante y el número medio de fetos por camada fue de 4.4. Confirmé un pico reproductivo en enero/febrero y no pude demostrar un pico reproductivo en junio/julio. El bajo número de fetos podría relacionarse con un estado de estrés poblacional. En general los resultados indican una reducida variabilidad genética para todos los parámetros evaluados en la población cimarrona aunque no tan baja como la esperada.

    Research on management of bovine tuberculosis (bTB) in wildlife reservoir hosts is crucial for the implementation of effective disease control measures and the generation of practical bTB management recommendations. Among the management methods carried out on wild species to reduce bTB prevalence, the control of population density has been frequently used, with hunting pressure a practical strategy to reduce bTB prevalence. However, despite the number of articles about population density control in different bTB wildlife reservoirs, there is little information regarding the application of such measures on the Eurasian wild boar (Sus scrofa), which is considered the main bTB wildlife reservoir within Mediterranean ecosystems. This study shows the effects of a management measure leading to a radical decrease in wild boar population density at a large hunting estate in Central Spain, in order to assess the evolution of bTB prevalence in both the wild boar population and the sympatric fallow deer population. The evolution of bTB prevalence was monitored in populations of the two wild ungulate species over a 5-year study period (2007-2012). The results showed that bTB prevalence decreased in fallow deer, corresponding to an important reduction in the wild boar population. However, this decrease was not homogeneous: in the last season of study there was an increase in bTB-infected male animals. Moreover, bTB prevalence remained high in the remnant wild boar population.

  15. Investigating the role of free-ranging wild boar (Sus scrofa in the re-emergence of enzootic pneumonia in domestic pig herds: a pathological, prevalence and risk-factor study.

    Directory of Open Access Journals (Sweden)

    Mainity Batista Linhares

    Full Text Available Enzootic pneumonia (EP caused by Mycoplasma hyopneumoniae has a significant economic impact on domestic pig production. A control program carried out from 1999 to 2003 successfully reduced disease occurrence in domestic pigs in Switzerland, but recurrent outbreaks suggested a potential role of free-ranging wild boar (Sus scrofa as a source of re-infection. Since little is known on the epidemiology of EP in wild boar populations, our aims were: (1 to estimate the prevalence of M. hyopneumoniae infections in wild boar in Switzerland; (2 to identify risk factors for infection in wild boar; and (3 to assess whether infection in wild boar is associated with the same gross and microscopic lesions typical of EP in domestic pigs. Nasal swabs, bronchial swabs and lung samples were collected from 978 wild boar from five study areas in Switzerland between October 2011 and May 2013. Swabs were analyzed by qualitative real time PCR and a histopathological study was conducted on lung tissues. Risk factor analysis was performed using multivariable logistic regression modeling. Overall prevalence in nasal swabs was 26.2% (95% CI 23.3-29.3% but significant geographical differences were observed. Wild boar density, occurrence of EP outbreaks in domestic pigs and young age were identified as risk factors for infection. There was a significant association between infection and lesions consistent with EP in domestic pigs. We have concluded that M. hyopneumoniae is widespread in the Swiss wild boar population, that the same risk factors for infection of domestic pigs also act as risk factors for infection of wild boar, and that infected wild boar develop lesions similar to those found in domestic pigs. However, based on our data and the outbreak pattern in domestic pigs, we propose that spillover from domestic pigs to wild boar is more likely than transmission from wild boar to pigs.

    Full Text Available Aim: The objective of this study was to investigate the chromosomal profile of indigenous pigs by computing morphometric measurements. Materials and Methods: A cytogenetic study was carried out in 60 indigenous pigs to analyze the chromosomal profile by employing the short term peripheral blood lymphocyte culture technique. Results: The modal chromosome number (2n in indigenous pigs was found to be 38 and a fundamental number of 64 as in the exotic. First chromosome was the longest pair, and thirteenth pair was the second largest while Y-chromosome was the smallest in the karyotype of the pig. The mean relative length, arm ratio, centromeric indices and morphological indices of chromosomes varied from 1.99±0.01 to 11.23±0.09, 1.04±0.05 to 2.95±0.02, 0.51±0.14 to 0.75±0.09 and 2.08±0.07 to 8.08±0.15%, respectively in indigenous pigs. Sex had no significant effect (p>0.05 on all the morphometric measurements studied. Conclusion: The present study revealed that among autosomes first five pairs were sub metacentric, next two pairs were sub telocentric (6-7, subsequent five pairs were metacentric (8-12 and remaining six pairs were telocentric (13-18, while both allosomes were metacentric. The chromosomal number, morphology and various morphometric measurements of the chromosomes of the indigenous pigs were almost similar to those established breeds reported in the literature.

    Full Text Available O objetivo desse estudo foi descrever o quadro clínico e epidemiológico, os achados patológicos, bacteriológicos e imuno-histoquímicos de um surto de pneumonia em uma granja de Javalis do Distrito Federal, Brasil. Em um período de cinco meses, morreram 90 javalis. Desses, 63 tinham lesões pulmonares. Clinicamente apresentavam atraso no desenvolvimento corporal, diminuição do apetite, letargia, tosse e dificuldade respiratória, principalmente quando movimentados. Constatou-se elevação da temperatura, 40ºC em média. Na auscultação, havia crepitações e estertores pulmonares de intensidade moderada. As alterações macroscópicas nos pulmões analisados eram típicas de broncopneumonia lobular. As lesões caracterizavam-se por consolidação crânio-ventral na maioria dos pulmões. A coloração variava de difusamente vermelho-escuro a um padrão mosaico (lóbulos vermelho-escuros intercalados por lóbulos cinzas ou difusamente acinzentados. Na maioria dos pulmões observou-se exsudato mucopurulento na luz dos brônquios e fluindo do parênquima. Histologicamente, as alterações eram de broncopneumonia purulenta e histiocitária com focos de necrose. Em alguns animais havia também hiperplasia do BALT e, na maioria dos animais, infiltração linfocítica perivascular e peribronquial. Bordetella bronchiseptica e Streptococcus spp. foram as principais bactérias isoladas. A imuno-histoquímica demonstrou a bactéria Mycoplasma hyopneumoniae no epitélio bronquiolar e bronquial e o DNA desta bactéria foi detectado pela PCR. Este é o primeiro relato de broncopneumonia em Javalis associado à infecção por M. hyopneumoniae.The aim of this paper is to describe the clinical, epidemiological, pathological, bacteriological and immunohistochemical aspects of a pneumonia outbreak in a wild pig farm in the Distrito Federal, Brazil. Ninety wild pigs died in a period of five months, and 63 of these had pulmonary lesions. Clinically, the pigs presented reduced growth rate, anorexia, lethargy, cough and dyspnea, especially after they were moved. High body temperature (40ºC in average was verified in some animals. Auscultation revealed moderate pulmonary crepitation and stertors. Pulmonary gross lesions were typical of lobular bronchopneumonia. Lung lesions were characterized by ventral-cranial consolidation in the majority of the cases. The color of affected pulmonary areas varied from diffuse dark red to mosaic pattern (dark red lobule intercalate by grayish lobule or diffusely grayish. The majority of the lungs had mucopurulent exsudate in the bronchial lumen that also drained from the parenchyma cut surface. Upon microscopy, the changes were characterized by purulent and histiocytic bronchopneumonia with necrotic foci. In some animals, there was BALT hyperplasia associated with perivascular and peribronchial plasma cells and lymphocytes infiltration in most of these cases. Bordetella bronchiseptica and Streptococcus spp. were the most frequently isolated bacteria. Immunohistochemistry evaluation demonstrated Mycoplasma hyopneumoniae on the luminal surface of bronchial and bronchiolar epithelial cells, and the DNA of bacteria was detected by PCR. This is the first report of bronchopneumonia in wild boars associated with M. hyopneumoniae infection.

    Feral pigs (S. scrofa) were introduced to the Pantanal region around 200 years ago and the population appears to be in expansion. Its eradication is considered to be impossible. The population of feral pigs in the Pantanal wetlands is currently estimated at one million. Two scientific excursions were organized. The first was conducted during the dry season, when 21 feral pigs were captured and the second was during the wet season, when 23 feral pigs were captured. Ticks were collected and the oviposition and hatching process were studied to confirm the biological success of each tick species. Three tick species were found to be feeding on feral pigs: Amblyomma cajennense, A. parvum, and Ornithodoros rostratus. During the dry season, 178 adult A. cajennense were collected, contrasting with 127 A. cajennense specimens in the wet season. This suggests that the seasonality of these ticks in the Brazilian Pantanal wetlands could be different from other regions. The results indicate that A. parvum and A. cajennense are biologically successful parasites in relation to feral pigs. A. cajennense appears to have adapted to this tick-host relationship, as well as the areas where feral pigs are abundant, and could play a role in the amplification of this tick population.

    Full Text Available Objetivou-se com esta pesquisa investigar o desenvolvimento do parênquima testicular de javalis, do nascimento aos 12 meses de idade, avaliando a evolução do processo de luminação e dos tipos celulares nos túbulos seminíferos e as proporções volumétricas dos componentes do parênquima testicular associando-os à caracterização das fases de desenvolvimento testicular. Foram utilizados 39 javalis criados em cativeiro, de zero a 12 meses de idade. Após a orquiectomia unilateral fragmentos dos testículos foram incluídos em resina plástica e as lâminas foram preparadas para as análises histométricas. A atividade espermatogênica e o processo de vacuolização epitelial iniciaram a partir dos três meses de idade. A evolução celular do epitélio seminífero foi mais intensa a partir dos nove meses, quando o processo espermatogênico apresentava-se completo e os túbulos seminíferos possuíam lume amplo. Aos 12 meses de idade, a morfologia do processo espermatogênico foi semelhante ao relatado para animais sexualmente maduros e a proporção tubular no parênquima testicular enquadrou-se ao descrito para a maioria dos mamíferos. Conclui-se que os javalis podem ser classificados quanto à fase de desenvolvimento testicular como impúberes do nascimento aos dois meses; como pré-púbere entre três e oito meses; como púberes aos nove meses; como pós-púberes entre 10 e 12 meses; e aos 12 meses apresentam características de animais sexualmente maduros.This study aimed to investigate the development of testicular parenchyma of wild boars, from the birth to 12 months old, evaluating the evolution process of lumination and the cellular types in seminiferous tubules and the volumetric proportions of testicular parenchyma components, associating them to the characterization of testicular development phases. A total of 39 wild boars raised in captivity had been used, from zero to 12 months old. After unilateral orchiectomy, fragments of the testicles were included in plastic resin and used to prepare slides for hystometric analyses. The beginning of spermatogenic activity and the epithelial vacuolization process occurred from three months of age. The cellular evolution of the seminiferous epithelium was more intense after the nine months, when the spermatogenic process is completed and the seminiferous tubules presented an ample light. At 12 months old, the morphology of spermatogenic process was similar to that reported for sexually mature animals and the tubular proportion are framed to the described for most of the mammals. It is ended that the period from the birth up to two months of age corresponded to the impubertal phase, from three to eight months to the transition from the prepubertal phase to puberty; to nine months at the puberty; and, from ten to twelve months of age to the after puberty phase, and to the 12 presented characteristics of animals sexually ripe.

O experimento foi realizado em uma área de mata, localizada nas dependências do Instituto de Pesquisa Museu Emílio Goeldi, em Belém-Pa. Foi utilizado como isca um suíno (Sus scrofa L. inteiro (com vísceras, de 14,5 Kg, recém abatido. Este foi exposto sob uma armadilha do tipo suspensa modificada, adequada à coletas de insetos adultos, sendo que também foram coletadas larvas e pupas, diretamente na carcaça. A ocorrência dos insetos adultos e de seus estágios larvais foi correlacionada com o tempo de morte do animal, a fim de possibilitar futuras inferências de tempo de morte com base na presença e dispersão destes insetos. O tempo de decomposição e a duração de cada estágio de decomposição foram registrados, tendo sido afetados provavelmente pelo tamanho da carcaça e pela estação do ano. Diferenças quanto ao padrão de sucessão não foram observadas

Todavia, somente com a análise citogenética isolada, não foi possível determinar se a origem desse polimorfismo é decorrente das hibridações com o suíno doméstico ou se são características inerentes ao javali. Contudo, quando associado a análise citogenética com as características fenotípicas, foi possível identificar a existência de hibridações. A análise citogenética nos animais submetidos a técnica de RAPD, revelou 2n=36 cromossomos nos 16 javalis assim como 2n=38 cromossomos nos 11 suínos e, por meio dessa técnica, foram possíveis agrupamentos, separando o suíno doméstico, javali e um possível híbrido revelando-se uma técnica com potencial no auxílio da identificação de híbridos.

    Porcine cysticercosis is a serious zoonosis in resource-poor countries. Despite the evidence showing that the disease is endemic in the Punjab region of India, molecular characterisation of Taenia solium cysticercosis from naturally infected pigs has not been carried out. The authors examined a total of 519 pigs slaughtered in small slaughter shops (shops that sell meat from animals that are slaughtered on the premises as the customer waits) in the urban slums of Punjab state in northern India. The expected polymerase chain reaction products with molecular sizes of 286 bp, 420 bp, 1150 bp and 333 bp corresponding to the targeted large subunit ribosomal RNA (rRNA), cytochrome oxidase 1, internal transcribed spacer 1, and diagnostic antigen Ts14 genes, respectively, were amplified from the cysts collected from all 22 infected carcasses. The detection limits for the respective primers (except those targeting the Ts14 gene) were estimated. The analytical sensitivities of both the TBR and JB primers (targeting the rRNA and cytochrome oxidase genes, respectively) were found to be higher (10 pg) than that of the internal transcribed spacer 1 gene (1 ng) primers. Ten representative samples from cytochrome oxidase 1 gene amplified products were sequenced in both directions for phylogenetic analysis. Sequencing demonstrated that all cysticerci were of the Asian genotype of T. solium and not of the African/Latin American genotype or T. asiatica. The results confirm the presence of T. solium porcine cysticercosis in Punjab state and there is therefore an urgent need for science-based policies for prevention and control of this serious zoonosis.

  11. Seroprevalence of brucellosis, tularemia, and yersiniosis in wild boars (Sus scrofa) from north-eastern Germany.

    Brucellosis and tularemia are classical zoonotic diseases transmitted from an animal reservoir to humans. Both, wildlife and domestic animals, contribute to the spreading of these zoonoses. The surveillance of the animal health status is strictly regulated for domestic animals, whereas systematic disease monitoring in wildlife does not exist. The aim of the present study was to provide data on the prevalence of anti-Brucella, anti-Francisella and anti-Yersinia antibodies in wild boars from North-Eastern Germany to assess public health risks. A total of 763 sera of wild boars from Mecklenburg-Western Pomerania hunted in 1995/1996 were tested using a commercially available Brucella suis ELISA, an in-house lipopolysaccharide (LPS)-based Francisella ELISA, and commercially available Western blot kits for the detection of anti-Francisella and anti-Yersinia antibodies. The Yersinia enterocolitica O:9 LPS is able to induce serological cross-reactions indistinguishable from brucellosis due to a similar immunodominant epitope in the Brucella O-polysaccharide. The Yersinia Western blot assay was, therefore, based on five recombinant Yersinia outer proteins which have been proved to be specific for the serodiagnosis of yersiniosis. Anti-Brucella, anti-Francisella and anti-Yersinia antibodies were detected in 22.0%, 3.1%, and 62.6% of the wild boars, respectively. The high seroprevalence of tularemia and brucellosis in wild boars indicates that natural foci of these zoonoses are present in wildlife in Germany. However, the impact of transmission of zoonotic pathogens from wildlife to livestock is unknown. Only careful and systematic monitoring will help to prevent the (re)emergence of these zoonotic diseases in domestic animals and consequently human infection.

    preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp). The forensically dominant fly was C. rufifacies, while the beetle was D. maculatus. The beetles associated with pig carcasses found in this study are first reported in Phitsanulok, Thailand. In addition, ants, bees, spiders and millipedes were also associated with the carcasses. These findings may provide data for further use in legal investigations in Thailand.

    Full Text Available Conjunctival swabs from 44 free-living wild boars culled during a demographic control programme applied in a Regional Park located in the Northern Italy were examined by 16S rRNA encoding gene nested PCR. In total, 22 (50% wild boars were PCR positive. Sequencing of the amplicons identified Chlamydia suis and Chlamydia pecorum in 12 and 5 samples, respectively. For one sample found PCR positive, the nucleotide sequence could not be determined. Four conjunctival samples showed ≥ 92% sequence similarities to 16S rRNA sequences from Chlamydia-like organisms, as did large intestine, uterus, and vaginal swabs from the same four animals. Amoeba DNA was found in one Chlamydia-like organism positive conjunctival swab. To our knowledge, this is the first detection of members of the Parachlamydiaceae family in wild boars, confirming a large animal host range for Chlamydia-like organisms.

    Full Text Available Abstract Quantitative trait loci (QTL affecting carcass and meat quality located on SSC2 were identified using variance component methods. A large number of traits involved in meat and carcass quality was detected in a commercial crossbred population: 1855 pigs sired by 17 boars from a synthetic line, which where homozygous (A/A for IGF2. Using combined linkage and linkage disequilibrium mapping (LDLA, several QTL significantly affecting loin muscle mass, ham weight and ham muscles (outer ham and knuckle ham and meat quality traits, such as Minolta-L* and -b*, ultimate pH and Japanese colour score were detected. These results agreed well with previous QTL-studies involving SSC2. Since our study is carried out on crossbreds, different QTL may be segregating in the parental lines. To address this question, we compared models with a single QTL-variance component with models allowing for separate sire and dam QTL-variance components. The same QTL were identified using a single QTL variance component model compared to a model allowing for separate variances with minor differences with respect to QTL location. However, the variance component method made it possible to detect QTL segregating in the paternal line (e.g. HAMB, the maternal lines (e.g. Ham or in both (e.g. pHu. Combining association and linkage information among haplotypes improved slightly the significance of the QTL compared to an analysis using linkage information only.

    Epidemiological studies have reported an association between high iron (Fe) levels and elevated risk of developing type 2 diabetes mellitus (T2D). It is believed that the formation of Fe-catalyzed hydroxyl radicals may contribute to the development of diabetes. Our goal was to determine the effect of a diet with a high Fe content on type 2 diabetic pigs. Four groups of piglets were studied: (1) control group, basal diet; (2) Fe group, basal diet with 3,000 ppm ferrous sulfate; (3) diabetic group (streptozotocin-induced type 2 diabetes) with basal diet; (4) diabetic/Fe group, diabetic animals/3,000 ppm ferrous sulfate. For 2 months, biochemical and hematological parameters were evaluated. Tissue samples of liver and duodenum were obtained to determine mRNA relative abundance of DMT1, ferroportin (Fpn), ferritin (Fn), hepcidin (Hpc), and transferrin receptor by qRT-PCR. Fe group presented increased levels of hematological (erythrocytes, hematocrit, and hemoglobin) and iron parameters. Diabetic/Fe group showed similar behavior as Fe group but in lesser extent. The relative abundance of different genes in the four study groups yielded a different expression pattern. DMT1 showed a lower expression in the two iron groups compared with control and diabetic animals, and Hpc showed an increased on its expression in Fe and diabetic/Fe groups. Diabetic/Fe group presents greater expression of Fn and Fpn. These results suggest that there is an interaction between Fe nutrition, inflammation, and oxidative stress in the diabetes development.

    In many parts of the developing world, pigs are kept under low-input systems where they roam freely to scavenge food. These systems allow poor farmers the opportunity to enter into livestock keeping without large capital investments. This, combined with a growing demand for pork, especially in urban areas, has led to an increase in the number of small-holder farmers keeping free range pigs as a commercial enterprise. Despite the benefits which pig production can bring to a household, keeping pigs under a free range system increases the risk of the pig acquiring diseases, either production-limiting or zoonotic in nature. This study used Global Positioning System (GPS) technology to track free range domestic pigs in rural western Kenya, in order to understand their movement patterns and interactions with elements of the peri-domestic environment. We found that these pigs travel an average of 4,340 m in a 12 hr period and had a mean home range of 10,343 m(2) (range 2,937-32,759 m(2)) within which the core utilisation distribution was found to be 964 m(2) (range 246-3,289 m(2)) with pigs spending on average 47% of their time outside their homestead of origin. These are the first data available on the home range of domestic pigs kept under a free range system: the data show that pigs in these systems spend much of their time scavenging outside their homesteads, suggesting that these pigs may be exposed to infectious agents over a wide area. Control policies for diseases such as Taenia solium, Trypanosomiasis, Trichinellosis, Toxoplasmosis or African Swine Fever therefore require a community-wide focus and pig farmers require education on the inherent risks of keeping pigs under a free range system. The work presented here will enable future research to incorporate movement data into studies of disease transmission, for example for the understanding of transmission of African Swine Fever between individuals, or in relation to the life-cycle of parasites including Taenia solium.

    Intrauterine growth restriction (IUGR) may elicit a series of postnatal body developmental and metabolic diseases due to their impaired growth and development in the mammalian embryo/fetus during pregnancy. In the present study, we hypothesized that IUGR may lead to abnormally regulated DNA methylation in the intestine, causing intestinal dysfunctions. We applied reduced representation bisulfite sequencing (RRBS) technology to study the jejunum tissues from four newborn IUGR piglets and their normal body weight (NBW) littermates. The results revealed extensively regional DNA methylation changes between IUGR/NBW pairs from different gilts, affecting dozens of genes. Hiseq-based bisulfite sequencing PCR (Hiseq-BSP) was used for validations of 19 genes with epigenetic abnormality, confirming three genes (AIFM1, MTMR1, and TWIST2) in extra samples. Furthermore, integrated analysis of these 19 genes with proteome data indicated that there were three main genes (BCAP31, IRAK1, and AIFM1) interacting with important immunity- or metabolism-related proteins, which could explain the potential intestinal dysfunctions of IUGR piglets. We conclude that IUGR can lead to disparate DNA methylation in the intestine and these changes may affect several important biological processes such as cell apoptosis, cell differentiation, and immunity, which provides more clues linking IUGR and its long-term complications.

    2009-01-01

    Full Text Available Three feral pig populations inhabiting contrasting environments along the north easterncoast of Australia have been investigated with respect to population structure, individual condition andreproduction. The population on Prince of Wales Island contains a large proportion of juvenile andsub-adult pigs but lacks pigs in the higher age classes. Individuals also breed at an earlier age thananimals of the mainland populations. Pig populations on Cape York Peninsula show a largerproportion of older animals and feral pigs living in rainforest habitats show a low proportion ofanimals in very young and very old age classes. Pigs from the lowland rainforest population are inbetter condition than those of the other populations for most of the year, reflecting the availability offood all year round in this environment. Differences in the population structure of the threepopulations are discussed with respect to fecundity and several mortality factors such as predation anddiseases/parasites.

    Full Text Available In the present study we examined the brain of fetal, newborn, and adult pigs raised for meat production. The fresh and formalin-fixed weights of the brain have been recorded and used, together with body weight, to calculate the Encephalization Quotient (EQ. The weight of the cerebellum has been used to calculate the Cerebellar Quotient (CQ. The results have been discussed together with analogue data obtained in other terrestrial Cetartiodactyla (including the domestic bovine, sheep, goat, and camel, domesticated Carnivora, Proboscidata, and Primates. Our study, based on a relatively large experimental series, corrects former observations present in the literature based on smaller samples, and emphasizes that the domestic pig has a small brain relative to its body size (EQ = 0.38 for adults, possibly due to factors linked to the necessity of meat production and improved body weight. Comparison with other terrestrial Cetartiodactyla indicates a similar trend for all domesticated species.

    Full Text Available The article presents a comparative analysis of four methods for quantifying the protein-peptide complexes content in extracts obtained from animal raw materials, as well as the low- and highmolecular weight extract fractions: the direct spectrophotometric determination at wavelengths of 260 and 280 nm with subsequent calculation by the Kalckar formula; the biuret reaction by the Kingsley-Weichselbaum method; the method with Bradford reagent and the standard Lowry method. Experimental data analysis demonstrates that in case of the extract that contains protein-peptidic complexes in different molecular weights range, the Kingsley-Weichselbaum method shows the highest quality of protein concentration determination; while studying highmolecular weight fraction (more than 30 kDa, it is possible to obtain more information by combining the spectrophotometric method and the Kingsley-Weichselbaum method. Low-molecular weight fractions (less than 30 kD should be investigated by complex methods including the spectrophotometric method, Lowry and Bradford methods. These methods make it possible to presumably estimate protein molecules size ranges (by amount of peptide bonds, and also to determine hydrophobic and aromatic amino acids presence.

    Wild boar is a highly polycotous ungulate species, characterized by a complex and dynamical social organization based on the maintenance of long-term bonds between mother and daughters. The roots of this social organization have to be researched at the individual level, considering adaptations that improve fitness in hostile environments. We used information collected by camera-traps at artificial feeding sites, in two contrasting environments in Bulgaria (mountain habitat) and Italy (sub-Mediterranean habitat). We recorded 417 and 885 distinct groups on 7 and 11 foraging sites in Bulgaria and Italy, respectively. We computed (controlling for time range, study area and supplementary feeding site) an index of effective foraging time of the different social groups. We observed a positive and significant effect of the number of conspecifics of the same social group on the effective foraging time. The impact of the other social classes on effective foraging time is also positive, and males, yearlings, and juveniles benefited more from the presence of other social classes, while females were less affected. The access of the different social groups to foraging sites is not random. Males and yearlings play producers (i.e., search for food) and are prone to attend foraging sites before adult females and subadults, so attaining a larger foraging efficiency with respect to a situation where other groups are already present on the feeding site. Wild boars exhibit a more complex social organisation than previously believed, where cooperation prevails largely on competition. A rough division of labour is also present: yearlings, males, and juveniles use to play producers and assume a significant amount of risk determined by the presence of predators or hunters.

    Full Text Available The objective of this systematic scientific review was updated bibliographic information concerning the genetic, morphological, zootechnical and meat potential of creole pigs in Central and South America. It was found a population of 73 million Creoles pigs in Latin America, most under extensive, and semi extensive production systems. Since its European origin, adaptation to different ecosystems on the continent and the introduction of new breeds has led into a wide variety of creole pigs. Adaptation and introduction of breeds have led also in a rise of genetic variability of pigs benefiting the rusticity that involves a more efficient immune system. In the same way as omnivore the creole pig had a good adaptation to different diets, getting better advantage of fibrous and fatty food than commercial breeds. On the other hand, creole pigs showed an acceptable reproductive performance, distinguished by sexual precocity and high feasibility of weaning, nevertheless its growth was slow and lactation periods were long. Regarding to the quality of meat cuts , it has not been disadvantaged, if we take into account subjective criteria as well as tenderness and the nutritional value, characteristics that give higher economic value outstripping commercial pig meat.

    Tail biting in pigs is a major welfare problem within the swine industry. Even though there is plenty of information on housing and management-related risk factors, the biological bases of this behavioral problem are poorly understood. The aim of this study was to investigate a possible link between tail biting, based on behavioral recordings of pigs during an ongoing outbreak, and certain neurotransmitters in different brain regions of these pigs. We used a total of 33 pigs at a farm with a long-standing problem of tail biting. Three equally big behavioral phenotypic groups, balanced for gender and age were selected, the data thus consisting of 11 trios of pigs. Two of the pigs in each trio originated from the same pen: one tail biter (TB) and one tail biting victim (V). A control (C) pig was selected from a pen without significant tail biting in the same farm room. We found an effect of tail biting behavioral phenotype on the metabolism of serotonin and dopamine, with a tendency for a higher 5-HIAA level in the prefrontal cortex (PFC) of TB compared to the other groups, while V pigs showed changes in both serotonin and dopamine metabolism in the striatum (ST) and limbic cortex (LC). Trp:BCAA and Trp:LNAA correlated positively with serotonin and 5-HIAA in the PFC, but only in TB pigs. Furthermore, in both ST and LC, several of the neurotransmitters and their metabolites correlated positively with the frequency of bites received by the pig. This is the first study indicating a link between brain neurotransmission and tail biting behavior in pigs with TB pigs showing a tendency for increased PFC serotonin metabolism and V pigs showing several changes in central dopamine and serotonin metabolism in their ST and LC, possibly due to the acute stress caused by being bitten.

    Sequence of depolarization of myocardium of pig heart ventricles was studied by the method of multichannel synchronous cardioelectrotopography. There is established formation of areas of early depolarization in subendocardium of interventricular septum and in the base of left ventricle papillary muscles; of multiple foci--in the depth of walls; of areas of late depolarization--in subepicardium of the left ventricle dorsolateral side. As compared with other species of ungulate animals (reindeer and sheep, in pig heart ventricles, differences are revealed in locations of early and late depolarization, a breakdown of the excitation wave into subepicardium.

    Pigs were infected with a Bolivian strain of Trypanosoma cruzi (genotype I) and evaluated up to 150 days postinoculation (dpi) to determine the use of pigs as an animal model of Chagas disease. Parasitemia was observed in the infected pigs during the acute phase (15–40 dpi). Anti-T.cruzi immunoglobulin M was detected during 15–75 dpi; high levels of anti-T.cruzi immunoglobulin G were detected in all infected pigs from 75 to 150 dpi. Parasitic DNA was observed by western blot (58%, 28/48) and polymerase chain reaction (27%, 13/48) in urine samples, and in the brain (75%, 3/4), spleen (50%, 2/4), and duodenum (25%, 1/4), but no parasitic DNA was found in the heart, colon, and kidney. Parasites were not observed microscopically in tissues samples, but mild inflammation, vasculitis, and congestion was observed in heart, brain, kidney, and spleen. This pig model was useful for the standardization of the urine test because of the higher volume that can be obtained as compared with other small animal models. However, further experiments are required to observe pathological changes characteristic of Chagas disease in humans. PMID:26928841

Como ocurre con otras ciencias interfacultativas o interdisciplinales la Etnobotánica no se puede definir fácilmente y por esto ha habido muchas diferencias de opinión en cuanto a su alcance y sus objetos. En su más amplio sentido, la Etnobotánica es el estudio de las relaciones que existen entre el hombre y su ambiente vegetal, es decir las plantas que lo rodean. En un sentido más restringido, se ha considerado solamente como el estudio del uso de las plantas cultivadas y silvestres por los pueblos primitivos, usualmente los aborígenes.

    Full Text Available El "coro" es un tabaco silvestre de Argentina y Chile cuyas raíces son empleadas como fumatorio y mascatorio desde tiempos inmemoriales por grupos indígenas. Si bien existen noticias sobre su empleo desde la época colonial, en la actualidad no hay consenso sobre su identidad botánica a la par que sus modalidades de obtención, procesado y consumo han sido escasamente descriptas. Se efectuaron campañas etnobotánicas al sudoeste de la provincia del Chaco donde se colectaron ejemplares que responden a dicho nombre vernáculo en compañía de indígenas y se analizaron fuentes bibliográficas históricas disponibles. Se comprobó in situ que los mocovíes actualmente fuman sus raíces mezcladas con tabaco tanto en contextos ceremoniales como extra-ceremoniales. Como resultado del análisis bibliográfico se infiere que también lo emplearon en el pasado de manera homóloga indígenas vilelas, qom (tobas; wichi y abipones. Se descarta la correspondencia del "coro" con especies de Trichocline por la inexistencia de registros etnobotánicos al respecto. Se confirma que este fumatorio corresponde a Nicotiana paa Mart. rov. y se presentan y discuten nuevos datos sobre su obtención, procesamiento y consumo.

    Full Text Available La recolección y venta de hongos silvestres comestibles, junto con la de otros productos forestales no maderables, constituyen una estrategia alimentaria y de subsistencia para los productores rurales. A pesar de la importancia social, económica, ecológica y cultural, dichas actividades todavía son de las más aisladas y poco conocidas del sector primario nacional. Esto trae como consecuencia la ausencia de políticas, esquemas de apoyo y estrategias de desarrollo para tales actividades. Por lo anterior, el objetivo de este trabajo fue exponer la necesidad de generar estadísticas oficiales en la recolección de hongos y establecer la relación entre la investigación científica, políticas públicas y el marco legal vigente, con el fin de conocer el estado actual de esta actividad y sus perspectivas a futuro. Se observa que el desconocimiento de la recolección de hongos ocasiona que no se le considere y excluya de las políticas de desarrollo del gobierno y de los sectores social y privado. De la misma manera, la falta de información, gestión y vinculación causa el rezago de la recolección y, con ello, su eventual sustitución o reemplazo por otras actividades. Sin embargo, existen ciertas potencialidades que debidamente manejadas pueden representar una alternativa real en el manejo sustentable de los bosques de México.

    Pigs have played a major role in the economic, social and symbolic systems of China since the Early Neolithic more than 8,000 years ago. However, the interaction between the history of pig domestication and transformations in Chinese society since then, have not been fully explored. In this paper, we investigated the co-evolution from the earliest farming communities through to the new political and economic models of state-like societies, up to the Chinese Empire, using 5,000 years of archaeological records from the Xiawanggang (XWG) and Xinzhai (XZ) sites (Henan Province). To trace the changes of pig populations against husbandry practices, we combined the geometric morphometric analysis of dental traits with a study of the stable carbon and nitrogen isotope ratios from bone collagen. The domestication process intensified during the Neolithic Yangshao, prompted by greater selective pressure and/or better herd control against wild introgression. After that, pig farming, in XWG, relied on local livestock and a gradual change of husbandry practices overtime. This was characterized by a gentle increase in millet foddering and animal protein intake, until a complete change over to household management during the Han dynasty. The only rupture in this steady trend of husbandry occurred during the Longshan period, with the appearance of small sized and idiosyncratic pigs with specific feeding practices (relying on millet and household scraps). From three exploratory hypothesis, we explored the possibility of anti-elite pig production in XWG during the Longshan period, as a means to resist incorporation into a new economic model promoting intensified domestic production. This exploratory hypothesis is the most suitable to our dataset; however, numerous areas need to be explored further in order to adequately document the role of pigs in the rise of China's complex societies.

    The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

    Investigations of seasonal feed choice of a wild boar have been carried out during a 3-year period on the basis of the stomach content. Results of the investigations are given. A list of forage plants and forage animals is presented. Seasonal intensity of their consumption is evaluated. Main plant assemblages of the exclusion zone of the Chernobyl accident are analyzed for their significance in the diet of a wild boar. Special attention is paid to the role of underground forage (35% of average annual forage), and to consumption of Oenotera biennis roots comprising 26% of average annual forage. Recent state of the forage base and of the wild boar population is estimated. An attempt to predict its dynamics for the nearest 10-15 years is made

Esta espécie colonizou as carcaças de porcos do estágio enfisematoso à esqueletização. Adultos foram observados eventualmente predando larvas de moscas a partir do segundo dia de intervalo pós-morte e suas larvas foram observadas a partir do quinto dia se alimentando em áreas esqueletizadas, provavelmente limpando os ossos dos tecidos moles remanescentes. O comportamento predatório dos adultos nas larvas de dípteros mais velhas podem impactar suas populações e complicar estimativas de intervalo pós-morte, uma vez que estas são freqüentemente usadas para esta estimativa. Além disso, adultos e larvas têm potencial uso como indicadores de intervalo pós-morte (IPM porque o adulto pode colonizar carcaças do segundo dia em diante e as larvas do quinto dia em diante.

    Full Text Available Our aim was to evaluate the risk of human toxoplasmosis via meat consumption from wild boars by estimating the seroprevalence of Toxoplasma gondii in animals hunted in central Italy. Using a modified agglutination test, 213 sera from wild boars were examined for anti-Toxoplasma IgG antibodies. Diaphragm samples (n=65 from seropositive and seronegative animals were tested by nested-PCR to detect T. gondii DNA. Toxoplasma DNA from diaphragms was genotyped by PCR-RFLP using 12 genetic markers. Moreover, the aim of the study was also to identify helminth infections of wild boars in the selected area and to evaluate their hazard for humans. Examination of sera revealed a seroprevalence of 12.2%. Only one T. gondii strain could be genotyped from a seropositive animal and PCR-RFLP revealed that it belonged to type II. Analysis of 50 samples of faeces and 32 small intestines revealed that 78% and 15.6% of the samples harboured parasites, respectively, with the occurrence of parasites potentially dangerous for humans. These latter included Ascaris suum, Macracanthorhynchus hirudinaceus, Trichuris suis, and Metastrongylus spp. A significant association was found between coprological positivity and male sex. These results indicate that T. gondii infection may be present in wild boar tissues and consumption of undercooked or raw wild boar meat may expose humans to risk of toxoplasmosis in the study area. Furthermore, the study highlights that wild boars are hosts of helminths of veterinary and medical importance transmissible to pigs and humans.

    Full Text Available Blood samples for determining of epinephrine concentration and biochemical parameters in the blood serum of wild boars were taken from 42 healthy wild boars, both sexes, during the hunting season. All animals in good condition, body weight 20 to 95 kg, were divided into two groups up to 50 kg (group A and up to 95 kg (Group B. Epinephrine concentration was determined by ELISA twice: one week after taking samples and a month after repeated freezing at -80°C. It was higher in relation to the reference value of domestic pigs and human (109.45 pg/ml in A and 119.54 pg/ml in B group. Repeated freezing and re-analysis after a month were resulted in lower concentrations of epinephrine (12% in young and 11.17% in adult animal, but without statistical significance (P>0.05. Biochemical analysis results’ show increased glucose and triglycerides concentrations compared to the reference values, while other indicators were observed within or slightly increased referring to the normal range. The correlation between glucose and epinephrine was not determined.

    Full Text Available The diversity of olfactory binding proteins (OBPs is a key point to understand their role in molecular olfaction. Since only few different sequences were characterized in each mammalian species, they have been considered as passive carriers of odors and pheromones. We have explored the soluble proteome of pig nasal mucus, taking benefit of the powerful tools of proteomics. Combining two-dimensional electrophoresis, mass spectrometry and western-blot with specific antibodies, our analyses revealed for the first time that the pig nasal mucus is mainly composed of secreted OBP isoforms, some of them being potentially modified by O-GlcNAcylation. An ortholog gene of the glycosyltransferase responsible of the O-GlcNAc linking on extracellular proteins in Drosophila and Mouse (EOGT was amplified from tissues of pigs of different ages and sex. The sequence was used in a phylogenetic analysis, which evidenced conservation of EOGT in insect and mammalian models studied in molecular olfaction. Extracellular O-GlcNAcylation of secreted OBPs could finely modulate their binding specificities to odors and pheromones. This constitutes a new mechanism for extracellular signaling by OBPs, suggesting that they act as the first step of odor discrimination.

    The aim of this study was to detect the presence and determine the residue levels of DDT, lindane, endrin and polychlorinated biphenyls (PCBs) in the liver of wild boars from the area of West Pomerania, NW Poland; to determine the activity of glutathione S-transferase (GST) as a biomarker of biological response and to assess the toxicological risk for consumers of the wild boar offal. The presence of pesticide residues and PCBs was found in all examined liver samples. The highest concentration was observed for endrin, and then, the descending order was PCBs >DDTs >lindane >dl-PCBs. The mean hepatic concentrations of endrin, PCBs, DDTs and lindane were 117.28, 78.59, 67.95 and 7.24 ng/g lipid weight, respectively. Among the dioxin-like PCB congeners, 118 and 156 were dominant in liver samples. The mean toxic equivalent (TEQ) level calculated for dl-PCBs was 2.10 ± 1.11 pg WHO-PCB-TEQ/g. There was a statistically significant (p < 0.05) negative correlation between the concentration of lindane, DDTs and PCBs (as a sum of indicator congeners) in the liver and in the activity of GST. However, GST activities showed no significant correlation with any of the dl-PCBs. In five boar liver samples, the levels of certain organochlorine compounds exceeded the maximum residue levels (MRLs). In one sample, the MRLs were exceeded simultaneously for PCBs, endrin and DDTs and in another one-for endrin and DDTs. In the remaining three samples, only PCB levels were exceeded.

    During disease outbreaks, core temperature is a useful health metric in swine, due to the presence of pyrexia especially during the acute phase of infection. Despite technologic advances in other facets of swine production and health management, rectal thermometry continues to be the 'gold standard' for measuring core body temperature. However, for various reasons, collecting rectal temperatures can be difficult and unsafe depending on the housing modality. In addition, the delay between insertion of the rectal thermometer and obtaining a reading can affect measurement accuracy, especially when the pig requires physical restraint. Clearly safer, faster, and more accurate and precise temperature acquisition methods that necessitate minimal or no handling of swine are needed. We therefore compared rectal thermometers, subcutaneous microchips, and an inexpensive handheld infrared thermometer by measuring the core body temperature of 24 male castrated piglets at random intervals over a 5-wk period. The core body temperature (mean ± 1 SD) was 39.3±0.5 °C by rectal thermometry, 39.0±0.7 °C by microchip transponder, and 34.3±1.0 °C by infrared thermometry; these 3 values differed significantly. Although the readings obtain by using infrared thermometry were numerically lower than those from the other methods, it is arguably the safest method for assessing the core temperature of swine and showed strong relative correlation with rectal temperature.

    Full Text Available The identification of the genotypes of Echinococcus granulosus present in livestock and wild animals within regions endemic for cystic echinococcosis (CE is epidemiologically important. Individual strains display different biological characteristics that contribute to outbreaks of CE and that must be taken into account in the design of intervention programs. In this study, samples of hydatid cysts due to E. granulosus were collected from alpacas (4 in Puno and pigs (8 in Ayacucho in Peru, an endemic region for CE. Polymerase chain reaction amplification and DNA sequencing of specific regions of the mitochondrial cytochrome C oxidase subunit 1 and NADH dehydrogenase subunit 1 genes confirmed the presence of a strain common to sheep, the G1 genotype, in alpacas. Two different strains of E. granulosus were identified in pigs: the G1 and the G7 genotypes. This is the first report of the G1 genotype of E. granulosus in alpacas in endemic regions of CE in Peru.

    Full Text Available Abstract Background Epidemiologic data collected during epidemics in the western United States combined with limited experimental studies involving swine and cattle suggest that host predilection of epidemic vesicular stomatitis New Jersey virus (VSNJV strains results in variations in clinical response, extent and duration of virus shedding and transmissibility following infection in different hosts. Laboratory challenge of livestock with heterologous VSNJV strains to investigate potential viral predilections for these hosts has not been thoroughly investigated. In separate trials, homologous VSNJV strains (NJ82COB and NJ82AZB, and heterologous strains (NJ06WYE and NJOSF [Ossabaw Island, sand fly] were inoculated into cattle via infected black fly bite. NJ82AZB and NJ06WYE were similarly inoculated into swine. Results Clinical scores among viruses infecting cattle were significantly different and indicated that infection with a homologous virus resulted in more severe clinical presentation and greater extent and duration of viral shedding. No differences in clinical severity or extent and duration of viral shedding were detected in swine. Conclusions Differences in clinical presentation and extent and duration of viral shedding may have direct impacts on viral spread during epidemics. Viral transmission via animal-to-animal contact and insect vectored transmission are likely to occur at higher rates when affected animals are presenting severe clinical signs and shedding high concentrations of virus. More virulent viral strains resulting in more severe disease in livestock hosts are expected to spread more rapidly and greater distances during epidemics than those causing mild or inapparent signs.

    Pigs have played a major role in the economic, social and symbolic systems of China since the Early Neolithic more than 8,000 years ago. However, the interaction between the history of pig domestication and transformations in Chinese society since then, have not been fully explored. In this paper, we investigated the co-evolution from the earliest farming communities through to the new political and economic models of state-like societies, up to the Chinese Empire, using 5,000 years of archaeological records from the Xiawanggang (XWG) and Xinzhai (XZ) sites (Henan Province). To trace the changes of pig populations against husbandry practices, we combined the geometric morphometric analysis of dental traits with a study of the stable carbon and nitrogen isotope ratios from bone collagen. The domestication process intensified during the Neolithic Yangshao, prompted by greater selective pressure and/or better herd control against wild introgression. After that, pig farming, in XWG, relied on local livestock and a gradual change of husbandry practices overtime. This was characterized by a gentle increase in millet foddering and animal protein intake, until a complete change over to household management during the Han dynasty. The only rupture in this steady trend of husbandry occurred during the Longshan period, with the appearance of small sized and idiosyncratic pigs with specific feeding practices (relying on millet and household scraps). From three exploratory hypothesis, we explored the possibility of anti-elite pig production in XWG during the Longshan period, as a means to resist incorporation into a new economic model promoting intensified domestic production. This exploratory hypothesis is the most suitable to our dataset; however, numerous areas need to be explored further in order to adequately document the role of pigs in the rise of China’s complex societies.

    Full Text Available vThis study was aimed at analysing the most relevant environmental variables involved in vehicle–wild boar road collisions in a Mediterranean area, starting from a territorial information system implemented in a GIS environment. Landscape structure indices and local qualitative and quantitative variables were correlated to identify the most frequent predisposing factors of collisions. Statistical tests of the considered parameters indicated a higher frequency of collisions in the evening hours of late summer and autumn (P<0.05 compared with daytime and night-time, localized nearness to attraction points (feeding or resting sites; P<0.001 and closeness to no-hunting areas (P<0.001. In addition, local road parameters (shape of road, visibility at road sides, etc. considerably increased the risk of collisions.

    Mitral regurgitation (MR) is a common heart-valve lesion after myocardial infarction in humans. Because it is considered a risk factor for accelerated heart failure and death, various surgical approaches and catheter-based devices to correct it are in development. Lack of a reproducible animal model of MR after myocardial infarction and reliable techniques to perform open-heart surgery in these diseased models led to the use of healthy animals to test new devices. Thus, most devices that are deemed safe in healthy animals have shown poor results in human efficacy studies, hampering progress in this area of research. Here we report our experience with a swine model of postinfarction MR, describe techniques to induce regurgitation and perform open-heart surgery in these diseased animals, and discuss our outcomes, complications, and solutions.

    Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences were detected between the 2 groups for mean arterial pressure, cardiac output, respiratory rate, lactate, or pH. Both hydroxocobalamin and cobinamide rescued severely cyanide-poisoned swine from apnea in the absence of assisted ventilation. The dose of cobinamide was one fifth that of hydroxocobalamin.

    The objective of this study was to identify the bioserotypes and virulence markers of Yersinia enterocolitica strains isolated from wild boars in Poland. Bacteriological examination of 302 rectal swabs from 151 wild boars resulted in the isolation of 40 Y. enterocolitica strains. The majority of the examined strains (n = 30), belonged to bioserotype 1A/NI. The presence of individual Y. enterocolitica strains belonging to bioserotypes 1B/NI (3), 1A/O:8 (2), 1A/O:27 (2), 2/NI (1), 2/O:9 (1) and 4/O:3 (1) was also demonstrated. Amplicons corresponding to ail and ystA genes were observed only in one Y. enterocolitica strain--bioserotype 4/O:3. The ail and ystB gene amplicons were noted in 11 Y. enterocolitica biotype 1A strains, although single amplicons of ystB gene were found in 28 of the tested samples. In four out of eight cases when two Y. enterocolitica strains were isolated from the same animal, the strains differed in biotype, serotype or virulence markers. The European population of wild boars continues to grow and spread to new areas, therefore, wild boars harbouring potentially pathogenic Y. enterocolitica 4/O:3 strains pose a challenge to public health.

Por lo anterior, se estableció una multiplicación y crianza de cochinilla silvestre, proveniente de la zona árida del norte de México para caracterizarla, utilizando como hospedero a Opuntia megacantha Salm Dyck. Los resultados indican que la especie silvestre pertenece al género-especie Dactylopius opuntia. Se determinó la presencia de partenogénesis en hembras. La duración de los estadios biológicos depende del sexo del insecto; el adulto hembra permaneció durante 38.4 días y 4.2 días para machos, los primeros estadios ninfales fueron similares en duración (18.1-19.8 días. El ciclo biológico de las hembras fue de 77 días mientras que el de los machos fue de 43 días. Para las hembras se estimó un periodo de preoviposición de 18.8 días, manteniéndose en oviposición durante 21 días con un promedio de 131 insectos por hembra. La proporción sexual hembras: machos fue 1:1. El tipo de reproducción fue predominantemente sexual, aunque hubo hembras partenogénicas.

The objective of this study was to identify the origin of a group of Chilean accessions based on their genetic relationship with wild material from the Mesoamerican and Andean common bean gene pool. To achieve this objective, universal primers of chloroplast DNA (cpDNA and mitochondrial DNA (mtDNA were used to detect polymorphism using Polymerase Chain Reaction - Restriction Fragment Length Polymorphism (PCR-RFLP. Thirty-two genotypes were analyzed, including wild material from Mexico, Ecuador, Peru, Bolivia, and Argentina, as well as Chilean cultivated genotypes belonging to endemic Chilean accession types (Tórtola, Coscorrón, and Cuyano and naturalized commercial lines (Frutilla, Bayo, Manteca, and Blanco grande. Results showed a low level of polymorphism for cpDNA (23% and mtDNA (24% in wild and cultivated Chilean common bean accessions. Some universal primers and restriction enzyme combinations were more efficient than others in detecting polymorphism. The Chilean materials were closely related to wild accessions collected in Argentina, Bolivia, and Peru indicating their Andean origin.

MÉTODOS Estudo descritivo do surto de febre amarela silvestre na região sudoeste do estado, entre fevereiro e abril de 2009. Foram avaliados casos suspeitos e confirmados em humanos e primatas não humanos. A investigação entomológica, em ambiente silvestre, envolveu captura em solo e copa de árvore para identificação das espécies e detecção de infecção natural. Foram realizadas ações de controle de Aedes aegypti em áreas urbanas. A vacinação foi direcionada para residentes dos municípios com confirmação de circulação viral e nos municípios contíguos, conforme recomendação nacional. RESULTADOS Foram confirmados 28 casos humanos (letalidade 39,3% em áreas rurais de Sarutaiá, Piraju, Tejupá, Avaré e Buri. Foram notificadas 56 mortes de primatas não humanos, 91,4% do gênero Alouatta sp . A epizootia foi confirmada laboratorialmente em dois primatas não humanos, sendo um em Buri e outro em Itapetininga. Foram coletados 1.782 mosquitos, entre eles Haemagogus leucocelaenus , Hg. janthinomys/capricornii , Sabethes chloropterus , Sa. purpureus e Sa. undosus . O vírus da febre amarela foi isolado de um lote de Hg. leucocelaenus procedente de Buri.

    Full Text Available Resumen:Cambios en el uso del suelo son principalmente consecuencia de las acciones antropogénicas. La actual transformación agrícola y urbana en Costa Rica ha generado preguntas acerca de la efectividad de la conservación y restauración dentro de las áreas protegidas. En este documento nosotros analizamos los patrones de cambio del uso del suelo entre tres periodos: 1997, 2005 y 2010 en términos de magnitud, dirección y velocidad a través de mapas categóricos generados por la foto-interpretación para dos áreas silvestres protegidas y sus áreas aledañas: Parque Nacional La Cangreja (LCNP, el Refugio de Vida Silvestre Rancho Mastatal (RMWR y sus áreas aledañas (SA, esta última compuesta por área de un kilómetro de radio fuera de los límites de las áreas protegidas. La matriz que describe el paisaje dentro de las áreas protegidas es la cobertura natural, compuesta principalmente por la cobertura forestal y tacotales. Encontramos que la cobertura natural más abundante para ambas áreas protegidas fue cubierta forestal en todos los años estudiados. La estabilidad y las grandes áreas de la cubierta forestal en LCNP y RMWR para 2005 y 2010 reflejan que las políticas, las acciones de manejo y vigilancia tienen un impacto positivo en la conservación y restauración de los hábitats naturales en esta zona del Pacifico Central Costarricense. Sin embargo, la alta complejidad del paisaje de SA en 1997, 2005 y 2010 son una prueba de presión antropogénica sobre estas áreas protegidas y sugieren una ineficacia de los gobiernos locales para monitorear y disminuir los cambios de uso del suelo que podrían obstaculizar la gestión, conservación y restauración de especies dentro de las áreas protegidas.

    Full Text Available Abstract The authors analyse biological characteristics of the fox Vulpes vulpes with regard to the epidemiology of sylvatic rabies in Italy. Emphasis is put on the lack of deepen studies both on fox population densities, and on important behavioural habits. A retrospective analysis of wild rabies epidemics in Italy from 1977 to 1988 has shown: 1 the spread of rabies by 20 to 80 km/year; 2 the existence of three/four year oscillations, clearly evident in single epidemics, but masked in the total number of cases in Italy; 3 the mosaic-like pattern of the final phase of the epidemic; 4 the extinction of outbreaks following the mosaic phase, in a few cases not correlated with human intervention. The authors criticize the control measures enforced in Italy, on the bases of the inefficacy and inefficiency of the thinning out programme and, on the contrary, the efficiency of the oral vaccination of the fox population. Riassunto Gli autori analizzano la biologia della Volpe (Vulpes vulpes in relazione all'epidemiologia della rabbia silvestre in Italia; sottolineano la grave carenza di dati nel nostro Paese sia sulla densità di popolazione della Volpe, sia su aspetti di ecologia comportamentale importanti per l'epidemiologia della rabbia silvestre in Italia dal 1977 al 1988 rilevando: 1 una velocità di avanzamento variabile da 20 a 80 km/anno; 2 una ciclicità tri-quadriennale per singola epidemia che può essere mascherata se si considera erroneamente la sommatoria dei casi accertati; 3 l'andamento a mosaico delle fasi finali delle epidemie; 4 l'estinzione dei focolai successivamente alla fase a mosaico, in alcuni casi non correlabile all'intervento dell'uomo. Infine, gli autori analizzano in modo critico la profilassi della rabbia nella Volpe attuata in Italia, rilevando la scarsa efficacia ed inefficienza dello sfoltimento e, in contrapposizione, l'efficacia e l'economicità della vaccinazione

Foram analisados registros constantes dos Autos de Infração Ambiental lavrados pelos órgãos de fiscalização ambiental (Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais Renováveis, Secretaria de Estado do Meio Ambiente, Instituto de Meio Ambiente e Ordenamento Territorial do Amapá e Batalhão de Polícia Militar Ambiental no período de 2005 a 2009. Os resultados mostraram que foram apreendidos 1.986 animais silvestres que geraram R$ 694.937,00 em multas. As apreensões ocorreram em 13 dos 16 municípios amapaenses, com destaque para Macapá e Santana que concentraram 87% das autuações. As infrações mais cometidas foram a posse ou manutenção de animais em cativeiro e o transporte de carne e de animais vivos com 38,14% e 30,77%, respectivamente. Répteis e aves foram os mais apreendidos com 48% e 45%, enquanto os mamíferos foram os menos apreendidos com 7% das apreensões. Do total de espécimes apreendidos, 736 pertencem a nove espécies constantes da lista de espécies ameaçadas, das quais, sete constam simultaneamente nas listas da IUCN e da CITES. Concluiu-se que a fauna silvestre tem sido utilizada de forma indiscriminada para fins de criação e consumo alimentar nas áreas rurais e urbanas do Estado e, que deficiências na execução das atividades de fiscalização dificultam a coibição dessa atividade ilícita.

    2011-01-01

    Full Text Available Aún persisten importantes interrogantes sobre los centros de origen y mecanismos de dispersión de la Tuberculosis (TB a lo largo del poblamiento de las diversas regiones del mundo. Estudios moleculares e inmunológicos de lesiones óseas en momias de los Andes Meridionales indican que la TB estaba presente en América del Sur antes de la llegada de los europeos. Este trabajo, enmarcado en un proyecto más amplio de paleopatología, tiene como objetivo plantear nuevas hipótesis sobre las fuentes de contagio de TB en grupos de cazadores recolectores del extremo austral de Sudamérica. Hace dos décadas se diagnosticó por primera vez TB en diversas especies de pinnípedos otáridos de Australia y Argentina. En el año 2003 estudios moleculares determinaron que esta TB estaba causada por una nueva especie descripta como Mycobacterium pinnipedii, siendo entonces el último miembro del Mycobacterium tuberculosis complex (MTC. Esta nueva especie es responsable de producir TB en humanos y también en animales silvestres y domésticos. La recuperación en contextos arqueológicos de Tierra del Fuego de restos humanos con lesiones óseas de TB (confirmado por análisis moleculares, fechados 640±20 BP, incorpora un nuevo escenario sobre las fuentes de contagio de esta enfermedad en el Hemisferio Sur. La distribución y movilidad tanto de cazadores-recolectores como de sus presas es analizada a partir de información etnográfica y ecológica, paralelamente se plantea considerar también a los camélidos sudamericanos como posibles trasmisores de TB. Futuros estudios arqueológicos y arqueofaunísticos basados en el mejoramiento de técnicas genéticas moleculares, serán fundamentales para un paleodiagnóstico de TB más preciso.

    Full Text Available La memoria espacial se considera un factor selectivo en la evolución de la inteligencia. Los estudios en animales permiten pensar que los procesos cognitivos descriptos en humanos comparten características con los de otras especies. Se estudió el comportamiento espacial vinculado a la búsqueda del alimento de los monos capuchinos y su capacidad de retener información sobre la ubicación y estado del mismo. Durante los seguimientos de tres grupos de Cebus nigritus silvestres se aplicó un diseño observacional cualitativo que evaluó las cantidades de fruta madura e inmadura presentes en los árboles frutales consumidos por los monos en sus desplazamientos diarios. Las visitas a los árboles de frutos indicaron que los monos retienen información particular sobre la ubicación y condición de cada árbol. Los resultados obtenidos son fundamentales para la comprensión del funcionamiento de los mecanismos cognitivos no mediados por el lenguaje, lo cual permite ampliar los conocimientos de la base biológica del comportamiento espacial no humano. Palabras clave: Cebus=Sapajus nigritus; árboles frutales; velocidad de acercamiento; visita Spatial memory is considered a selective factor in the evolution of intelligence. Animal studies lead us to believe that cognitive processes described in humans may have much in common with those of other species. We studied the foraging spatial behavior of capuchin monkeys and their ability to retain information about food location and quality. We analyzed whether individuals were able to integrate stored information about food sites and changes in the ripening of the resource. A qualitative observational design was used to monitor three groups of wild Cebus nigritus in their daily movements, evaluating the amounts of ripe and unripe fruit present in the fruiting trees consumed by monkeys. Visits to fruiting trees showed that monkeys remember specific information on the location and condition of each tree

    This study investigated whether individual behavioural characteristics of piglets and stress induced by experience with humans can influence learning performance. After weaning, piglets received a chronic experience with humans to modulate their emotional state: rough (ROU), gentle (GEN), or minimal (MIN) experience. Simultaneously, they were trained on a discrimination task. Afterward, their behaviour during challenge tests was assessed. The first learning step of the task involved associating a positive sound cue with a response (approach a trough) and success of piglets depended mostly on motivation to seek for reward. Although the experience with humans did not have direct effect, the degree of fear of handler, measured based on their reactivity to a human approach test, was related to motivation to seek rewards and learning speed of this first step in stressed ROU piglets, but not in MIN and GEN piglets. In contrast, the second learning step was more cognitively challenging, since it involved discrimination learning, including negative cues during which piglets had to learn to avoid the trough. Locomotion activity, measured during an open-field test, was associated with performance of the discrimination learning. To conclude, fearfulness towards humans and locomotion activity are linked with learning performance in relation to task complexity, highlighting the necessity to take into account these factors in animal research and management.

    Full Text Available The faunal assemblage from the 9(th-8(th millennium BP site at Sha'ar Hagolan, Israel, is used to study human interaction with wild suids and cattle in a time period just before the appearance of domesticated animals of these species in the Jordan Valley. Our results, based on demographic and osteometric data, indicate that full domestication of both cattle and suids occurred at the site during the 8(th millennium. Importantly, domestication was preceded in both taxa by demographic and metric population parameters indicating severe overhunting. The possible role of overhunting in shaping the characteristics of domesticated animals and the social infrastructure to ownership of herds is then explored.

    2007-06-01

    This study aimed to investigate whether feed restriction and re-alimentation differently affect lipid content and activities of lipogenic or catabolic enzymes according to muscle types in pigs. At around 28 kg body mass (BW), sixty pigs (n=30 per group) were allocated to either ad libitum (AL) or restricted/re-feeding (RA) regimens. After feed restriction (80 kg BW), lipid content was reduced (P<0.01) in the oxidative rhomboideus (RH) as in the glycolytic biceps femoris (BF) muscles of RA pigs compared with AL pigs. Lower activities (P<0.05) of the lipogenic enzymes fatty acid synthase (FAS) and malic enzyme (ME) were observed in the RH but not in the BF of RA vs. AL pigs. After re-feeding (110 kg BW), lipid content was restored in the RH, but was still 12% lower (P<0.05) in the BF of RA compared with AL pigs. In the RH, the trend for an enhanced FAS activity and for a smaller weight-related decrease of ME activity in RA pigs than AL pigs during re-feeding, may have contributed to the muscle fat recovery observed in the RA pigs. In the BF, higher oxidative enzyme activities (P<0.10) in RA pigs compared to AL pigs might explain the incomplete lipid recovery observed after re-feeding in the former animals. In conclusion, metabolic activities in response to restriction and re-feeding differed according to muscle metabolic type.

    Rhodococcus equi is now considered an emerging zoonotic pathogen. Sources and routes of human infection remain unclear but foodborne transmission seems to be the most probable way. Strains of pig or bovine type are most often isolated from human cases and moreover R. equi is present in submaxillary lymph nodes of apparently healthy pigs and wild boars intended for human consumption. The aim of this study was to estimate the prevalence of R. equi in submaxillary lymph nodes in wild boars, roe deer and red deer. Samples were collected from 936 animals and 27 R. equi strains were isolated, from 5.1 % of wild boars (23/452), 0.7 % of red deer (2/272) and 0.9 % of roe deer (2/212). Genetic diversity of all 27 isolates was studied using VspI-PFGE method, resulting in the detection of 25 PFGE patterns and four PFGE clusters. PFGE patterns of the isolates were compared with virulence plasmid types and no concordance was observed. R. equi was present in wild animal tissues and consumption of the game may be a potential source of R. equi infection for humans. To the authors' best knowledge, this is the first epidemiological report of R. equi prevalence in tissues of roe deer and red deer. However, risk associated with wild ruminant consumption seems marginal. Investigation of R. equi transmission between animals and humans based exclusively on types of virulence plasmids seems to be insufficient to identify sources of R. equi infection for people.

    The vocal expression of emotion is likely driven by shared physiological principles among species. However, which acoustic features promote decoding of emotional state and how the decoding is affected by their listener's psychology remain poorly understood. Here we tested how acoustic features of piglet vocalizations interact with psychological profiles of human listeners to affect judgments of emotional content of heterospecific vocalizations. We played back 48 piglet call sequences recorded in four different contexts (castration, isolation, reunion, nursing) to 60 listeners. Listeners judged the emotional intensity and valence of the recordings and were further asked to attribute a context of emission from four proposed contexts. Furthermore, listeners completed a series of questionnaires assessing their personality (NEO-FFI personality inventory), empathy [Interpersonal Reactivity Index (IRI)] and attitudes to animals (Animal Attitudes Scale). None of the listeners' psychological traits affected the judgments. On the contrary, acoustic properties of recordings had a substantial effect on ratings. Recordings were rated as more intense with increasing pitch (mean fundamental frequency) and increasing proportion of vocalized sound within each stimulus recording and more negative with increasing pitch and increasing duration of the calls within the recording. More complex acoustic properties (jitter, harmonic-to-noise ratio, and presence of subharmonics) did not seem to affect the judgments. The probability of correct context recognition correlated positively with the assessed emotion intensity for castration and reunion calls, and negatively for nursing calls. In conclusion, listeners judged emotions from pig calls using simple acoustic properties and the perceived emotional intensity might guide the identification of the context.

  10. The Influence of Antral Ulcers on Intramural Gastric Nerve Projections Supplying the Pyloric Sphincter in the Pig (Sus scrofa domestica-Neuronal Tracing Studies.

    Directory of Open Access Journals (Sweden)

    Michal Zalecki

    Full Text Available Gastric ulcerations in the region of antrum pylori represent a serious medical problem in humans and animals. Such localization of ulcers can influence the intrinsic descending nerve supply to the pyloric sphincter. The pyloric function is precisely regulated by intrinsic and extrinsic nerves. Impaired neural regulation could result in pyloric sphincter dysfunction and gastric emptying malfunction. The aim of the study was to determine the effect of gastric antral ulcerations on the density and distribution of intramural gastric descending neurons supplying the pyloric sphincter in pigs.The experiment was performed on 2 groups of pigs: healthy gilts (n=6 and gilts with experimentally induced peptic ulcers in the region of antrum pylori (n=6. Gastric neurons supplying pyloric sphincter were labeled using the retrograde neuronal tracing technique (20μl of Fast Blue tracer injected into the pyloric sphincter muscle. After a week survival period the animals were sacrificed and the stomachs were collected. Then, the stomach wall was cross-cut into 0.5cm thick sections taken in specified intervals (section I - 1.5cm; section II - 3.5cm; section III - 5.5cm; section IV - 7.5cm starting from the sphincter. Consecutive microscopic slices prepared from each section were analyzed under fluorescent microscope to count traced neurons. Obtained data were statistically analyzed. The total number of FB-positive perikarya observed within all studied sections significantly decreased from 903.3 ± 130.7 in control to 243.8 ± 67.3 in experimental animals. In healthy pigs 76.1 ± 6.7% of labeled neurons were observed within the section I, 23.53 ± 6.5% in section II and only occasional cells in section III. In experimental animals, as many as 93.8 ± 2.1% of labeled cells were observed within the section I and only 6.2 ± 2.2% in section II, while section III was devoid of such neurons. There were no traced perikarya in section IV observed in both groups of pigs.Obtained results revealed for the first time significant impact of antral ulcerations on intramural descending nerve pathways supplying the pyloric sphincter in pigs, animals of increasing value in biomedical research and great economic importance.

    We sought to compare the flow rates of the proximal tibia, the distal femur, and the proximal humerus using high pressure (greater than 300 mmHg) through an intraosseous (IO) infusion needle in an adult swine model. We performed a prospective interventional study in 11 swine. After placement of central vein and arterial lines, blood was removed via the central line until the animal's mean arterial pressure decreased 25% from the recorded baseline. We inserted a 25-mm IO needle into the proximal tibia and 45-mm needles into the distal femur and proximal humerus. All extremities were utilized in each study animal. We infused normal saline at each site for 10 minutes with a pressure bag inflated to the highest achievable pressure (greater than 300 mmHg) as measured at the infusion site with a calibrated portable inline pressure gauge. We measured the volume of normal saline remaining and we calculated infusion rates for each site. We then compared infusion flow rates between the three locations. Statistical analysis and comparison of the infusion rates of all three study arms were as performed using analysis of variance (ANOVA). The average weight of the swine was 71 kg (range 64-84 kg). Successful placement of the IO needle was confirmed at all three sites. The mean infusion flow rate was 213 mL/min (standard deviation [SD] 53.2 mL/min) for the proximal humerus, 138 mL/min (SD 65.3 mL/min) for the distal femur, and 103 mL/min (SD 48.1 mL/min) for the proximal tibia (p IO placement, with a potential for higher flow rates than the proximal tibia and distal femur when resuscitating a patient.

  18. Origin and distribution of the sciatic nerve in pig fetuses (Sus scrofa domesticus – Linnaeus, 1758 from the lineage Pen Ar Lan

    Full Text Available The origin and distribution of the sciatic nerve was studied in 31 pig fetuses from the lineage Pen Ar Lan, being 22 males and 9 females, after being fixed in a 10% formaldehyde aqueous solution. In these animals, the lumbar vertebrae ranged from 5 to 7, with a predominance of 6, something which contributed to variations in the origin of this nerve. The sciatic nerve originated in 80.64% of the antimeres from the ventral branch of the fifth lumbar spinal nerve (L5; in 96.77 % of L6; in 6.45% of L7; in 100% of S1; and in 64.51% of S2. The composition of this nerve took place in 45.16% of the animals due to the union of L5, L6, S1 and S2; in 32.25% of L5, L6 and S1; in 12.90% of L6, S1 and S2; in 6.45% of L6, L7 and S1; and in 3.22% L5, S1 and S2. There was symmetry in the origin of the sciatic nerve in all specimens under study. This nerve sent branches to the superficial gluteal, semitendinosus, semimembranosus and biceps femoris muscles in all specimens, and, in a lesser frequency, to the twins, quadratus femoris, adductors, as well as the middle, accessory, and deep gluteal muscles. In 74.19% of the sample, a branch communicating to the pudendal nerve was observed.

    The feral swine (FS) originated from the domestic pig and is present throughout the Brazilian wetland plain (the Pantanal). Aujeszky's disease (AD) was first serologically confirmed in the state of Mato Grosso do Sul (MS) in 2001; however, there was no viral confirmation. The aim of this study was to investigate antibodies against-SuHV-1 in the sera of feral swine in the studied areas, detect SuHV-1 through PCR and classify the viral genome. Among the 218 animals sampled, 186 were analyzed by ELISA, resulting in 88 (47.3%) reactive samples. In the serum neutralization test (SN), 57/179 (31.8%) samples presented antibodies against the AD virus (SuHV-1). By nested PCR, 104 DNA samples were extracted for analysis and confirmed with amplification of a fragment of glycoprotein B (gB) in five samples. The SuHV-1 was detected in 12 samples by using primers for glycoprotein E (gE) and viral genome was classified as Type I by ul44 partial sequencing. The amplification of SuHV-1 glycoprotein fragments in the fetuses of seropositive sows indicate that the vertical transmission contribute to maintain SuHV-1 in a free-living feral swine population. The origin of AD in the feral swine populations of the Pantanal is unknown, however, the determination of viral latency, the vertical transmission of the antigen by the amplification of SuHV-1 glycoprotein fragments in the fetuses of seropositive sows and genome typing contribute to the elucidation of the epidemiology of this disease in the wetlands of MS, Brazil.

    Full Text Available O maracujazeiro-azedo é acometido por diversas doenças, sendo que as do sistema radicular tendem a inviabilizar o cultivo em diversas regiões; entretanto, há espécies de Passifloras que se demonstram resistentes, sendo que tornam necessários estudos sobre a influência pela enxertia destas espécies no maracujazeiro-azedo. Portanto, objetivou-se estudar a viabilidade da enxertia e o desenvolvimento inicial de maracujazeiro-azedo (Passiflora edulis enxertado sobre P. alata, P. cincinnata, P. edulis, P. gibertii, P. morifolia e P. mucronata, comparadas com P. edulis não enxertado, proveniente de sementes. Aos 60 dias após a semeadura, foi realizada a enxertia por garfagem e, por um período de 105 dias, avaliaram-se a sobrevivência dos enxertos, altura da planta, comprimento dos internódios, número de folhas, diâmetro do porta-enxerto e do enxerto, área foliar e a massa da matéria seca da parte aérea e das raízes. A sobrevivência da enxertia foi superior a 90%, exceto na combinação P. edulis/P. morifolia que não apresentou brotações do enxerto e, posteriormente, morreram. A combinação P. edulis/P. gibertii tiveram menor altura do que P. edulis/P. mucronata, porém com semelhantenúmero de folhas, demonstrando que o P. gibertii teve efeito ananizante, devido à redução do comprimento dos internódios. O maior diâmetro do enxerto foi apresentado por P. edulis/P. edulis, indicando maior compatibilidade de enxertia dentro da mesma espécie. Dentre as espécies silvestres utilizadas como porta-enxerto, P. mucronata proporcionou maior desenvolvimento da parte aérea.

  7. Are camouflaged seeds less attacked by wild birds? Sementes camufladas são menos atacadas por aves silvestres?

    Directory of Open Access Journals (Sweden)

    Alexandre de Almeida

    2010-04-01

    Full Text Available Wheat, corn and rice crops in Brazil use seeds treated with systemic insecticide/nematicide carbofuran, mixed to rhodamine B red dye. Carbofuran is toxic and rhodamine B is attractive to wild birds that eat up these seeds, resulting in notable mortality during planting. A field experiment was performed in southeast Brazil to evaluate if camouflaged seeds would be less consumed by wild birds in comparison to commercial seeds with red-colored rhodamine B and aposematic blue seeds. Camouflaged seeds were less removed than seeds with rhodamine B and natural colors. The camouflaging was more effective in the presence of irregularities and litter. There was no removal of blue-colored seeds. As legislation requires treated seeds to receive a different color to avoid accidents with humans, camouflaging may be used as replacement of rhodamine B to reduce mortality rates of wild birds.Plantações de trigo milho e arroz no Brasil utilizam sementes tratadas com o inseticida e nematicida sistêmico carbofuran, associado ao corante vermelho rodamina B. O carbofuran é tóxico e a rodamina B é atrativa às aves silvestres, as quais consomem estas sementes, resultando em notável mortalidade durante o plantio. Um experimento realizado em campo agrícola no sudeste do Brasil mostrou que sementes camufladas foram menos removidas por aves silvestres do que sementes com rodamina B. A camuflagem foi potencializada em presença de irregularidades e serrapilheira no solo. Não houve remoção de sementes de cor azul, mas a formulação granular de cor azul tem causado mortalidade de aves nos USA e Canadá. Como sementes tratadas com agrotóxicos devem, de acordo com a legislação, receber coloração diferenciada para evitar acidentes com humanos, a camuflagem pode ser utilizada, substituindo a rodamina B.

    Full Text Available El Caribe costarricense es importante como sitio de alimentación, copulación, anidación y desove de las tortugas marinas, por lo que el presente trabajo pretendió actualizar el patrón de anidación en las tortugas marinas Dermochelys coriacea y Eretmochelys imbricata en el sector Gandoca, del Refugio Nacional de Vida Silvestre Gandoca Manzanillo, Limón, Costa Rica, para proponer medidas de manejo. Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011, y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525. Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

    Full Text Available A partir de una reseña sobre el papel del intervencionismo estatal en la conducción de la economía y de la pugna con el neoliberalismo, se hace una revisión de los modelos económicos aplicados a lo largo del siglo y se muestran sus rasgos principales, sus problemas y sus paradojas. A partir de alfí, se examina lo sucedido en América Latina, para dar cuenta de las particularidades del caso colombiano, cuyo modelo en esta década muestra una distancia grande del modelo neoliberal, mientras sus problemas lo acercan a los dilemas y sin salidas del intervencionismo, en un contexto que requeriría otras fórmulas para hacer posible la paz. Frente a ello, se examinan las posiciones y propuestas de los economistas, vistas bajo la aguda polarización entre intervencionismo y neoliberalismo, pero en circunstancias críticas que alejan los logros en torno a la modernización, la estabilidad de precios, la sólida fundamentación macroeconómica y la democratización política.

    Full Text Available This report concerns an outbreak of postweaning multisystemic wasting syndrome in wild boars from commercial herds in Rio Grande do Sul, Brazil. The main clinical signs were progressive wasting, respiratory distress, diarrhea, and ocular discharges. Enhanced lymph nodes and spleens, ascites, hydrothorax, and non collapsed lungs were the principal gross lesions. Varying degrees of lymphohistiocytic infiltrates in lymph nodes, spleen, and intestines were the most significant microscopic changes. Although a total of 26 animals had showed clinical and pathological findings consistent with the disease, only in 11 of them it was possible to confirm a PMWS diagnosis through the association of specific lesions in lymphoid tissues with the presence of the viral antigen detected by immunohistochemistry. These findings were similar to those reported in the swine disease.Descreve-se a ocorrência da síndrome multissistêmica do definhamento suíno em javalis de dois rebanhos comerciais no estado do Rio Grande do Sul. Os principais sinais observados foram definhamento progressivo, tosse, espirros, diarréia e descarga ocular. Linfonodos e baços aumentados, ascite, hidrotórax e pulmões não colapsados foram os principais achados macroscópicos. Infiltrados linfo-histiocitários de graus variáveis em linfonodos, baços e intestinos foram as lesões microscópicas mais relevantes. Embora 26 animais tenham apresentado achados clínicos e patológicos compatíveis com a enfermidade, apenas em 11 desses foi possível confirmar o diagnóstico através da associação de lesões histológicas específicas nos tecidos linfóides com a presença do antígeno viral, detectado pela técnica de imunoistoquímica. Tanto os achados clínicos como patológicos foram semelhantes aos descritos na doença suína.

    Full Text Available Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in southeastern Brazil. It also raises the hypothesis of possible applications of Hymenoptera to achieve more precise PMI estimations, apart from other insects already known as having great importance in such estimates.Considerável importância tem sido dada às construções de ninhos e transporte de alimento larval para o ninho como uma pré-condição para a eusociabilidade dos insetos. Muitos adultos de himenópteros alimentam-se em líquidos, embora as abelhas e poucas vespas podem também se alimentarem de pólen. Carcaças representam uma fonte adicional de proteína para algumas espécies e elas foram uma vez observadas se alimentando de animais mortos na natureza. Este trabalho tem por objetivo analisar Hymenoptera visitantes em carcaças de porcos durante o verão de 2005 e inverno de 2006 no Brasil, ao longo dos estágios de decomposição, comparando com resultados de outros estudos na região Neotropical. Pelo nosso conhecimento, esse é o primeiro estudo que descreveu a ocorrência de Agelaia pallipes, Polybia paulista e Scaptotrigona depilis em carcaças em decomposição no sudeste do Brasil. Isso também aumenta a hipótese na possibilidade de aplicação de Hymenoptera em auxiliar a estimar o IPM de maneira mais precisa, sem levar em conta insetos que já possuem grande importância forense.

    Conclusión. Los métodos semicuantitativos de priorización son una fuente de información para la toma de decisiones, pero su utilización es poco frecuente en los países en desarrollo por la falta de datos de vigilancia en salud pública. El control de las enfermedades que afectan tanto a los seres humanos como a los animales silvestres, requiere el desarrollo de estrategias que reduzcan la transmisión de patógenos de estos a los animales domésticos y a los seres humanos.

  4. Behavioral experiments in a wild passerine cause short-term reductions in parental provisioning and nestling mass Experimentos conductuales en un ave paserina silvestre causan reducciones de corto plazo en el cuidado parental y peso de pichones

    Full Text Available Research on wild animals often involves the capture and temporary removal of individuals from their territory. Although the acute effects of such procedures are well understood in terms of stress hormone profiles, their effect on the behaviour of captured individuals after release is poorly known. Additionally, for socially-monogamous individuals captured whilst breeding, little is known regarding whether the remaining individual compensates for the temporary loss of its partner and whether offspring condition or survival ultimately decreases due to any reductions in parental provisioning. We investigated the influence of field-based experiments requiring temporary adult removal on adult provisioning behaviour and nestling mass in the thorn-tailed rayadito (Aphrastura spinicauda, a Chilean furnariid species with equal parental effort between sexes. During the absence of the removed individual, remaining individuals did not increase nestling provisioning rates while, upon their release, removed individuals did not return to nestling feeding for at least 38 minutes and typically much longer. This drastic reduction in combined parental provisioning negatively affected nestling mass, while average nestling mass increased during a control period, nestlings failed to gain weight during and subsequent to parental removal. Finally, our experiments did not affect fledging probability. Overall, our results indicate that the temporary removal of rayaditos from their territories can cause short-term reductions in parental provisioning and nestling weight, but is unlikely to lead to any long-term effects on nestling survival.Las investigaciones en animales silvestres frecuentemente requieren la captura y remoción de individuos de sus territorios. Si bien se conocen los efectos a nivel hormonal de tales métodos, sus efectos sobre la conducta de los individuos después de la liberación son escasamente conocidos. Además, para individuos de especies mon

    Full Text Available Se hace una revisión sobre el origen de la concepción de vida silvestre, rastreando su significado desde el siglo XIV hasta el presente. Aunque existen en Inglaterra referencias muy antiguas sobre la concepción de vida silvestre, es en Estados Unidos donde nace y evoluciona dicho término. Al comparar las concepciones de la vida silvestre en los Estados Unidos respecto a los países latinoamericanos, se evidencia la enorme importancia cultural, educativa, política y social dada a tales concepciones en el continente norteamericano en contraste con Latinoamérica, particularmente Colombia, en donde no se dan tales manifestaciones. Igualmente, la historia de la educación e investigación en educación sobre la vida silvestre en los Estados Unidos revela una notoria inserción de esta temática tanto en los textos divulgativos (educación no formal como en la literatura científica y en los currículos de educación básica y universitaria. En dicho país es posible conjeturar un cambio evolutivo en la concepción de vida silvestre que, de acuerdo con nuestra investigación, se inicia a finales del siglo XIX con un significado de fauna de caza deportiva y culmina, hacia la década de 1970 con la inclusión de todos los reinos de la naturaleza así como su hábitat e interrelaciones. En nuestro país, y en general para Suramérica, es muy escasa la literatura especializada sobre vida silvestre, no existiendo facultades o carreras con dicha temática a pesar de la enorme biodiversidad de este continente. Algunas de las razones aducidas por el autor, que explican esta situación, son la influencia de la visión taxonómica de la naturaleza, privilegiada en Colombia por la Expedición Botánica, y la dificultad para incorporar la educación ambiental en el contexto académico universitario. Se concluye igualmente la escasa investigación en vida silvestre y el potencial que existe para desarrollarla en el campo de las ciencias naturales y sociales

  7. First Ecological Study of the Bawean Warty Pig (Sus blouchi, One of the Rarest Pigs on Earth.

    Mark Rademaker

    Full Text Available The Bawean warty pig (Sus blouchi is an endemic pig species confined to the 192 km(2 large island of Bawean in the Java Sea, Indonesia. Due to a lack of quantitative ecological research, understanding of natural history and conservation requirements have so far been based solely on anecdotal information from interviews with local people and study of captive and museum specimens. In this study we provide the first assessment of population and habitat preferences for S. blouchi by using camera trapping. From the 4th of November 2014 to January 8th 2015, we placed camera traps at 100 locations in the forested protected areas on Bawean. In 690.31 camera days (16567.45 hours we captured 92 independent videos showing S. blouchi. Variation in S. blouchi trapping rates with cumulative trap effort stabilized after 500 camera days. An important outcome is that, in contrast to the suggestion of previous assessments, only S. blouchi was detected and no S. scrofa was found, which excludes hybridization threats. We fitted a Random Encounter Model, which does not require the identification of individual animals, to our camera-trapping data and estimated 172-377 individuals to be present on the island. Activity patterns and habitat data indicate that S. blouchi is mainly nocturnal and prefers community forests and areas near forest borders. Next to this, we found a positive relationship between S. blouchi occupancy, distance to nearest border, litter depth and tree density in the highest ranking occupancy models. Although these relationships proved non-significant based on model averaging, their presence in the top ranking models suggests that these covariables do play a role in predicting S. blouchi occurrence on Bawean. The estimated amount of sites occupied reached 58%. Based on our results, especially the estimation of the population size and area of occupancy, we determine that the species is Endangered according to the IUCN/SSC Red List criteria.

    Full Text Available The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and São Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus and scaly-headed parrots (Pionus maximiliani. Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira. Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus. It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments.O objetivo deste trabalho foi pesquisar a frequência de ocorrência e a variedade de parasitas intestinais de animais silvestres de vida livre.

    Full Text Available El daño causado por fauna silvestre en cultivos agrícolas es una de las causas principales de conflicto dentro y fuera de áreas protegidas. Para un adecuado manejo del conflicto se requieren evaluaciones del daño y de la aplicación de distintos métodos de mitigación. El objetivo del trabajo fue evaluar la efectividad de prácticas agroculturales y cacería de control, para reducir daños por vertebrados silvestres en cultivos agrícolas anuales en el PN ANMI Cotapata. Se trabajó en siete parcelas con prácticas agroculturales, cuatro parcelas con cacería de control y cinco parcelas control, registrándose el tipo y densidad de cultivo, frecuencia de visitas de especies dañinas a huelleros, plantación perdida, especies responsables y biomasa de cosecha. Los resultados muestran que las especies más frecuentes fueron: Dasyprocta sp. y Dasypus novemcinctus, siendo estas 1.6 veces más frecuentes en parcelas con prácticas agroculturales. En promedio se perdió 7.3% de la plantación en parcelas agroculturales, 4.6% en parcelas sujetas a cacería de control, y 27.6% en parcelas control. Las principales especies responsables de las pérdidas fueron: P. tajacu, seguido por Dasyprocta sp. y S. apella. A través de estas estrategias de manejo, redujo las pérdidas en >50%, con lo cual se considera que los métodos puestos a prueba son útiles y se recomienda utilizarlos a gran escala con la consideración de que podría ser necesario innovar cada cierto tiempo, pues los animales silvestres tienden a acostumbrarse a los métodos de ahuyentamiento en ejecución.

    Laminated composites are of great interest in different industries while having the advantages of all base metals. In this research, the laser bending of a three-layered SUS430/C11000/SUS430 laminated composite is characterized both experimentally and numerically. This composite can be used in the microelectronics industry since it has the anti-corrosion and strength capability of stainless steel, and the electrical superiority of copper. The specimens are bent using a Ytterbium fiber laser irradiated on a straight path along the sheet width. The effects of bending parameters including the number of passes, scanning velocity, beam diameter, laser power and delay time between passes are examined for a three-layered laminated sheet, and compared with its constituent steel and copper layers. It is found that the thin copper mid-layer strongly affects the rate of bending per pass. Heat distribution and plastic strain along the thickness during the process are characterized by using the finite element method. The Cu mid-layer decreases the bending angle, but also postpones the onset of melting, and thus can be compensated by the application of higher laser powers. It is shown that the bending angle increases with an increase in laser power and delay time, and a decrease in laser velocity and beam diameter.

    Full Text Available Anualmente o tráfico de animais silvestres retira milhões de aves da natureza. Os cardeais (Paroaria coronata e cardeais-do-nordeste (Paroaria dominicana estão incluídos entre as espécies de aves mais traficadas. A microbiota cloacal de passeriformes de vida livre é composta principalmente por bacilos e cocos gram-positivos, já os bacilos gram-negativos predominam em aves de cativeiro. Em situações de estresse e baixa de imunidade as bactérias gram-negativas podem causar infecções oportunistas. O presente trabalho identificou bactérias da microbiota da cloaca de 49 espécimes de P. coronata e P. dominicana apreendidas do tráfico de animais silvestres em São Paulo (SP. Foram isoladas treze espécies de bactérias gram-negativas, incluindo Salmonella spp. e Pseudomonas aeruginosa. A maior frequência de ocorrência foi de Escherichia coli, identificada em 42/49 (85,7% das amostras fecais. Dentre os isolados de E. coli, 21/42 pertenciam aos grupos filogenéticos B2 e D, relacionados a estirpes patogênicas que causam doença extraintestinal em humanos. Klebsiella pneumoniae foi isolada em 28/49 (57,1% das amostras. Esses resultados reforçam que as condições estressantes a que esses animais são submetidos em situações de tráfico, incluindo o contato com humanos, podem favorecer a colonização da microbiota cloacal das aves por patógenos, o que representa um risco para a sua reintrodução na natureza considerando-se o possível contato com humanos e outros animais.

    Full Text Available La destrucción del hábitat conlleva a la fragmentación de poblaciones de especies silvestres y se considera como uno de los principales factores en la extinción de especies A medida que las poblaciones se vuelven más pequeñas, surgen amenazas hacia su estabilidad y persistencia, como resultado de factores estocásticos demográficos, ambientales y genéticos. El objetivo de este trabajo fue estudiar los efectos de la fragmentación de poblaciones en la viabilidad de Alouatta palliata y Cebus capucinus en el Refugio de Vida Silvestre Privado Nogal (RVSPN, Sarapiquí, Heredia. Para esto se uso el programa VORTEX para correr un análisis de viabilidad de poblaciones (PVA para ambas especies. La información utilizada en el PVA proviene de la estructura demográafica de las poblaciones del RVSPN, literatura sobre la historia natural de las especies y artículos relacionados con PVA. Los resultados sugieren que tanto A. palliata como C. capucinus pueden sobrevivir en fragmentos boscosos aislados. Sin embargo, si se incorporan factores como depresión por endogamia, catástrofes o perdida de hábitat, las pequeñas poblaciones fragmentadas se vuelven inestables y aumenta el riesgo de que desaparezcan. Las poblaciones continuas fueron más robustas ante las amenazas incorporadas, por lo que se recomienda continuar con la reforestación para unir los fragmentos boscosos. Es importante darle seguimiento a las poblaciones de ambas especies y tener un manejo de su hábitat para disminuir los efectos negativos de diferentes eventos estocásticos provocados por el ambiente.

    A. F. MAZON

    Full Text Available Hematological and physiological changes in the blood of juveniles of the freshwater fish, Prochilodus scrofa were determined after acute exposure to 20, 25, and 29 mugCu L-1 in water (pH 7.5; hardness 24.5 mg L-1 as CaCO3 for 96 h. Copper exposure to 25 and 29 mugCu L-1 caused significant increase in the hematocrit and red blood cell values. The increase in red blood cells was associated with increase in whole blood hemoglobin only in fish exposed to 29 mugCu L-1. Leukocytes increased following copper exposure and were significantly higher in fish exposed to 29 mugCu L-1. Differential leukocyte percentage displayed significant reduction in lymphocytes and an increase in neutrophils in fish exposed to 25 and 29 mugCu L-1. The percentage of monocytes remained unchanged after copper exposure. The thrombocytes did not change. There was a significant decrease in plasma [Na+] and [Cl-] and a significant drop in blood pH in fish exposed to 25 and 29 mugCu L-1 while [K+] showed significant increase in fish exposed to 29 mugCu L-1. Copper exposure led to ionoregulatory impairment, although chloride cell hypertrophy was induced. The changes in red blood cells suggest a compensatory response to respiratory surface reduction of gills (tissue damage and cell proliferation in order to maintain oxygen transference from water to the tissues, allowing the fish to survive during the so-called shock phase of LC50 exposure, at least while at rest.

    When venison with embedded copper bullets was subjected to different culinary processing procedures, the amount of copper released from the embedded bullet was affected more by the retention period of the bullet in the meat during cool storage, than by the different heating protocols. The presence of copper fragments had no significant effect on levels of thiobarbituric acid reactive substances (TBARS). Conversely, TBARS in lean meat (fallow deer, wild boar, roe deer) were significantly affected by culinary treatment (higher TBARS in boiled and boiled-stored meat than in meat barbecued or boiled in brine). In pork-beef patties doped with up to 28mg/kg Cu, TBARS increased after dry-heating and subsequently storing the meat patties. The amount of copper doping had no effect on TBARS for 0 and 7days of storage, but a significant effect at day 14 (fat oxidation retarded at higher Cu doses). Evidence is presented that wild boar meat may be more sensitive to fat oxidation than pork-beef. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Acute respiratory distress syndrome (ARDS is a fatal complication of severe sepsis. Due to its higher molecular weight, the use of colloids in fluid resuscitation may be associated with fewer cases of ARDS compared to crystalloids. Extravascular lung water (EVLW elevation and levels of interleukin-8 (IL-8 and vascular cell adhesion molecule-1 (VCAM-1 have been studied as indicators playing a role in the pathogenesis of ARDS. The aim of the study was to determine the effects of colloid or crystalloid on the incidence of ARDS, elevation of EVLW, and levels of IL-8 and VCAM-1, in swine models with severe sepsis.Methods: This was a randomized trial conducted at the Laboratory of Experimental Surgery, School of Veterinary Medicine, IPB, using 22 healthy swine models with a body weight of 8 to 12 kg. Subjects were randomly allocated to receive either colloid or crystalloid fluid resuscitation. After administration of endotoxin, clinical signs of ARDS, EVLW, IL-8, and VCAM-1 were monitored during sepsis, severe sepsis, and one- and three hours after fluid resuscitation. Analysis of data using the Wilcoxon test , Kolmogorov-Smirnov test, Mann-Whitney test, unpaired t test.Results: Mild ARDS was more prevalent in the colloid group, while moderate ARDS was more frequent in the crystalloid group. EVLW elevation was lower in the colloid compared to the crystalloid group. There was no significant difference in IL-8 and VCAM-1 levels between the two groups.Conclusion: The use of colloids in fluid resuscitation does not decrease the probability of ARDS events compared to crystalloids. Compared to crystalloids, colloids are associated with a lower increase in EVLWI, but not with IL-8 or VCAM-1 levels.

O "ataque " de triatomineos a populações humanas foi possivelmente o mecanismo inicial de abordagem dos triatomineos ao homem, adaptando-se posteriormente ao seu peridomicílio e domicílio, principalmente em áreas desmaiadas ou de cerrado com poucos reservatórios silvestres. No caso do Amazonas, relatado neste trabalho, os triatomineos estavam provavelmente famintos por escassez de outros animais de sangue quente para sua alimentação.

    2018-03-01

    We present a major update to ElecSus, a computer program and underlying model to calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the electric susceptibility of a medium is essential to predict its absorptive and dispersive properties. In this version we implement several changes which significantly extend the range of applications of ElecSus, the most important of which is support for non-axial magnetic fields (i.e. fields which are not aligned with the light propagation axis). Supporting this change requires a much more general approach to light propagation in the system, which we have now implemented. We exemplify many of these new applications by comparing ElecSus to experimental data. In addition, we have developed a graphical user interface front-end which makes the program much more accessible, and have improved on several other minor areas of the program structure.

    Full Text Available A partir del análisis de sus escritos periodísticos, se recupera a Rosario Castellanos como una pionera intelectual del feminismo mexicano. Se defiende la idea de que en sus artículos periodísticos se plasma con fuerza y lucidez un pensamiento feminista moderno, que gira en torno a los efectos del mandato cultural de la feminidad, aportando a la crítica de la situación de las mujeres mexicanas. Castellanos rechaza el victimismo, reivindica la necesidad de terminar con la autocomplacencia femenina y propone que las mujeres se responsabilicen de sus vidas, madurando y puliendo ideas que hoy en día tienen vigencia y radicalidad notables.

    The international SusHouse project has developed a strategy design approach that can contribute to major (factor 20) efficiency improvements in household activities. Stakeholder workshops have been held to develop scenarios for a sustainable future (2050). These scenarios were evaluated on their economic consequences, environmental impacts and consumer acceptance. the results were then used as the input for a second round of stakeholder workshops, which aimed at developing short-term strategies and implementation plans. This Research Note reviews the SusHouse approach and its results. It ends with suggestions for further steps to be taken. A SusHouse CD-ROM is available, containing all final project reports as well as a scenario presentation in the form of images and short texts. 22 refs

    Full Text Available As aveias silvestres são importantes fontes de genes para programas de melhoramento e sua caracterização é fundamental para a efetiva conservação e uso. Por isso, o objetivo deste estudo foi avaliar a divergência genética em uma coleção de 71 subamostras de aveias silvestres, do Banco de Germoplasma da Embrapa Trigo, com base em caracteres multicategóricos e quantitativos. Procederam-se às análises de variância, para os caracteres quantitativos, e multivariada, para ambos os tipos de caracteres. Os métodos de agrupamento UPGMA, a partir da distância euclidiana média (caracteres multicategóricos, e de ligação completa, com base na distância de Mahalanobis (caracteres quantitativos, foram os mais adequados para ilustrar a relação entre as subamostras. A pilosidade da base dos grãos foi o caractere com maior contribuição relativa para divergência genética (32,16% e a menor contribuição foi da pilosidade do nó superior (0,081%. As subamostras divergiram quanto a vinte caracteres: pilosidade da bainha da folha inferior, bordas da lâmina imediatamente abaixo da folha bandeira, nó superior, face externa do lema e base do grão; posição da folha bandeira e das ramificações na panícula; frequência de plantas com folha bandeira recurvada; intensidade da pilosidade do nó superior e da cerosidade do lema; orientação das ramificações na panícula; comprimento dos pelos basais do grão, ráquila, panícula, glumas e planta; cor do lema, tipo de arista, número de grãos por espigueta e ciclo. O germoplasma apresenta elevada variabilidade genética e genes de interesse para o melhoramento de aveias.

    Full Text Available As populações híbridas de pupunha (Bactris gasipaes Kunth acumularam variabilidade genética provenientes de raças primitivas ao seu redor, o que deveria aumentar sua variabilidade. Para testar esta hipótese, avaliou-se a variabilidade genética de populações híbridas por meio de marcadores RAPD utilizando 176 plantas mantidas no Banco Ativo de Germoplasma do INPA, Manaus-AM, sendo quatro populações híbridas [Belém (n=26; Manaus (n=38; Iquitos, Peru (n=41; Yurimáguas, Peru (n=41], duas populações silvestres (B. gasipaes variedade chichagui tipos 1 (n=21 e 3 (n=7, e duas amostras de espécie afim, B. riparia, e compararam-se os parâmetros genéticos com estudos das raças primitivas. Oito iniciadores RAPD geraram 88 marcadores polimórficos e 11 monomórficos. O teste de replicabilidade apresentou uma similaridade de Dice 0,67, considerado aceitável. A heterozigosidade média das populações híbridas foi 0,34 e o polimorfismo foi 87,9%, maiores que nas silvestres (0,31; 74,7%. O dendrograma das similaridades de Dice não apresentou grupos que representassem claramente as populações híbridas. O fluxo gênico entre Iquitos e Yurimáguas (Nm=12,75 e entre Iquitos e Manaus (Nm=9,47 foi alto, enquanto o fluxo entre Belém e Manaus (Nm=7,72 foi menor que o esperado, possivelmente devido à influência da raça Solimões. O alto valor de heterozigosidade em Manaus (0,31 parece ser resultado da união de duas dispersões após a domesticação: a do oeste amazônico, com Iquitos e Yurimáguas, e a do leste amazônico, com Belém, que se juntam em Manaus. No entanto, essas populações não apresentaram acúmulo de variabilidade genética tão expressiva para diferenciá-las das raças primitivas.

    Full Text Available En los Andes colombianos, un gran número de artesanías se fabrican a partir de raíces adventicias de plantas nativas que crecen de forma silvestre. Sin embargo, la deforestación y las prácticas no sustentables han diezmado la disponibilidad de plantas silvestres productoras de fibra. En este estudio evaluamos la disponibilidad de fibras de tres especies en Santa Elena (Antioquia, Colombia: Asplundia sarmentosa, Philodendron aff. sagittifolium y Clusia multiflora. Después de una búsqueda exhaustiva en la zona de estudio ubicamos menos de 30 individuos adultos de cada especie. Para cada planta se midieron las variables asociadas al tamaño de la planta y se registró el número y la longitud de raíces maduras e inmaduras. Se pesaron fragmentos de raíces para estimar la biomasa. El crecimiento de raíces de cada planta fue monitoreado mensualmente durante siete meses. La disponibilidad actual de fibra (raíces maduras es de ca. 3 352 m (Asplundia 1 481 m, Clusia de 952 m, Philodendron 918 m, con esta cantidad de material se pueden elaborar entre 419 a 838 canastos. De acuerdo a la tasa de crecimiento mensual, una nueva raíz podría alcanzar un tamaño para ser cosechado entre el mes 38 y 71. Plantas más grandes tienen mayor cantidad de raíces maduras, sin embargo, la tasa de crecimiento no está asociada al tamaño de la planta. Nuestros resultados proveen evidencia de que las plantas en Santa Elena presentan una relación (tamaño de la planta, número de raíces maduras que es similar a plantas que se encuentran en zonas no intervenidas, no obstante, la cosecha de fibras en Santa Elena no es una actividad sostenible debido al bajo número de individuos susceptibles de ser cosechados, la lenta tasa de crecimiento de raíces y la alta demanda de fibras. Es necesario implementar estrategias como el enriquecimiento del bosque con estas tres especies para garantizar una actividad sustentable para recolectores y artesanos en Santa Elena y

Observou-se que os acessos de A. stenosperma são semelhantes, apesar da sua grande distância geográfica, e diferem das demais espécies, formando um grupo mais coeso. Caracteres como o diâmetro do eixo central e o comprimento dos frutos e das sementes serviram para distingui-la das demais espécies. Arachis decora apresentou alta variação entre acessos nos vários caracteres morfológicos estudados. A. palustris apresentou alta variação morfológica entre acessos, ainda que tenham sido analisados apenas dois, para altura da planta, largura da semente, dimensões do esporão, istmo, folíolo, raque e eixo central e quanto à presença e ausência de tricomas no folíolo. Arachis praecox, representada por um único acesso, aproximou-se mais de A. decora que das demais espécies.

El objetivo de este trabajo fue estudiar los efectos de la fragmentación de poblaciones en la viabilidad de Alouatta palliata y Cebus capucinus en el Refugio de Vida Silvestre Privado Nogal (RVSPN, Sarapiquí, Heredia. Para esto se uso el programa VORTEX para correr un análisis de viabilidad de poblaciones (PVA para ambas especies. La información utilizada en el PVA proviene de la estructura demográafica de las poblaciones del RVSPN, literatura sobre la historia natural de las especies y artículos relacionados con PVA. Los resultados sugieren que tanto A. palliata como C. capucinus pueden sobrevivir en fragmentos boscosos aislados. Sin embargo, si se incorporan factores como depresión por endogamia, catástrofes o perdida de hábitat, las pequeñas poblaciones fragmentadas se vuelven inestables y aumenta el riesgo de que desaparezcan. Las poblaciones continuas fueron más robustas ante las amenazas incorporadas, por lo que se recomienda continuar con la reforestación para unir los fragmentos boscosos. Es importante darle seguimiento a las poblaciones de ambas especies y tener un manejo de su hábitat para disminuir los efectos negativos de diferentes eventos estocásticos provocados por el ambiente.Population viability of Alouatta palliata (Primates: Atelidae and Cebus capucinus (Primates: Cebidae at Refugio de Vida Silvestre Privado Nogal, Sarapiquí, Heredia, Costa Rica.

    Full Text Available The aim of the present work conducted at the Refugio de Vida Silvestre Bahía Samborombón is to analyse the most relevant aspects of the fecundity of Chasmagnathus granulatus and Uca uruguayensis. Samplings were carried out from March 2001 to February 2003. Ovigerous females of U. uruguayensis (N = 13 and C. granulatus (N = 25 were found during spring and summer, their sizes (CW varied from 9.1 to 11.7 µm for the former species and from 22.8 to 32.4 mm for the latter. The egg diameter in U. uruguayensis ranged from 245 to 260 µm for embryos in the early stage of development and from 250 to 345 µm for those in mid-developmental stage, while in C. granulatus from 250t o 345 µm and from 260 to 365 µm respectively. Fecundity varied from 1126 to 6745 eggs/brood in U. uruguayensis and 15688-57418 eggs/brood in C. granulatus. For those females with broods in mid-developmental stage, several relationships were made. For U. uruguayensis the best correlation coefficients were obtained for the relationships: female weight vs. egg mass weight and carapace width vs. egg mass weight; for C. granulatus the best association was obtained between female size and the egg number and the egg mass weight.

Los productos de fusión fueron cultivados en el medio V-KM suplementado con albúmina de suero bovino. Las primeras divisiones celulares ocurrieron a los 3 a 4 días de cultivo. Después de la formación de colonias se observó una rápida proliferación de callos, a partir de los cuales se regeneraron 19 plantas. El análisis molecular usando RAPD, confirmó que los regenerantes presentaban segmentos de ADN de ambos parentales, sugiriendo su posible naturaleza de híbridos somáticos. Las observaciones del número de cromosomas indicaron que todos los híbridos fueron aneuploides. En condiciones de invernadero, los regenerantes derivados de la fusión de protoplastos, mostraron características morfológicas intermedias entre las líneas parentales. Este estudio muestra la producción de híbridos somáticos de papa con el método de fusión presentado.

    Sus1 is a conserved protein involved in chromatin remodeling and mRNA biogenesis. The SUS1 gene of Saccharomyces cerevisiae is unusual, as it contains two introns and is alternatively spliced, retaining one or both introns in response to changes in environmental conditions. SUS1 splicing may allow the cell to control Sus1 expression, but the mechanisms that regulate this process remain unknown. In this thesis project, we have investigated whether the structure adopted by SUS1 RNA sequences co...

    Multilayered sheet metals have been widely used to achieve a wide range of favorable mechanical, physical, thermal and electrical properties. Laser beam irradiation over these materials creates extreme temperature changes that can lead to changes in the microstructural properties. Microstructure plays a very crucial role in determining the mechanical property of the irradiated region, thus determining the optimum laser processing conditions. In this study, metallographic studies, as well as tensile, fatigue and hardness tests, are undertaken on SUS430/C11000/SUS430 laminated composites that have been exposed to laser irradiation with different number of passes. This composite can be used in the microelectronics industry since it has the anti-corrosion and strength capability of stainless steel, and the electrical superiority of copper. Ytterbium fiber laser is used in such a way that the governing mechanism of the process is the temperature gradient mechanism. Evolution of the microstructure is revealed by metallography, and the fracture levels of tension and fatigue test specimens are further evaluated by SEM. This study illustrates the significant effects of successive laser irradiation on the evolution of microstructure and mechanical properties, which lead to some suggestions for improving the properties of laser-formed SUS430/C11000/SUS430 composites.

    Full Text Available Clones de batata silvestre (Solanum spp. foram analisados quanto aos teores de matéria seca em tubérculos e isoenzimas de aspartato transaminase e isocitrato desidrogenase em folhas, com o objetivo de identificar associação entre estas características. Os resultados obtidos em uma amostra de 50 clones indicam grande variabilidade do teor de matéria seca. Clones de S. commersonii malmeanum apresentaram maior teor que os de S. commersonii commersonii, S. chacoense muelleri e de outros cuja espécie não foi identificada. Os padrões isoenzimáticos de folhas de 38 clones da amostra mostraram 15 variantes eletroforéticas de aspartato transaminase e sete de isocitrato desidrogenase. Comparações efetuadas através de tabelas de contingência 2 x 2, usando o teste de chi², com correção para continuidade, permitiram concluir que existe associação significativa entre o teor de matéria seca e as bandas de mobilidade relativa 1,00 de aspartato transaminase e de isocitrato desidrogenase.Wild potato clones (Solanum spp. were analysed for tuber dry matter content, leaf aspartate transaminase and leaf isocitrate dehydrogenase isoenzymes in order to identify association between these characteristics.

    2011-07-01

    Full Text Available El presente trabajo es la primara aproximación acerca del papel de las plantas con órganos de almacenamiento subterráneos comestibles (POAS en la Patagonia, desde una perspectiva temporal y espacial, al integrar datos etnohistóricos y etnográficos actuales ligados al uso de las POAS. El 75 % de las 54 fuentes analizadas mencionan el uso de POAS en la alimentación humana de la Patagonia. Las POAS silvestres comestibles registradas ascienden a 51 especies, siendo mayor el conjunto de POAS con raíces comestibles. La estepa y zonas ecotonales resultaron las de mayor riqueza de POAS, probablemente vinculado a adaptaciones ecológicas de éstas a la aridez en el primer caso, como a la alta diversidad relativa que presentan los ecotonos, en el segundo. El registro etnohistórico mostró discontinuidades marcadas, siendo pocas las especies presentes por más de un siglo, destacándose la continuidad documental de A. tuberosa desde el siglo XVIII al presente, así como la incorporación reciente de especies exóticas. Las fuentes etnohistóricas revisadas y su contraste con datos etnobotánicos recientes de campo sugieren dinamismo en los patrones de utilización, que a lo largo del tiempo han llevado al abandono del uso de las POAS en la práctica alimentaria de la Patagonia. Las singularidades encontradas respecto a lo temporal y espacial pueden vincularse tanto a los conocimientos locales y específicos desarrollados a lo largo del tiempo por los habitantes de la Patagonia, como también a las circunstancias sociopolíticas y académicas de cada una de las fuentes analizadas.

    Full Text Available El objetivo del presente trabajo fue relevar el elenco de abejas silvestres en la región central de Santa Fe y comparar la diversidad de especies y aspectos biológicos en dos ambientes de una misma región. Las abejas fueron colectadas en el estrato herbáceo de la Reserva Universitaria “Escuela Granja” de la localidad Esperanza, y en la zona urbana de la localidad Susana, ambas ubicadas dentro de la Provincia Fitogeográfica del Espinal. La colecta se realizó en octubre, noviembre y diciembre de 2004 y en enero, febrero y marzo de 2005, registrando las especies vegetales sobre las que se capturaron. Se colectaron 277 ejemplares en total, de los cuales se identificaron 62 especies (27 géneros en 5 familias. Las curvas de rarefacción indican una tasa de acumulación de especies mayor para la Reserva Ecológica, los índices de diversidad de Shannon son 3,25 para la Reserva Ecológica y 2,64 para la Zona Urbana. Para la comparación de las comunidades en ambos sitios, las abejas fueron clasificadas en tres categorías según la especialización en el uso del recurso floral, sustrato de nidificación y comportamiento social. Se observó una asociación entre los grupos especialistas y de nidificación en el suelo con el ambiente natural, y por otro lado, las especies generalistas y de nidificación en cavidades con el ambiente urbano. No se identificaron diferencias, en cuanto al tipo de comportamiento social de las especies, entre ambos sitios.

    Full Text Available En agosto de 1934 el Padre Francisco Savary, misionero de la Compañía Montfort, da la voz de alarma acerca de unos casos de fiebres que se han presentado en unas veredas del vecindario de Restrepo y cuyo cuadro clínico corresponde al descrito en el capítulo de fiebre amarilla de su Manual de Misionero. Se practica una primera investigación encontrando, en efecto, manifestaciones mórbidas que sugieren fiebre amarilla. El brote presenta una característica extraña que confunde a primera vista la investigación, en un momento en que la noción de la fiebre silvestre, o sea sin Aedes aegypti, no está aún generalizada. No se encuentra tal zancudo en la región. A consecuencia de un informe de la Dirección Nacional de Higiene, el Dr. E. R. Rickard, médico de la Fundación Rockefeller, baja a Villavicencio y me deja instrucciones precisas, con elementos de investigación. En esta época el autor era Director Intendencial de Higiene. Se toman 30 muestras de sangre distribuídas entre personas convalecientes de ataques de la enfermedad, entre personas que moraban en las casas en que habían ocurrido casos y entre compañeros de trabajo de personas atacadas. De las muestras sometidas a la prueba de inmunidad para fiebre amarilla, 20 resultaron positivas, 2 inconclusivas y 8 negativas. Estos resultados traen por consecuencia el establecimiento de una comisión de investigación epidemiológica en la región de Restrepo.

    Full Text Available A review on the conceptual basis and aims of Landscape Ecology, scientific discipline that presents an important geographical component, is realized. It assumes that landscape heterogeneity controls diverse movements and flows of organisms, matter and energy. One of the principal objects of study of the above mentioned discipline is the existing relations between landscape structural patterns and dynamics of wild populations and communities. This is an aspect of great applicability in biodiversity conservation and land-use planning policies. In relation to this subject matter, transdisciplinarity of Landscape Ecology is described.

    Se realiza una revisión sobre las bases conceptuales y los objetivos de la Ecología del Paisaje, disciplina científica que presenta un importante componente geográfico. Como punto de partida asume que la heterogeneidad espacio-temporal del paisaje, resultante de la interacción dinámica de las sociedades humanas con el medio, controla diversos movimientos y flujos de organismos, materia y energía. Uno de los principales objetos de estudio de dicha disciplina son las relaciones existentes entre los cambios estructurales del paisaje y la dinámica de poblaciones y comunidades silvestres, configurándose como un aspecto de gran aplicabilidad en las políticas de conservación de la biodiversidad y de planificación territorial con base ecológica. En relación a esta temática, se describe el carácter transdisciplinar de la Ecología del Paisaje.

    Full Text Available

    En Colombia la rabia ocurre en dos ciclos epidemiológicos principales: la rabia urbana con el perro como principal reservorio y transmisor principalmente a humanos, y la rabia silvestre con especies animales de la vida silvestre como los quirópteros y zorros entre otros, como reservorios y transmisores principalmente a especies ganaderas y eventualmente a humanos que se convierten en víctimas accidentales. Durante los últimos años la rabia silvestre en Colombia ha cobrado mayor relevancia como problema de salud pública que la rabia urbana, a juzgar por el número de víctimas humanas. Con el fin de perfeccionar el diagnóstico y la tipificación del virus de la rabia en Colombia, el Laboratorio Nacional de Referencia del Instituto Nacional de Salud estandarizó técnicas para amplificar y secuenciar un fragmento de ADN complementario (cADN a una fracción de 902 nucleótidos seleccionados del ARN del virus, con el fin de adelantar estudios de epidemiología molecular. La fracción mencionada contiene secuencias que codifican para los aminoácidos 447-525 de la glicoproteína y 1-35 de la proteína L. Además contiene la región intergénica no codificante conocida como Pseudogen Psi.

    Las técnicas estandarizadas fueron las siguientes: a extracción de ARN total a partir de cerebro de ratón infectado. b amplificación molecular por transcripción reversa y reacción en cadena de la polimerasa. c secuenciación del fragmento amplificado.

    Mediante estas técnicas de epidemiología molecular viral se determinó que durante 1994-2004, la rabia urbana se concentró en tres regiones geográficas definidas, con epizootias en el antiplano cundiboyacense, departamento de Arauca y la región Caribe. Las dos primeras se controlaron

    Habitat destruction may cause wildlife population fragmentation and is considered an important factor in small population species extinction. As wildlife populations become smaller, threats to their stability and persistence arise as a result of demographic, environmental and genetic stochastic factors. The aim of this work was to study the effects of population fragmentation on the long term viability of Alouatta palliata and Cebus capucinus populations, at Refugio de Vida Silvestre Privado Nogal, Sarapiquí (RVSPN), Heredia. For this we used the computer software VORTEX to run a population viability analysis (PVA) for both species. The input data of the PVA were taken from the demography structure of the RVSPN, literature sources from the species and from PVA related papers. We evaluated two sets of scenarios: small fragmented populations to reflect the population current state, and one larger and continuous population, to reflect the effect of reforestation actions followed by RVSPN to connect forest fragments. Results suggest that both A. palliata and C. capucinus can survive in isolated forest fragments. However, if different factors as inbreeding depression, catastrophes or habitat loss were incorporated to the scenarios, the small fragmented populations become unstable and the risk of extinction increased for both species. Continuous and larger populations were more robust against the threats incorporated in the scenarios when compared to the current situation of smaller and fragmented populations. The best management option for both species would be to continue reforestation efforts in the area to connect forest fragments, with the result of larger and continuous populations of both species. It is important to continue the observation of both species populations, and to promote a habitat management to reduce the negative effects of stochastic environmental events.

    Full Text Available Durante os anos de 1982 a 1986, a investigação sobre mamíferos comensais e silvestres, da periferia da cidade de Jacobina, Bahia, mostrou, ao lado do escasso número de exemplares, uma reduzida variedade específica dessa fauna. Capturou-se apenas 11 espécies, entre as quais, predominou o Didelphis albiventris, que abrangeu 44% dos 213 espécimens capturados. Entre os 193 com exames já concluídos, 84 eram exemplares de D. albiventris e 2 estavam infectados pela Leishmania donovani senso lato, 1 por L. mexicana amazonensis, 1 por L. braziliensis, subespécie e 3 por Trypanosoma cruzi Também foram observadas formas suspeitas de serem amastigotas de leishmanics, nos esfregaços de órgãos de 3 exemplares de Dasyprocta aguti, 1 Cercomys cunicularius - e 1 Oryzomys eliurus. 0 restante dos exemplares, inclusive 14 de Lycalopex vetulus, estava negativo para flagelados. Apesar de reforçado por outros indicadores epidemiológicos, como a predominância específica, a freqüência domiciliar, a atratividade para a vetora Lutzomyia longipalpis, e a concomitância com casos humanos nos mesmos locais, o índice de 2,3% de infecção natural do Didelphis albiventris, não autoriza a conclusão definitiva de ser o marsupial o mais importante reservatório natural da leishmaniose visceral em Jacobina.

    Full Text Available Se analizó el comportamiento de la dinámica de poblaciones silvestres de chigüiros bajo diferentes condiciones del hábitat y presiones antrópicas, y se formuló una herramienta técnica para apoyar la gestión de manejo que realiza la autoridad ambiental regional relacionada con el aprovechamiento sostenible y la conservación de la especie. Se generó un modelo de simulación determinístico que representa la dinámica de poblaciones silvestres de chigüiros, como resultado de procesos biológicos de natalidad y mortalidad, y del aprovechamiento extractivo anual de individuos en hatos de los municipios de Paz de Ariporo y Hato Corozal (Casanare, Colombia. Una interfase fue diseñada para facilitar el uso del modelo y construir escenarios para simular diferentes alternativas de manejo. El modelo fue usado para evaluar el efecto a largo plazo de la cosecha o extracción de individuos mediante la caza comercial, la cosecha selectiva de adultos por sexos, la presencia de adecuaciones y la variación del área de hábitat adecuado disponible sobre la tendencia de abundancia de tres poblaciones silvestres de chigüiros en la zona de estudio. Las simulaciones realizadas bajo los diferentes escenarios permitieron establecer las distintas respuestas de cada población a los cambios realizados en la tasa de cosecha y el área de hábitat y así recomendar acciones de manejo. Los escenarios evaluados destacan la importancia de hacer una extracción selectiva de adultos por sexos para realizar un aprovechamiento sostenible de la población y garantizarsu conservación. Así mismo, se destaca la importancia de mantener mayores áreas con hábitat adecuado.

Currently, 12 of these 71 plants have been approved to be used in SUS (Public Health System, the remaining species still need further research. Thusly, this review aimed to seek information from toxicological studies on the plants that have not yet been officially approved, to stimulate new research in the field, promoting an economical and functional impact. In order to obtain the information, the keywords plant name + toxicity and/or toxicological studies were searched in the most prominent databases, both in English and in Portuguese. The ten plants with the most references were included in this review. Among the ten plants assessed, three have all the required studies required by the National Health Surveillance Agency, two of which we recommend the immediate adoption by SUS. In general, three plants have a determined LD50, nine have reproductive toxicity data, and five have not yet shown any sign of toxicity.

    Full Text Available El interés de las ciencias aplicadas al deporte en los espectadores y el espectáculo deportivo ha sido más bien escaso y en muchos casos sobrecentrado en la violencia. El objetivo de este trabajo es proponer una clasificación alternativa de los aficionados al fútbol a partir del tipo de contacto que tienen con el espectáculo y describir sus valores, motivaciones y compromiso. Mil setecientas diecinueve personas asistentes a partidos de fútbol organizados por la Liga de Fútbol Profesional contestaron cuestionarios sobre sus valores, motivaciones y relación con el fútbol. Los resultados muestranque los entusiastas son los aficionados más motivados y comprometidos con el fútbol al mismo tiempo que participan significativamente más de valores relacionados con el conservadurismo y la autopromoción que las otras tres categorías (espectadores, aficionados presenciales y aficionados virtuales. La clasificaciónpropuesta en base al tipo de contacto con el fútbol permite conceptualizar el fútbol como algo más que lo que ocurre en los estadios y abre las puertas a intervencionesdesde lo positivo para promover el fair play y la deportividad en los aficionados.

    Full Text Available In 2005 the Argentinian writer Eduardo Sacheri published The Question in Their Eyes (La pregunta de sus ojos.  The novel narrates on a double level, both fictional and temporal, the decision of a retired prosecutor to come to terms with a case of rape and murder which had taken place years earlier: his life had been shattered by the consequences of that tragedy, and writing about it would be a way to start living again.  The director Juan José Campanella - widely famous for having directed episodes of the television series Law & Order, but especially as the director of successful films such as El hijo de la novia - decided to adapt the novel and involved Sacheri in the project: the close collaboration between writer and director produced a bold screenplay that adds to the noir thriller a more romantic dimension.  Disproving the commonplace of the writer jealous of his work, they wrote together a new version which retains certain elements of the original text, but also introduces a number of relevant changes to the structure, characters and ending of the novel.  The Secret in Their Eyes  (El secreto de sus ojos, shot in 2008, was released the following year and in 2010 won the Academy Award for best foreign language film.

    Full Text Available The fatty acid composition of 34 species of plants from a variety of families that grow wild in the Iberian Peninsula was analysed. The aim to the survey was to indentify oils that contain a mix of fatty acids that from a qualitative or quantitative point of view have a commercial value. Because of the diverse taxonomic origin of the samples, the oil content between species was very variable, fluctuating between an average value of 3.4% in the Caryophyllaceae and 31.1% in Euphorbiaceae. Like the oil content, the fatty acid composition was quite variable, but, in general, the main fatty acids were palmitic, oleic, linoleic and linolenic acid, while in the Brassicaceae and in the Apiaceae erucic acid and petroselinic acid were the principal fatty acids respectively.

    Se ha estudiado la composición en ácidos grasos del aceite de las semillas en 34 plantas silvestres de la Península Ibérica. Se pretende la obtención de aceites con una composición en ácidos grasos que cualitativa o cuantitativamente puedan resultar de interés desde un punto de vista comercial. Debido al origen taxonómico tan diverso de las muestras, el contenido en aceite resulta muy variable, oscilando entre un valor medio del 3.4% en las Caryophyllaceae y el 31.1% de media en las Euphorbiaceae. Como el contenido en aceite, la composición en ácidos grasos es también bastante Variable, pero en general los principales ácidos grasos son palmítico, oleico, linoleico y linolénico, mientras que en las Brassicaceae domina el ácido erúcico y en las Apiaceae el ácido petroselínico.

    Full Text Available Estudou-se o comportamento reológico de méis de Apis mellifera produzidos no estado do Piauí, no semi-árido brasileiro, elaborados com florada predominante de silvestre (Serjania glabrata. As amostras foram coletadas ao longo do ano 2000, a partir de coletas realizadas por apicultores, associações e cooperativas de apicultura da região abrangida pelos municípios de Picos, Itainópolis, Vera Mendes e Isaías Coelho. Após as coletas as amostras passaram pelos processos de centrifugação, filtragem e decantação. As medidas reológicas foram feitas nas temperaturas de 20 a 40 ºC utilizando-se um viscosímetro Brookfield, modelo RVT. As leituras de velocidade de rotação e torque foram transformadas em valores de taxa de deformação e tensão de cisalhamento. Os dados de taxa de deformação e tensão de cisalhamento foram ajustados pelas equações da Lei-da-Potência e de Herschel-Bulkley. As amostras apresentaram comportamento pseudoplástico. As equações se ajustaram adequadamente aos resultados experimentais de tensão de cisalhamento em função da taxa de deformação. O aumento de temperatura reduziu a viscosidade aparente em níveis próximos de 80%. Os valores de viscosidade aparente foram bem ajustados por uma equação do tipo Arrhenius.The rheological behavior of Apis mellifera honey produced in the State of Piauí, in the Brazilian semi-arid, obtained with predominance of Serjania glabrata flowers was studied. The samples were collected in the year 2000 by beekeepers and associations and cooperatives of beekeepers in the area covered by the municipal districts of Picos, Itainópolis, Vera Mendes and Isaías Coelho. The samples were centrifuged, filtered, decanted and the rheological measures at temperatures of 20 to 40 ºC using a Brookfield Viscometer RVT model were made. The readings of rotation speed and torque were transformed in shear rate and shear stress values. The data of shear rate and shear stress were fitted

    Full Text Available Apresentaram-se os resultados das observações sobre o comportamento de formas adultas de Culicidae silvestres na área de Casa Grande, de zona de florestas primitivas situada na parte nordeste do Estado de São Paulo, Brasil. As investigações focalizaram os mosquitos de hábitos diurnos e crepusculares-noturnos, durante o período de 1963 a 1966. Foram obtidos dados concernentes à composição especifica, distribuição, ciclo anual da densidade, estratificação vertical na floresta e possíveis relações com o ambiente doméstico. A região estudada é considerada como bioma ou ecossistema do Anopheles (Kerteszia cruzii e, dessa maneira, êsse mosquito compareceu de maneira predominante nas observações, merecendo por isso especial atenção. As outras espécies distribuiram-se predominantemente entre os Sabethini, além de alguns Culicini. No que concerne à domesticidade, o Anopheles cruzii apresentou-se como apreciável freqüentador das casas, seguido pelo Aedes serratus. Além disso, aquele anofelino mostrou-se acentuadamente acrodendrófilo, parecendo ser dotado de alguma ornitofilia.This work reports observations on adult Culicidae activities for diurnal and crepuscular-nocturnal forest species occurring in the area of Casa Grande, located at the Northeast region of the State of São Paulo, Brazil. These investigations, were carried out during the 1963 to 1966 period. They recorded the specific composition, distribution, year cycle of abundance, vertical stratification in the forest, and the possible relationship of these forest mosquitoes to the housekold environment. Since these region is considered a biome of the Anopheles (Kerteszia cruzii particular attention was dedicated to this species, considered as an important malaria vector. Beside this, several Sabethini species proved to be considerably abundant and, along with some culicines as Aedes serratus, showed activities that may put these mosquitoes in relation with humans

    José Augusto Pina

    Full Text Available Este artigo discute a interlocução do sindicalismo brasileiro com o Sistema Único de Saúde (SUS e os planos e seguros privados de saúde. São ponderadas algumas teses na Saúde Coletiva à luz de estudos mais recentes nas Ciências Sociais sobre o sindicalismo e realizada análise documental para o caso da Central Única dos Trabalhadores (CUT, tomado aqui como referência. Aponta-se a necessidade de considerar os pesos relativos que a ação sindical atribuiu a cada um dos aspectos da relação, SUS e planos privados de saúde, pelas distintas conjunturas do país. O conflito entre trabalhadores e empresas somado ao desemprego e à precarização do trabalho expõe os limites das coberturas assistenciais privadas e impele a representação sindical a pleitear a intervenção estatal. O trabalho refletiu sobre as distintas modalidades de ação sindical na empresa e no Estado. A complexidade dessa dinâmica fez emergir um setor sindical interessado na gestão da previdência complementar e dos planos de saúde e, ao mesmo tempo, recria as circunstâncias e traz novas possibilidades de as organizações sindicais se colocarem na cena política e aglutinar os interesses de amplos segmentos dos trabalhadores para pressionar o Estado na defesa da melhoria do sistema público de saúde.

Estes dados foram comparados com os encontrados na literatura especializada e verificado diversidades nos comportamentos parasitológicos das linhagens em estudo, quando comparados com os encontrados nas linhagens H e S oriundas do Vale do Rio Paraíba do Sul, no Estado de São Paulo (Brasil.The wild (W and human (H strains of Schistosoma mansoni were isolated in the Lowland Region of the Maranhão State (Brazil. The snail progenies from Biomphalaria glabrata collected from that region were exposed to the W miracidia, obtained from livers of wild rodents, and H miracidia from eggs in human stools. A control gruop of normal snails was kept in the same conditions as the infected one. The date of the elimination of cercariae, the quantity of eliminated larvae, the infection index of the moluscs and the mortality rate of the snails were recorded. These data suggested better adaptation of the H strain to B. glabrata. The W strain presented three times more virulence to snails than the H strain. These results were compared with published

O objetivo deste artigo é situar no contexto das reformas de estado pensadas na década de 90 para o Brasil, as propostas de mudança dos modelos de gestão da administração pública, com foco no processo de implementação do SUS. Essa abordagem trata em primeiro lugar da personalidade jurídica das organizações de saúde na esfera estatal, conceituando o público a partir de seus objetivos; em segundo, discute o contexto as reformas de estado e as mudanças propostas para a administração pública. Os autores entendem que critérios e parâmetros para avaliação institucional devem contemplar quatro aspectos: subordinação à política de saúde; legalidade; eficiência gerencial e capacidade de controle. A partir do quadro de referencia geral elaborou-se uma análise comparativa em relação à proposta das fundações públicas de direito privado. Na análise comparativa das características desse tipo de entidade proposta para gestão hospitalar, observam-se semelhanças com a proposta de Organizações Sociais. Fundação Estatal e Contrato de Gestão podem ser vistos como modelos que possibilitam modernizar o Estado, além de re-introduzirem o tema da reforma hospitalar na agenda governamental brasileira.The recent document on Public Foundations issued by the Ministry of Planning (2005 and the crisis in the hospital area bring the issue of public management models back to the agenda of Brazil's National Health System (SUS.

    Full Text Available Como agente reflexivo de su propia práctica, el profesorado construye creencias pedagógicas sobre el proceso de enseñanza y aprendizaje y, en particular, sobre el rol que sus estudiantes deben asumir en el aprendizaje de un idioma. Este estudio tiene como objetivo identificar las creencias pedagógicas de treinta docentes de inglés de primaria, secundaria y terciaria, en Chile, sobre el rol estudiantil en el proceso didáctico. Un cuestionario, una entrevista semi-estructurada, un diario auto-biográfico y cinco diarios de observación no-participante fueron utilizados para revelar las creencias pedagógicas de sus informantes. Los datos arrojados por los instrumentos fueron analizados con el programa cualitativo ATLASTI, que permitió el levantamiento de tres dimensiones y diez categorías, mediante el uso de la técnica del análisis de contenido semántico. Los resultados muestran que los tres grupos de profesorado declaran que estudiantes que aprenden una lengua extranjera deben tener características personales y académicas relacionadas con la motivación, la participación, la autonomía, entre otras; sin embargo, al interior del aula asumen un rol pasivo y reactivo frente al ambiente de enseñanza altamente estructurado que genera el personal docente. En conclusión, las creencias que cada docente sostiene se alimentan de la teoría y se corroboran o cuestionan en la práctica de aula, a modo de una relación bidireccional entre teoría y práctica, y viceversa.

Several species of the genus Arachis are resistant to pests and diseases. The objective of our experiments was to identify wild species belonging to the taxonomic section Arachis with either A or B (or " non-A" genomes that are resistant to early leaf spot (Cercospora arachidicola, late leaf spot (Cercosporidium personatum and rust (Puccinia arachidis. For the identification of genotypes resistant to fungal diseases, bioassays with detached leaves were done in laboratory conditions, with artificial inoculation, a controlled temperature of 25ºC and a photoperiod of 10 h light/14 h dark, for 20-42 days, depending on the fungi species. Most of the accessions of wild species were more resistant than accessions of A. hypogaea for one, two or all three fungi species studied. Arachis monticola, considered to be a possible tetraploid ancestor or a derivative of A. hypogaea, was also more susceptible to Cercosporidium personatum and Puccinia arachidis, as compared to most of the wild species. Therefore, wild germplasm accessions of both genome types are available to be used for the introgression of resistance genes against three fungal diseases of peanut.O amendoim (Arachis hypogaea possui genoma AB e é uma das mais importantes culturas oleaginosas em todo o mundo.

    Full Text Available La historia militar de Cartagena de Indias está ligada a la doble condición de ser centro de intercambio con reputación de opulencia, y de constituirse con el tiempo en puntal geopolítico por sus condiciones defensivas. De estos dos aspectos, el que ha despertado el mayor y más temprano interés historiográfico por su sabor romántico ha sido la narración de los épicos ataques y defensas de la ciudad colonial antes y después de rodearse de murallas de piedra. Desde cuando el noble francés Jean François de la Roque, señor de Roberval , compañero de Cartier en las tempranas expediciones al Canadá y conocido en las crónicas como Roberto Baal u O'valle, la sorprendiera en 1544, Cartagena nunca dejó de vivir bajo la amenaza de "enemigas venganzas".

    Full Text Available Las playas son sistemas donde se ejercen presiones antrópicas y ambientales, en este estudio se analizaron sus condiciones bioeconómicas con la finalidad de obtener un modelo que permita determinar el grado de vulnerabilidad y la matriz de riesgo en las playas del Estado de Quintana Roo para un mejor uso sustentable. Se formularon matrices con registros biológicos y socioeconómicos obtenidos entre el 2009 y 2010 en temporadas de alto registro turístico, obteniendo 17 variables en 20 playas analizadas. La evaluación se efectuó con el modelo semiparamétrico del tipo KSIM con dos escenarios: uno sin control/restricción en el desarrollo costero y otro con las mismas características pero con decremento en demanda turística por baja calidad ambiental. Los resultados mostraron un marcado descenso en playas arenosas y costas rocosas. En el modelo se hace referencia a la importancia de los procesos de las playas y su interrelación con los factores biológicos, sociales y económicos más importantes, proporcionando una visión integral de todas las variables. Se recomienda incrementar el modelo dándole mayor envergadura, integrando a las instituciones que influyen en el control de las acciones en estas playas, lo que dará un mejor referente y monitoreo a corto, mediano y largo plazo.

São ponderadas algumas teses na Saúde Coletiva à luz de estudos mais recentes nas Ciências Sociais sobre o sindicalismo e realizada análise documental para o caso da Central Única dos Trabalhadores (CUT, tomado aqui como referência. Aponta-se a necessidade de considerar os pesos relativos que a ação sindical atribuiu a cada um dos aspectos da relação, SUS e planos privados de saúde, pelas distintas conjunturas do país. O conflito entre trabalhadores e empresas somado ao desemprego e à precarização do trabalho expõe os limites das coberturas assistenciais privadas e impele a representação sindical a pleitear a intervenção estatal. O trabalho refletiu sobre as distintas modalidades de ação sindical na empresa e no Estado. A complexidade dessa dinâmica fez emergir um setor sindical interessado na gestão da previdência complementar e dos planos de saúde e, ao mesmo tempo, recria as circunstâncias e traz novas possibilidades de as organizações sindicais se colocarem na cena política e aglutinar os interesses de amplos segmentos dos trabalhadores para pressionar o Estado na defesa da melhoria do sistema público de saúde.The article intends to discuss the patterns of interlocution between the Brazilian trade unionism, the public health system (SUS and the private health insurance sector.

    Corrosion resistance of diffusion bonded joint with Ta foil inserted between the bonded surfaces and friction welding joint for SUS304L and Zr was examined in 3N-HNO{sub 3} solution contained Cr{sup 6+} ion. In a short term dipping test, it was difficult to qualitatively investigate the corrosion property for both joints, because it depended strongly on the surface condition (preparation) of the specimen before the test. In a long term dipping test, however, the type of the corrosion was mainly found intergranular corrosion in SUS304L base metal for all of the joints, moreover this developed the falling off the crystal grain of SUS304L base metal. In this corrosion process, a possibility that galvanic potential difference between dissimilar metals accelerated corrosion was pointed out, then local potential gradient was investigated using a measuring system, in which a sharp vibrating probe was scanned across the joint interface. SUS304L base metal showed a positive local potential gradient which indicated on acceleration of corrosion in SUS304L. But it was not so large and corrosion rates of SUS304L for the both solid state joining were nearly same value as that without Zr or Ta base metals. The acceleration of the corrosion at dissimilar metal joints were not observed from the results of the dipping test and the measurement of the local potential gradient, it is considered that there is no problem of the corrosion resistance in these joints.

  19. Difference in cold-working effect on the irradiation-induced deformation between SUS 316L and SUS 304 stainless steel

    SUS 304 stainless steel has been used for internal components of the light-water reactors constructed in earlier days, in which irradiation-assisted stress corrosion cracking has drawn attention. SUS 316L was regarded as less susceptible to the stress corrosion cracking and adopted in the newer reactors, although it was recently found not completely so in some Japanese reactors. Tensile residual stress introduced during manufacturing is believed to be one of the major factors in the initiation of cracking. It is, therefore, essential to assess the stress relaxation behavior under irradiation, which can be evaluated from the irradiation creep data, in conjunction with the effect of cold work. In the present study, creep experiments under 17MeV proton irradiation (2x10 -7 dpa/s) at 288degC were conducted for both SUS 316L and SUS 304 stainless steels with 5% or 25% cold work. Stress dependence of the irradiation creep was quite different between the two stainless steels, almost linear in SUS 316L while nearly quadratic in SUS 304 for both levels of cold-working. Stress relaxation under irradiation was evaluated to be different between the two stainless steels, reflecting their difference in stress dependence. (author)

A produção de serviços hospitalares no SUS demonstra importante redução da oferta agravada pelo crescimento demográfico e por expectativas definidas por disposições constitucionais. A redução é seletiva e concentrada em serviços obstétricos e de clínica médica e nos serviços privados lucrativos. Para se garantir acesso equitativo é necessário: ampliação de gastos públicos; redução dos gastos por desembolso direto; reformas organizacionais; ampliação da capacidade de governo.We analyze Brazilian health system in comparative perspective.

Los efectos de este problema repercuten notablemente en aquellos que sobreviven, ya que las consecuencias a largo plazo del maltrato infantil son más perjudiciales para lasvíctimas y sus familias, y más costoso para la sociedad, que las lesiones agudas inmediatas que puedan producir. Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally.

Thelong-term consequences for these children range from adverse effects on its psycholigical development to psychological, psychiatric organic disoders. It is important to note that good speeches are not enough to achieve success if any intervention are not done correctly.

    Full Text Available Introducción. La enfermedad de Chagas y la leishmaniasis son patologías de gran importancia en salud pública debido a su alta frecuencia y amplia distribución en América Latina. El estudio de los animales reservorios es vital para una comprensión global de estas enfermedades. Objetivo. En el presente trabajo nos propusimos identificar parásitos de la familia Trypanosomatidae en animales silvestres con la finalidad de establecer posibles relaciones debidas a la coinfección. Materiales y métodos. En El Carrizal, un área rural del estado Mérida, Venezuela, entre julio de 1998 y febrero de 2000 se realizaron capturas sistemáticas de animales silvestres con la finalidad de poner en evidencia la presencia de parásitos pertenecientes a la familia Trypanosomatidae. Las capturas fueron realizadas con trampas caseras tipo Tomahawk, colocadas 15 noches por mes durante el periodo del estudio. A los animales capturados se les practicó punción cardiaca bajo anestesia para extracción de sangre con la cual se realizaron los siguientes estudios: examen en fresco, extendido para coloración con Giemsa y cultivo en agar-sangre. Se realizaron algunos xenodiagnósticos. Los aislamientos obtenidos por medio de cultivo se identificaron por medio de análisis de restricción e hibridación con sondas específicas. Resultados. Se capturaron y estudiaron 215 animales pertenecientes a tres especies: Rattus spp. (135, Sigmodon hispidus (73 y Didelphis marsupialis (7.

    Sucrose synthase (SUS; EC 2.4.1.13) plays important roles in sugar metabolism and abiotic stress response. But the genes encoding SUS in cucumber (Cucumis sativus L.) have not been well studied. Here, we isolated four cucumber sucrose synthase genes (CsSUS). Among them, CsSUS3, which highly expressed in the roots, was chosen for further study. Immunolocalization and subcellular localization analysis indicated that CsSUS3 localized in the cytosol and the plasma membrane, and mainly existed in the companion cells of phloem in the roots. When suffering hypoxia stress from flooding, CsSUS3 expression and SUS activity in roots increased, especially in the lateral roots; moreover, the soluble SUS activity increased clearly, but the membrane fraction hardly changed. Compared with the wild-type cucumbers, the transgenic lines with antisense expression of CsSUS3 were more sensitive to flooding. After 6 d of flooding, the SUS activity, soluble sugar and uridine 5'-diphosphate glucose (UDPG) content and the ratio of ATP/ADP in the roots of transgenic plants were significantly lower than that in wild-type plants. Moreover, the transgenic lines grew more slowly with more yellow necrosis in the leaves. These findings suggested CsSUS3 participated in resisting hypoxic stress. Furthermore, the mechanism of CsSUS3 in resisting hypoxic stress was also discussed. © 2013 John Wiley & Sons Ltd.

Conclusión: Las enfermedades por anisakis y su consideración como enfermedad profesional, viene sujeta a la propia definición de lo que se considera así en nuestra norma legal, es decir que sea una enfermedad contraída como consecuencia del trabajo, en las actividades que se describen en el cuadro de enfermedades profesionales y por la acción del agente o sus sustancias que se recogen en el anexo I del actual cuadro. Además para que se admita como enfermedad profesional debemos de tener un diagnóstico firme (encuadrado en el cuadro de enfermedad profesional, un agente causal (recogido en el listado y una exposición al anisakis desarrollada en el ejercicio del trabajo (actividades recogidas en el listado. El listado o cuadro de enfermedad profesional es un sistema cerrado para agentes causales y enfermedades causadas, y la adscripción no es fácil. La parasitación tendría cabida en el grupo de enfermedades por agentes biológicos, la alergia podría discutirse su adscripción pero suele recogerse también en este grupo, el asma lo recogeríamos en el grupo de enfermedades respiratorias (causadas por inhalación dice el texto legal y las manifestaciones dérmicas en el grupo de las enfermedades profesionales de la piel. La exposición laboral al anisakis, es necesaria e imprescindible para que el proceso sea calificado de enfermedad profesional, pero esta exposición no siempre estará bien delimitada, y sin embargo debe estar probada. Puede haber existido una sensibilización fuera del trabajo y una aparición o desarrollo de la enfermedad por reiterada exposición o contacto con el anisakis en el trabajo lo que dificultará su calificación ocupacional.

    Full Text Available El Perú es el principal abastecedor de “tara”, gracias a que nuestro país posee una gran variedad de climas y tipos de suelos, haciendo posible la obtención de este cultivo durante la mayor parte del año. El departamento de Junín cuenta con poblaciones naturales de “tara” que aun no han sido caracterizadas bioquímica ni genéticamente, que podrían aprovecharse en beneficio de las comunidades locales. En este trabajo se reporta la capacidad antioxidante de “tara” provenientes de las localidades de Picoy y Santa Fe, ambas ubicadas en Tarma, Junín. Se utilizó la técnica del DPPH y del ABTS para valorar la capacidad antioxidante; para la determinación de fenoles y flavonoides se utilizó el reactivo de Folin-Ciocalteau según la técnica de Singleton. La muestra de Picoy reportó mayor cantidad de fenoles siendo de 563.70 mg/g de extracto seco, mientras que la cantidad de flavonoides fue de 0.664 mg/g. La capacidad antioxidante mostro una mejor respuesta en la muestra de Picoy, reportándose mediante el DPPH un IC50 1.244 mg/ml y con el ABTS un 35.3% de inhibición. Estos datos podrían aprovecharse para incrementar el valor agregado y mejorar la oferta de este recurso en dicha localidad debido a sus mejores características antioxidantes.

    Full Text Available El parvovirus canino tipo 2 (CPV-2 es el agente causal de una enfermedad infecto-contagiosa que produce una gastroenteritis aguda hemorrágica que afecta a caninos jóvenes. El CPV-2 se adaptó a la especie canina por mutación del virus de la Panleucopenia felina (FPV luego de su paso por animales silvestres como el hurón y los zorros. La alta variabilidad de la proteína viral 2 (VP2 es la causa principal del amplio rango de hospedadores y de las reacciones cruzadas entre las variantes. En la actualidad, la secuenciación de esta proteína ha permitido identificar tres variantes del virus conocidas como 2a, 2b y 2c que conviven en el mundo con diferencias en tropismo celular, infecciocidad y patogenicidad. El virus ssADN ha presentado una gran variación génica en cortos períodos de tiempo lo que indica un alto grado de selección por evolución sólo comparable con virus RN, esta alta variabilidad no se ha aclarado totalmente. El empleo de las técnicas moleculares permitirá diferenciar entre cepas vacunales y de campo, tanto como contar con técnicas diagnósticas confiables y específicas.

    Full Text Available Considerando que la Colonia Rivadavia se fundó en 1862, con el objetivo principal de aprovechar los pastizales del Chaco Semiárido para exportar ganado al Norte de Chile, analizamos desde una perspectiva histórica y demográfica, la relación existente entre las migraciones humanas y las principales actividades económicas del Departamento Rivadavia. Usando el método residual, se calcularon los saldos migratorios entre los censos nacionales de población y vivienda de 1914, 1947, 1960, 1970, 1980, 1991 y la población proyectada a 1998, resultando todos negativos. La expulsión constante de población, obedece al retroceso de la actividad ganadera por sobrepastoreo, lo que condujo a la degradación del ecosistema y la caída del ingreso, induciendo a los pobladores locales a presionar mas sobre el bosque y la fauna silvestre. La pobreza, consecuencia directa de un problema ambiental, obligó a emigrar de Rivadavia. Esta conclusión se sustenta en la evolución de distintos indicadores socio-económicos que se comparan para distintos períodos de los últimos treinta años: necesidades básicas insatisfechas, desnutrición infantil y el fracaso de distintos proyectos de desarrollo dirigidos principalmente a aborígenes en el período 1969 – 1992

    Full Text Available Population growth poses threats to biodiversity, specifically to sensitive species. Therefore, an understanding of the conflict between biodiversity and human population is needed to enable long-term planning of development and conservation policies by state and federal governments and society based on limitations and potentials of environments. We used a geopolitical approach to analyze data on human demography, economic activities, natural vegetation, avian diversity, and protected areas of the 32 states of Mexico and the 30 districts of the state of Oaxaca. Using factor analysis, we identified the biodiversity-rich geopolitical units that have a large human population and are developing intense economic activities. We then carried out a series of linear regressions between the resulting factors to test whether they were related, suggesting areas where conservation conflicts may exist, and found that relations between human activities and natural resources vary from region to region. These results help us identify geopolitical units that require detailed studies of the interactions between population and natural resources, and also highlight the importance of using geopolitical scales as study units, where most conservation and development policies are determined, to inform local stakeholders and decision makers.El crecimiento humano representa amenazas para la biodiversidad, especialmente para especies sensibles. Se necesita conocer a fondo el conflicto que representa el crecimiento de la población para la biodiversidad y llevar a cabo políticas y acciones a largo plazo de actividades de desarrollo y conservación evaluadas por gobiernos federales y estatales, basándose en las limitaciones y potenciales de los ecosistemas. Utilizamos una aproximación geopolítica para analizar variables de demografía humana, actividades económicas, superficie de vegetación, diversidad de aves y áreas protegidas de los 32 estados de México y los 30 distritos de Oaxaca. Mediante un análisis de factores, identificamos las entidades geopolíticas con más biodiversidad con alta población humana y que desarrollan intensamente actividades económicas. Posteriormente realizamos regresiones lineales entre los factores para analizar su interrelación, lo que sugiere áreas en las que la conservación está amenazada, encontrando que estas relaciones varían en cada región. Estos resultados identifican las unidades geopolíticas que requieren un estudio detallado de la interacción entre población y recursos naturales y resaltan la importancia de utilizar una escala geopolítica, que es el nivel donde se determinan la mayor parte de las políticas de conservación y desarrollo, para proveer información detallada a usuarios y tomadores de decisiones.

    Highlights: • Four SUS solutions are established to help reactors complete the start-up process. • Solutions C and D lead to superior behaved than Solutions A and B. • Solution C is fit for propulsion reactors and Solution D for nuclear power reactors. - Abstract: In this paper, we report on research that has been carried out both on the comparison and evaluation of four designed Start-up Systems (SUSs), which are proposed to improve reliability and economy during the reactor start-up process. Firstly, four SUS solutions are established to satisfy demands and detailed descriptions are introduced. Then, four reactor systems, which include SUS, are modeled by the estimate code JTopmeret. Furthermore besides, the JTopmeret code is validated for the once-through steam generators (OTSG). Finally, the behaviors of SUS and the steady and transient performance of OTSG are investigated. The results show that the designed SUS can successfully improve the economy and the OTSG operational safety. Suggestion is made in this paper to apply Solution C in propulsion-purposed reactors, and Solution D in nuclear power reactors

    Highlights: • The microstructure of F82H/SUS316L dissimilar joint can be divided into four regions. • In the case without beam position shift, hardness of WM cannot be reduced by PWHT. • The fiber laser welding would be applicable for constructing the dissimilar joint. -- Abstract: As one of the high beam quality heat sources, 4 kW fiber laser was applied for joining between reduced activation ferritic/martensitic steel, F82H and SUS316L austenitic stainless steel, and the microstructural analyses and Vickers hardness measurements were carried out before and after post-weld heat treatment (PWHT). The microstructure of joint can be divided into four regions which are base metal of F82H, heat affected zone (HAZ) in F82H, weld metal (WM) and base metal of SUS316L. Also, it is revealed that the high-power fiber laser can be employed for constructing butt joint between F82H and SUS316L by applying PWHT and shifting the laser beam position to SUS316L, where the distance between the contact face and beam should be set as a range from radius to diameter of laser beam.

The cavitation damage in Ni and austenitic stainless steel SUS304SS were studied by using an electro-Magnetic IMpact Testing Machine (MIMTM) developed to simulate the damage. The existence of dislocations, stacking fault tetrahedra and vacancies was detected by positron annihilation lifetime measurements in Ni, and non-cellular dislocation structures were observed by transmission electron microscopy in Ni and SUS304SS. In addition, a high density of twins was observed in SUS304SS. These results were compared with those of high-speed compression tests using a high-speed projectile, proving that the cavitation damage caused by MIMTM corresponded to high-speed deformation.

    Full Text Available Sucrose transport is the central system for the allocation of carbon resources in vascular plants. Sucrose synthase, which reversibly catalyzes sucrose synthesis and cleavage, represents a key enzyme in the control of the flow of carbon into starch biosynthesis. In the present study the genomic identification and characterization of the Sus2-2A and Sus2-2B genes coding for sucrose synthase in durum wheat (cultivars Ciccio and Svevo is reported. The genes were analyzed for their expression in different tissues and at different seed maturation stages, in four tetraploid wheat genotypes (Svevo, Ciccio, Primadur and 5-BIL42. The activity of the encoded proteins was evaluated by specific activity assays on endosperm extracts and their structure established by modelling approaches. The combined results of SUS2 expression and activity levels were then considered in the light of their possible involvement in starch yield.

    Full Text Available Es un hecho inédito en la historia de la humanidad que hijos que han llegado a la ancianidad cuiden de sus padres. Se mostrarán las particulares vicisitudes y desafíos que se plantean en el seno de la familia extensa cuando se trata de hijos adultos mayores quienes asumen la tarea de cuidar a sus padres, ya que éstas difieren de aquellas que se formulan cuando los hijos se encuentran en la adultez media. Si bien muchas familias se adaptan sin grandes sobresaltos a esta transición biográfica, otras se enfrentan a auténticas crisis. Distinguirlas puede ayudar a los profesionales de salud a manejar de mejor modo a sus pacientes y también ayudar a quienes se encuentran abocados a esta tarea.

    Título corto: Caracterización morfológica y evaluación de resistencia a Fusarium oxysporum Resumen:  Con el objetivo de evaluar la variación morfológica y la resistencia a Fusarium oxysporum en la colección del banco de germoplasma de la Universidad Nacional de Loja (UNL, 146 accesiones de cuatro especies silvestres fueron seleccionadas (Solanum pimpinellifolium, S. neorickii, S. habrochaites, S. lycopersicum var. cerasiforme; y, 20 accesiones de tomate cultivado (S. lycopersicum. Un total de 723 plántulas se transplantaron al campo y se evaluaron morfológicamente durante todo su ciclo biológico, con un descriptor que incluyó 20 caracteres cuantitativos y 25 cualitativos. Se estimó la variabilidad morfológica y se detectaron diferencias fenotípicas relacionadas con el fruto, características vegetativas de las plantas y los componentes del rendimiento. Las variables morfológicas mostraron que S. habrochaites es la especie más diferenciada con relación a las restantes. La podredumbre vascular causada por F. oxysporum es responsable de enormes pérdidas en la producción de tomate en el mundo; sin embargo, las especies silvestres que originaron las variedades cultivadas poseen genes de interés agronómico, utilizados por décadas para la generación de variedades resistentes. Por ello, entre 64 y 228 individuos por especie, se evaluaron por tres procedimientos de inoculación. Todas las especies fueron significativamente diferentes en los niveles de resistencia, tolerancia o susceptibilidad. S. neorickii fue más resistente y tolerante, seguida de S. pimpinellifolium y S. lycopersicum var. cerasiforme, mientras que todas las variedades cultivadas (S. lycopersicum fueron susceptibles. Tales circunstancias permitieron determinar sin lugar a dudas, que las plantas sobrevivientes y tolerantes poseen un genotipo particular que determina esa característica. Palabras clave:  Ecuador, tomate, tolerancia, susceptibilidad, inoculación. Abstract: In order

    Full Text Available The authors report the clinical, laboratorial and epidemiological aspects of a human case of jungle yellow fever. The patient suffered from fever, chills, sweating, headaches, backaches, myalgia, epigastric pains, nausea, vomiting, diarrhea and prostration. He was unvaccinated and had been working in areas where cases of jungle yellow fever had been confirmed. Investigations concerning the yellow fever virus were performed. Blood samples were collected on several days in the course of the illness. Three of these samples (those obtained on days 5,7 and 10 were inoculated into suckling mice in attempt to isolate virus and to titrate the viremia level. Serological surveys were carried out by using the IgM Antibodies Capture Enzyme Linked Immunosorbent Assay (MAC-ELISA, Complement Fixation (CF, Hemagglulinalion Inhibition (HI and Neutralization (N tests. The yellow fever virus, recovered from the two first samples and the virus titration, showed high level of viremia. After that, specific antibodies appeared in all samples. The interval between the end of the viremia and the appearance of the antibodies was associated with the worsening of clinical symptoms, including bleeding of the mucous membrane. One must be aware of the risk of having a urban epidemics in areas where Aedes aegypti is found in high infestation indexes.Os autores estudaram um caso humano de febre amarela silvestre, sob os aspectos clínico, laboratorial e epidemiológico.

Propusemos uma reflexão crítica sobre as condições de interação da prática de vigilância sanitária com uma proposição constitucional do SUS, a integralidade. Realizou-se uma análise baseada na Teoria da Estruturação, de Giddens, que considera a mobilização de recursos estruturais como uma dimensão de interação social que justifica a legitimação exercida pela sanção de normas. Foram ordenadas como categorias de análise: Visa e sua inserção no SUS; o princípio da integralidade e a Visa; e entraves políticos. A vigilância sanitária vem-se organizando a partir da Anvisa e atualmente assume novas responsabilidades sanitárias, entre elas a comunicação com a sociedade e ações de promoção da saúde. A discussão na literatura para a integralidade baseia-se no aspecto assistencial. A organização dos serviços nos diferentes entes federativos é o sentido de integralidade mais incorporado pela Visa. Os entraves políticos estão na renovação institucional, na arena de conflitos de interesses, na distância entre políticas formuladas e instituídas, e nas lacunas referentes à gestão do trabalho e à insuficiência do financiamento.The sanitary surveillance (Visa performs several practices, on different objects and its actions are guided by principles and guidelines of the SUS.

    Structural materials used in radiation environments require radiation tolerance and sufficient mechanical properties in the controlled state. In order to offer SUS316L austenitic stainless steel with the assumed requirements, nanostructured SUS316L with TiC addition of 2% (SUS316L-2TiC) that is capable of exhibiting enhanced tensile ductility and flow strength sufficient for structural applications was fabricated by advanced powder metallurgical methods. The methods include MA (Mechanical Alloying), HIP (Hot Isostatic Pressing), GSMM (Grain boundary Sliding Microstructural Modification) for ductility enhancement, cold rolling at temperatures below M d (the temperature where the martensite phase occurs by plastic deformation) for phase transformation from austenite to martensite and heat treatment for reverse transformation from martensite to austenite. It is shown that the developed SUS316L-2TiC exhibits ultrafine grains with sizes of 90–270 nm, accompanied by TiC precipitates with 20–50 nm in grain interior and 70–110 nm at grain boundaries, yield strengths of 1850 to 900 MPa, tensile strengths of 1920 to 1100 MPa and uniform elongations of 0.6–21%, respectively, depending on the heat treatment temperature after rolling at −196 °C. - Highlights: • Nanostructured SUS316L-2%TiC exhibiting sufficient tensile ductility and strength is developed. • The development requires an advanced powder metallurgical route. • The route includes MA, HIP, GSMM and thermo-mechanical treatments for phase transformation. • The austenite grain sizes are 90–270 nm and TiC precipitates 20–50 nm in grain interior. • The tensile strength are 1100–1920 MPa and uniform elongation 0.6–21%.
