    In a previous study, 18 repeated exposures of anaesthetized swine to an electro-muscular incapacitating device (TASER International's ADVANCED TASER X26 electronic control device) resulted in acidosis and increases in blood electrolytes. In the current study, experiments were performed to investigate effects of a more typical scenario of repeated exposures of the device on muscle contraction and changes in blood factors. Ten swine were exposed for 5s, followed by a 5-s period of no exposure, three times. Selected blood factors were monitored for 3h following exposure. Transient increases in blood glucose, lactate, sodium, potassium, calcium, and pCO(2) were consistent with previous reports in the literature dealing with studies of muscle stimulation or exercise. Blood pH was decreased immediately following exposure, but subsequently returned toward a normal level. Oxygen saturation (measured by pulse oximetry) was not changed significantly. In conclusion, three repeated TASER device exposures had only transient effects on blood factors, which all returned to pre-exposure levels, with the exception of hematocrit (which remained elevated after 3h). Since the increase in this factor was less than that which may occur after short periods of exercise, it is unlikely that this would be an indicator of any serious harm.

    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.

    The morphology of the hair cells of the inner ear end organs from the domestic pig (Sus scrofa) have been studied using a combination of Scanning and Transmission Electron Microscopy (SEM and TEM), revealing hair cells from the cochlea and vestibule using a novel surgical and technical approach. This is the first time that the inner ear hair cells from S. scrofa have been studied, thus providing useful anatomical information on the morphology of the hair cells from the cochlea, saccule and utricle from a large mammal. Anatomical information in relation to the morphology of the inner ear is of considerable importance, both in the pathological diagnosis of trauma and in the development of cochlea implants and other biotechnological systems associated with the enhancement of hearing. Standard fixation protocols using cardiac perfusion was not employed in this study as this method cannot always be applied, such as the pathological examination of the human ear, or the study of animals protected by endangered species legislation. With the exception of a very few countries, cetaceans cannot be killed for research purposes, yet physiological information on the inner ear from these species is urgently required for ecological assessment reasons. Supporting the use of S. scrofa as a model for cetacean hearing research is that this animal is a member of the order Artiodactyla, which includes both the hippopotamus and cetaceans. Being of a similar size, the pig is an ideal subject for developing protocols and surgical techniques required to investigate both the human and small cetacean auditory systems.

    Pig (Sus scrofa) is an important organism for both agricultural and medical purpose. This study aims to investigate the S. scrofa transcriptome by the use of Roche 454 pyrosequencing. We obtained a total of 558 743 and 528 260 reads for the back-leg muscle and ovary tissue each. The overall 1 087 003 reads give rise to 421 767 341 bp total residues averaging 388 bp per read. The de novo assemblies yielded 11 057 contigs and 60 270 singletons for the back-leg muscle, 12 204 contigs and 70 192 singletons for the ovary and 18 938 contigs and 102 361 singletons for combined tissues. The overall GC content of S. scrofa transcriptome is 42.3% for assembled contigs. Alternative splicing was found within 4394 contigs, giving rise to 1267 isogroups or genes. A total of 56 589 transcripts are involved in molecular function (40 916), biological process (38 563), cellular component (35 787) by further gene ontology analyses. Comparison analyses showed that 336 and 553 genes had significant higher expression in the back-leg muscle and ovary each. In addition, we obtained a total of 24 214 single-nucleotide polymorphisms and 11 928 simple sequence repeats. These results contribute to the understanding of the genetic makeup of S. scrofa transcriptome and provide useful information for functional genomic research in future.

    2017-08-01

    We identified a novel papillomavirus, Sus scrofa papillomavirus 2 (SsPV2), which is the first papillomavirus associated with papillomas in pigs. In skin alterations of a German wild boar, showing typical gross and histological appearance of papillomas, papillomavirus-like particles were demonstrated by electron microscopy. Degenerate papillomavirus-specific primers were used to amplify and sequence parts of the viral DNA. Subsequently, the complete genomic DNA was cloned and sequenced. The SsPV2 genome had a length of 8218 bp, encoded the early proteins E6, E7, E1 and E2, the late proteins L1 and L2 and contained an upstream regulatory region. Genomic characterization demonstrated papillomavirus-typical characteristics as well as unique features. For example, the E2 protein was significantly larger than in every other known papillomavirus species. Phylogenetic analysis was not able to relate SsPV2 unambiguously with other papillomavirus species or existing genera. Therefore, it might be representative of a new papillomavirus genus.

    Domestic and wild pigs, as intermediate hosts, can harbor tissue cysts of three Sarcocystis species namely S. miescheriana, S. suihominis and S. porcifelis. Out of them, S. suihominis is zoonotic. Romania is a country with high consumption of raw and/or undercooked traditional pork products. This fact may greatly favor the acquiring of the zoonotic Sarcocystis infections by humans, as definitive host. Based on this consideration and in order to investigate the occurrence and public health significance of Sarcocystis spp. in two western counties (Caraş-Severin and Timiş) of Romania, a total of 165 heart samples from hunted wild boars (Sus scrofa, n=101) and home slaughtered domestic pigs (Sus scrofa domesticus, n=64) were screened using microscopic fresh examination and molecular methods. Microscopic examination revealed the presence of sarcocysts in 60.4% of wild boars, and 23.4% of domestic pigs. Genetic characterization of isolates through the PCR-RFLP procedure, targeting the 18S rRNA gene, was successfully achieved for all microscopically positive samples, indicating the presence of a single species, S. miescheriana, in both hosts. The identity of 13 selected S. miescheriana isolates was also confirmed through sequencing. The tested hosts older than 27 months were found to be significantly higher infected (p<0.05) with Sarcocystis than the 6 to ≤27months age group. Although the human infective S. suihominis has not been registered, for a more reliable epidemiological picture, further molecular studies enrolling a larger number of animals and diagnosis on human intestinal Sarcocystis infections are still necessary.

    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.

    The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (>3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe.

    Between January and December 2013, the dental and periodontal health of 99 Swedish wild boars (Sus scrofa) was investigated. Sampling occurred in conjunction with routine hunting at six large estates in the southern and middle parts of Sweden. All six of the estates use supplemental feeding. The weight of the animals, their sex and their dates of death were noted. Age was estimated using tooth eruption and tooth replacement patterns. The oral cavity was inspected and abnormalities were recorded on a dental chart modified for wild boars. The findings included supernumerary teeth, absence of teeth, mild class II malocclusion, severe tooth wear, periodontitis, calculus, caries, tooth fractures and the presence of enamel defects. Swedish wild boars suffer from different dental lesions and the impact of supplemental feeding on dental and periodontal health is still to be investigated. Copyright © 2015 Elsevier Ltd.

    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.

    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 biology of sperm, its capability of fertilizing an egg and its role in sex ratio are the major biological questions in reproductive biology. To answer these question we integrated X and Y chromosome transcriptome across different species: Bos taurus and Sus scrofa and identified reproductive driver genes based on Weighted Gene Co-Expression Network Analysis (WGCNA) algorithm. Our strategy resulted in 11007 and 10445 unique genes consisting of 9 and 11 reproductive modules in Bos taurus and Sus scrofa, respectively. The consensus module calculation yields an overall 167 overlapped genes which were mapped to 846 DEGs in Bos taurus to finally get a list of 67 dual feature genes. We develop gene co-expression network of selected 67 genes that consists of 58 nodes (27 down-regulated and 31 up-regulated genes) enriched to 66 GO biological process (BP) including 6 GO annotations related to reproduction and two KEGG pathways. Moreover, we searched significantly related TF (ISRE, AP1FJ, RP58, CREL) and miRNAs (bta-miR-181a, bta-miR-17-5p, bta-miR-146b, bta-miR-146a) which targeted the genes in co-expression network. In addition we performed genetic analysis including phylogenetic, functional domain identification, epigenetic modifications, mutation analysis of the most important reproductive driver genes PRM1, PPP2R2B and PAFAH1B1 and finally performed a protein docking analysis to visualize their therapeutic and gene expression regulation ability.

    Limited information exists on Neospora caninum transmission dynamics in wildlife. This coccidian parasite, whose presence can lead to substantial economic losses in cattle operations, requires a canid definitive host for reproduction. We examined exposure in a definitive host, coyotes (Canis latrans), and in overlapping populations of feral swine (Sus scrofa) to determine if spatial proximity between a definitive and incidental host influences the likelihood of parasite exposure. Eighteen percent of coyotes (95% confidence interval [CI] = 14.2-21.8) and 15.8% of feral swine (95% CI = 12.5-19.2) had been exposed to N. caninum, and this is the first report of exposure in US feral swine populations. Analyses suggest that the parasite is present throughout the environment and that exposure is not temporally or spatially linked to antibody-positive coyotes. Antibody-positive feral swine were found in an area where the only definitive host is domestic dogs (Canis familiaris), indicating that wild canids are not required to maintain the parasite in the environment.

    :  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.

    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 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.

    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.

    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.

    Increasing food safety demands in the animal product market have created a need for a system to trace the food distribution process, from the manufacturer to the retailer, and genetic traceability is an effective method to trace the origin of animal products. In this study, we successfully achieved the farm tracing of 6,018 multi-breed pigs, using single nucleotide polymorphism (SNP) markers strictly selected through least absolute shrinkage and selection operator (LASSO) feature selection. We performed farm tracing of domesticated pig (Sus scrofa) from SNP markers and selected the most relevant features for accurate prediction. Considering multi-breed composition of our data, we performed feature selection using LASSO penalization on 4,002 SNPs that are shared between breeds, which also includes 179 SNPs with small between-breed difference. The 100 highest-scored features were extracted from iterative simulations and then evaluated using machine-leaning based classifiers. We selected 1,341 SNPs from over 45,000 SNPs through iterative LASSO feature selection, to minimize between-breed differences. We subsequently selected 100 highest-scored SNPs from iterative scoring, and observed high statistical measures in classification of breeding farms by cross-validation only using these SNPs. The study represents a successful application of LASSO feature selection on multi-breed pig SNP data to trace the farm information, which provides a valuable method and possibility for further researches on genetic traceability.

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    2016-04-01

    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.

    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.

    This study investigated and evaluated the safety margins of the continuous long duration (up to 30 min) effect of the TASER X26 waveform, using a Sus scrofa model. Long duration continuous stimulus has not been evaluated on humans or human surrogates prior to this study. Swine were used as models due to similarities with humans in their skin and cardiovascular systems. Very long duration was used to determine both exposure dose and possible adverse physiological effects of dose. The trial began with an application of 10 min, and subsequent animals received increasing exposure time up to a survived maximum duration of 30 min. At the onset of this work, it was hypothesized that there would be a time limit after which most animals would not survive consistent with increased dose response. However, this hypothesis was not supported by the experimental results. All animals (10 of 10) survived up to 3 min. Seven of the 10 animals survived up to a 10-min exposure and 3 of 5 animals with a 30-min target exposure survived the full exposure. Surviving animals were recovered and observed for 24 h, with no postrecovery deaths. This suggests that swine (based on physiology) will not experience a fatal event when exposed to the TASER X26 for a continuous 3 min. Conclusions regarding longer duration (10-30 min) are not as certain due to the small sample sizes at these time intervals. © 2013 American Academy of Forensic Sciences.

    Traumatic intrusion of incisor teeth occurs frequently in young children, as well as in teens and adults; however, the biological mechanisms promoting negative sequelae or recovery are not well understood (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009;107:493 and Vital Health Stat 11 2007;248:1). Modeling intrusive trauma and post-traumatic healing in an animal model offers the opportunity to define these biological mechanisms and to inform the design of treatments. The objective of this study was to investigate the pig, Sus scrofa, as a model for intrusive trauma, using an in vitro approach. Mandibular segments from ex vivo farm pigs were bisected and primary central incisors were prepared to either receive axial traumatic loads or to serve as non-intruded controls. A class 2 lever modeled traumatic impact to the incisors. Damage to the periodontal support in intruded and control specimens (n = 10) was evaluated through compression testing and comparison of elastic moduli. Incisor displacement was measured on X-ray images taken before and after trauma, and following compressive tests. Lingual x-rays showed a mean postinjury displacement of the incisor root of 3.81 ± 1.87 mm. With compression testing, the root length embedded in bone increased in traumatized and non-traumatized teeth by 2.9 mm and 0.81 mm, respectively (P = 0.03). The intrusion group Young's modulus was significantly lower than the control group (4452 vs 7704 Mpa; P = 0.05). In vitro modeling of traumatic intrusion resulted in damage to the periodontal support of central incisors and axial tooth displacement. Pig incisors offer an important model for further study of incisor trauma. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Laboratory animal regulations provide little guidance regarding duration of nonsurvival surgery requiring aseptic technique. We hypothesized that swine would experience no sepsis during nonsurvival cardiothoracic surgery accomplished by using clean technique and lasting 8 h or less. Incision sites of 5 male farm pigs (Sus scrofa) were shaved and then cleaned with alcohol and povidone-iodine. The surgeon wore sterile gloves, clean scrubs, and hair bonnet; assistants wore clean scrubs and nonsterile gloves; most instruments were autoclaved. A median sternotomy incision was used for thoracic cavity exposure, and the skull was exposed to allow induction of brain death. Heart rate, body temperature, and blood samples were obtained before surgery (0 h; baseline) and at 2, 4, 5 or 6, and 7 or 8 h thereafter. Statistical analysis by t-tests showed that heart rate was unchanged and body temperature increased after the 0-h (baseline) time point. Aerobic blood cultures were negative except for 2 samples that were positive for coagulase-negative Staphylococcus spp. at 4 h. RBC, Hgb, and Hct levels were decreased at 2 and 4 h, but WBC and platelets were unchanged. Other alterations included decreased glucose (at 7 or 8 h), increased BUN (at 5 or 6 h and 7 or 8 h) and creatinine (at 5 or 6 h), decreased Na(+) and Ca and increased K(+) (most time points), decreased total protein and albumin (most time points), and decreased globulin (at 7 or 8 h). Liver enzymes and bilirubin typically were unchanged, and cholesterol consistently was decreased. Together our results indicate a lack of sepsis for 8 h or less in pigs undergoing cardiothoracic surgery by using clean technique. These findings provide new and specific data regarding the use of aseptic technique during prolonged nonsurvival surgeries.

    Full Text Available Habitat use by wild boar Sus scrofaz was examined during a three-year period in Moncayo Nature Park, a protected mountain area in the Iberian mountain system, Spain. Tracking indirect signs of activity was used to collect data on the species occurrence, according to vegetation type, topography, hunting activity, and season. The data were analysed using binary logistic regression. Habitat used by wild boar differed according seasons, management practices, and vegetation. Main selected habitats were at medium elevations (1,101-1,600 m in areas dominated by holm oak (Quercus ilex, beech (Fagus sylvatica and oak woods of Q. robur, Q. petraea and Q. pyrenaica. Non-hunting areas were selected over hunting areas. We found a seasonal variation in the habitat use of wild boar, with areas dominated by holm oak being used disproportionately in spring, and areas at medium elevations selected only during summer. The results also support the view that non-hunting areas provide a refuge for this species inside the protected area.Estudiamos el uso del hábitat por parte del jabalí Sus scrofa a lo largo de tres años en el Parque Natural del Moncayo, un área protegida de montaña en el Sistema Ibérico, España.

    Trichinella spp. infections in wild boar (Sus scrofa), one of the main sources of human trichinellosis, continue to represent a public health problem. The detection of Trichinella spp. larvae in muscles of wild boar by digestion can prevent the occurrence of clinical trichinellosis in humans. However, the analytical sensitivity of digestion in the detection process is dependent on the quantity of tested muscle. Consequently, large quantities of muscle have to be digested to warrant surveillance programs, or more sensitive tests need to be employed. The use of indirect detection methods, such as the ELISA to detect Trichinella spp. infections in wild boar has limitations due to its low specificity. The aim of the study was to implement serological detection of anti-Trichinella spp. antibodies in meat juices from hunted wild boar for the surveillance of Trichinella spp. infections. Two tests were used, ELISA for the initial screening test, and a specific and sensitive Western blot (Wb) as a confirmatory test. The circulation of anti-Trichinella IgG was determined in hunted wild boar muscle juice samples in 9 provinces of 5 Italian regions. From 1,462 muscle fluid samples, 315 (21.5%, 95% C.I. 19.51-23.73) were tested positive by ELISA. The 315 ELISA-positive muscle fluid samples were further tested by Wb and 32 (10.1%, 95% C.I. 7.29-13.99) of these were positive with a final seroprevalence of 2.2% (95% C.I 1.55-3.07; 32/1,462). Trichinella britovi larvae were detected by artificial digestion in muscle tissues of one (0.07%, 95%C.I. 0.01-0.39) out of the 1,462 hunted wild boars. No Trichinella spp. larvae were detected in Wb-negative wild boar. From 2006 to 2012, a prevalence of 0.017% was detected by muscle digestion in wild boar hunted in the whole Italian territory. The combined use of both serological methods had a sensitivity 31.4 times higher than that of the digestion (32/1,462 versus 1/1,462), suggesting their potential use for the surveillance of the

    Full Text Available Aim: Identification of wild pig and domestic pig is essential to prevent illegal poaching of wild pig and to implement Wildlife (Protection Act, 1972. PCR-RFLP was used to differentiate Wild pig (Sus scrofa cristatus from Domestic pig (Sus scrofa domestica meat. Materials and Methods: DNA was isolated from meat samples of both the sub species and a fragment of Cytochrome b gene was amplified using universal primers and the PCR products were subjected to restriction digestion. Results: All the known samples of each of the sub-species amplified 474 bp fragment successfully using b1 and b2 primers. To differentiate between wild and domestic pig meat, restriction digestion of the PCR products was carried out to produce characteristic PCR-RFLP patterns for each species. StuI digestion yielded a RFLP pattern which distinguished the closely related sub species. The alignment of sequences of Wild pigs with sequences of local domestic pig, European wild pig and exotic breeds revealed 7 intra-species polymorphic sites within Cytochrome b gene fragment.Conclusion: This study showed that The PCR-RFLP is a simple and very effective tool for differentiating the samples of both the sub species and could prove to be a useful tool in forensic identification of wild pig and domestic pig.

    Full Text Available AbstractPorcine teschovirus (PTV, porcine sapelovirus (PSV, and enterovirus G (EV-G are infectious agents specific to pig host species that are endemically spread worldwide. This study aimed to investigate the natural infection by these porcine enteric picornaviruses in wild boars (Sus scrofa scrofa of Paraná state, Brazil, and to evaluate peccaries (Pecari tajacu and Tayassu pecari as alternative host species for these viruses. Fecal samples (n=36 from asymptomatic wild boars (n=22 with ages ranging from 2 to 7 months old (young, n=14 and 2 to 4 years old (adult, n=8 and from peccaries (6 to 8 months old, n=14 were collected from a farm and a zoo, respectively, both located in Paraná state. Reverse transcription-polymerase chain reaction (RT-PCR and nested-PCR (n-PCR assays targeting the 5'non-translated region of the virus genome were used for screening the viruses. Porcine enteric picornaviruses were detected in 12 out of the 22 wild boar fecal samples. According to each of the viruses, EV-G was most frequently (11/22, 50% detected, followed by PTV (10/22, 45.5% and PSV (4/22, 18.2%. Regarding the age groups, young wild boars were more frequently (9/14, 64.3% infected with PTV, PSV, and EV-G than adult animals (3/8, 37.4%. One n-PCR amplified product for each of the viruses was submitted to sequencing analysis and the nucleotide sequences were compared with the related viruses, which showed similarities varying from 97.7% to 100% for PTV, 92.4% to 96.2% for PSV, and 87.1% to 100% for EV-G. Peccaries tested negative for the viruses and in this study they did not represent infection reservoirs. This study is the first to report the molecular detection of PTV, PSV, and EV-G from captive wild boars in a South American country and the first to screen peccaries as alternative host species for porcine enteric picornavirus.

    A total 7 outbreaks of trichinellosis have occurred in Korea, mostly as a result of consumption of raw wild boar (Sus scrofa) meat. Since only 1 serological survey on wild boars had yet been performed in Korea, the present study aimed to estimate the prevalence of trichinellosis in wild boars and some species of rodents by artificial digestion and serological examinations in Yanggu-gun, Gangwon-do, the endemic area of trichinellosis. Both the wild boar and rodent muscle samples revealed no Trichinella larvae by direct examination and artificial digestion method. However, serological examinations revealed that 4 wild boar sera samples out of 118 (3.4%) were positive to Trichinella antigen. Although the recovery of Trichinella larvae ended in a failure, it is proved for the first time that the sylvatic cycle of Trichinella has been maintained in wild boars of Gangwon-do, Korea.

    Trichinellosis is a foodborne disease caused by the consumption of raw meat and raw meat-derived products from swine, horse and some game animals infected with nematode worms of the genus Trichinella. Between June 2006 and February 2011, 16 million domestic pigs and 0.22 million wild boars (Sus scrofa) were tested for Trichinella sp. in Hungary. Trichinella infection was not found in any pigs slaughtered for public consumption. Nevertheless, Trichinella spiralis was detected in four backyard pigs when trace back was done following a family outbreak. Trichinella infection was demonstrated in 17 wild boars (0.0077%). Larvae from wild boars were identified as Trichinella britovi (64.7%), T. spiralis (29.4%) and Trichinella pseudospiralis (5.9%). Although the prevalence of Trichinella sp. infection in wild boars and domestic pigs is very low, the spatial analysis reveals that the level of risk differs by region in Hungary. Most of the T. britovi infected wild boars (63.6%) were shot in the north-eastern mountain area of Hungary; whereas domestic pigs and wild boars infected with T. spiralis were detected only in the southern counties bordering Croatia and Romania. In the north-western and central counties, the prevalence of Trichinella infection seems to be negligible. Copyright © 2011 Elsevier B.V. All rights reserved.

    Full Text Available Aim: Wild boars, Sus scrofa, are potential reservoirs of many zoonotic diseases, and there are a possibility of transmission of the zoonotic diseases from these animals to humans and also domestic animals. This study aimed to evaluate the protozoan contamination of wild boars in the Persian Gulf’s coastal area (Bushehr Province, southwestern Iran. Materials and Methods: A total of 25 crossbred boars were collected during a course of vertebrate pest control in Bushehr province, in 2013. Samples were collected from the gastrointestinal tracts of each boar in 5% formalin, Bouin’s solution, sodium acetate-acetic acid-formalin, and polyvinyl alcohol fixatives. Fixed stool smears examined by trichrome and Ziehl–Neelsen staining. Results: Each of the 25 wild boars was infected with at least one of the intestinal protozoans. The rate of contamination with intestinal protozoan was 64% for Balantidium coli, 76% for Iodamoeba sp., 52% for Entamoeba polecki, 44% for Blastocystis sp. and 8% for Chilomastix sp. No intestinal coccidian was detected in studied boars when the stool samples were evaluated by Ziehl–Neelsen staining method. Conclusion: Findings of this study demonstrated that wild boars in the Persian Gulf coastal area are contaminated by many protozoans, including zoonotic protozoan, which poses a potential risk to locals as well as the domestic animals of the area.

  15. Encoding of situations in the vocal repertoire of piglets (Sus scrofa: a comparison of discrete and graded classifications.

    Directory of Open Access Journals (Sweden)

    Céline Tallet

    Full Text Available Two important questions in bioacoustics are whether vocal repertoires of animals are graded or discrete and how the vocal expressions are linked to the context of emission. Here we address these questions in an ungulate species. The vocal repertoire of young domestic pigs, Sus scrofa, was quantitatively described based on 1513 calls recorded in 11 situations. We described the acoustic quality of calls with 8 acoustic parameters. Based on these parameters, the k-means clustering method showed a possibility to distinguish either two or five clusters although the call types are rather blurred than strictly discrete. The division of the vocal repertoire of piglets into two call types has previously been used in many experimental studies into pig acoustic communication and the five call types correspond well to previously published partial repertoires in specific situations. Clear links exist between the type of situation, its putative valence, and the vocal expression in that situation. These links can be described adequately both with a set of quantitative acoustic variables and through categorisation into call types. The information about the situation of emission of the calls is encoded through five call types almost as accurately as through the full quantitative description.

    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).

    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.

    Leptospirosis is the most widespread zoonosis in humans worldwide. In the United States, widespread detection of antibodies to leptospirosis have been identified in feral swine (Sus scrofa) with the highest detection of serovars, Bratislava, Icterohaemorrhagiae, and Pomona. Over the past few years, feral swine populations have expanded their geographical range and distribution in the United States with reports in at least 39 of 50 states. Since feral swine serve as reservoirs for serovars that can infect humans, it is important to understand the risk of transmission. In order to learn more about the probability that feral swine shed infectious leptospires, we collected kidneys and paired serum when possible from 677 feral swine in 124 counties of 29 states. These counties had previously been identified as antibody positive for Leptospira interrogans serovars Bratislava, Canicola, Grippotyphosa, Hardjo, Icterohaemorrhagiae or Pomona. Although exposure to these same six serovars of leptospirosis continued to be high (53% overall) in the counties we sampled, we detected leptospiral DNA in only 3·4% of feral swine kidneys tested. Based on these results, it appears that although feral swine can serve as a source of infection to humans, especially in those who are more likely to encounter them directly such as wildlife biologists, veterinarians, and hunters, the risk may be relatively low. However, further studies to examine the relationship between leptospiral shedding in the urine and kidneys in addition to culturing the organism are recommended in order to better understand the risk associated with feral swine.

    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

    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.

    According to the coping styles hypothesis, an individual demonstrates an integrated behavioural and physiological response to environmental challenge that is consistent over time and across situations. Individual consistency in behavioural responses to challenge has been documented across the animal kingdom. Comparatively few studies, however, have examined inter-individual variation in the physiological response, namely glucocorticoid and catecholamine levels, the stress hormones secreted by the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, respectively. Variation in coping styles between individuals may be explained in part by differences in social rank and sex. Using 20 Yucatan minipigs (Sus scrofa) we: (1) investigated the existence of consistent inter-individual variation in exploratory behaviour and the hormonal stress response, and tested for correlations as predicted by the coping styles hypothesis; and (2) evaluated whether inter-individual behavioural and hormonal variation is related to social rank and sex. Salivary stress biomarkers (cortisol, alpha-amylase, chromogranin A) were assessed in the presence and absence of a stressor consisting of social isolation in a crate for 10 min. Principal components analysis on a set of behavioural variables revealed two traits, which we labelled exploratory tendency and neophobia. Neither exploratory tendency nor neophobia predicted the physiological stress response. Subordinate pigs exhibited higher catecholamine levels compared to dominant conspecifics. We observed sex differences in the repeatability of salivary stress markers and reactivity of the stress systems. The results do not provide support for the existence of behavioural-physiological coping styles in pigs. Sex is an important determinant of the physiological stress response and warrants consideration in research addressing behavioural and hormonal variation. Copyright © 2015 Elsevier Inc.

    Wild boar (Sus scrofa) populations are increasing in the Iberian Peninsula, and population management must include disease management and control. In this study, the epidemiology of 10 selected pathogens (Aujeszky's disease virus - ADV, porcine reproductive and respiratory syndrome virus - PRRSV, porcine influenza virus, porcine circovirus, porcine parvovirus, Erysipelotrix rhusiopathiae, Leptospira pomona, Chlamydia/Chlamydiaceae sp., Salmonella sp. and Mycobacterium bovis) in the wild boar population in Sierra Nevada National Park (SNNP), an open unfenced area, is reported, taking into account wild boar population abundance variation in space and time in an open unfenced environment. A total of 1103 wild boar were sampled in 141 hunting events randomly carried out for sampling in seven hunting seasons (October to February from 2002-2003 to 2009-2010 (except 2007-2008). Prevalence was overall lower than those previously reported for fenced wild boar populations in Spain, but all the pathogens analyzed except PRRSV were considered endemic in the SNNP. ADV, E. rhusiopathiae and total pathogen prevalence were positively correlated to wild boar density. Prevalence in the positive areas was significantly higher in females for ADV, E. rhusiopathiae, L. pomona, Chlamydia/Chlamydiaceae sp. and Salmonella sp., and in males for M. bovis. This longitudinal study provides the first data on the health status of the relatively unmanaged and low density wild boar population of SNNP. It is concluded that non-intensively managed wild boar populations are able to maintain the circulation of several pathogens, even in low prevalences and in open unfenced areas with natural density variation both in time and space.

    Full Text Available Trichinellosis is one of the most serious foodborne parasitic zoonoses in Europe. Wild carnivorous and omnivorous hosts are the main reservoirs of Trichinella spp. nematodes in nature. In the winter of 2008-2009, an atypical clinical case of trichinellosis occurred for the consumption of pork from a wild boar (Sus scrofa hunted in southwestern Alps in Italy. The symptomatic individual showed delayed development of oedemas in the lower limbs and eosinophilia, which appeared three months after infection. Muscle samples harboured 3.8 larvae/g, which were identified as Trichinella britovi. During the epidemiological investigation, anti-Trichinella IgG were detected in five hunters.

However, their use in non-human mammals is often hampered by the lack of Y-specific polymorphic markers. We identified new male-specific short tandem...... repeats (STRs) in Sus scrofa using the available genome sequence. We selected four polymorphic loci (5–10 alleles per locus), falling in one duplicated and two single-copy regions. A total of 32 haplotypes were found by screening 211 individuals from eight wild boar populations across Europe and five...

    The maternally inherited mitochondrial genome encodes key proteins of the electron transfer chain, which produces the vast majority of cellular ATP. Mitochondrial DNA (mtDNA) present in the mature oocyte acts as a template for all mtDNA that is replicated during development to meet the specific energy requirements of each tissue. Individuals that share a maternal lineage cluster into groupings known as mtDNA haplotypes. MtDNA haplotypes confer advantages and disadvantages to an organism and this affects its phenotype. In livestock, certain mtDNA haplotypes are associated with improved milk and meat quality, whilst, other species, mtDNA haplotypes have shown increased longevity, growth and susceptibility to diseases. In this work, we have set out to determine whether mtDNA haplotypes influence reproductive capacity. This has been undertaken using a pig model. To determine the genetic diversity of domestic pigs in Australia, we have sequenced the D-loop region of 368 pigs, and identified five mtDNA haplotypes (A to E). To assess reproductive capacity, we compared oocyte maturation, fertilization and development to blastocyst, and found that there were significant differences for maturation and fertilization amongst the haplotypes. We then determined that haplotypes C, D and E produced significantly larger litters. When we assessed the conversion of developmentally competent oocytes and their subsequent developmental stages to offspring, we found that haplotypes A and B had the lowest reproductive efficiencies. Amongst the mtDNA haplotypes, the number of mtDNA variants harbored at >25 % correlated with oocyte quality. MtDNA copy number for developmentally competent oocytes positively correlated with the level of the 16383delC variant. This variant is located in the conserved sequence box II, which is a regulatory region for mtDNA transcription and replication. We have identified five mtDNA haplotypes in Australian domestic pigs indicating that genetic diversity is

    Despite emergent research initiatives, significant knowledge gaps remain of soil microbiology-associated cadaver decomposition. Nevertheless, preliminary studies have shown that the vast diversity and complex interactions of soil microbial communities have great potential for forensic applications such as clandestine grave location and postmortem interval estimation. This study investigated changes in soil bacterial communities during pig (Sus scrofa domesticus) leg decomposition. 16S rRNA, instead of the usually applied 16S rDNA marker, was used to compare the metabolically active bacteria. Total bacterial RNA was extracted from soil samples of three different layers on day 3, 28 and 77 after the shallow burial of a pig leg. The V3 region of the 16S rRNA was amplified, analysed by RT-PCR DGGE, and compared with control soil bacterial community profiles. Statistically significant differences in soil bacterial biodiversity were observed. For the control, bacterial diversity (H') and species richness (S) of the three layers averaged 2.48±0.14 (H') and 18.8±2.5 (S), respectively, while for the test soil increases (p=0.027) were recorded between day 3 (H'=2.71±0.02; S=21.3±2.0) and 28 (H'=3.46±0.32; S=60.3±16.9), particularly in the middle (10-20 cm) and bottom (20-30 cm) soil layers. Between day 28 and 77 the diversity and richness then decreased on average for all three layers (H'=3.43±0.20; S=60.0±17.3) but remained higher than on day 3. Thus, responses in soil bacterial profiles and activity to carcass decomposition, detected and characterised by RNA-based DGGE, could be used together with RNA sequencing data, changes in physico-chemical variables (carbon, nitrogen, phosphorus, temperature, redox potential, water activity and pH) and conventional macroecology markers (e.g. insects and vegetation), to develop a suite of analytical protocols for different forensic scenarios.

    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

    Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that can induces gas gangrene or enteritis in poultry and humans and many other mammalian species. Here, we report an outbreak of C. perfringens type A and type C coinfection in wild boars ( Sus scrofa ). In February 2016, 10 dead wild boars, including two fresh carcasses, were found in Zhaosu County, Xinjiang Province, People's Republic of China. The two fresh carcasses were included in this study. Two strains of C. perfringens were isolated, identified, genotyped, and phylogenetically analyzed. Based on postmortem examination, bacterium isolation and identification, enterotoxin detection, and auxiliary tests, we made a diagnosis that the wild boar were killed by C. perfringens . Our findings provide the evidence that wild boar can be killed by C. perfringens intoxication. Wild boars are important reservoirs for many zoonotic agents. Therefore, more actions should be taken on the surveillance, prevention, and control of wild pig-borne diseases.

    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 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.

    In south-central Spain, the harvest of Eurasian wild boar (Sus scrofa) has increased significantly during recent decades in association with more intensive management actions to increase hunting yields and with consequent effects on the health status of the wild boar populations. We investigated the spatio-temporal trends and the risk factors related to the prevalence of Trichinella spp. in wild boar in order to obtain the annual probability of occurrence for these parasites in the Ciudad Real province of south-central Spain. Based on muscle samples collected during the hunting seasons from 1998/1999 to 2009/2010, the mean prevalence for Trichinella spp. in 95,070 wild boar was 0.2% (95% confidence interval 0.17-0.23). A subsample of 1,432 wild boar was also tested by ELISA. No correlation was observed between the prevalence of infection detected by serology and by the artificial digestion of muscle. The presence of Trichinella infections in wild boar showed a decreasing trend during the study period and was negatively related with fenced wild boar populations. The predicted 'favourability' for Trichinella infections disappeared almost completely after the 2006/2007 hunting season. Risk maps based on biogeographical tools showed, however, that most hunting estates presented favourable risk factors for these parasites during at least one of the hunting seasons studied.

    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.

    Laser fluorescence activated slit-scan flow cytometry offers an approach to a fast, quantitative characterization of chromosomes due to morphological features. It can be applied for screening of chromosomal abnormalities. We give a preliminary report on the development of the Heidelberg slit-scan flow cytometer. Time-resolved measurement of the fluorescence intensity along the chromosome axis can be registered simultaneously for two parameters when the chromosome axis can be registered simultaneously for two parameters when the chromosome passes perpendicularly through a narrowly focused laser beam combined by a detection slit in the image plane. So far automated data analysis has been performed off-line on a PC. In its final performance, the Heidelberg slit-scan flow cytometer will achieve on-line data analysis that allows an electro-acoustical sorting of chromosomes of interest. Interest is high in the agriculture field to study chromosome aberrations that influence the size of litters in pig (Sus scrofa domestica) breeding. Slit-scan measurements have been performed to characterize chromosomes of pigs; we present results for chromosome 1 and a translocation chromosome 6/15.

    In an earlier study, we found significant changes in red-blood-cell, leukocyte, and platelet counts, and in red-blood-cell membrane proteins, following exposures of anesthetized pigs to a conducted electrical weapon. In the current study, we examined potential changes in plasma proteins [analyzed via two-dimensional gel electrophoresis (2-DGE)] following two 30 s exposures of anesthetized pigs (Sus scrofa) to a TASER (®) C2 conducted electrical weapon. Patterns of proteins, separated by 2-DGE, were consistent and reproducible between animals and between times of sampling. We determined that the blood plasma collection, handling, storage, and processing techniques we used are suitable for swine blood. There were no statistically significant changes in plasma proteins following the conducted-electrical-weapon exposures. Overall gel patterns of fibrinogen were similar to results of other studies of both pigs and humans (in control settings, not exposed to conducted electrical weapons). The lack of significant changes in plasma proteins may be added to the body of evidence regarding relative safety of TASER C2 device exposures.

    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.

    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.

  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.

    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.

    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(13)C and δ(15)N 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.

    In previous studies hematocrit has been consistently increased in an anesthetized animal model after exposures to TASER(®) conducted energy weapons (CEWs). In the present study we analyzed changes in blood cell counts and red blood cell membrane proteins following two 30-s applications of a TASER C2 device (which is designed for civilian use). Hematocrit increased significantly from 33.2 ± 2.4 (mean ± SD) to 42.8 ± 4.6 % immediately after CEW exposure of eleven pigs (Sus scrofa). Red blood cell count increased significantly from 6.10 ± 0.55 × 10(12)/L to 7.45 ± 0.94 × 10(12)/L, and mean corpuscular volume increased significantly from 54.5 ± 2.4 fl to 57.8 ± 2.6 fl. Mean corpuscular hemoglobin concentration decreased significantly from 20.5 ± 0.7 to 18.5 ± 0.6 mM. Thirty protein spots (from two-dimensional sodium dodecyl sulfate polyacrylamide gel electrophoresis, selected for detailed comparison) exhibited greater densities 30-min post-exposure compared with pre-exposure values. A greater number of echinocytes were observed following CEW exposure. On the basis of these results it appears that, during the strong muscle contractions produced by TASER CEWs, a specific population of red blood cells (RBCs) may be released from the spleen or other reservoirs within the body. The total time of CEW exposure in the present study was relatively long compared with exposures in common law-enforcement scenarios. Despite statistically significant changes in red blood cell counts (and other measures directly related to RBCs), the alterations were short-lived. The transient nature of the changes would be likely to counteract any potentially detrimental effects.

    Porcine liver proteome iTRAQ analysis enabled the confident identification of 880 proteins with a rate of false positive identifications of less than 5%. Proteins involved in energy metabolism, catabolism, protein biosynthesis, electron transport, and other oxidoreductase reactions were highly enriched confirming the central role of liver as the major chemical and energy factory. Comparative analysis with human and mouse liver proteomes demonstrated that 80% of proteins were common to all three liver proteomes. In addition, it was also demonstrated that both sex of the animal and introduction of a novel phytase transgene into the genome each affected around 5% of total liver proteome. After controlling the false discovery rate (FDRonly four proteins (EPHX1, CAT, PAH, ST13) were shown to be differentially expressed between genders (Males/Females) and two proteins (SELENBP2, TAGLN) were differentially expressed between two lines (Transgenic/Conventional pigs). Current analysis is the largest proteome analysis for pig and complements the more extensive human and mouse proteome projects.

    This case represents the first case of Porcine Circovirus Type 2 (PCV-2)--infection in a free living European wild boar associated with morphological lesions, which are regarded as characteristic for Postweaning Multisystemic Wasting Syndrome (PMWS) in domestic pigs. The animal, an approximately 10 month old male, was found dead in a rural area within the state of Brandenburg, Germany. The closest commercial pig farm is located in 3 km distance from the spot where the carcass was found. At necropsy, the animal was found to be in a runted condition. Morphological investigation revealed two lesion complexes. Firstly, lymphatic depletion was present in different organs. Mainly the white pulp of the spleen was affected, where lymph follicles and periarteriolar lymphatic sheaths were nearly completely depleted of lymphoid cells. The former lymphatic areas could only be identified by the presence of histiocytic cells. Secondly, there were widely distributed lesions indicative of a bacterial septicemia i.e. purulent-necrotizing lymphadenitis, pulpous hyperplasia of the spleen, miliary lytic liver necroses and foci of fibrinous pneumonia. Within the lesions, bacterial colonies were found (short Gram-negative rods). Bacteriology revealed a septicemic Salmonella choleraesuis var. Kunzendorf--infection. Virologically, the animal was tested with negative results for Classical Swine Fever Virus and PRRSV. The unusual depletion of the lymphatic tissue mainly in the spleen led to the suspicion of a PCV-2 infection. Typical circoviral particles were found by negative-contrast electron microscopy in samples from spleen and lymph nodes. Using a commercial antiserum against Porcine Circovirus, positive staining was found by fluorescence microscopy in tonsils, spleen and lymph nodes. Finally, the virus was identified to be PCV-2 by species-specific PCR. The presented case rises the questions if PCV-2 is endemic in the European wild boar population at least in certain areas, if it is

    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 Trichinella spp. incidence in hunted wild boar and the number of snow cover days from 1976 to 1993. From 1997 to 2013, the estimated wild boar population of 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 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.

    Wild ungulates have greatly increased in abundance and range throughout Europe. This new situation presents a concern for public health because many wild ungulates are known reservoirs of zoonotic pathogens. In this work, we tested for the presence of the zoonotic pathogen Escherichia coli O157:H7 in free-ranging livestock and sympatric wild boars (Sus scrofa) and Iberian ibex (Capra pyrenaica) in NE Spain from 2009 to 2011. In addition, antimicrobial resistance and virulence factors were assessed. In total, individual fecal samples were obtained from 117 hunter-harvested wild boars and 160 Iberian ibexes. Fifty-five samples were obtained from cattle (5 herds, 380 animals in total) and four from the only horse herd in the Natural Park 'Ports de Tortosa i Beseit' (32 animals). Fecal samples were processed according to the ISO 16.654:2001 protocol to obtain E. coli O157 based on immunomagnetic separation. In addition, a multiplex polymerase chain reaction (PCR) targeting nine virulence factors characteristic of human pathotypes was performed. The prevalence was compared between host species with Fisher's exact test. Four wild boars (3.41%, 95% CI = 0.94-8.52) and two Iberian ibexes (1.25%, 95% CI = 0.15-4.4) carried E. coli O157:H7, which was not found in livestock feces (n = 59, 95% CI = 0-8.94). All E. coli O157:H7 isolates were susceptible to all antimicrobial agents tested. These results indicate that when prevalence in co-habiting livestock is low, wild ungulates do not seem to play an important role as reservoirs of E. coli O157:H7.

    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.

    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.

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.

    2013-06-01

    Wild boar is a species that is utilised for food and sport hunting throughout the world. Recent increases in natural populations and the potential of farming wild boars have stimulated interest in this species as a meat producer. Compared to domestic pigs, wild boars present a higher degree of carcass fatness and larger loin areas, more slow-twitch oxidative (I) and fast-twitch oxidative glycolytic (IIA) and less fast-twitch glycolytic (IIB) muscle fibres, and darker, less tender and leaner meat. Differences in diets might contribute to differences in cooked meat flavour and fatty acid composition between wild boars and domestic pigs. Higher α-tocopherol concentrations in wild boar might extend its meat shelf-life. Mechanical massaging of muscles, vacuum package ageing and addition of marinates have been attempted to tenderise wild boar meat. Further research on hunting protocols for wild boar, and value-added products from its meat, are needed. Copyright © 2013 Elsevier Ltd. All rights reserved.

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. The diet incorporates animals, plants and fungi. Among the latter two, both epigeal and hypogeal parts are consumed, together with fruits and seeds. Fungi and rhizomes of Gunnera tinctoria are the most abundant plant items in the diet. The wild boar in Chile forages chiefly in forested environments, but nonetheless the most frequent plant items in its diet are found in open spaces or outside the forest. Environments dominated by bamboos Chusquea spp. constitute important foraging sites. Rodents in the family Muridae prevail among animal items in the wild boar diet. This situation, however, is associated to the occurrence of a mouse outbreak (ratada resulting from the mast seeding of Chusquea spp. during our study. Birds in the family Rhinocryptidae together with invertebrates (specially Coleopteran larvae of Chiasognathus grantii made up a sizeable part of the animals in the wild boar diet.

    2014-11-01

    Intergranular stress corrosion cracking (IGSCC) in type SUS304 stainless steels, tested under pressurized water reactor (PWR) primary water conditions, has been characterized with unprecedented spatial resolution using scanning electron microscopy (SEM) and novel low-energy (∼3 kV) energy dispersive X-ray spectroscopy (EDX). An advancement of the large area silicon drift detector (SDD) has enhanced its sensitivity for X-rays in the low-energy part of the atomic spectrum. Therefore, it was possible to operate the SEM at lower accelerating voltages in order to reduce the interaction volume of the beam with the material and achieve higher spatial resolution and better signal-to-noise ratio. In addition to studying the oxide chemistry at the surface of intergranular stress corrosion cracks, the technique has proven capable of resolving Ni enrichment ahead of some crack tips. Active cracks could be distinguished from inactive ones due to the presence of oxides in the open crack and Ni-rich regions ahead of the crack tip. Furthermore, it has been established that SCC features can be better resolved with low-energy (3 kV) than high-energy (12 kV) EDX. The low effort in sample preparation, execution and data analysis makes SEM the ideal tool for initial characterization and selection of the most important SCC features such as dominant cracks and interesting crack tips, later to be studied by transmission electron microscopy (TEM) and atom probe tomography (APT).

    2016-01-01

    The traditionally cited recommendations for the preoperative restriction of food (including bedding) and water in pigs do not appear to be evidence-based. As a preliminary step in elucidating a rationale for and standardizing preoperative food and water restriction (PFWR), this structured review recorded recent reported practices in PFWR in laboratory pigs and its consequences. Medline, Google Scholar and Web of Science databases were searched for recently published (2012 – 2014) recovery surgery procedures in pigs. Information pertaining to PFWR practices, as delineated in the ARRIVE guidelines, was extracted from the 233 articles retrieved. Food withdrawal was described in 73 of the 233 (31%) papers evaluated, bedding withdrawal in 5 articles (2%), and water withholding in 13 publications (6%) papers. Food, bedding, and water withdrawal regimens had a median (range) duration of 12 (4 to 48), 48 (48 to 72), and 12 (2 to 12) h, respectively. Compared with other types of procedures, articles describing gastrointestinal or abdominal surgery were more likely to report fasting regimes. Liquid diets were described in 11 of the 233 (5%) publications evaluated. Adverse effects of PFWR effects were not reported. These data reveal considerable variation in PFWR practices. The stress of fasting coupled with the absence of evidence for current recommendations makes the rationale and standards for PFWR in pigs worthy of further study. PMID:26817978

    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.

    2017-01-01

    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.

    Supplementary feeding of ungulates, being widely used in game management, may have unwanted consequences. Its role in agricultural damage is well-studied, but few studies have considered the potential for the practice to attract ground nest predators. Our goal was to identify the factors influencing ground nest predation in the vicinity of year-round supplementary feeding sites for wild boar and to characterise their spatiotemporal scope. We conducted two separate artificial ground nest experiments in five different hunting districts in south-eastern Estonia. The quantity of food provided and distance of a nest from the feeding site were the most important factors determining predation risk. Larger quantities of food resulted in higher predation risk, while predation risk responded in a non-linear fashion to distance from the feeding site. Although predation risk eventually decreases if supplementary feeding is ceased for at least four years, recently abandoned feeding sites still pose a high predation risk.

    On 23 clinical healthy pigs (2-4 months of age, body weight 13-42 kg) under ketamin-pentobarbital anaesthesia blood plasma coagulation parameters have been investigated. To obtain basic values 26 parameters were measured: number of thrombocytes, parameters of thrombelastogram and resonance-thrombogram, prothrombin time, activated partial thromboplastin time, thrombin time, reptilase time, factors I, II, V, VII, VIII, X, antithrombin III, plasminogen, alpha 1-antitrypsin, alpha 2-antiplasmin, alpha 2-macroglobulin, fibrin degradation products D and E and euglobulin lysis-time. Parameters calculated in percent should be measured against a pig plasma pool. Measurement against a human plasma pool are hardly valid in values higher than 100%. In comparison to man the results indicate modifications of fibrinogenesis and fibrinolysis in pigs.

    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 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.

    Providing research pigs with enrichment objects can encourage species-typical behavior such as rooting and foraging. The authors gave pigs hard plastic 'foraging balls' that resembled enrichment devices commonly used for nonhuman primates. Holes were custom-drilled into the balls, and animal caretakers filled them with palatable food items such as jellybeans, unsalted peanuts, cereal, Beggin' Strips, primate biscuits and dog biscuits. Staff members suspended the balls from chains in pigs' enclosures, ensuring that toys did not touch the floor. All pigs manipulated the balls and were able to obtain treats that were supplemental to their standard diet. The simple and effective enrichment device was easily incorporated into the daily routines of research facilities, with little disruption to schedules.

    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.

    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

    2014-01-01

    Background Anaplasma phagocytophilum is a tick-borne pathogen of veterinary and human importance. Both ticks as vectors and vertebrates as reservoir hosts are essential for the cycle maintenance of this bacterium. Currently, the whole range of animal species reservoirs for A. phagocytophilum in natural environment is still unknown. Therefore, the aim of this study was to estimate the prevalence of infection with A. phagocytophilum in the wild boar population in southern Belgium. Results In the frame of a targeted surveillance program, 513 wild boars were sampled during the hunting season 2011. A nested 16S rRNA PCR was used to screen the presence of A. phagocytophilum DNA in spleen of boars. Within 513 samples, 5 (0,97%) were tested PCR positive and identification was confirmed by sequencing. Conclusions This study gives the first insight of presence of A. phagocytophilum in wild boars in southern Belgium. PMID:24694049

    Investigated the effect and mechanism of ascorbic acid on the development of porcine embryos produced by somatic cell nuclear transfer (SCNT). Porcine embryos were produced by SCNT and cultured in the presence or absence of ascorbic acid. Ten-eleven translocation 3 (TET3) in oocytes was knocked down by siRNA injection. After ascorbic acid treatment, reprogramming genes were analyzed by realtime reverse transcription-polymerase chain reaction (RT-PCR). Furthermore, relative 5-methylcytosine and 5-hydroxymethylcytosine content in pronucleus were detected by realtime PCR. Ascorbic acid significantly increased the development of porcine embryos produced by SCNT. After SCNT, transcript levels of reprogramming genes, Pou5f1 , Sox2 , and Klf were significantly increased in blastocysts. Furthermore, ascorbic acid reduced 5-methylcytosine content in pronuclear embryos compared with the control group. Knock down of TET3 in porcine oocytes significantly prevents the demethylation of somatic cell nucleus after SCNT, even if in the presence of ascorbic acid. Ascorbic acid enhanced the development of porcine SCNT embryos via the increased TET3 mediated demethylation of somatic nucleus.

    Constitutive humoral immunity (CHI) is thought to be a first-line of protection against pathogens invading vertebrate hosts. However, clear evidence that CHI correlates with host fitness in natural conditions is still lacking. This study explores the relationship between CHI, measured using a haemagglutination-haemolysis assay (HAHL), and resistance to classical swine fever virus (CSFV) among wild boar piglets. The individual dynamics of HAHL during piglet growth was analysed, using 423 serum samples from 92 piglets repeatedly captured in the absence of CSFV (in 2006) within two areas showing contrasting food availability. Natural antibody levels increased with age, but, in the youngest piglets antibody levels were higher in individuals from areas with the highest food availability. Complement activity depended on natural antibody levels and piglets' body condition. In the presence of CSFV (i.e., in 2005 within one area), serum samples from piglets that were repeatedly captured were used to assess whether piglet HAHL levels affected CSFV status at a later capture. The correlation between CHI and resistance to CSFV was tested using 79 HAHL measures from 23 piglets captured during a CSFV outbreak. Both natural antibodies and complement activity levels measured at a given time correlated negatively to the subsequent probability of becoming viremic. Finally, capture-mark-recapture models showed that piglets with medium/high average complement activity, independently of their age, were significantly less at risk of becoming viremic and more likely to develop a specific immune response than piglets with low complement activity. Additionally, piglets with high average complement activity showed the highest survival prospects. This study provides evidence linking CHI to individual fitness within a natural mammal population. The results also highlight the potential of HAHL assays to explore the dynamics and co-evolution between wildlife mammal hosts and blood-borne parasites interacting with the CHI. PMID:24260286

    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 surveys were conducted over the years 2013-2014. The biological material was represented by 43 females and 63 males, adults, with the age of over 3 years, harvested from three hunting grounds in Transylvania. Conformation measurements were made for the following characteristics: body length, height at the withers, the croup height, thorax perimeter, body weight, head length, forehead width between the ears. There were estimated average and dispersion factors for each characteristics and phenotypic correlations were estimated between concerned characteristics. There is a large variability in all studied characteristics, in both males and females, variability given by individual differences and higher performance limits for each characteristics, given by both individual variability and environmental condition and harvesting season.

    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.

    For the first time in the domestic pig, meiotic recombination along the 18 porcine autosomes was directly studied by immunolocalization of MLH1 protein. In total, 7,848 synaptonemal complexes from 436 spermatocytes were analyzed, and 13,969 recombination sites were mapped. Individual chromosomes for 113 of the 436 cells (representing 2,034 synaptonemal complexes) were identified by immunostaining and fluorescence in situ hybridization (FISH). The average total length of autosomal synaptonemal complexes per cell was 190.3 µm, with 32.0 recombination sites (crossovers), on average, per cell. The number of crossovers and the lengths of the autosomal synaptonemal complexes showed significant intra- (i.e. between cells) and inter-individual variations. The distributions of recombination sites within each chromosomal category were similar: crossovers in metacentric and submetacentric chromosomes were concentrated in the telomeric regions of the p- and q-arms, whereas two hotspots were located near the centromere and in the telomeric region of acrocentrics. Lack of MLH1 foci was mainly observed in the smaller chromosomes, particularly chromosome 18 (SSC18) and the sex chromosomes. All autosomes displayed positive interference, with a large variability between the chromosomes.

    Motor lateralization is hypothesized to depend on the complexity of the motor function, but it might at the same time reflect hemispheric dominance within an individual across motor functions. We investigated possible motor lateralization patterns in four motor functions of different complexity (snout use in a manipulative task, foot use in two-stepping tasks and tail curling) in the domestic pig, a tetrapod species relevant as farm animal but also as a model in human neuroscience. A significant majority of our sample showed individual biases for manipulation with their snout and for curling their tail. Interestingly, the tail curling was lateralized towards the right at the population level and showed stronger lateralization patterns than the snout. Using a cluster analysis with combined tail and snout laterality, we identified groups of individuals with different lateralization patterns across motor functions that potentially reflect the individuals' hemispheric dominance. To conclude, our results suggest that pigs show lateralization patterns that depend on the motor function and on the individual. Such individual lateralization patterns might have broader implications for animal personality and welfare. Our study lays the methodological groundwork for future research on laterality in pigs.

    Imprinted in placenta and liver (IPL) gene has been identified as an imprinted gene in the mouse and human. Its sequence and imprinting status, however, have not been determined in the domestic pigs. In the present study, a 259 base pair-specific sequence for IPL gene of the domestic pig was obtained and a novel SNP, a T/C transition, was identified in IPL exon 1. The C allele of this polymorphism was found to be the predominant allele in Landrace,Yorkshire, and Duroc. The frequency of CC genotype and C allele are different in Duroc as compared with Yorkshire (P = .038 and P = .005, resp.). Variable imprinting status of this gene was observed in different developmental stages. For example, it is imprinted in 1-day old newborns (expressed from the maternal allele), but imprinting was lost in 180-day-old adult (expressed from both parental alleles). Real-time PCR analysis showed the porcine IPL gene is expressed in all tested eight organ/tissues. The expression level was significantly higher in spleen, duodenum, lung, and bladder of 180-day-old Lantang adult compared to that in 1-day-old newborns Lantang pigs (P IPL gene is developmental stage and tissue specific.

    The objective of this study was to evaluate the effect of herbage allowance on pasture DM consumption by growing European wild boar. An additional objective was to evaluate the influence of pasture consumption on supplemental diet intake and BW gain. A previously sown grass-clover pasture was managed by cutting to obtain an herbage mass equivalent to 1,500 kg/ha DM. Areas of pasture were limited by fencing to obtain 3 different herbage allowances whereas the pasture was removed in other areas. Forty-eight purebred European wild boars (initial age of 120 d and initial BW of 14.4 kg) were grouped in pairs and each pair was randomly allotted to 1 of 4 treatments (6 pairs per treatment): no pasture (4 m(2); pasture removed), low (5.33 m(2); 400 g/d pasture DM available/wild boar), medium (8 m(2); 600 g/d pasture DM available/wild boar), and high (16 m(2); 1,200 g/d pasture DM available/wild boar). The treatment areas were moved daily with a 7-d rotation. For a 28-d period, wild boars entered their treatment areas from 0830 to 1630 h, after which they had free access to a supplemental diet for 1 h. Pasture consumption was estimated daily by cutting pasture samples pre- and postgrazing. Supplemental diet consumption was determined daily (feed offered minus remaining feed). Animals were weighed weekly. Pasture consumption differed (P allowances, respectively (P allowance, with the latter consumption being greater (P allowance treatments. The supplemental diet consumption tended (P = 0.16) to be less in wild boars with greater herbage allowance. European wild boars with access to pasture had greater (8.48 vs. 6.27 kg; P = 0.002) BW gain than those without access to pasture. In conclusion, pasture consumption by European wild boars can be enhanced by increasing herbage allowance and greater BW gains can be achieved in wild boars with access to pasture compared with those with no pasture access.

    We aimed to investigate the effect of chronic radiation exposure associated with the Fukushima Daiichi Nuclear Power Plant (FNPP) accident on the testes of boar and inobuta (a hybrid of Sus scrofa and Sus scrofa domestica). This study examined the contamination levels of radioactive caesium (Cs), especially (134)Cs and (137)Cs, in the testis of both boar and inobuta during 2012, after the Fukushima accident. Morphological analysis and electron-probe X-ray microanalysis (EPMA) were also undertaken on the testes. The (134)Cs and (137)Cs levels were 6430 ± 23 and 6820 ± 32 Bq/kg in the boar testes, and 755 ± 13 and 747 ± 17 Bq/kg in the inobuta testes, respectively. The internal and external exposure of total (134)Cs and (137)Cs in the boar testes were 47.1 mGy and 176.2 mGy, respectively, whereas in the inobuta testes, these levels were 6.09 mGy and 59.8 mGy, respectively. Defective spermatogenesis was not detected by the histochemical analysis of radiation-exposed testes for either animal. In neither animal were Cs molecules detected, using EPMA. In conclusion, we showed that adverse radiation-induced effects were not detected in the examined boar and inobuta testes following the chronic radiation exposure associated with the FNPP accident. © The Author 2016.

    Human settlement of Oceania marked the culmination of a global colonization process that began when humans first left Africa at least 90,000 years ago. The precise origins and dispersal routes of the Austronesian peoples and the associated Lapita culture remain contentious, and numerous disparate models of dispersal (based primarily on linguistic, genetic, and archeological data) have been proposed. Here, through the use of mtDNA from 781 modern and ancient Sus specimens, we provide evidence for an early human-mediated translocation of the Sulawesi warty pig (Sus celebensis) to Flores and Timor and two later separate human-mediated dispersals of domestic pig (Sus scrofa) through Island Southeast Asia into Oceania. Of the later dispersal routes, one is unequivocally associated with the Neolithic (Lapita) and later Polynesian migrations and links modern and archeological Javan, Sumatran, Wallacean, and Oceanic pigs with mainland Southeast Asian S. scrofa. Archeological and genetic evidence shows these pigs were certainly introduced to islands east of the Wallace Line, including New Guinea, and that so-called "wild" pigs within this region are most likely feral descendants of domestic pigs introduced by early agriculturalists. The other later pig dispersal links mainland East Asian pigs to western Micronesia, Taiwan, and the Philippines. These results provide important data with which to test current models for human dispersal in the region.

    The aim of this study was to examine the effects of litter size and parity on sibling competition, piglet survival, and weight gain. It was predicted that competition for teats would increase with increasing litter size, resulting in a higher mortality due to maternal infanticide (i.e., crushing) and starvation, thus keeping the number of surviving piglets constant. We predicted negative effects on weight gain with increasing litter size. Based on maternal investment theory, we also predicted that piglet mortality would be higher for litters born late in a sow's life and thus that the number of surviving piglets would be higher in early litters. As predicted, piglet mortality increased with increasing litter size both due to an increased proportion of crushed piglets, where most of them failed in the teat competition, and due to starvation caused by increased sibling competition, resulting in a constant number of survivors. Piglet weight at day 1 and growth until weaning also declined with increasing litter size. Sows in parity four had higher piglet mortality due to starvation, but the number of surviving piglets was not affected by parity. In conclusion, piglet mortality caused by maternal crushing of piglets, many of which had no teat success, and starvation caused by sibling competition, increased with increasing litter size for most sow parities. The constant number of surviving piglets at the time of weaning suggests that 10 to 11 piglets could be close to the upper limit that the domestic sow is capable of taking care of.

    Fresh samples of intestinal contents of three wild pigs originating from the Central Bohemia region were examined for the presence of bifidobacterial strains. During the study, we isolated many fructose-6-phosphate phosphoketolase-positive, strictly anaerobic, irregular rod-shaped bacterial isolates. Three of them were preliminarily identified as representing a novel species of the genus Bifidobacterium because their 16S rRNA gene sequence similarity with the closest relatives of thermophilic bifidobacteria (Bifidobacterium boum DSM 20432T, Bifidobacterium thermophilum DSM 20210T, Bifidobacterium thermacidophilumsubsp. porcinum LMG 21689T, Bifidobacterium thermacidophilumsubsp. thermacidophilum DSM 15837T) was in the range of 97.9 - 98.4 %. All three bacterial isolates had identical 16S rRNA, dnaJ1, fusA, gyrB and rplB gene sequences. Isolate RP115T was chosen as a representative of the bacterial group and DNA G+C content (mol%) determination, biochemical tests and analyses of physiological and morphological characteristics, habitat and chemotaxonomic traits (peptidoglycan structure, cellular fatty acids and polar lipids profile) were performed. The DNA-DNA hybridization analyses of RP115T and species representing the group of thermophilic bifidobacteria revealed values in the range from 33 to 53 %. This fact, together with relatively low sequence similarities of particular phylogenetic markers among examined bacterial strains and the phenotyping and chemotaxonomy results obtained, indicated that the evaluated bacterial isolate should be classified as representing a separate taxon within the specific group of thermophilic bifidobacteria. The name Bifidobacterium apri (of boar) sp. nov. has been proposed for the representative strain RP115T (=CCM 8605T=DSM 100238T=LMG 28779T).

    Diarrheal disease is the second leading cause of death in children younger than 5 y, and the most common cause of acute watery diarrhea in young children worldwide is rotaviral infection. Medicines to specifically reduce diarrhea would be a desirable adjunctive treatment to supportive fluid therapy to decrease the mortality rate of diarrheal diseases. In this study, we evaluated the efficacy of an antisecretory drug, racecadotril, in treating human rotavirus (HRV)-induced diarrhea in a neonatal gnotobiotic pig model. In total, 27 gnotobiotic pigs were randomly assigned (n = 9 per group) to receive either racecadotril, chlorpromazine (positive-control drug), or PBS (mock treatment) after inoculation with HRV. Pigs were weighed daily and rectal swabs were collected to determine fecal consistency scores and virus shedding. Rotaviral infection was confirmed by ELISA and cell culture immunofluorescence. Overall, the racecadotril-treated pigs had less severe illness than either the chlorpromazine- or mock-treated groups; this conclusion was supported by the lower fecal-consistency scores, shorter duration of diarrhea, and significant gain in body weight during the course of the study of the racecadotril-treated pigs. Through its influence on decreasing intestinal hypersecretion, racecadotril was better able to control the clinical signs of rotaviral infection in the gnotobiotic pigs. These results lend support for using racecadotril as a treatment for rotaviral diarrhea.

    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.

    In the European Union, various fluoroquinolones are authorised for the treatment of food producing animals. Each administration poses an increased risk of development and spread of antimicrobial resistance. The aim of this study was to investigate the impact of parenteral administration of enrofloxacin on the prevalence of enrofloxacin and ciprofloxacin susceptibilities in the commensal intestinal E. coli population. E. coli isolates from faeces of twelve healthy pigs were included. Six pigs were administered enrofloxacin on day 1 to 3 and after two weeks for further three days. The other pigs formed the control group. MIC values were determined. Virulence and resistance genes were detected by PCR. Phylogenetic grouping was performed by PCR. Enrofloxacin and ciprofloxacin were analysed in sedimentation samples by HPLC. Susceptibility shifts in commensal E. coli isolates were determined in both groups. Non-wildtype E. coli could be cultivated from two animals of the experimental group for the first time one week after the first administration and from one animal of the control group on day 28. The environmental load with enrofloxacin in sedimentation samples showed the highest amount between days one and five. The repeated parenteral administration of enrofloxacin to pigs resulted in rapidly increased MIC values (day 28: MIC up to 4 mg/L, day 35: MIC ≥ 32mg/L). E. coli populations of the control group in the same stable without direct contact to the experimental group were affected. The parenteral administration of enrofloxacin to piglets considerably reduced the number of the susceptible intestinal E. coli population which was replaced by E. coli strains with increased MIC values against enrofloxacin. Subsequently also pigs of the control were affected suggesting a transferability of strains from the experimental group through the environment to the control group especially as we could isolate the same PFGE strains from both pig groups and the environment.

    Full Text Available 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 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.

    Trichinella surveillance in wildlife relies on muscle digestion of large samples which are logistically difficult to store and transport in remote and tropical regions as well as labour-intensive to process. Serological methods such as enzyme-linked immunosorbent assays (ELISAs) offer rapid, cost-effective alternatives for surveillance but should be paired with additional tests because of the high false-positive rates encountered in wildlife. We investigated the utility of ELISAs coupled with Western blot (WB) in providing evidence of Trichinella exposure or infection in wild boar. Serum samples were collected from 673 wild boar from a high- and low-risk region for Trichinella introduction within mainland Australia, which is considered Trichinella-free. Sera were examined using both an 'in-house' and a commercially available indirect-ELISA that used excretory-secretory (E/S) antigens. Cut-off values for positive results were determined using sera from the low-risk population. All wild boar from the high-risk region (352) and 139/321 (43.3%) of the wild boar from the low-risk region were tested by artificial digestion. Testing by Western blot using E/S antigens, and a Trichinella-specific real-time PCR was also carried out on all ELISA-positive samples. The two ELISAs correctly classified all positive controls as well as one naturally infected wild boar from Gabba Island in the Torres Strait. In both the high- and low-risk populations, the ELISA results showed substantial agreement (k-value=0.66) that increased to very good (k-value=0.82) when WB-positive only samples were compared. The results of testing sera collected from the Australian mainland showed the Trichinella seroprevalence was 3.5% (95% C.I. 0.0-8.0) and 2.3% (95% C.I. 0.0-5.6) using the in-house and commercial ELISA coupled with WB respectively. These estimates were significantly higher (P<0.05) than the artificial digestion estimate of 0.0% (95% C.I. 0.0-1.1). Real-time PCR testing of muscle from seropositive animals did not detect Trichinella DNA in any mainland animals, but did reveal the presence of a second larvae-positive wild boar on Gabba Island, supporting its utility as an alternative, highly sensitive method in muscle examination. The serology results suggest Australian wildlife may have been exposed to Trichinella parasites. However, because of the possibility of non-specific reactions with other parasitic infections, more work using well-defined cohorts of positive and negative samples is required. Even if the specificity of the ELISAs is proven to be low, their ability to correctly classify the small number of true positive sera in this study indicates utility in screening wild boar populations for reactive sera which can be followed up with additional testing.

    Full Text Available Abstract Enzyme polymorphism at 42 loci was compared before and after a major epidemy of swine fever in wild boars from northern Vosges (France. No change was observed in the 38 monomorphic loci, but allele frequencies at the phosphoglucomutase locus PGM-2* changed significantly. Possible causes for this observation are discussed, and it appears that PGM-2 locus could be a genetic marker of resistance to this viral disease.

    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.

    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.

    It has been found that microRNAs (miRNAs) play important roles in the regulation of tooth development, and most likely increase the complexity of the genetic network, thus lead to greater complexity of teeth. But there has been no research about the key microRNAs associated with tooth morphogenesis based on miRNAs expression profiles. Compared to mice, the pig model has plentiful types of teeth, which is similar with the human dental pattern. Therefore, we used miniature pigs as large-animal models to investigate differentially expressed miRNAs expression during tooth morphogenesis in the early developmental stages of tooth germ. A custom-designed miRNA microarray with 742 miRNA gene probes was used to analyze the expression profiles of four types of teeth at three stages of tooth development. Of the 591 detectable miRNA transcripts, 212 miRNAs were continuously expressed in all types of tooth germ, but the numbers of miRNA transcript among the four different types of teeth at each embryonic stage were statistically significant differences (p < 0.01). The hierarchical clustering and principal component analysis results suggest that the miRNA expression was globally altered by types and temporal changes. By clustering analysis, we predicted 11 unique miRNA sequences that belong to mir-103 and mir-107, mir-133a and mir-133b, and mir-127 isomiR families. The results of real-time reverse-transcriptase PCR and in situ hybridization experiments revealed that five representative miRNAs may play important roles during different developmental stages of the incisor, canine, biscuspid, and molar, respectively. The present study indicated that these five miRNAs, including ssc-miR-103 and ssc-miR-107, ssc-miR-133a and ssc-miR-133b, and ssc-miR-127, may play key regulatory roles in different types of teeth during different stages and thus may play critical roles in tooth morphogenesis during early development in miniature pigs.

    We compare the efficacy of hydroxocobalamin to sodium thiosulfate to reverse the depressive effects on mean arterial pressure in a swine model of acute cyanide toxicity and gain a better understanding of the mechanism of action of the hydroxocobalamin in reversal of the toxicity. Swine were intubated, anesthetized, and instrumented with central arterial and venous lines and a pulmonary artery catheter. Animals (n=36) were randomly assigned to one of 3 groups: hydroxocobalamin alone (150 mg/kg), sodium thiosulfate alone (413 mg/kg), or hydroxocobalamin (150 mg/kg)+sodium thiosulfate (413 mg/kg) and monitored for 60 minutes after the start of antidotal infusion. Cyanide was infused until severe hypotension developed, defined as blood pressure 50% of baseline mean arterial pressure. Repeated-measures ANOVA was used to determine statistically significant changes between groups over time. Time to hypotension (25, 28, and 33 minutes), cyanide dose at hypotension (4.7, 5.0, and 5.6 mg/kg), and mean cyanide blood levels (3.2, 3.7, and 3.8 μg/mL) and lactate levels (7, 8.2, 8.3 and mmol/L) were similar. All 12 animals in the sodium thiosulfate group died compared with 2 of 12 in the hydroxocobalamin/sodium thiosulfate group and 1 of 12 in hydroxocobalamin group. No statistically significant differences were detected between the hydroxocobalamin and hydroxocobalamin/sodium thiosulfate groups for carbon monoxide, mean arterial pressure, cyanide levels, or mortality at 60 minutes. Lactate level (2.6 versus 2.1 mmol/L), pH (7.44 versus 7.42), and bicarbonate level (25 versus 26 mEq/L) at 60 minutes were also similar between groups. Sodium thiosulfate failed to reverse cyanide-induced shock in our swine model of severe cyanide toxicity. Further, sodium thiosulfate was not found to be effective when added to hydroxocobalamin in the treatment of cyanide-induced shock. Hydroxocobalamin alone was again found to be effective for severe cyanide toxicity. Copyright © 2012. Published by Mosby, Inc.

    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.

  13. Acidosis, lactate, electrolytes, muscle enzymes, and other factors in the blood of Sus scrofa following repeated TASER exposures.

    Repeated exposure to electro-muscular incapacitating devices could result in repetitive, sustained muscle contraction, with little or no muscle recovery period. Therefore, rhabdomyolysis and other physiological responses, including acidosis, hyperkalaemia, and altered levels of muscle enzymes in the blood, would be likely to occur. Experiments were performed to investigate effects of repeated exposures of TASER International's Advanced TASER X26 on muscle contraction and resultant changes in blood factors in an anaesthetized swine model. A total of 10 animals were used. Six swine were exposed for 5 s, followed by a 5-s period of no exposure, repeatedly for 3 min. (In five of the animals, after a 1-h delay, a second 3-min exposure period was added.) The remaining four animals were used for an additional pilot study. All four limbs of each animal exhibited contraction even though the electrodes were positioned in areas at some distances from the limbs. The degree of muscle contraction generated during the second exposure period was significantly lower than that in the first exposure series. This finding was consistent with previous studies showing that prolonged activity in skeletal muscle will eventually result in a decline of force production. There were some similarities in blood sample changes in the current experiments with previous studies of muscular exercise. Thus problems concerning biological effects of repeated TASER exposures may be related, not directly to the "electric output" per se, but rather to the resulting contraction of muscles (and related interruption of respiration) and subsequent sequelae. Transient increases in hematocrit, potassium, and sodium were consistent with previous reports in the literature dealing with studies of muscle stimulation or exercise. It is doubtful that these short-term elevations would have any serious health consequences in a healthy individual. Blood pH was significantly decreased for 1h following exposure, but subsequently returned toward a normal level. Leg muscle contractions and decreases in respiration each appeared to contribute to the acidosis. Lactate was highly elevated, with a slow return (time course greater than 1 h) to baseline. Other investigators have reported profound metabolic acidosis during restraint-associated cardiac arrest. Since restraint often occurs immediately after TASER exposure, this issue should be considered in further development of deployment concepts. On the basis of the results of the current studies, the repeated use of electro-muscular incapacitating devices in a short period of time is, at least, feasible, with the caveat that some medical monitoring of subjects may be required (to observe factors such as lactate and acidosis).

    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.

    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 work was to study some biochemical characteristics of crude alkaline protease extracts from the viscera of goby (Zosterisessor ophiocephalus), thornback ray (Raja clavata), and scorpionfish (Scorpaena scrofa), and to investigate their applications in the deproteinization of shrimp wastes. At least four caseinolytic proteases bands were observed in zymogram of each enzyme preparation. The optimum pH for enzymatic extracts activities of Z. ophiocephalus, R. clavata, and S. scrofa were 8.0-9.0, 8.0, and 10.0, respectively. Interestingly, all the enzyme preparations were highly stable over a wide range of pH from 6.0 to 11.0. The optimum temperatures for enzyme activity were 50°C for Z. ophiocephalus and R. clavata and 55°C for S. scrofa crude alkaline proteases. Proteolytic enzymes showed high stability towards non-ionic surfactants (5% Tween 20, Tween 80, and Triton X-100). In addition, crude proteases of S. scrofa, R. clavata, and Z. ophiocephalus were found to be highly stable towards oxidizing agents, retaining 100%, 70%, and 66%, respectively, of their initial activity after incubation for 1 h in the presence of 1% sodium perborate. They were, however, highly affected by the anionic surfactant SDS. The crude alkaline proteases were tested for the deproteinization of shrimp waste in the preparation of chitin. All proteases were found to be effective in the deproteinization of shrimp waste. The protein removals after 3 h of hydrolysis at 45°C with an enzyme/substrate ratio (E/S) of 10 were about 76%, 76%, and 80%, for Z. ophiocephalus, R. clavata, and S. scrofa crude proteases, respectively. These results suggest that enzymatic deproteinization of shrimp wastes by fish endogenous alkaline proteases could be applicable to the chitin production process. PMID:22312476

  5. Characteristics of wild boar (Sus scrofa habituation to urban areas in the Collserola Natural Park (Barcelona and comparison with other locations

    Directory of Open Access Journals (Sweden)

    Cahill, S.

    2012-01-01

    Full Text Available The parallel growth of urban areas and wild boar populations in recent years has increased the presence of this species around cities and in suburban areas, often leading to conflict with local people. In the Collserola Natural Park, situated within the metropolitan area of Barcelona, wild boar have become habituated to humans and urban settings because of direct feeding by local residents. Their attraction to these areas due to an abundance of anthropogenic food sources is especially strong during the warmer summer season when foraging conditions are poorer in their natural woodland habitat; the number of captures of habituated wild boar in peri–urban areas is significantly correlated with mean monthly temperatures. Habituated boar are primarily matriarchal groups, whereas adult and sub–adult (>1 year males are significantly less represented than in non–habituated boars. In Collserola, habituated sub–adult and adult females are significantly heavier than their non–habituated counterparts and these weight differences increase with age; in the > 3 year–old age class they may be 35% heavier. Conflicts generated by the presence of wild boar in peri–urban areas are complex, and the responses by authorities are similarly diverse and often exacerbated by ambivalent public attitudes, both towards wild boar presence and applied mitigation measures. By 2010, at least 44 cities in 15 countries had reported problems of some kind relating to the presence of wild boar or feral pigs.

    Multiple Trichinella species are reported from the Australasian region although mainland Australia has never confirmed an indigenous case of Trichinella infection in humans or animals. Wildlife surveys in high-risk regions are essential to truly determine the presence or absence of Trichinella, but in mainland Australia are largely lacking. In this study, a survey was conducted in wild pigs from mainland Australia's Cape York Peninsula and Torres Strait region for the presence of Trichinella, given the proximity of a Trichinella papuae reservoir in nearby PNG. We report the detection of a Trichinella infection in a pig from an Australian island in the Torres Strait, a narrow waterway that separates the islands of New Guinea and continental Australia. The larvae were characterised as T. papuae (Kikori strain) by PCR and sequence analysis. No Trichinella parasites were found in any pigs from the Cape York Peninsula. These results highlight the link the Torres Strait may play in providing a passage for introduction of Trichinella parasites from the Australasian region to the Australian mainland.

  7. A Review of the Current Status of Relevant Zoonotic Pathogens in Wild Swine (Sus scrofa) Populations: Changes Modulating the Risk of Transmission to Humans.

    2017-02-01

    Many wild swine populations in different parts of the World have experienced an unprecedented demographic explosion that may result in increased exposure of humans to wild swine zoonotic pathogens. Interactions between humans and wild swine leading to pathogen transmission could come from different ways, being hunters and game professionals the most exposed to acquiring infections from wild swine. However, increasing human settlements in semi-natural areas, outdoor activities, socio-economic changes and food habits may increase the rate of exposure to wild swine zoonotic pathogens and to potentially emerging pathogens from wild swine. Frequent and increasing contact rate between humans and wild swine points to an increasing chance of zoonotic pathogens arising from wild swine to be transmitted to humans. Whether this frequent contact could lead to new zoonotic pathogens emerging from wild swine to cause human epidemics or emerging disease outbreaks is difficult to predict, and assessment should be based on thorough epidemiologic surveillance. Additionally, several gaps in knowledge on wild swine global population dynamics trends and wild swine-zoonotic pathogen interactions should be addressed to correctly assess the potential role of wild swine in the emergence of diseases in humans. In this work, viruses such as hepatitis E virus, Japanese encephalitis virus, Influenza virus and Nipah virus, and bacteria such as Salmonella spp., Shiga toxin-producing Escherichia coli, Campylobacter spp. and Leptospira spp. have been identified as the most prone to be transmitted from wild swine to humans on the basis of geographic spread in wild swine populations worldwide, pathogen circulation rates in wild swine populations, wild swine population trends in endemic areas, susceptibility of humans to infection, transmissibility from wild swine to humans and existing evidence of wild swine-human transmission events. © 2015 Blackwell Verlag GmbH.

    The small diameter of temporary vascular shunts for vascular trauma management may restrict flow and result in ischemia or early thrombosis. We have previously reported a clinical experience with direct, open surgical reconstruction using expanded polytetrafluoroethylene (ePTFE) stent grafts to create a "sutureless" anastomosis as an alternative to standard temporary vascular shunts. We sought to characterize patency and flow characteristics of these grafts compared to standard shunts in a survival model of porcine vascular injury. 12 Yorkshire-cross swine received a 2cm long near-circumferential defect in the bilateral iliac arteries. A14-French Argyle shunt was inserted into one randomly assigned artery, with a self-expanding ePTFE stent deployed in the other. At 72 hours, conduit patency was evaluated by angiography. Arterial flow measurements were obtained at baseline, immediately after intervention, and after 72 hours via direct measurement with perivascular flow meters. Blood pressure proximal and distal to the conduits and arterial samples for histopathology were obtained during the terminal procedure. Angiography revealed no difference in patency at 72 hours (P=1.0). While there was no difference in baseline arterial flow between arteries (P=0.63), the stent grafts demonstrated significantly improved blood flow compared to shunts both immediately after intervention (390±36mL/min vs 265±25mL/min, p=0.002) and at 72 hours (261±29mL/min vs 170±36mL/min, p=0.005). The pressure gradient across the shunts was greater than that of the stent grafts (11.5mmHg IQR[3-19] vs. 3mmHg IQR[3-5], p=0.013). The speed of deployment was similar between the two devices. Open "sutureless" direct site repair using commercially available stent grafts to treat vascular injury is a technically feasible strategy for damage control management of peripheral vascular injury and offers increased blood flow when compared to temporary shunts. Furthermore, stent grafts may offer improved durability to extend the window until definitive vascular repair. The combination of these traits may improve outcomes after vascular injury.

    This study investigated cortisol inactivation by 11beta-hydroxysteroid dehydrogenase (11beta HSD) enzymes in porcine granulosa cells from antral follicles at different developmental stages and in ovarian cysts. In granulosa cells, cortisol oxidation increased threefold with antral follicle diameter (P ovarian cysts exhibited significantly lower enzyme activities than cells from large antral follicles. Neither intact cells norcell homogenates displayed net 11-ketosteroid reductase activities. Since porcine follicular fluid (FF) from large antral follicles and ovarian cysts contains hydrophobic inhibitors of glucocorticoid metabolism by type 1 11beta HSD, this studyalso investigated whether levels of 11beta HSD inhibitors changed during follicle growth and could affect cortisol metabolism in granulosa cells. The extent of inhibition of 11beta HSD1 activity in rat kidney homogenates decreased progressively from 50 +/- 8% inhibition by FF from small antral follicles (P Cyst fluid inhibited 11beta HSD1 activity by 59 +/- 4% (P cyst fluid (45-75% inhibition, P ovarian cysts. Moreover, changes in ovarian cortisol metabolism are accompanied by corresponding changes in the levels of paracrine inhibitors of 11beta HSD1 within growing ovarian follicles and cysts, implicating cortisol in follicle growth and cyst development.

    Porcine brucellosis occurs in many countries where pigs are farmed, often representing an underrated problem. B. suis biovar 2 is the most common isolate in Europe, with high prevalence reported in wild boars in which it is generally isolated in the absence of gross lesions. In the last five years, we tested for Brucella spp. 389 lymph nodes of wild boars collected during hunting seasons or during necropsy procedures. In this paper, we describe the first case of isolation of B. suis biovar 2 from a wild boar aborted foetus, and we analyse the genomic relationships with B.suis biovar 2 strains isolated in the past five years in Abruzzi Region, Central Italy. The genetic fingerprint revealed that the isolates under study belong to the MLST ST16 and to the MLVA11 Gt 57, similar to the Central-Eastern European strains. Massive restocking (for hunting purpose) of wild boars from Eastern Europe have been done since 1950 in Italy contributing to the increasing of population size and distribution, as well as to the interbreeding between these foreign breeds and the local population. The contamination of pastures with infected material such as aborted wild boars foetuses can increase the risk of transmission of Brucella among wild and domestic animals. The contact of B. suis with domestic ruminants may also cause serological reactions to brucellosis serological testing, and even unapparent infection, thus hampering the efforts made in the brucellosis eradication campaign.

    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.

    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.

  7. Stage-specific differential gene expression profiling and functional network analysis during morphogenesis of diphyodont dentition in miniature pigs, Sus Scrofa

    Science.gov (United States)

    2014-01-01

    Background Our current knowledge of tooth development derives mainly from studies in mice, which have only one set of non-replaced teeth, compared with the diphyodont dentition in humans. The miniature pig is also diphyodont, making it a valuable alternative model for understanding human tooth development and replacement. However, little is known about gene expression and function during swine odontogenesis. The goal of this study is to undertake the survey of differential gene expression profiling and functional network analysis during morphogenesis of diphyodont dentition in miniature pigs. The identification of genes related to diphyodont development should lead to a better understanding of morphogenetic patterns and the mechanisms of diphyodont replacement in large animal models and humans. Results The temporal gene expression profiles during early diphyodont development in miniature pigs were detected with the Affymetrix Porcine GeneChip. The gene expression data were further evaluated by ANOVA as well as pathway and STC analyses. A total of 2,053 genes were detected with differential expression. Several signal pathways and 151 genes were then identified through the construction of pathway and signal networks. Conclusions The gene expression profiles indicated that spatio-temporal down-regulation patterns of gene expression were predominant; while, both dynamic activation and inhibition of pathways occurred during the morphogenesis of diphyodont dentition. Our study offers a mechanistic framework for understanding dynamic gene regulation of early diphyodont development and provides a molecular basis for studying teeth development, replacement, and regeneration in miniature pigs.

    Full Text Available Salmonella is distributed worldwide and is a pathogen of economic and public health importance. As a multi-host pathogen with a long environmental persistence, it is a suitable model for the study of wildlife-livestock interactions. In this work, we aim to explore the spill-over of Salmonella between free-ranging wild boar and livestock in a protected natural area in NE Spain and the presence of antimicrobial resistance. Salmonella prevalence, serotypes and diversity were compared between wild boars, sympatric cattle and wild boars from cattle-free areas. The effect of age, sex, cattle presence and cattle herd size on Salmonella probability of infection in wild boars was explored by means of Generalized Linear Models and a model selection based on the Akaike's Information Criterion. Prevalence was higher in wild boars co-habiting with cattle (35.67%, CI 95% 28.19-43.70 than in wild boar from cattle-free areas (17.54%, CI 95% 8.74-29.91. Probability of a wild boar being a Salmonella carrier increased with cattle herd size but decreased with the host age. Serotypes Meleagridis, Anatum and Othmarschen were isolated concurrently from cattle and sympatric wild boars. Apart from serotypes shared with cattle, wild boars appear to have their own serotypes, which are also found in wild boars from cattle-free areas (Enteritidis, Mikawasima, 4:b:- and 35:r:z35. Serotype richness (diversity was higher in wild boars co-habiting with cattle, but evenness was not altered by the introduction of serotypes from cattle. The finding of a S. Mbandaka strain resistant to sulfamethoxazole, streptomycin and chloramphenicol and a S. Enteritidis strain resistant to ciprofloxacin and nalidixic acid in wild boars is cause for public health concern.

    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.

    The use of water medications is a common practice in the US swine industry to treat and prevent infections in swine herds with minimal labor and without risk of needle breakage. There are concerns that FDA-approved withdrawal times (WDT) may be inadequate for several water medications when exporting pork products to countries where MRLs (maximum residue limits) are lower than US tolerance levels. In this study, withdrawal intervals (WDI) were estimated for pigs when dosed with tetracycline and sulfamethazine in water. The WDI were calculated using the FDA tolerance method (TLM) and a population-based pharmacokinetic method (PopPK). The estimated WDIs (14-16 days using TLM) were similar to the approved WDT of 15 days for sulfamethazine. However, the PopPK method extended WDIs for both sulfamethazine (19-20 days) and tetracycline (12 days) compared to the currently approved WDTs in the U.S. This study also identified potential differences in WDI between weanling and finisher pigs. In conclusion, the TLM may not always provide adequate WDT for foreign export markets especially when MRLs differ from tolerance levels approved for US markets. However, PopPK methods can provide conservative WDIs in situations with considerable variability in medication exposure such as with administration in water. Copyright © 2015 Elsevier Inc.

    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.

    A laser-surface melting method was studied with the aim of increasing resistance to intergranular corrosion of welded SUS 304 stainless steel. An Nd:YAG laser beam at a laser beam size of about 1 mm and power of 170 Wm was employed and the laser power density was varied to optimize the depth of the laser melted layers. The microstructures of TIG welded and laser-surface melted regions were measured via optical, scanning electron, and transmission electron microscopy. In addition, a comparative evaluation of the intergranular corrosion properties of as-TIG welded and as-LSM surfaces of the SUS 304 weld was carried out using a doubleloop electrochemical potentiodynamic reactivation(DL-EPR) polarization method in a 1 L aqueous solution of 0.5 M H2SO4 and 0.01 M KSCN. According to the test results, the maximum melted depth was obtained at a beam scan rate of 600 mm/min and laser power density of 20 J/mm2. The laser-surface melted (LSM) region was observed to have a very fine, homogenous, and cellular microstructure compared to that of the TIG welded region. Grain growth in the laser-surface melted region from the substrate occurred epitaxially. The absence of Cr depletion along the grain boundary in the LSM region, which would result in increased resistance to intergranular corrosion of the welded SUS 304, was confirmed using an energy dispersive X-ray spectroscope attached to the electron microscope.

As fontes dos dados foram o Sistema de Informação Hospitalar (SIH/SUS e de Comunicação de Internação Hospitalar (CIH referentes a 2006 e 2007. A identificação do indivíduo foi feita pelo método probabilístico de associações de registros (linkage e para a composição dos dados da internação aplicaram-se algoritmos de composição nos registros de cobranças e de comunicações das internações. Foram analisadas 12.391.990 internações com ao menos um dia de duração no ano de 2006. A natureza do método probabilístico que encerra certo grau de imprecisão, a adoção de parâmetros conservadores a fim de evitar a inclusão de falsos positivos, tanto quanto a subnotificação da CIH representam as possíveis limitações do estudo. O Sistema de Serviços Hospitalares no Brasil apresentou taxa de hospitalização de 5,6%, sendo 5,0% SUS e 1,6% não SUS, diferenciando-se segundo Unidade da Federação de ocorrência. Os dados das internações não financiadas pelo SUS coletados pela CIH agregam informações importantes para a análise da assistência hospitalar no país.

    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.

    2009-01-01

    Full Text Available Wild boar is a widespread and abundant species for which until now reliable and accuratepopulation estimates are still lacking. In this study, a method based on non-invasive genetic sampling appliedin a mark-recapture framework is tested. Faeces collected along line transects serve as DNA source. Aim ofthe study was to evaluate efficiency and practicability of the sampling design and to assess if a sample sizesufficient for reliable population estimation can be achieved. In a 12-day sampling trial which was conductedin winter 2006 and covered approx. 25 km², 4 persons collected 141 fresh wild boar faeces originating from74 different individuals. This sample size was below those recommended for non-invasive mark-recapturestudies. Population estimates calculated using program CAPTURE strongly differed between models. Eventhough the non-invasive approach worked in principle for wild boar, further research will have to focus onincreasing sample size while keeping cost and effort acceptable for a large scale application of the method.

    Aggression is a major source of social stress with negative effects on health and well-being, yet limited information is known about the molecular mechanisms mediating aggressive behavior in swine. Ractopamine (RAC) is a β-adrenoreceptor agonist that enhances growth but increases aggressive behaviors in female pigs. Thus, the effects of RAC, sex, and social rank on the mRNA abundance of genes encoding serotonin and dopamine receptors, and monoamine oxidase (MAO)-A in brains of sub-adult pigs were evaluated. Top dominant and bottom subordinate pigs (16/sex) in pens of 4 pigs were determined, and fed either the control or RAC diets. At day 31, their raphe nuclei (RN), amygdala (AMY), frontal cortex (FC), and hypothalamus (HYP) were dissected; relative mRNA abundance for 5-HT₁(B), 5-HT₂(A), 5-HT₂(B), and D₁ receptors, and MAO-A was determined by Q-RT-PCR and data subjected to multivariate linear mixed model analysis and Tukey post-hoc test. Expression of 5-HT₁(B) and MAO-A was suppressed in the AMY of female pigs; 5-HT₂(B) expression was also suppressed in the RN, FC and HYP of females and RN of dominant pigs (P brain of pigs, especially in females independent of social rank, may be mediating the inter-individual offensive aggression.

    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.

    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.

    Earlier studies demonstrated that forestomach herbivores are less insulin sensitive than monogastric omnivores. The present study was carried out to determine if different distribution patterns of the glucose transporters GLUT1 and GLUT4 may contribute to these different insulin sensitivities. Western blotting was used to measure GLUT1 and GLUT4 protein contents in oxidative (masseter, diaphragm) and glycolytic (longissimus lumborum, semitendinosus) skeletal muscle membranes of monogastric omnivores (rats and pigs), and of forestomach herbivores (cows, adult goats, goat kids, and camels). Muscles were characterized biochemically. Comparing red and white muscles, the isocitrate dehydrogenase (ICDH) activity was 1.5-15-times higher in oxidative muscles of all species, whereas lactate dehydrogenase (LDH) activity was 1.4-4.4-times higher in glycolytic muscles except in adult goats. GLUT4 levels were 1.5-6.3-times higher in oxidative muscles. GLUT1 levels were 2.2-8.3-times higher in glycolytic muscles in forestomach herbivores but not in monogastric animals. We conclude that GLUT1 may be the predominant glucose transporter in glycolytic muscles of ruminating animals. The GLUT1 distribution patterns were identical in adult and pre-ruminant goats, indicating that GLUT1 expression among these muscles is determined genetically. The high blood glucose levels of camels cited in literature may be due to an "NIDDM-like" impaired GLUT4 activity in skeletal muscle.

  3. Evolution of microstructure and mechanical properties of SUS430/C11000/SUS430 composites during the laser-forming process

    2017-09-01

    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.

A constatação básica desta re-visita é a atualidade, treze anos depois, da temática abordada. O texto discute os argumentos mais freqüentes contrários e favoráveis à vinculação orçamentária no âmbito do SUS. e os principais aspectos da CPMF, criada para incrementar recursos para a saúde e da EC n.º 29. Aborda, ainda as mudanças constitucionais e legais recentes, ocorridas nos campos tributário e previdenciário. Conclui que dificilmente haverá no Brasil um sistema de saúde universal, igualitário que ofereça atenção integral de qualidade, tal como nos países de welfare state consolidado, enquanto os segmentos sociais de maior capacidade de pressão resolverem suas necessidades de atendimento médico fora desse sistema. Contudo reconhece os avanços importantes presentes no desenvolvimento do SUS, o qual, a despeito de suas vicissitudes, tem permanecido à margem do main stream das reformas sanitárias internacionais de corte neoliberal.This is a revisit to an article published in the first issue of Saúde e Sociedade, in 1992, done by the author himself.

El presente artículo trata, más que nada, de establecer las razones de una crítica dirigida a los fundamentos mismos de la Psicología Positiva: la positividad y la cientificidad. Frente al marcado énfasis en los beneficios de los afectos positivos, los estudios muestran que los afectos negativos pueden ser tan positivos, como negativos pueden ser los afectos positivos. La positividad no está del lado positivo (porque no hay tal lado. Tocante a lo que la Psicología Positiva dice saber científicamente de la felicidad, no parece ser nada que no se supiera. Incluso las mejores teorías, como el modelo de actividad positiva y la teoría de la extensión-y-construcción impresionan por sus trivialidades según están plagadas de tautologías. Notable es también la falacia demostrada de la ratio de positividad. Finalmente, se plantea que la felicidad no es sostenible como principio de vida (su búsqueda no es universal ni lo mejor que hacer en la vida, ni como objeto científico, como no sea acosta de hipostasiar la experiencia subjetiva.

    Full Text Available Abstract: In Brazil, ever since colonization plants have been used as natural products; thus, the National Health Surveillance Agency has been establishing rules for herbal medicine regulation; in this light, 71 plant species were chosen and empirically used in the country to investigate their medicinal properties. 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 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 Greek philosophy developed three types of philosophical schools. The first one, represented by the Milesians, the Eleatics and partly the Aristotle’s Lyceum, understands the philosophical activity as a set of projects of investigation, not necessarily lacking of pragmatic interest, moved by desire to explain the phenomena. Next to their activities of investigation, many of these philosophers maintain a political activity within the framework of their own cities. The second type, represented by the Pythagoreans and the Academy of Plato, aims to reach the union between knowledge and political power. This proposal finds its better synthesis in the ideal of philosopher king. At the hellenistic period, the goal of philosophical schools would be to offer the cultivated and instructed man a particular way of life.La filosofía griega desarrolló tres tipos de escuelas filosóficas. El primero, representado por los milesios, los eleáticos y, en parte, el Liceo de Aristóteles, entiende la actividad filosófica como un conjunto de proyectos de investigación, no necesariamente carentes de interés pragmático, movidos por el deseo de explicar los fenómenos. Junto a sus actividades de investigación, muchos de estos filósofos mantienen una actividad política en el marco de las instituciones de sus propias ciudades. El segundo tipo, representado por los pitagóricos y la Academia platónica, se propone alcanzar la unión entre el saber y el poder. Esta propuesta halla su mejor síntesis en el ideal del filósofo rey. Finalmente, en la época helenística, las escuelas filosóficas se proponen sobre todo ofrecer un ideal de vida al hombre culto e instruido de su tiempo.

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.

    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.

    1984-04-01

    A piece of stainless steel 304 was thermal annealed either in a 60Co solution at 280°C, or in a He atmosphere at 300 or 600°C after being smeared with a 60Co solution. The depth profile of 60Co in SUS was determined with these samples, together with those sampled from the water cleaning system in the Japan Power Demonstration Reactor and those exposed to a high-temperature water ( ~ 280°C) circulating OWL-loop installed in the Japan Material Testing Reactor, in order to determine the apparent values of the volume and grain boundary diffusion constants. The results have been compared with those of the previous measurements on Ni, Cr, and Fe above 500°C. A consistency has been noticed between both results at 600°C, while the present values at 280 and 300°C are much larger than those expected from the extrapolation of the previous measurements. Although this inconsistency is ascribed to the contribution of the dislocation pipe diffusion at such a low temperature, an attempt has been made to apply the present values to estimate how deep 60Co would penetrate SUS—one of the main constructing materials of the primary cooling system—in the life time of a power reactor.

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.

    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.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. Some thesis originated in the Public Health area about the subject are debated, in the light of more recent Social Science's studies concerned the Brazilian unionism. It presents a documentary analysis for the case of the largest National Workers Organization, named CUT. The need to discuss the problem in distinct political and economic conjunctures of the country is pointed out.

    Full Text Available Analisamos o sistema de saúde brasileiro em perspectiva comparada. A migração de clientelas de renda média para operadoras pré-pagas privadas aproxima o caso brasileiro do norte-americano. 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. Middle income beneficiaries migration to pre-paid private insurance makes Brazilian case similar to United States. Public hospital services delivery shows an important retrenchment enhanced by demographic growth and new expectations due to constitutional definitions. Retrenchment is selective and concentrates on obstetric and clinic services and private for-profit services. To ensure equal access it is necessary to improve public spending; diminish out-of-pocket spending; develop organizational reforms; improve government capacity.

    Zhang, K. Y.; Pyoun, Y. S.; Cao, X. J.; Wu, B.; Murakami, R.

    The changing of materials surface properties method always was taken into improving the fatigue strength. In this paper, an ultrasonic nanocrystal surface modification(UNSM) technique was used on the SUS 304 stainless steel to form a nanostructured surface layer with different static load(70N, 90N, 110N, 130N) and the vibration strike number was about 20,000times/mm2. The untreated and different condition specimens fatigue strength was all tested by a dual-spindle rotating bending fatigue test machine. SPring-8(a large synchrotron radiation facility) was used to test the surface nanocrystallization components. The X-ray diffraction (XRD), the scanning electron microscopy (SEM), optical microscope and a micro-Vickers hardness tester (MVK-E3, Akashi) were separately used to get the surface residual stresses, fracture surface after fatigue testing, metallographic structure and the microhardness of the nanostructured surface layer. The result showed that martensite transformation took place on the surface of specimens, the surface residual stresses had only a small increase and some cracks occurred between the martensite layer and the austenite layer, but the fatigue strength of 90N improved 81%.

    – Ley primera. Que los Indios, que trabajan, en la Coca sean bien tratados, y no usen de ella en supersticiones y hechicerías.

    Full Text Available El presente artículo analiza la crisis estructural del capitalismo provocada por el estallido de la burbuja especulativa inmobiliaria en EEUU en 2007 y sus repercusiones. El presente fenómeno es el desenlace de una serie de procesos desencadenados en respuesta a la crisis de sobreacumulación del capital de los años setenta que generó, por un lado, las condiciones para el dominio del capital financiero y, por otro lado, una nueva frontera de acumulación del capital en el Este asiático, sobre todo en China. La crisis cuestiona la centralidad de la economía norteamericana, lo que no significa necesariamente el desplazamiento del centro hegemónico del capitalismo hacia Asia. Lo que aquí defendemos, es la idea de que nos dirigimos hacia un mundo multipolar. This article analyzes the structural crisis of capitalism that began when the speculative home mortgage bubble burst in the United States in 2007, and the repercussions of that phenomenon. The current crisis is the outcome of a series of processes unleashed as a result of the crisis of overaccumulation of capital in the 1970s, which generated, on the one hand, the conditions for financial capital’s dominance and, on the other, a new frontier for the accumulation of capital in East Asia, especially in China. The crisis calls into question the centrality of the North American economy, but that does not necessarily mean the shift of capitalism’s hegemonic center to Asia. Here we will argue that we are headed toward a multipolar world.

    Full Text Available A diferencia de las líneas limítrofes marcadas por hitos y mojones, las zonas fronterizas que involucran territorios de dos o más países han estado siempre sometidas a continuas reconfiguraciones más o menos espontáneas, no han sido directamente inducidas o reconocidas por los estados, dado que surgen de acuerdo a las interacciones locales. Desde inicios del siglo XXI, está en marcha un proceso de definición de zonas fronterizas a partir de la política de la Comunidad Andina sobre desarrollo e integración fronteriza, pero sus resultados han sido contradictorios. Aunque tales definiciones contienen avances conceptuales, éstos parecen estar desarticulados del debate sobre el sentido de las zonas fronterizas en la integración entre vecinos para hacerle frente a la globalización y su aplicación no logra conducir aún a procesos transfronterizos. En esa perspectiva, el texto analiza, primero, la cuestión fronteriza en la integración andina a partir del examen de las iniciativas locales, nacionales y binacionales, así como de las definiciones de la integración andina al respecto; luego, examina el proceso de conformación de las cinco Zonas de Integración Fronterizas (ZIF: Colombia-Ecuador, Ecuador- Perú, Colombia-Perú, Perú-Bolivia, Colombia-Venezuela; después, establece una mirada comparada de tales procesos que toma en consideración la delimitación de las ZIF y los actores que han participado, el contraste entre los amplios fines y criterios andinos, su restricción al aplicarlos en las ZIF definidas y los obstáculos que han dificultado el desarrollo de las ZIF acordadas. En las conclusiones se realiza un balance más amplio de los procesos analizados.

    A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

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 A vigilância sanitária atua através de práticas e objetos diversos e suas ações são orientadas pelos mesmos princípios e diretrizes do Sistema Único de Saúde (SUS. 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.

    2013-12-01

    Equity is one of the pillars of Brazil's Unified Health System (SUS). However, analysis of the scientific literature shows that the concept of equity is polysemic and open to many interpretations. The scope of this article is to identify the meanings conferred upon equity in the discourse of SUS managers. Semi-structured interviews were conducted with individuals in three municipalities in the state of Sao Paulo, namely Marília, São Carlos and Santos. The interviews were recorded, transcribed and organized using the Discourse of the Collective Subject method. In the analysis of the results, three core categories were identified: Treat everyone in an egalitarian manner; treat the unequal in an unequal manner, prioritizing the most needy in accordance with their social and economic status; and treating the unequal in an unequal manner, prioritizing specific groups in accordance with risk criteria. The managers acknowledge equity as being a SUS principle and seek prudent clinical and epidemiological criteria to justify their choices in allocating resources. There is a need for further research into the concept and operationalization of equity and the need to hear the other actors of SUS who are involved in the actions and are jointly responsible for decisions on healthcare.

    Full Text Available Actualmente dentro de la diversidad familiar, los hogares monoparentales con jefatura masculina constituyen un fenómeno emergente. Este tipo de hogares se conforman de manera particular y, a la vez, generan nuevos retos ante las transformaciones de la sociedad de hoy. El objetivo de este artículo es presentar algunos resultados de una investigación de corte cualitativo, realizada en Bogotá en el 2014, en la que se indagó a padres pertenecientes a hogares monoparentales con jefatura masculina sobre los cambios y los significados de lo que para ellos constituyen la paternidad y la masculinidad, a través de la aplicación de entrevistas en profundidad. En esta investigación se identificaron algunos significados de ser padre en cuanto a roles de proveedor económico, cuidador, agente de socialización y transmisor de valores y costumbres para sus hijos; además los padres entrevistados evidenciaron nuevas lecturas frente a experiencias del pasado en sus vidas, especialmente en lo que se refiere a la relación con sus propios progenitores. Los resultados de las entrevistas permitieron visibilizar un cuestionamiento sobre la masculinidad hegemónica en cuanto a la dinámica de las relaciones afectivas y la comunicación dentro del hogar, así como las redes de apoyo con las que cuentan. Se evidenció además una considerable modificación del estilo de vida de los padres, en cuanto a su dimensión profesional, laboral, social y de esparcimiento personal con sus amigos, que se adapta esencialmente a las necesidades de sus hijos*. La experiencia de la jefatura de un hogar monoparental ha llevado a los padres entrevistados a modificar el ejercicio de su masculinidad en lo que tiene que ver con su comunicación, sus relaciones, la manera de expresar el afecto y el desempeño cotidiano con sus hijos, aceptando el nuevo rol familiar, al asociarlo con la responsabilidad de la crianza y el cuidado de los mismos.

    Microfluidics, a field that has been well-established for several decades, has seen extensive applications in the areas of biology, chemistry, and medicine. However, it might be very hard to imagine how such soft microfluidic devices would be used in other areas, such as electronics, in which stiff, solid metals, insulators, and semiconductors have previously dominated. Very recently, things have radically changed. Taking advantage of native properties of microfluidics, advances in microfluidics-based electronics have shown great potential in numerous new appealing applications, e.g. bio-inspired devices, body-worn healthcare and medical sensing systems, and ergonomic units, in which conventional rigid, bulky electronics are facing insurmountable obstacles to fulfil the demand on comfortable user experience. Not only would the birth of microfluidic electronics contribute to both the microfluidics and electronics fields, but it may also shape the future of our daily life. Nevertheless, microfluidic electronics are still at a very early stage, and significant efforts in research and development are needed to advance this emerging field. The intention of this article is to review recent research outcomes in the field of microfluidic electronics, and address current technical challenges and issues. The outlook of future development in microfluidic electronic devices and systems, as well as new fabrication techniques, is also discussed. Moreover, the authors would like to inspire both the microfluidics and electronics communities to further exploit this newly-established field.

    Electron bifurcation is the recently recognized third mechanism of biological energy conservation. It simultaneously couples exergonic and endergonic oxidation-reduction reactions to circumvent thermodynamic barriers and minimize free energy loss. Little is known about the details of how electron bifurcating enzymes function, but specifics are beginning to emerge for several bifurcating enzymes. To date, those characterized contain a collection of redox cofactors including flavins and iron-sulfur clusters. Here we discuss the current understanding of bifurcating enzymes and the mechanistic features required to reversibly partition multiple electrons from a single redox site into exergonic and endergonic electron transfer paths.

    Paper is ubiquitous in everyday life and a truly low-cost substrate. The use of paper substrates could be extended even further, if electronic applications would be applied next to or below the printed graphics. However, applying electronics on paper is challenging. The paper surface is not only very rough compared to plastics, but is also porous. While this is detrimental for most electronic devices manufactured directly onto paper substrates, there are also approaches that are compatible with the rough and absorptive paper surface. In this review, recent advances and possibilities of these approaches are evaluated and the limitations of paper electronics are discussed. Copyright © 2011 WILEY-VCH Verlag GmbH & Co.

    Electronic voting technology is a two edged sword. It comes with many risks but brings also many benefits. Instead of flat out rejecting the technology as uncontrollably dangerous, we advocate in this paper a different technological angle that renders electronic elections trustworthy beyond...... the usual levels of doubt. We exploit the trust that voters currently have into the democratic process and model our techniques around that observation accordingly. In particular, we propose a technique of trace emitting computations to record the individual steps of an electronic voting machine...... for a posteriori validation on an acceptably small trusted computing base. Our technology enables us to prove that an electronic elections preserves the voter’s intent, assuming that the voting machine and the trace verifier are independent....

    The roots, stems, leaves, and vascular circuitry of higher plants are responsible for conveying the chemical signals that regulate growth and functions. From a certain perspective, these features are analogous to the contacts, interconnections, devices, and wires of discrete and integrated electronic circuits. Although many attempts have been made to augment plant function with electroactive materials, plants' "circuitry" has never been directly merged with electronics. We report analog and digital organic electronic circuits and devices manufactured in living plants. The four key components of a circuit have been achieved using the xylem, leaves, veins, and signals of the plant as the template and integral part of the circuit elements and functions. With integrated and distributed electronics in plants, one can envisage a range of applications including precision recording and regulation of physiology, energy harvesting from photosynthesis, and alternatives to genetic modification for plant optimization.

    Full Text Available En este trabajo se realiza un estudio sobre la responsabilidad penal del empresario por los actos al margen de la ley que cometen sus subordinados. Se busca aclarar si el empresario debe responder penalmente cuando el delito es cometido por un subordinado en ejercicio de sus funciones o cuando este actúa a nombre de la empresa ya sea valiéndose de la información que manejan, del grado de responsabilidad o de la confianza. Por esta razón concentraremos nuestra atención en analizar la responsabilidad penal por la omisión de controles del empresario hacia el subordinado, exponiendo la problemática que se deriva de la posición de garante del primero en las operaciones empresariales.

    Knop, Filip K; Holst, Jens Juul; Vilsbøll, Tina

    2008-01-01

    Type 2 diabetes mellitus (T2DM) is a progressive disease characterized by insulin resistance, a steady decline in glucose-induced insulin secretion (most likely caused by a progressive decrease in functional beta-cell mass), and inappropriately regulated glucagon secretion; in combination......, these effects result in hyperglycemia. In 1958, sulfonylurea (SU) was introduced to the market as one of the first oral treatments for T2DM. Since then, the ability of SU to stimulate the release of insulin from pancreatic beta-cells by the closure of ATP-sensitive K+-channels has been employed as one...... of the most widespread treatment options for T2DM. However, SUs are associated with weight gain and a risk of hypoglycemia, and the one-track antidiabetic mechanism of SUs often results in patients being treated with additional antidiabetic drugs. In recent studies, SU has proven to be associated...

  17. A homeopatia no SUS na perspectiva de estudantes da área da saúde

    Directory of Open Access Journals (Sweden)

    Gecioni Loch-Neckel

    Full Text Available A homeopatia foi reconhecida como especialidade médica em 1980. Após a criação do SUS, alguns estados e municípios brasileiros começaram a oferecer atendimento homeopático aos usuários dos serviços públicos de saúde. Em 2006, foi editada a Portaria 971, que assegura o acesso à homeopatia a estes usuários, entre outras práticas integrativas e complementares. Diante disto, investigamos as percepções de estudantes dos cursos de Farmácia, Medicina e Odontologia sobre a homeopatia e sua prática no SUS, tendo por fundamento a teoria das representações sociais. Estas representações foram construídas com os seguintes parâmetros: a homeopatia como terapêutica; a relação entre a homeopatia, o SUS e o princípio da integralidade. Os estudantes souberam correlacionar o atendimento integral ao sujeito à compreensão de suas necessidades a partir de sua realidade. Constatou-se desconhecimento sobre os pressupostos teóricos da homeopatia e o não reconhecimento da incorporação da homeopatia no SUS, para a maioria dos estudantes. Pode ser sugerido que a inserção dos futuros profissionais no contexto das atividades em saúde e o acesso a outras racionalidades permitiriam uma escolha mais lúcida de suas práticas profissionais.

    To investigate the outpatient access to nuclear medicine procedures by means of the Brazilian Unified Health System (SUS), analyzing the correspondence between data provided by this system and those from Comissão Nacional de Energia Nuclear (CNEN) (National Commission of Nuclear Energy). Data provided by Datasus regarding number of scintillation chambers, outpatient procedures performed from 2008 to 2012, administrative responsibility for such procedures, type of service providers and outsourced services were retrieved and evaluated. Also, such data were compared with those from institutions certified by CNEN. The present study demonstrated that the system still lacks maturity in terms of correct data input, particularly regarding equipment available. It was possible to list the most common procedures and check the growth of the specialty along the study period. Private centers are responsible for most of the procedures covered and reimbursed by SUS. However, many healthcare facilities are not certified by CNEN. Datasus provides relevant data for analysis as done in the present study, although some issues still require attention. The present study has quantitatively depicted the Brazilian reality regarding access to nuclear medicine procedures offered by/for SUS.

    Full Text Available SUS440 is a high-carbon stainless steel, and its martensite matrix has high heat resistance, high corrosion resistance, and high pressure resistance. It has been widely used in mechanical parts and critical materials. However, the SUS440 martempered matrix has reliability problems in thin plate applications and thus research uses different austempering heat treatments (tempering temperature: 200 °C–400 °C to obtain a matrix containing bainite, retained austenite, martensite, and the M7C3 phase to investigate the relationships between the resulting microstructure and tensile mechanical properties. Experimental data showed that the austempering conditions of the specimen affected the volume fraction of phases and distribution of carbides. After austenitizing heat treatment (1080 °C for 30 min, the austempering of the SUS440 thin plates was carried out at a salt-bath temperature 300 °C for 120 min and water quenching was then used to obtain the bainite matrix with fine carbides, with the resulting material having a higher tensile fracture strength and average hardness (HRA 76 makes it suitable for use as a high-strength thin plate for industrial applications.

    2010-11-01

    The sanitary surveillance (Visa) performs several practices, on different objects and its actions are guided by principles and guidelines of the SUS. It was done a critical reflection on the interaction conditions of practice in Visa, with a constitutional proposition of the SUS: integral care. The analysis was based on the theory of structuration (Giddens) that considers mobilization of structural resources as dimensions of social interaction, which would justify the legitimacy exercised since the standards. Have been analyzed the following categories: Visa and its insertion within the SUS; the integral care and the Visa; and political impediments. The Visa has been organized by National Health Surveillance Agency. Nowadays it has as sanitary responsibilities, communication with society and health promotion. The proposal of the literature concerning integral care is based on the assistance issue. The organization of the services in the different federative entities is the sense of integral care most adopted by Visa. Political impediments focus on the institutional renewal, on the conflicts of interest arena, on the distance between formulated policies and established practices and gaps concerning work management and the insufficiency of financial support.

    Full Text Available Los protestantes en sus múltiples denominaciones se han convertido en la segunda fuerza religiosa de Colombia gracias a su permanente proselitismo mediático y a su presencia en todos los escenarios sociales y políticos del país, un crecimiento que terminó por disputarle fieles al catolicismo tradicionalista. Con el ánimo de comprender su expansión y subdivisiones en la revisión historiográfica,se buscó describir y analizar el proceso histórico por medio del cual los protestantes en todas sus denominaciones lograron ampliar el campo religioso colombiano. Para ello,se consideró oportuno hacer una síntesis histórica, y en su narración explicar los principales conceptos que intentan definir el campo protestante. La investigación se basó en una revisión exhaustiva de la bibliografía existente sobre el protestantismo en Colombia y en una revisión documental sobre lo escrito por los protestantes y sus contradictores católicos. En las conclusiones se insiste en afirmar que los protestantes lograron crecer exponencialmente gracias a su fragmentación y posterior conformación en iglesias nacionales de talante carismático y pentecostal.

  5. De las perturbadoras y conflictivas relaciones de los bogotanos con sus aguas

    2007-01-01

    Full Text Available el propósito de este texto es dar cuenta de la desligación entre el ser y su estar, manifestado históricamente en la ciudad de Bogotá desde su fundación en 1538 hasta nuestros días. Las aguas son parte de ese estar en el territorio y genera formas de ser. La indiferencia y el abandono de los ríos expresado a través de la contaminación, entubamiento, y sus consecuencias: inundaciones, olores fétidos, desbordes, escasez, son imágenes que no contribuyen a construir ese ser a partir del estar en el territorio. Para rastrear esta desligación entre los bogotanos y sus cuarenta y nueve corrientes de agua, presentamos los momentos claves de esta relación, desde la concepción poética del agua que crearon los primeros habitantes de la sabana, el quiebre sufrido con la fundación de la ciudad y el inicio de un proceso donde el agua se asume como recurso, prevaleciendo el interés por explotarla. De este modo, Bogotá no ha desarrollado sus atributos estéticos y espirituales, y ha ido tras imágenes y modelos extraños a su territorio.

    Full Text Available Este debate discute questões relacionadas ao financiamento do Sistema Único de Saúde (SUS. Na primeira parte, Ruben de Mattos defende a criação de dispositivos para a elevação progressiva dos gastos públicos em saúde. Segundo o debatedor, o maior desafio do governo será viabilizar - e sustentar - um sistema que garanta, de fato, o acesso universal e igualitário. Mattos também destaca a importância dos repasses federais entre os níveis de governos, por vê-los como instrumentos capazes de reduzir as desigualdades entre as regiões e incentivar políticas que contribuam para a consolidação do SUS. Na segunda parte, Nilson do Rosário afirma que o ajuste fiscal da década de 1990, conseqüência da política de estabilização monetária, limitou a capacidade de financiamento governamental na atenção à saúde, gerando efeitos perversos devido à ampliação da desigualdade social. A seguir, explica como o setor saúde respondeu às exigências de ajuste macroeconômico nas despesas públicas através de estratégias substitutivas, contexto em que o Programa de Saúde da Família (PSF se expandiu rapidamente, tornando-se estratégico na agenda da ampliação da atenção ambulatorial básica do país.This work discusses some of the issues related to the funding of the Brazilian National Health Service (SUS. In the first part of the paper, Ruben de Mattos advocates the creation of devices to guarantee a progressive increase in the public health budget. In the debater's view, the greatest challenge facing the government is the development - and the maintenance - of a system that can de facto guarantee universal and equalitarian access. Mattos also emphasizes the importance of the federal government's transfers of funds to local governments since the latter are seen as instrumental in the attempts to reduce inequality between regions and to encourage policies that will contribute to the SUS' consolidation.

    Full Text Available O objetivo principal deste artigo é construir um referencial teórico preliminar que possibilite a compreensão das razões que podem determinar o desempenho satisfatório das instituições de saúde no Brasil, particularmente o do Sistema Único de Saúde (SUS. A hipótese teórica, a partir dos estudos de Putnam (2005, é de que o acúmulo de Capital Social (CS em determinada sociedade está positivamente relacionado à capacidade de os governos atenderem e realizarem as demandas da população. Em outras palavras, os níveis de solidariedade e de confiança interpessoais e a existência de organizações sociais são elementos colaborativos para o desempenho das instituições políticas. O CS, na área da saúde, funcionaria como elemento de impacto positivo, não somente pelo fato de proporcionar uma vida mais saudável para as populações, reduzindo a exclusão social e aumentando a longevidade e a autoestima, mas também por ter um papel fundamental no estímulo da participação da comunidade tanto na formulação de políticas públicas como no seu controle social, o que possibilitaria o melhor funcionamento das instituições. Nesse sentido, utilizamos os dados de pesquisa quantitativa aplicados em usuários do SUS em duas cidades do Rio Grande do Sul (Caxias e Pelotas.The main objective of this paper is to construct a preliminary theoretical framework that enables the understanding of the reasons that may determine the satisfactory performance of health institutions in Brazil, particularly that of the National Health System (SUS.

Dentro do programa de Humanização implantado na Maternidade de Londrina pretendeu-se analisar o atendimento a parturiente quanto à humanização ao partocomparando com a realidade de dois hospitais de Guarapuava onde não existe o programa implantado e assim verificar se os direitos destas parturientes quanto à humanização estão sendo respeitados. Foi aplicado um questionário a 40 primíparas no puerpério imediato comperguntas semi-estruturadas. Ao comparar duas realidades diferentes, concluiu-se que alguns dos direitos das parturientes preconizados pela OMS não estavam sendo respeitados, especialmente onde não havia a implantação do parto humanizado, pois não era permitida a entrada de acompanhante e nem utilizadas técnicas de relaxamento para a parturiente, evidenciando assim que algumas instituições necessitam intensificar esses cuidados para melhorar a qualidade do atendimento prestado.This descriptive study was conducted in maternities assisted by the Brazilian Health System (SUS, in the cities of Guarapuava and Londrina, State of Paraná.

  20. Electronic detectors for electron microscopy.

    Faruqi, A R; McMullan, G

    2011-08-01

    Electron microscopy (EM) is an important tool for high-resolution structure determination in applications ranging from condensed matter to biology. Electronic detectors are now used in most applications in EM as they offer convenience and immediate feedback that is not possible with film or image plates. The earliest forms of electronic detector used routinely in transmission electron microscopy (TEM) were charge coupled devices (CCDs) and for many applications these remain perfectly adequate. There are however applications, such as the study of radiation-sensitive biological samples, where film is still used and improved detectors would be of great value. The emphasis in this review is therefore on detectors for use in such applications. Two of the most promising candidates for improved detection are: monolithic active pixel sensors (MAPS) and hybrid pixel detectors (of which Medipix2 was chosen for this study). From the studies described in this review, a back-thinned MAPS detector appears well suited to replace film in for the study of radiation-sensitive samples at 300 keV, while Medipix2 is suited to use at lower energies and especially in situations with very low count rates. The performance of a detector depends on the energy of electrons to be recorded, which in turn is dependent on the application it is being used for; results are described for a wide range of electron energies ranging from 40 to 300 keV. The basic properties of detectors are discussed in terms of their modulation transfer function (MTF) and detective quantum efficiency (DQE) as a function of spatial frequency.

    This study sought to develop methodology for the construction of a Panel for the Monitoring and Evaluation of Management of the Unified Health System (SUS). The participative process used in addition to the systematization conducted made it possible to identify an effective strategy for building management tools in partnership with researchers, academic institutions and managers of the SUS. The final systematization of the Panel selected indicators for the management of the SUS in terms of Demand, Inputs, Processes, Outputs and Outcomes in order to provide a simple, versatile and useful tool for evaluation at any level of management and more transparent and easier communication with all stakeholders in decision-making. Taking the management of the SUS as the scope of these processes and practices in all normative aspects enabled dialog between systemic theories and those which consider the centrality of the social actor in the decision-making process.

    Full Text Available Se presentan los resultados de una investigación dirigida a comprender los significados y las respuestas de madres frente al abuso sexual de sus hijas e hijos, para generar un conocimiento útil en la construcción de políticas y programas más pertinentes en la atención de este fenómeno. Es un estudio cualitativo que empleó como método los grupos de discusión con cinco madres de cuatro niñas y un niño, menores de 10 años, víctimas de abuso sexual, quienes asistían a consulta psicológica en dos centros de atención a la familia de la ciudad de Medellín, en el año 2005. Las voces de estas mujeres muestran que el abuso sexual sucede en familias vulnerables desde el punto de vista afectivo, comunicativo y socioeconómico, en las cuales este problema hace parte de su cotidianidad. El abuso sexual constituye una catástrofe que afecta el precario equilibrio socioeconómico y afectivo que estas familias logran construir para hacer frente a sus condiciones de vida angustiantes. En medio de la estigmatización que la sociedad hace de la situación, del silencio, con el cual soportan el trauma, y de un apoyo poco comprensivo y pertinente por parte de las instituciones encargadas de la atención de estas familias, las madres acometen diferentes acciones para hacer frente a su realidad. La reconfiguración de su rol como madres se convierte en un punto de partida clave para la superación del estado de impotencia en el cual quedan sumidas, posterior al abuso sexual de sus hijas(os.

    Full Text Available O presente artigo desenvolve o tema da necessidade de se regionalizar a descentralização no sentido de aglutinar o que esta supostamente poderia ter fracionado. Ao revisitar a diretriz constitucional da descentralização os autores propõem medidas que visem sua garantia ao lado de ferramentas administrativas que permitam a formação de regiões de saúde resolutivas em pelo menos 95% das necessidades de saúde do território regional, para garantir autonomia sanitária. Os autores propõem soluções que passam pela criação de pessoas jurídicas associativas regionais, resultantes da aglutinação dos entes federativos em região de saúde. Apontam ainda o que não deu certo no Sistema Único de Saúde - SUS Brasil em razão tanto de equívocos originados nas melhores intenções, quanto do oportunismo que esses equívocos geraram. Advogam os autores a necessidade de respostas jurídico-administrativas para um SUS de caráter interfederativo tanto na sua gestão, que exige compartilhamentos, quanto no seu financiamento, que se mantém interdependente também. Concluem que o único caminho para o SUS ser nacional, é regionalizá-lo e dotar a região de saúde de todo o instrumental necessário à gestão compartilhada, interfederativa e responsável.

This work aims to contribute to the debate on the inclusion of the physiotherapist in SUS (Brazil's NHS by pointing out issues that need to be deepened in future studies. Purpose: To analyze the national literature production on the relationship between the training of therapists and their work in SUS, from 1996 to 2010. Methods: Descriptive research with literature on the bases: LILACS, SCI-ELO Bank and CAPES thesis. Results: We found 13 publications, sorted by: year, publication type, region where it was published in the categories "national curriculum guidelines," "professional respon-sibility", "integrality in health" and "conceptions of teachers in training in Physiotherapy ". There no publishing from 1996 to 2005, gradually increasing from this year. It was identified a higher number of articles compared to other types of publications; there is also an important difference between the Brazilian regions, with higher prevalence of studies in the South (53.8% and a greater number of pub-lications in the category "national curriculum guidelines". Conclusion: It was possible to raise ques-tions that involve the applicability of the National Curriculum Guidelines on the pedagogical courses; suitability of teachers to the reality of SUS; investigation of the models covered in health care envi-ronments trainers, and the lack of contribution by higher education institutions on teaching-research and teaching and public service, contributing to form an important agenda of study. {#}

    This paper studied about the cooling characteristic of SUS316 surface as a PCCS heat exchanger. Specifically, filmwise and dropwise condensations on SUS316 surface were compared. The passive safety features against station blackout (SBO) and containment safety became important issue after Fukushima accident. As a result, passive containment cooling system (PCCS) is selected as candidate option for the advanced light water reactors to guarantee integrity of containment. To design efficient heat exchanger of PCCS inside of concrete containment, a number of attempts were studied to compensate the low heat transfer coefficient of condensation in non-condensable gas circumstance. The study in this paper focused on the dropwise condensation to enhance the cooling performance of PCCS heat exchanger. Bare SUS316 surface represented stable dropwise condensation phase over 12 hours of experiment for all experiment condition shown in Table I. Figure 3 shows the previous studies conducted by other researcher with our result. Subcooled temperature versus heat transfer coefficient (HTC) of DWC on various cooling surface with coatings were compared. Figure 4 and 5 shows the condensation HTC of DWC and FWC with different non-condensable gas fractions. The result of DWC with pure steam was well proportional to the power of subcooled temperature. Otherwise, the result with non-condensable gas shows HTC in low subcooled temperature under 5 .deg. C seems to be decreased, but the result was shaded by the high uncertainty. The result of FWC also proportional to power of subcooled temperature regardless of air concentration and well separated by air concentration condition.

    2014-07-01

    Full Text Available El artículo analiza la percepción que tiene una muestra representativa de la población española de entre 12 y 18 años sobre la protección de sus derechos en las cadenas de televisión. Para conseguir este objetivo, se aplicó un cuestionario de 59 preguntas diseñado para una investigación más amplia en la que se analizaba la opinión de los menores sobre la protección de sus derechos en la televisión y en Internet. Ninguna pregunta del cuestionario se refería a cadenas o programas concretos identificados por los investigadores y la información sobre estos partía de la propia opinión de los adolescentes. Los resultados que se presentan se refieren a los datos sobre televisión y, más concretamente, al respeto por los derechos fundamentales de los telespectadores en general, y de los de los menores en particular. De estos resultados se concluye que los adolescentes perciben claramente la vulneración de los derechos de igualdad, dignidad e intimidad, a la información objetiva veraz y plural y a la libre expresión y opinión –especialmente cuando ésta se refiere a los niños–. Igualmente muestran una postura crítica y de rechazo hacia los tipos de programas que no respetan sus derechos. Se propone utilizar esta capacidad crítica de los telespectadores desde una doble perspectiva: por una parte para crear escuela de ciudadanía y, por otra, para generar una sociedad más justa y equitativa.

Además se han realizado hallazgos de interés en relación con la diversidad de los tipos de contrato, la inseguridad laboral y sus efectos en los trabajadores. Son de especial interés los estudios que analizan el papel interviniente de distintas variables. En este contexto, nuestros estudios han puesto de manifiesto la relevancia de variables como la justicia organizacional, el clima de justicia organizacional, el apoyo organizacional, la empleabilidad, la dependencia laboral y el distanciamiento psicológico a la hora de predecir la variabilidad en la inseguridad laboral. Por último, las aportaciones del IDOCAL han sido especialmente relevantes al plantear el análisis de la inseguridad laboral como fenómeno colectivo y mostrar cómo la experiencia colectiva de la inseguridad tenía repercusiones sobre el bienestar de los trabajadores más allá de las producidas por sus percepciones individuales. En base a esta investigación se han propuesto en el presente artículo una serie de implicaciones para la práctica profesional.
