    Senna occidentalis (L) Link (formerly called Cassia occidentalis) is a toxic leguminous plant found ubiquitously as a contaminant of crops. All parts of the plant are toxic, but most of the S. occidentalis toxicity is found in the seeds. S. occidentalis has been shown to be toxic to several animal species, causing degenerative lesions mainly in muscles. This is the first report describing alterations in chick lymphoid organs caused by S. occidentalis seeds. The objectives of this study were to describe the effects of the treatment with seeds and its fraction external tegument (TE) on the development of chicks and their lymphoid organs bursa of Fabricius and spleen. Chicks that received a commercial ration with 1% TE had reduced body and lymphoid organ weights. The bursa of Fabricius presented reduction in the diameters of the follicles, and in the thickness of the cortical and medullary regions. The spleen presented depleted lymphoid tissue in the white pulp. These results indicate that the active principle of S. occidentalis is more concentrated on its TE fraction, and that it can cause weight loss as well as alterations in the lymphoid organs in chicks. The consequences of these alterations should be further investigated.

    Full Text Available The purpose of this 42-day study was to investigate the effects of methionine (Met deficiency on immune function by determining the relative weight, morphological and ultrastructural changes of bursae of Fabricius, cell cycle, and apoptosis of bursa cells. One hundred and twenty one-day-old avian broilers were randomly divided into two groups and fed on a control diet (starter diet, Met 0.50%; grower diet, Met 0.40% and Met-deficient diet (starter diet, Met 0.26%; grower diet, Met 0.28% for six weeks. The relative weight of bursae was decreased with Met deficiency when compared to that of the control group. Lesions were also observed in the Met-deficient group. Histopathologically, the numbers of lymphocytes in the follicles were decreased. Ultrastructurally, the mitochondria of lymphocytes were swollen in the Met-deficient group. As measured by flow cytometry, bursal cells in the G0G1 phase were significantly higher (P < 0.01, and bursal cells in the S, G2M phases and proliferating index were obviously lower (P < 0.01 with Met deficiency than in the control group. Moreover, the percentage of apoptotic cells in the bursae were significantly increased in Met-deficient birds (P < 0.01. It was concluded that Met deficiency restrained the development of the bursae of Fabricius and affected the humoral immunity of the chickens.

    The bursa of Fabricius, the central humoral immune organ unique to birds, plays an important role in B-lymphocyte differentiation. In order to gain a better understanding of the molecular mechanism of critical biological processes like B-cell immigration, differentiation, and final emigration, the transcriptional changes during embryonic and posthatch development of this organ were investigated. We generated a cDNA library from total RNA isolated from 3 representative developmental stages (embryonic day [ED] 10, posthatch d 2 and d 21). We generated over 70 million high-quality reads from the cDNA library by using deep sequencing. The uniquely mapped sequences of ED 10, d 2 and d 21 were 71087280, 59167491 and 70263675 respectively. All of the differential expressed genes were involved in Vitamin A metabolism, regulation of actin cytoskeleton, Wnt signaling pathway, MAPK signaling pathway, Jak-STAT signaling pathway, Notch signaling pathway, Toll-like receptor signaling pathway. The RNA-seq analysis provides a powerful method for analyzing the transcriptome and investigating the transcriptional changes of different development stages of bursa of Fabricius. The assembled bursa transcriptome provides an essential resource for future investigations about chicken Bursa development. PMID:26994188

    The mitotic index in the cortical compartment of the follicles of the bursa of Fabricius from chicks immunized with sheep red blood cells (SRBC) is always higher when compaired with non-immunized ones. This mitotic index reachs its maximum 6 days after the SRBC injection, coincident with the highest serum antibody titer. The mitotic activity in the cortex of the follicles of the bursa of Fabricius is always higher than that of the medulla during the postembryonic development of chickens (PROCHAZKA, RODAK, KREJCI 1967). Otherwise it is almost established that the cortex is a zone of continuous lymphocyte proliferation, not occuring the same with the medulla. In addition these bursal histological structures are considered as 2 distinct compartments (GROSSI et al. 1974). The purpose of this paper is to study the response in the mitotic index of the cortical and medullary compartments of the follicles of the bursa of immunized and non-immunized chicks. To correlate possible changes in the mitotic index with circulating antibody levels, the serum antibody titer from the same birds was also recorded.

  11. Experimental evidence for the ectodermal origin of the epithelial anlage of the chicken bursa of Fabricius.

    The bursa of Fabricius (BF) is a central lymphoid organ of birds responsible for B-cell maturation within bursal follicles of epithelial origin. Despite the fundamental importance of the BF to the birth of B lymphocytes in the immune system, the embryological origin of the epithelial component of the BF remains unknown. The BF arises in the tail bud, caudal to the cloaca and in close association with the cloacal membrane, where the anal invagination (anal sinus) of ectoderm and the caudal endodermal wall of the cloaca are juxtaposed. Serial semi-thin sections of the tail bud show that the anal sinus gradually transforms into the bursal duct and proctodeum, which joins the distal part of the cloaca during late embryogenesis. These anatomical findings raise the possibility that the ectoderm may contribute to the epithelial anlage of the BF. The expression of sonic hedgehog and its receptor in the embryonic gut, but not in the BF, further supports an ectodermal origin for the bursal rudiment. Using chick-quail chimeras, quail tail bud ectoderm was homotopically transplanted into ectoderm-ablated chick, resulting in quail-derived bursal follicle formation. Chimeric bursal anlagen were generated in vitro by recombining chick bursal mesenchyme with quail ectoderm or endoderm and grafting the recombination into the chick coelomic cavity. After hematopoietic cell colonization, bursal follicles formed only in grafts containing BF mesenchyme and tail bud ectoderm. These results strongly support the central role of the ectoderm in the development of the bursal epithelium and hence in the maturation of B lymphocytes.

    Concurrent fowlpox and candidiasis diseases occurred in a backyard chicken flock. Four deceased chickens (one Nagoya breed and three white silkie chickens) were examined for diagnosis. At necropsy, white curd-like plaques were observed in the crop. Fungal elements that stained positive for Candida albicans with immunohistochemistry were distributed throughout the tongue, choanal mucosa, esophagus, and crop. Typical fowlpox lesions, composed of proliferating epithelial cells with ballooning degeneration and viral intracytoplasmic inclusions, were observed in the conjunctiva, nasal mucosa, and skin around the cloaca. Interestingly, hyperplastic interfollicular epithelium with rare virus inclusions was observed in the bursa of Fabricius (BF). Some bursal follicles were replaced by proliferating epithelial cells. These proliferating cells immunohistochemically stained positive for cytokeratin. PCR and subsequent genetic sequencing detected the C. albicans gene in the crop, and fowlpox virus genes in the BF. These results indicate that this outbreak was a rare presentation of fowlpox in spontaneously infected chickens, with unusual pox lesions in the BF. PMID:27610735

    Full Text Available Low pathogenic avian influenza (H9N2 is of major concern for the poultry industry especially in Iran, as the virus can spread rapidly in and between flocks, causing high mortality and severe economic losses. The aim of this study was to determine the pathogenicity of H9N2 avian influenza virus in thymus and bursa of Fabricius of commercial broiler chickens, so we studied the histologic lesions of this isolate in these organs following intranasal (IN inoculation. Twenty-four 3-week-old chickens were inoculated with 106 EID50 per bird with H9N2 avian influenza virus. Then on days 1, 2, 4, 6, 8 and 10 post-inoculation (PI, samples of the thymus and bursa of Fabricius were collected for histopathological studies. In inoculated chickens, lymphocyte depletion in the thymus, follicular atrophy and cystic follicles in the bursa of Fabricius were seen. The results indicated that the H9N2 has some immunosuppressive effects on chicken lymphoid organs.

    Full Text Available Abstract Background Two-dimensional gel electrophoresis (2-DE is a powerful method to study protein expression and function in living organisms and diseases. This technique, however, has not been applied to avian bursa of Fabricius (BF, a central immune organ. Here, optimized 2-DE sample preparation methodologies were constructed for the chicken BF tissue. Using the optimized protocol, we performed further 2-DE analysis on a soluble protein extract from the BF of chickens infected with virulent avibirnavirus. To demonstrate the quality of the extracted proteins, several differentially expressed protein spots selected were cut from 2-DE gels and identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS. Results An extraction buffer containing 7 M urea, 2 M thiourea, 2% (w/v 3-[(3-cholamidopropyl-dimethylammonio]-1-propanesulfonate (CHAPS, 50 mM dithiothreitol (DTT, 0.2% Bio-Lyte 3/10, 1 mM phenylmethylsulfonyl fluoride (PMSF, 20 U/ml Deoxyribonuclease I (DNase I, and 0.25 mg/ml Ribonuclease A (RNase A, combined with sonication and vortex, yielded the best 2-DE data. Relative to non-frozen immobilized pH gradient (IPG strips, frozen IPG strips did not result in significant changes in the 2-DE patterns after isoelectric focusing (IEF. When the optimized protocol was used to analyze the spleen and thymus, as well as avibirnavirus-infected bursa, high quality 2-DE protein expression profiles were obtained. 2-DE maps of BF of chickens infected with virulent avibirnavirus were visibly different and many differentially expressed proteins were found. Conclusion These results showed that method C, in concert extraction buffer IV, was the most favorable for preparing samples for IEF and subsequent protein separation and yielded the best quality 2-DE patterns. The optimized protocol is a useful sample preparation method for comparative proteomics analysis of chicken BF tissues.

    Hongyan Sun

    Full Text Available Extraintestinal pathogenic Escherichia coli (ExPEC has major negative impacts on human and animal health. Recent research suggests food-borne links between human and animal ExPEC diseases with particular concern for poultry contaminated with avian pathogenic E. coli (APEC, the avian ExPEC. APEC is also a very important animal pathogen, causing colibacillosis, one of the world's most widespread bacterial diseases of poultry. Previous studies showed marked atrophy and lymphocytes depletion in the bursa during APEC infection. Thus, a more comprehensive understanding of the avian bursa response to APEC infection will facilitate genetic selection for disease resistance. Four-week-old commercial male broiler chickens were infected with APEC O1 or given saline as a control. Bursas were collected at 1 and 5 days post-infection (dpi. Based on lesion scores of liver, pericardium and air sacs, infected birds were classified as having mild or severe pathology, representing resistant and susceptible phenotypes, respectively. Twenty-two individual bursa RNA libraries were sequenced, each yielding an average of 27 million single-end, 100-bp reads. There were 2469 novel genes in the total of 16,603 detected. Large numbers of significantly differentially expressed (DE genes were detected when comparing susceptible and resistant birds at 5 dpi, susceptible and non-infected birds at 5 dpi, and susceptible birds at 5 dpi and 1 dpi. The DE genes were associated with signal transduction, the immune response, cell growth and cell death pathways. These data provide considerable insight into potential mechanisms of resistance to ExPEC infection, thus paving the way to develop strategies for ExPEC prevention and treatment, as well as enhancing innate resistance by genetic selection in animals.

    Full Text Available Fifty Bursa of Fabricius (BF were examined by conventional optical microscopy and digital images were acquired and processed using Matlab® 6.5 software. The Artificial Neuronal Network (ANN was generated using Neuroshell® Classifier software and the optical and digital data were compared. The ANN was able to make a comparable classification of digital and optical scores. The use of ANN was able to classify correctly the majority of the follicles, reaching sensibility and specificity of 89% and 96%, respectively. When the follicles were scored and grouped in a binary fashion the sensibility increased to 90% and obtained the maximum value for the specificity of 92%. These results demonstrate that the use of digital image analysis and ANN is a useful tool for the pathological classification of the BF lymphoid depletion. In addition it provides objective results that allow measuring the dimension of the error in the diagnosis and classification therefore making comparison between databases feasible.Cinquenta Bursa de Fabrícius (BF foram examinadas através de microscopia óptica convencional e imagens digitais foram obtidas e processadas através do software Matlab® 6.5.

    2012-06-01

    Full Text Available The outbreaks of IBD (infectious bursal disease are frequently observed among correctly vaccinated broiler flocks in Algerian Nord-East region. The present study aimed to search for the immunosuppression state as possible consequence of IBD. Our investigation focused on nine broilers flocks whom one suffering from IBD. Total of 400 bursa cloacae (bursa Fabricius were collected from broiler chickens during the rearing period or at slaughtering. The parameters of the bursa cloacae are evaluated: body weight ratio, index bursal, morphometric characteristics and the histopathological observations. The results obtained show that the weight and diameter of bursa Fabricius are not proportional to the age and weight of chickens. The weight and size of the bursa Fabricius were found lower than the accepted standards. According to the evaluation system in effect, 58 % of examined chickens belong to the poor category and 29 % to the excellent category. Such results indicate bursa atrophy and confirm state of immunosuppression which was suspected because of poor performances recorded in some broiler flocks. In conclusion, the bursa characteristics (body weight ratio, morphometric and histopathological studies are practical and not expensive tools for any field investigation to evaluate the immune status of broilers

    The authors present a review of the anatomy of the major bursae around the shoulder joint and discuss the use of the different imaging modalities which demonstrate their radiologic features. The calcified subacromial-subdeltoid bursa has a characteristic appearance on plain radiographs. When inflamed it can be visualized by ultrasound and magnetic resonance imaging. Calcific bursitis may involve the subcoracoid bursa. This bursa may mimic adhesive capsulitis of the shoulder or complete rotator cuff tear when injected inadvertently during shoulder arthrography. Less well known are three coracoclavicular ligament bursae. These are also subject to calcific bursitis and have a typical radiologic appearance. (orig.). With 6 figs.

Os animais foram distribuídos em cinco grupos: 1-controle; e 2 a 5- com 24, 48, 72 e 96 horas pós-inoculação, respectivamente. Fragmentos da bursa de Fabricius foram colhidos para processamento histológico e extração de RNA. Lâminas coradas em HE e TUNEL (marcação in situ da fragmentação do genoma com transferase terminal de deoxinucleotídeo foram utilizadas na morfometria do índice apoptótico. Amostras de mRNA foram testadas para a expressão dos genes VP2 e GAPDH utilizando-se transcrição reversa e RT-PCR. Utilizou-se um kit SYBR GREEN PCR, e a reação foi desenvolvida em ABI Prism 7000 SDS. Os índices apoptóticos cresceram progressivamente indicando uma relação na atrofia bursal causada pelo VDIB. Paralelamente, os resultados da PCR em tempo real demonstraram queda da carga viral nas células linfóides da bursa nos diferentes intervalos de tempo do experimento. Esses resultados sugerem um papel protetor da apoptose na diminuição da replicação viral.Twenty-nine SPF 1-day-old chicks were inoculated with infectious bursal disease virus (IBDV to evaluate early apoptosis and the expression of viral protein 2 (VP2 and glyceraldehyde-3-phosphate dehydrogenease (GAPDH.

    The bicipitoradial bursa lies at the insertion of the biceps tendon on the radial tuberosity. It is an unusual site for chronic bursitis. It can be treated conservatively with aspiration and steroid injection. Surgical excision of the bursa is indicated in case of infection cause, failed conservative treatment with recurrence of the enlarged bursa and pain after aspiration, the presence of nerve compression with neurological impairment, mechanical limitation to flexion and extension of the elbow or biceps tendon degeneration, and/or functional impairment. Open resection through the anterior approach requires extensive dissection to expose the radial tuberosity and the radial neck, which increases the risk of neurovascular injury. Endoscopic resection is possible through distal biceps tendoscopy and endoscopy around the radial neck. It is technically demanding and should be reserved to the experienced elbow arthroscopist.

    A 37-year-old military mechanic presented to our institution with a chronic history of a slowly enlarging left elbow antecubital fossa mass. There was no history of other chronic illness or trauma. Magnetic resonance imaging (MRI) and excisional biopsy revealed fatty villi and synovial inflammation within the left bicipitoradial bursa, consistent with lipoma arborescens. Four years later the patient presented with a 6-month history of swelling at the antecubital fossa of the opposite elbow. Diagnostic computed tomography and MRI examinations were performed. The surgical and pathologic findings confirmed the imaging diagnosis of lipoma arborescens at the right bicipitoradial bursa. (orig.)

    The author reports six cases in whom there was contrast filling of a bursa related to the tendon of the flexor hallucis longus during the course of an arthrogram. All patients had had joint symptoms for a prolonged period; in three patients there was osteochondritis dissecans. Possible mechanism for the development of the bursa is discussed. The hypothesis is proposed that the bursa results from increased pressure in the joint due to recurrent synovitis.

    Malaria is still one of the important public health problems in Anatolia. Since Bursa is a well-developed industrial and agricultural province in the Marmara region, migration rate to this region from eastern and southeastern regions of Turkey is quite high. In this retrospective study, malaria cases detected by the Malaria Control Unit Division of the Bursa Health Directorship from 1986-2002 have been evaluated. The total number of slide-positive cases was 700. Out of the 700 cases of malaria, 695 (99.3%) were found to have been caused by Plasmodium vivax and 5 (0.7%), by P. falciparum. Of these cases, 68.8% were male and of the males, 18.4% were soldiers. The majority of the cases (70.5%) had come from the southeastern region of Anatolia. Positivity rates were found to be highest in 1995 (21%) and 1996 (18.5%). In this study, we have reviewed the malaria cases according to age, gender and occupation as well as transmission characteristics, locality and source of infection. PMID:17160827

    Programmed suicide or apoptosis, due to activation of endogenous nucleases, occurs in immature CD4{sup {minus}}85{sup {minus}} mammalian thymus cells. Like the thymus, the bursa of Fabricius is a site of massive lymphopoiesis accompanied by cell death in vivo. In the present study the authors have, therefore, examined whether chicken bursa and thymus cells exhibit apoptosis. Bursa and thymus cells from SC chickens, 4-10 weeks of age, were incubated for 8-24 hrs with various reagents. Genomic DNA was isolated, electrophoresed in 3% Nusieve agarose gels, and examined for patterns of DNA fragmentation. A laddering of DNA in multiples of 200 base pairs, indicative of apoptosis, was observed with both bursa and thymus cells. These patterns of DNA fragmentation from bursa cells could be prevented by adding phorbol myristic acetate during culture and, more effectively, by PMA plus ionomycin, but not by ionomycin alone or by anti-{mu}. PMA did not affect the patterns of DNA fragmentation seen with spleen cells. Addition of the protein kinase C inhibitor staurosporin inhibited the preventive effect of PMA on apoptosis. PMA also greatly promoted the survival of bursa cells in culture, as assayed by percentage cell death and by {sup 3}H-thymidine incorporation. It is concluded that bursa and thymus cells from the chicken exhibit apoptosis. The data further suggest that protein kinase C activation protects apoptosis in cultured bursa cells.

    The iliopsoas bursa is the largest bursa in the region of hip joint. It is unusual that these bursa become symptomatic. However the bursa can compress femoral vein, leading to lower extremity edema. A 58-year-old man was referred to our department for his unilateral leg edema which had been treated as deep vein thrombosis without any favorable response. Magnetic resonance angiography was performed, which demonstrated enlarged iliopsoas bursa compressing his femoral vein. Surgical removal of the bursa was performed. The postoperative course was uneventful, and the patient is free from symptoms with no evidence of recurrence.

    In estimating the postmortem interval (PMI) using maggots obtained during autopsy, the forensic entomologist makes decisions regarding the effects of low-temperature storage of the body on the insects. In this case report, a corpse was found in an abandoned house in the residential area of Bukit Mertajam, Penang, Malaysia. The maggots were found to be alive inside the mouth of the deceased although the corpse had been in the morgue cooler for 12 days. The maggots were reared and identified as Chrysomya megacephala (Fabricius). The emerged adult flies were kept as a stock colony, and the duration of development under the indoor fluctuating temperature regime was studied. The total duration of developmental process of this species was 9.5 ± 0.5 days, and the PMI estimated was 3.2 ± 0.6 days. This case report demonstrates the survival of Ch. megacephala maggots for 12 days and their growth inside the morgue cooler.

    Septic peritonitis occurs relatively commonly in dogs. Secondary septic peritonitis is usually associated with perforation of intestines or infected viscera, such as the uterus in pyometra cases. The aim of this study was to evaluate the bacterial flora in the ovarian bursae of intact bitches as a potential source of contamination. One hundred forty dogs, clinically suspected of pyometra, were prospectively enrolled. The control group consisted of 26 dogs that underwent elective ovariohysterectomies and 18 dogs with mammary gland tumors that were neutered at the time of mastectomy. Bacteriology samples were taken aseptically at the time of surgery from the bursae and the uterus in all dogs. Twenty-two dogs that were clinically suspected of pyometra had sterile uterine content ("mucometra" cases); the remaining 118 had positive uterine cultures ("pyometra" cases) and septic peritoneal fluid was present in 10% of these cases. Of the 118 pyometra cases, 9 had unilateral and 15 had bilateral bacterial colonization of their ovarian bursae. However, the bacteria from the ovarian bursa were similar to those recovered from the uterine pus in only half of the cases. Furthermore, positive bursae were also seen in one mucometra dog (unilateral) and in four control dogs (two unilateral and two bilateral). The data illustrate that the canine ovarian bursa can harbor bacteria. The biological importance of these isolations remains unclear. PMID:25127745

    Greater trochanteric pain syndrome (GTPS) is a pathology that can involve the trochanteric bursa or the tendons which attach to the greater trochanter. To clarify the potential importance of bursa versus tendon pathology and of substance P (SP) in contributing to pain in this condition tendon and bursa tissue biopsies were obtained from 34 patients with GTPS and 29 control subjects. Specimens were evaluated via light microscopy for histopathological and morphological differences, as well as using immunohistochemistry for macrophages (CD68), inflammatory cells (CD45) and SP. Bursa [stroma score, mean (SD): 4.18 (1.65) vs. 2.53 (1.61), p = 0.051] and tendon [Bonar score, mean (SD): GTPS mean (SD) 12.65 (2.0), control (10.43 (4.84), p = 0.04] from subjects with GTPS demonstrated more extensive signs of pathology than specimens from control subjects. There was a significantly greater presence of SP in the bursa (frequency: 9/12 vs. 6/16, p = 0.047), but not in the tendon (8/12 vs. 8/15, p = 0.484) of subjects with GTPS compared to controls. An increased presence of SP in the trochanteric bursa may be related to the pain associated with GTPS. PMID:24563019

    Objective. As a therapeutic injection into the subacromial bursa (SAB) is commonly performed for impingement syndrome, it is important to know whether this fluid can be retained for a period of time and cause confusion with a pathologic collection of fluid. This study identifies and describes the appearance of recent subacromial injection using MR imaging, and the appearance of a potential complication.Design and patients. Fourteen asymptomatic shoulders were studied with MR imaging using fast spin echo T2-weighted imaging (1.5 T) prior to injection with 7 cm{sup 3} of xylocaine. Four shoulders had subacromial fluid and were eliminated from the study. The remaining 10 (9 men, 1 woman; age range 27-36 years, average age 33 years) were then re-imaged immediately, and at 6, 12 and 24 h after the injection or until fluid resolved. Each set of images was reviewed for the presence of fluid in the SAB and for additional abnormalities.Results. Fluid was identified in all subjects in the SAB in the immediate, 6 and 12 h post-injection images. At 24 h, fluid was not identified within the SAB in eight of 10 patients. In one patient fluid resolved in 48 h. The other continued to demonstrate fluid in the SAB and in the joint as well as abnormal signal in the infraspinatus muscle from a presumed myositis. Imaging was performed up to 10 days after the injection in this patient.Conclusions. It is known that fluid identified in the SAB without evidence of a cuff tear may be due to bursitis. However, if MR imaging is performed within 24 h of injection, the presence of the fluid may be iatrogenic. In addition, the history of recent therapeutic injection is very important as complications such as myositis can occur as a result of the injection. Knowledge of injection prior to imaging is vital for accurate interpretation of MR shoulder examinations. (orig.)

    Objective: To assess dynamic MRI with Gd-DTPA enhancement for evaluating inflammatory changes in the subacromial bursa. Design and patients: We detected the signal intensity changes in dynamic MRI of the subacromial bursa, and confirmed these macroscopically by arthroscopy and histologically. The signal intensity was measured using built-in software, and the enhancement ratio (E ratio) was calculated from dynamic MR images. In addition, as a parameter of the rate of the increase in the signal intensity from 0 to 80 s, the mean increase per second in the E ratio was obtained as the coefficient of enhancement (CE). The correlation was studied of the E ratio and CE with the arthroscopic findings (redness, villous formation, thickening and adhesion), and of the E ratio and CE with the histological findings (capillary proliferation, papillary hyperplasia, fibrosis and inflammatory cell infiltration) of the subacromial bursa. Of patients with shoulder pain, this study included those with rotator cuff injury; patients with rheumatoid arthritis or pitching shoulder disorders were excluded. There were 27 patients (15 men, 12 women) ranging in age from 25 to 73 years (mean 49.1 years). Dynamic MRI of the shoulder was also performed on the healthy side of 10 patients and in five normal young volunteers. Results and conclusions: Changes in signal intensity on dynamic MRI were measured in the subacromial bursa. The E ratio (80 s) and CE (0-80 s) were significantly correlated with redness and villous formation as arthroscopic findings, positively correlated with capillary proliferation and papillary hyperplasia as histological findings (p < 0.05), and negatively correlated with fibrosis as a histological finding (p < 0.05) in the subacromial bursa. The patterns of dynamic curves were well correlated with the bursoscopic and histological findings of the synovium of the subacromial bursa.

    Polyploidization is a dominant feature of flowering plant evolution. However, detailed genomic analyses of the interpopulation diversification of polyploids following genome duplication are still in their infancy, mainly because of methodological limits, both in terms of sequencing and computational analyses. The shepherd's purse (Capsella bursa-pastoris) is one of the most common weed species in the world. It is highly self-fertilizing, and recent genomic data indicate that it is an allopolyploid, resulting from hybridization between the ancestors of the diploid species Capsella grandiflora and Capsella orientalis. Here, we investigated the genomic diversity of C. bursa-pastoris, its population structure and demographic history, following allopolyploidization in Eurasia. To that end, we genotyped 261 C. bursa-pastoris accessions spread across Europe, the Middle East and Asia, using genotyping-by-sequencing, leading to a total of 4274 SNPs after quality control. Bayesian clustering analyses revealed three distinct genetic clusters in Eurasia: one cluster grouping samples from Western Europe and Southeastern Siberia, the second one centred on Eastern Asia and the third one in the Middle East. Approximate Bayesian computation (ABC) supported the hypothesis that C. bursa-pastoris underwent a typical colonization history involving low gene flow among colonizing populations, likely starting from the Middle East towards Europe and followed by successive human-mediated expansions into Eastern Asia. Altogether, these findings bring new insights into the recent multistage colonization history of the allotetraploid C. bursa-pastoris and highlight ABC and genotyping-by-sequencing data as promising but still challenging tools to infer demographic histories of selfing allopolyploids.

    Ticks are obligatory blood-sucking arthropod (Acari:Ixodida) ectoparasites of domestic and wild animals as well as humans. The incidence of tick-borne diseases is rising worldwide, challenging our approach toward diagnosis, treatment and control options. Rhipicephalus bursa Canestrini and Fanzago, 1877, a two-host tick widely distributed in the Palearctic Mediterranean region, is considered a multi-host tick that can be commonly found on sheep, goats and cattle, and occasionally on horses, dogs, deer and humans. R. bursa is a species involved in the transmission of several tick-borne pathogens with a known impact on animal health and production. The aim of this study was to estimate R. bursa prevalence in Portugal Mainland and circulating pathogens in order to contribute to a better knowledge of the impact of this tick species. Anaplasma marginale and Theileria spp. were detected and classified using phylogenetic analysis. This is the first report of Theileria annulata and Theileria equi detection in R. bursa ticks feeding on cattle and horses, respectively, in Portugal. This study contributes toward the identification of currently circulating pathogens in this tick species as a prerequisite for developing future effective anti-tick control measures. PMID:26797395

    Several viruses of the family of Adenoviridae are associated with disease in birds. Here we report the detection of a novel adenovirus in the cloacal bursa of herring gulls (Larus argentatus) and lesser black-backed gulls (Larus fuscus) that were found dead in the Netherlands in 2001. Histopathological analysis of the cloacal bursa revealed cytomegaly and karyomegaly with basophilic intranuclear inclusions typical for adenovirus infection. The presence of an adenovirus was confirmed by electron microscopy. By random PCR in combination with deep sequencing, sequences were detected that had the best hit with known adenoviruses. Phylogenetic analysis of complete coding sequences of the hexon, penton and polymerase genes indicates that this novel virus, tentatively named Gull adenovirus, belongs to the genus Aviadenovirus. The present study demonstrates that birds of the Laridae family are infected by family-specific adenoviruses that differ from known adenoviruses in other bird species.

    Objective: To investigate the morphological changes of the roof of the subacromial bursa (SAB) and its involvement extent after rotator cuff tear. Methods: In the experimental group, the roof of SAB was obtained from 30 cases of rotator cuff tear both at the tear site and a site 2.5-3.0 cm distal to the tear site during rotator cuff repair. In the control group, the roof of SAB was obtained from the exposed site of recurrently dislocated shoulder or fractured humeral shaft of 8 cases.The specimens were stained with hematoxylin and eosin and observed under a transmission electron microscope. The cell number was quantitated through counting the bluestained nucleus in SAB with a computer image analysis system.Results: The number of cells increased significantly in the roof of SAB in the experimental group compared with that of the control group. However, no difference of the bursal reaction was found among the type of rotator cuff tear, the bursa thickness and the presence of fluid in the bursa. The great majority of cells were type B cells observed under the transmission electron microscope.Conclusions: The increase in cell number in the roof of SAB in the experimental group is a reactive increase rather than an inflammatory process and the involvement of SAB is not limited in extent. The change of the roof of SAB is a secondary reaction to the rotator cuff tear.

The scope is further narrowed to the Shariah-compliant companies in ACE Market of Bursa Malaysia. A total of 102 company annual reports for the year 2012 are examined to analyze the companies’ reporting practice using content analysis. Regression analysis was used to examine the relationship between corporate social responsibility disclosure (CSRD and independent variables consisting of independent non-executive directors, Muslim chairman/president of the board, CEO duality, frequency of board meetings and auditor types. Study findings suggest that there is fair amount of CSR disclosure amongst Shariah-compliant companies listed with Bursa Malaysia. The results of the study demonstrate only the type of auditors employed have a significant relationship with CSR disclosure. In contrast, the extent of CSR disclosure is insignificant with regard to the proportion of independent non-executive directors, Muslim chairman/president of the board, CEO duality and frequency of board meetings. The research shows that the level of CSR disclosures among Shariah-compliant companies in ACE Market is moderate but the varieties of disclosure are impressive. This study provides evidence for regulatory bodies such as Shariah Advisory Council (SAC of the Securities Commission Malaysia and Bursa Malaysia to look further at Shariah-compliance guidelines and to enforce new policies on corporate social disclosure

    Results obtained in studies can contribute to the advancement of science and innovative methods and techniques for developing practical activities. Reporting conditions that may restrict the implementation of research is critical to ensure the optimal development of further technical studies. The objective of this study was to assess the walking stability of R. dominica on a flat and smooth surface. The study was based on the determination of mortality, morphology and walking stability of the insect outside the grain mass, on a flat and smooth surface. Mortality of adults of this Coleoptera in conditions with and without food was similar, which explains the difficulty that this insect had for accessing the food source on the flat and smooth surface. The measurements of body length (BOL), width (BOW) and height (BOH) of R. dominica were compared with those of Tribolium castaneum (Coleoptera: Tenebrionidae), which showed good ability to walk in these conditions. This study indicated that the former presents lower BOL and BOW, and greater BOH than the second, and all these variables showed differences when analyzed simultaneously by means of the construction of multivariate morphometric indices (Width × Height, Length × Height and Height × Length × Width). These morphometric variables, together with the definition of the geometry most similar to the body shape, resulted in determination of the center of gravity (CG) and static rollover threshold (SRTgeom) for both species. Rhyzopertha dominica and T. castaneum presented CGs considered high and low, respectively, and together with the values obtained for SRTgeom, may justify that R. dominica can be considered a less stable species during movement, and presents greater risk of rollover on flat and smooth surfaces.

    Full Text Available Lantana camara L. is a widespread plant species mostly native to subtropical and tropical regions of the world. In this study, insecticidal and repellent activities of L. camara essential oil were evaluated against Callosobruchus maculatus (Fabricius (Col: Bruchidae. Analysis of chemical composition by gas chromatography/mass spectrometry (GC/MS showed high amounts of sesquiterpenes, mainly α-humelene (23.3% and cis-caryophyllene (16.2%. The results showed that the essential oil of L. camara has strong repellent activity against adults of C. maculatus at all tested concentrations. After 2 and 4 h, 97.4 and 100% repellency was seen at highest concentrations of 0.4 μL cm-2, respectively. Moreover, the oil was found to be toxic to adults when applied by fumigation. Responses varied with the gender of insect and exposure time. The LC50 values were 282.7 and 187.9 μL L-1 for females and males, respectively. An increase in the exposure time from 3 to 24 h caused increasing in mortality from 23.6 to 100% in males and from 14.1 to 97.1% in females, at highest concentration (1160 μL L-1.

    International Nuclear Information System (INIS)

    The possibility of the radiolabelling method for Chrysomya megacephala (Fabricius, 1794) (Diptera, Calliphoridae) was studied. Five males from 0 to 16 hours of age proceeding from artificial rearing, were labelled through its diet. The radioisotope used was Phosphorus-32, in the chemical form of sodium phosphate (Na2 H32 P O4), mixed into a sucrose solution of 10% sugar. After 25 hours of labelling and feeding period, each male was placed into a cage together with 20 females of the same age, for mating. The radioactivity of each male and of the genitalia of each female was verified through liquid scintillation counting. It was observed that the males showed high activity levels, above 1,7 x 106 counts per minute at an average of 3,1 x 106 cpm. Much smaller and more variable was the activity showed by the genitalia of the females: between 123 and 35.323 cpm, at an average of 2.986 cpm. As a conclusion it could be observed that the methodology of tagging this species of flies with radioactive phosphorus is perfectly suitable for ecological and behavioural studies. During the experiments of radiolabelling it could be observed that the predator Belonuchus rufipennis (Fabr., 1801) (Col., Staphylinidae) caused severe attack to recently laid eggs of the flies. To verify the possibility of rearing this insect in the laboratory, adults of the predator were maintained into Petri dishes containing eggs and water. Eggs of the predator, newly hatched larvae, pupae and adults were transferred separately into other Petri dishes for daily observations. As results it could be observed that the egg phase of the predator was two days. The development of the larvae is 10,7 days, and 5,9 days of the pupae. As a remark it could be observed that the eggs of the flies were well accepted by the predator even if dead, after maintenance into a freezer. As a final conclusion it could be confirmed that rearing of Belonuchus rufipennis is perfectly feasible under laboratory conditions using as

    Traditional portfolio optimization methods in the likes of Markowitz' mean-variance model and semi-variance model utilize static expected return and volatility risk from historical data to generate an optimal portfolio. The optimal portfolio may not truly be optimal in reality due to the fact that maximum and minimum values from the data may largely influence the expected return and volatility risk values. This paper considers distributions of assets' return and volatility risk to determine a more realistic optimized portfolio. For illustration purposes, the sectorial indices data in FTSE Bursa Malaysia is employed. The results show that stochastic optimization provides more stable information ratio.

    Full Text Available The effects of environmental parameters on biomass, growth and pigment content of the red seaweed Gracilaria bursa-pastoris (S.G. Gmel. P.C. Silva was investigated under field conditions in Thau Lagoon (France. The seaweed was cultivated in cages placed at three depths (1.0, 2.0 and 4.0 m over a one-year period. The results showed elevated biomass and growth values in the spring and autumn, when temperature, light and photoperiod values were similar. The highest specific growth rates (SGR were obtained at 1.0 m (4.95±0.29% day-1 and 2.0 m (4.45±0.33% day-1. At a depth of 4.0 m, the seaweed never exceeded 2% day-1 and obtained null values in the summer. The concentrations of phycoerythrin (RPE and chlorophyll (CHL a showed maximum values in the winter and minimum values in the summer. This evolution was related to water temperature, light intensity and nitrogen content in the algal tissue. The results obtained in this study show that the water depth influenced the growth and pigment composition of G. bursa-pastoris.

    Nickel accumulated in midugt of Spodoptera litura Fabricius could induce the expression of metal-Iothionein, one of the most important detoxification proteins in organisms. In the present study, the effects of dietary nickel on the activities of detoxification enzymes, such as carboxylesterase (CarE) and glutathione S-transferase (GST) in the midgut of S. litura larvae have been studied to get an un-derstanding of the detoxification mechanisms of S. litura larvae to excessive nickel. Results showed that CarE activities in the midgut of the 5th instar larvae decreased at lower levels of nickel (≤5 mg/kg), while increased with increasing nickel doses at higher levels of nickel (≥10 mg/kg) exposure in suc-cessive 3 generations. CarE activities of the 6th instar larvae were also characterized as inhibited at low levels of nickel exposure, and improved at higher levels in the 1st generation. CarE activities of 6th instar larvae in the 2rid and 3rd generations were all lower than that in control. However, GST activities in the midgut of the 5th and 6th instar larvae all increased with increasing nickel doses (1-20 mg/kg) in diets.

    Full Text Available The presence of nanoparticles on the body of the honeybee Apis dorsata Fabricius, was investigated for the first time to better understand the bee’s behaviour. These have been observed by using Scanning Electron Microscopy (SEM, Transmission Electron Microscopy (TEM and confirmed by Atomic Force Microscopy (AFM. Our study clearly denotes that the Indian rock honey bee Apis dorsata possess calcium silicate and calcium phosphate nanoparticles on its body surface of 5-50 nm in diameter. In particular, the nanoparticles on the abdomen and thorax of A. dorsata have an average diameter of about 10 nanometers and they are smaller than those found on wings of the same bees which are about 20 nanometers. The nanoparticles found are different of the ones previously observed on honey bees or other insects. The origin and role of these natural nanoparticles on the body of the Indian rock bee need to be to be further investigated; more research in the subject might raise important aspects in relation to the conservation of these unique pollinators.

    Full Text Available Energetic cost of digging behavior in workers of the leaf-cutting ant Atta sexdens (Fabricius. During nest excavation, leaf-cutting ant workers undergo reduction in their body reserve, particularly carbohydrates. In order to estimate the energetic cost of digging, groups of 30 workers of the leaf-cutting ant Atta sexdens were sealed in a hermetic chamber for 24, 48 and 72 hours, with and without soil for digging, and had the CO2 concentration measured using respirometric chambers as well as volume of soil excavated (g. As expected, the worker groups that carried out soil excavation expelled more carbon dioxide than the groups that did not excavate. Therefore, a worker with body mass of 9.65 ± 1.50 mg dug in average 0.85 ± 0.27 g of soil for 24 hours, consuming ca. 0.58 ± 0.23 J. In this study, we calculate that the energetic cost of excavation per worker per day in the experimental set-up was ca. 0.58 J.

    Full Text Available For the first time the pollination of a poorly known, terrestrial orchid, Habenaria pleiophylla Hoehne & Schlechter, 1921 (Orchidaceae by a passion vine butterfly, Heliconius erato phyllis (Fabricius, 1775 (Lepidoptera, Nymphalidae is reported. Number of pollinia-carrying individuals was determined on a population of H. erato phyllis in Horto Florestal Barba Negra, Barra do Ribeiro County, Rio Grande do Sul State. The pollination mechanism was described under laboratory conditions, in association with the butterfly feeding habit and the orchid flower morphology. Habenaria pleiophylla pollinia are cemented during nectar feeding on the ventral portion of the compound eyes near H. erato phyllis proboscis base. The pollinia are transferred to the stigma of other flowers during subsequent visits. Both males and females of H. eralo phyllis frequently visit H. pleiophylla flowers in the Barba Negra Forest. About forty percent of field collected adults had attached pollinia, ranging in number from one to 19 per individual. Thus, H. eralo phyllis may play an important role in the reproductive biology of this H. pleiophylla population.

In the present study, in order to comprehensively understand the physiological and biochemical functions of C. megacephala, we performed RNA-sequencing and digital gene expression (DGE profiling using Solexa/Illumina sequencing technology. METHODOLOGY/PRINCIPAL FINDINGS: A total of 39,098,662 clean reads were assembled into 27,588 unigenes with a mean length of 768 nt. All unigenes were searched against the Nt database, Nr database, Swiss-Prot, Cluster of Orthologous Groups (COG and Kyoto Encyclopedia of Genes and Genome (KEGG with the BLASTn or BLASTx algorithm (E-value<0.00001 for annotations. In total, 7,081 unigenes and 14,099 unigenes were functionally classified into 25 COG categories and 240 KEGG pathways, respectively. Furthermore, 20,216 unigenes were grouped into 48 sub-categories belonging to 3 main Gene Ontology (GO categories (ontologies. Using the transcriptome data as references, we analyzed the differential gene expressions between a soybean oil-fed group (SOF and a lard oil-fed group (LOF, compared to the negative control group (NC, using the DGE approach. We finally obtained 1,566 differentially expressed genes in SOF/NC, and 1,099 genes in LOF/NC. For further analysis, GO and KEGG functional enrichment were performed on all differentially expressed genes, and a group of differentially expressed candidate genes related to lipometabolism were identified. CONCLUSIONS/SIGNIFICANCE: This study provides a global survey of C. megacephala and provides the basis for further research on the functional genomics of this insect.

    2014-07-01

    Call warrant is a type of structured warrant in Bursa Malaysia. It gives the holder the right to buy the underlying share at a specified price within a limited period of time. The issuer of the structured warrants usually uses European style to exercise the call warrant on the maturity date. Warrant is very similar to an option. Usually, practitioners of the financial field use Black-Scholes model to value the option. The Black-Scholes equation is hard to solve analytically. Therefore the finite difference approach is applied to approximate the value of the call warrant prices. The central in time and central in space scheme is produced to approximate the value of the call warrant prices. It allows the warrant holder to forecast the value of the call warrant prices before the expiry date.

    Full Text Available During the Ottoman period, cities were administrative units representing the existence of central authority and hegemony. It collected several activities and services within the domain and constituted a whole with its sub units in terms of administrative and civil duties. The development of city was dependent on the development of common life areas, which are neighborhoods. It was possible to see this structure, which is the basis of Ottoman urbanism, in Bursa, Edirne, Istanbul and some other Anatolian cities. Particularly Bursa has rapidly grown within the two centuries following the conquest and displayed a fine example of urbanization as a historical and cultural center. The idle fields in the city were allocated to Turkish tribes, new neighborhoods were established and the nearby villages were transformed into neighborhoods, increasing the total number of neighborhoods in the city. Beside this physical development, the newly established neighborhoods were given Turkish names as the old neighborhoods’ names were also made Turkish. Within this context, it was important to create a neighborhood in the localization of Bursa and the names given to those neighborhoods were also important. Because the names of places are the living documents for the habitation (settlement history of a nation. Studies to be conducted on neighborhood names are the research subjects of several social sciences such as sociology and anthropology and also the linguistics. Evaluation of the names of places phonetically and morphologically will contribute to the development of toponomy, which is an important branch of linguistics. This study has reviewed the neighborhood names in Hulâsatü’l-Vefeyât, a work of Gazzizâde Abdüllatif Effendi, which is considered as an urban monograph among the monographs on Bursa.

    In recent years, modeling in long memory properties or fractionally integrated processes in stochastic volatility has been applied in the financial time series. A time series with structural breaks can generate a strong persistence in the autocorrelation function, which is an observed behaviour of a long memory process. This paper considers the structural break of data in order to determine true long memory time series data. Unlike usual short memory models for log volatility, the fractional Ornstein-Uhlenbeck process is neither a Markovian process nor can it be easily transformed into a Markovian process. This makes the likelihood evaluation and parameter estimation for the long memory stochastic volatility (LMSV) model challenging tasks. The drift and volatility parameters of the fractional Ornstein-Unlenbeck model are estimated separately using the least square estimator (lse) and quadratic generalized variations (qgv) method respectively. Finally, the empirical distribution of unobserved volatility is estimated using the particle filtering with sequential important sampling-resampling (SIR) method. The mean square error (MSE) between the estimated and empirical volatility indicates that the performance of the model towards the index prices of FTSE Bursa Malaysia KLCI is fairly well.

    Full Text Available Adolescence is a transition phase from childhood to adulthood. In this period, rapid changes and development in their physical, biological, psychological, and social lives take place. While adolescents have to acquire many qualifications, they are faced with many problems, especially those that risk their health. In Turkey, one of the most important issues contributing to risky behaviors is the 1st Phase Nationwide High School Exam. Students must pass this phase in order to be in good high schools and to then pass the 2nd Phase University Exam. Most of their time is spent studying in school or in private teaching institutions, and less time is spent with their families or participating in social activities. In order to examine the effects on 9th grade students after the 1st Phase exams, we conducted this study with 1192 students in Bursa, Orhangazi. Data to evaluate students by socioeconomic status, body mass index (BMI, dietary, smoking, and physical activity behaviors and psychological status were collected via classroom questionnaires. We aimed to determine and evaluate the general characteristics and physical examination findings, to some extent, in a nationally representative sample of 9th grade students a year following the Nationwide High School Exam.

    International Nuclear Information System (INIS)

    Radiation mediated changes in nutritional profile of Spodoptera litura (Fabricius) were evaluated in relation to sublethal gamma doses causing partial to complete sterilization. Spodoptera larvae in the first, third and sixth instars were exposed to various gamma doses ranging from 0 to 7 Krad. The effects were more pronounced in the insect treated in their younger stages; the radiosensitivity declined with advanced age at irradiation. Consumption index (CI), for instance was 3.29 in control, but was reduced to 1.62, 1.75 and 1.91 at 4 Krad dose given to first, third and sixth instars, respectively. A sterilizing dose induced > 40 per cent reduction in AD in relation to control. Irradiation increased the net growth efficiency (ECD) but had no significant effect on gross growth efficiency (ECI).

Approach: As in the recent development of findings from Financial Statements Review Committee (FSRC that company did not disclose of Material expenses and not classified accordingly. Results: This study provides an evidence for the transparency level on income statements with regards of firms’ characteristics of 150 main and second boards companies listed on the Bursa Malaysia. The characteristics were grouped into three groups of variables: structural (firm size, leverage and number of shareholder, market related (listing type and industry type and performance (profit margin, return on equity and liquidity. The study was started with the development of a Transparency Index based on the percentage of the details of expenses disclosed in annual reports (notes to the accounts over the total expenses of the company. The findings suggested that this index on the average for the companies in the sample is about 64% with three companies scoring transparency index of 100%. Both univariate and multivariate statistical analysis were performed on the data. The stepwise regression method indicated that only one variable was significant at 5% which was the Number of Shareholders (LnNOSH. The other factors were not significant. Hence, this study will contributes to the enhancement of knowledge regarding income statements transparency and disclosure practices under new reporting regime in Malaysia. Conclusion/Recommendations: This study also served as a basis for further research in this area. This study also suggested that further research should be done on longitudinal study basis for several years of data with more appropriate or suitable variables to the model.

    Western Anatolia (Turkey) experienced widespread Cenozoic magmatism after the collision between the Sakarya and Anatolide-Tauride continental blocks in the pre-middle Eocene. The widespread magmatic activity in NW Anatolia postdates this continental collisional event in the region. The following magmatic episode during the Oligocene and Early Miocene is known to have produced the widespread granitic plutons. Many skarn mineralization associated with plutons formed in the region (such as Hayriye and Arapdede Mineralizations). The Paleozoic aged Devlez Metabasite is the oldest unit of the study area. This unit includes amphibolite, glaucophane-lawsonite schist, muscovite schists. The unit has widely spread in area. This units are overlain unconformably by the Geyiktepe Marbles. Paleocene aged Domaniç granitoidic intrusives cut other rock series and located as a batholite. Magmatic units present porphyric and holocrystalline textures. Granitoidic intrusions are represented by tonalite, tonalite porphyr, granodiorite, granodiorite porphyr, granite, diorite, diorite porphyries. The Domaniç granitoid intruded in to the metamorphides during Paleocene and caused formations of skarn zones and related Cu-Pb-Zn mineralizations along the contacts. Mineralizations are known in the locations named as Arapdede and Hayriye. The mineralizations occur along the metamorphites - plutonics contact, in the pockets and fractures extending towards marble. The thickness of the mineralized bodies can reach up to 1 -2 m. Primary minerals are galenite, magnetite, pyrite, chalcopyrite and sphalerite at Hayriye mineralizations and sphalerite, galenite, chalcopyrite and pyrite minerals at the Arapdede mineralizations.

    Full Text Available Adults and larvae of Leptotrachelus dorsalis (Fabricius, the Sugarcane Savior Beetle, live in association with grasses, the larvae in the appressed leaf axils. Both adult and larval L. dorsalis eat larvae of the Sugarcane Borer, Diatraea saccharalis (Fabricius, and perhaps other insects living in the confines of the leaf sheaths of that and other grass-like species. The geographic range of L. dorsalis extends from Kansas in the west to the Atlantic seaboard, north as far as Ontario, Canada and south to Cuba; it is an eastern species of North America and the Caribbean. Larval character attributes that are shared with a related ctenodactyline, Askalaphium depressum (Bates, provide a preliminary basis for characterization of the immatures of tribe Ctenodactylini.

    Full Text Available The effects of water and feed fasting for 24, 48 and 72 hours post-hatching on blood parameters (mean corpuscular volume, MCV; red blood-cell, RBC; hematocrit, HCT; hemoglobin, HGB; plasma glucose, CGP; plasma total protein, PP, and differential leukocytes count, and on body, liver, spleen, bursa, and yolk sac weights were analyzed. Erythrogram data were obtained with a blood cell counter. Total plasma protein and plasma glucose were determined by using the Bradford method (1976 and a glucose PAP liquiform kit (Labtest, cat. n. 84, respectively. Specific leukocyte counts were carried out on blood smears stained with Rosenfeld solution. According to the obtained data, water and feed post-hatching fasting reduced MCV values, which also were lower in males than that in females. Fasting for 48 hours promoted an increase in PP, while fasting for 72 hours reduced HCT. Chicks submitted to fasting presented lower body weights as compared to fed chicks, but their liver weight did not increase between 48 and 72 hours of age. Fasting decreased spleen weight, but bursa and yolk sac weight were not affected. Data showed that female and male chicks react in a similar way to post-hatching fasting, which affects body weight, liver and spleen weight, and HCT and PP values. Moreover, 72 hours of fasting affected more intensely HCT and MCV values.

    Full Text Available The primary function of artisans’ and commercial guilds was toperform and maintain daily activities of economic life in harmony andsocial consolidation with minimal conflict. Thus, the state would get ridof the heavy burden of bureaucratic procedures on the one hand, and yetwould also have the guilds yield to a standard of production as well aseliminate unfair competition through their autonomous internal workingson the other. Through such an auto-control mechanism the guilds wouldsolve their own problems with minimum resort to administrative andjudicial institutions. This article sheds light on the origins of Ottomanguild system, workings of trade guilds of Bursa and the supervisoryfunctions of their managers as well as on the various roles and activitiesplayed by the guilds in imperial public life. It also examines the conflictsof interest, unruly acts and forms of resolution taking place within andacross the guilds, with or without having recourse to judicial and otherimperial authorities. The study is based on a set of original historical documents surveyed from the Shari’a Court records of Bursa in the 16thand 17th centuries.

    The artificial diets mixed with various concentrations of nickel were offered to the larvae of the phytophagous insect Spodoptera litura Fabricius for 3 generations. Nickel accumulations in the 6th instar larvae, pupae and newly emerged adults of the corresponding generations of S. litura were investigated by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the effects of nickel accumulations on the survival rate of S. litura were also evaluated by individual rearing. The results showed that nickel accumulated in the 6th instar larvae, pupae and adults of S. litura, and the accumulated nickel in all the tested developmental stages within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependent relationship with the nickel doses in the artificial diets. The results also indicated that the nickel accumulations in the 6th instar larvae, pupae, and newly emerged adults from the 3rd generation were higher than those from the 2nd generation, which were also higher than those from the 1st generation. Nickel concentrations in pupae and adults were significantly lower than those in larvae, which indicated that the excessive nickel might be excreted during metamorphosis. Furthermore, larval survival rate, pupation rate and eclosion rate of S. litura in the tested three generations all decreased with the increase of the nickel doses in the treated diets.

    Behavioral and electrophysiological tests were performed to evaluate the responses of workers of the ant Solenopsis geminata (Fabricius) from different size categories to Dufour gland extracts. Morphometric measures based in head widths across eyes were used to determine worker sizes. Trail following response of different worker sizes to Dufour gland extract from workers of different sizes was assessed. For each worker size category olfactory responses to Dufour gland extracts were determined using electroantennography (EAG). Gas chromatography and mass spectrometry (GC-MS) were used to determine the chromatographic profile of Dufour gland secretion for each worker size. Morphometric measures permitted to classify the workers of S. geminata as large, medium and small workers. Medium S. geminata workers displayed a significantly higher behavioral response to Dufour gland extracts produced by medium size workers. Similarly, medium workers showed a significantly higher EAG response to Dufour gland extracts produced by medium sized workers. Chromatographic profile of Dufour gland secretions produced by workers showed that each size category exhibited a characteristic profile of the three main components considered as potential trail pheromone constituents. This work showed that medium workers of S. geminata exhibited a high trail-following behavior as well as a high antennal response to Dufour gland secretion. This and their relative abundance in field foraging areas, suggest that medium-sized workers are specialized in foraging activities. (author)

  10. Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabricius larvae exposed to nickel

    Metallothionein expression induced by nickel accumulation in the midgut of Spodoptera litura Fabricius larvae was investigated by exposing S. litura larvae to the artificial diets amended with different doses of nickel for 3 generations. Nickel accumulations in the midgut of 6th instar larvae were detected by Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and the induced metallothionein expression in the midgut of 5th and 6th instar larvae in 120 h were quantified using cadmium-hemoglobin total saturation methods. The accumulated nickel in the midgut of the 6th instar larvae within a generation increased with the increase of the nickel doses in the treated diets and showed significant dose-dependence with the nickel doses in diets. Metallothioneins induced by nickel accumulated in the larval midgut also increased with nickel doses in diets and with the increasing stressing time in a generation. Results also suggested that the metallothionein expression was different with the time of S. litura larvae stressed by nickel.

    Full Text Available Of major importance in realizing the potential of edible insects as a core element in improving food security, sustainable food production, and biodiversity conservation, are developments in sustainable exploitation of wild edible insect populations and in (semi-cultivating and farming edible insects. Such developments can draw on both western science and indigenous knowledge. Oecophylla smaragdina Fabricius Hymenoptera: Formicidae, of which particularly the queen brood is commonly consumed in Thailand and the Lao PDR, is believed to have the potential to act as flagship/umbrella species in forest conservation and management, to be incorporated simultaneously as biological control agent and direct source of human food in agroforestry practices, and to be (semi-cultivated. We provide a detailed account of indigenous knowledge of O. smaragdina and ant brood collection practices from the Vientiane Plain, Lao PDR, through focus group discussions and participant observations, and then reflect on sustainability and conservation issues, and on semi-cultivating constraints and possibilities embedded in indigenous knowledge and ant brood collection practices.

    Insect specimens collected from decomposing bodies enable forensic entomologists to estimate the minimum post-mortem interval (PMI). Drugs and toxins within a corpse may affect the development rate of insects that feed on them and it is vital to quantify these effects to accurately calculate minimum PMI. This study investigated the effects of morphine on growth rates of the native Australian blowfly, Calliphora stygia (Fabricius) (Diptera: Calliphoridae). Several morphine concentrations were incorporated into pet mince to simulate post-mortem concentrations in morphine, codeine and/or heroin-dosed corpses. There were four treatments for feeding larvae; T 1: control (no morphine); T 2: 2 microg/g morphine; T 3: 10 microg/g morphine; and T 4: 20 microg/g morphine. Ten replicates of 50 larvae were grown at 22 degrees C for each treatment and their development was compared at four comparison intervals; CI 1: 4-day-old larvae; CI 2: 7-day-old larvae; CI 3: pupae; and CI 4: adults. Length and width were measured for larvae and pupae, and costae and tibiae were measured for adults. Additionally, day of pupariation, day of adult eclosion, and survivorship were calculated for each replicate. The continued presence of morphine in meat was qualitatively verified using high-performance liquid chromatography with acidic potassium permanganate chemiluminescence detection. Growth rates of C. stygia fed on morphine-spiked mince did not differ significantly from those fed on control mince for any comparison interval or parameter measured. This suggests that C. stygia is a reliable model to use to accurately age a corpse containing morphine at any of the concentrations investigated.

    Body melanisation in insects is polygenic, resulting from genetic polymorphism or phenotypic plasticity, with diverse implications ranging from thermal budgeting to reproductive success. In this study, we assessed the, mate choice, reproductive success, and offspring colouration of typical (T) and melanic (M) morphs of the ladybird Menochilus sexmaculatus paired at three temperatures 15°C, 25°C and 35°C. Mating success of the two morphs and the consequences for offspring fitness and offspring phenotype under these temperature regimes were evaluated. Melanic adults of both sexes achieved significantly higher mating success at 15°C and 25°C, but at 35°C no influence of adult morph on mate selection was observed. Melanic females were more fecund than typical females at all temperatures. Offspring of melanic parents developed faster than those of typicals at 15°C and 25°C, but not at 35°C. Evidence was also found of phenotypic plasticity in colour form at 15°C and 35°C. At 25°C the parents of pure (T) and (M) morphs produced offspring of the same morph. However, low temperature induced partial melanisation among the offspring of typical parents (T). Whereas at 35°C the offspring of (T) parents became paler in colour with very fine zigzag lines on elytra, i.e. they decrease the degree of melanisation. Pure melanics (M) compensated for elevated temperature stress by producing offspring that were either pure melanic but small or large with reduced melanisation. Our results on offspring phenotype variation indicate that the degree of melanism in morphs is a result of environmentally regulated expression of the parental genotype. PMID:27157332

    Full Text Available α-amylase is one of the enzymes that has crucial role in extra-oral digestion (EOD of hemipteran insects. An α-amylase was purified and biochemically characterized from the salivary glands of Andrallus spinidens showing its considerable role in EOD process. It was found an enzyme by specific activity of 4.22 U/mg protein, recovery of 14.67 % and purification fold of 13.83-fold as well as molecular weight of 26 kDa. By using two buffer solutions, optimal pH of the purified α-amylase was found to be 9 for both universal and Tris-HCl buffers. Our findings revealed that the purified α-amylase had the highest activity at the temperatures of 35 and 40 °C, and were stable for 96 h at these temperatures. Kinetic parameters of the purified enzyme show that both starch and glycogen, are the suitable substrates for the enzymatic assay, but a lower Km demonstrated glycogen as a more appropriate substrate. Among the cations used to show their possible involvement in active site of the enzyme, Ca2+2+, Mg and one concentration of Cu2+ increased the α-amylase activity but Na+ decreased the enzyme activity. Triton X-100 increased the enzyme activity but SDS, EDTA, EGTA and TTHA decreased it, indicating involvement of metal ions in the active site of the purified α-amylase.

    The structurally diverse rocky shores along the northern coast of the state of São Paulo, Brazil, support a varied fauna and provide refuges for many organisms. Some of these environments allow for extensive microhabitats, among them the sand reefs formed by the polychaete Phragmatopoma lapidosa, which occupy much of this area. The beauty of the landscape attracts large numbers of tourists, who contribute to the damage to the sand reef colonies, causing an imbalance in the patterns of population distribution and of this ecosystem. We describe the structure and population biology of the redfinger rubble crab Eriphia gonagra, and investigated the differential occupation of the habitat by each demographic category of this species. Crabs were sampled monthly for two consecutive years on the rocky coast of Grande Beach, Ubatuba, São Paulo, during spring low tides. Sampling was carried out over an area of approximately 1200 m2, during two hours on the rock surface and another two hours on the sand reefs. A total of 1407 crabs were collected; 776 on the sand reef (SR) and 631 on the rocky shore (RO). The majority of juvenile crabs inhabited the SR, while adult crabs were equally distributed in both microhabitats. This study showed that the SR is a natural nursery ground for the establishment of the early juvenile stages of E. gonagra, which use the reefs as a refuge and food resource. Many other organisms (mollusks, echinoderms, polychaetes etc.) settle on the reefs, and these areas may be among the most important in maintaining benthic diversity in the region. PMID:25296208

  6. Application of Irradiated Pro biotic Microorganism in Black Tiger Shrimp (Penaeus monodon Fabricius) Culture

    International Nuclear Information System (INIS)

    Marine shrimp culture in Thailand has been developed continuously for the past two decades. This development will ensure the highest level of shrimp quality that will be suitable for the consumption of the people in the country and also aboard. The trend of culture system emphasizes on disease prevention more than treatment which will consequently limit the application of drug and chemicals. Application of pro biotic has been one means of this prevention that are commonly practiced by shrimp farmers. This research was conducted to compare the efficacy of normal Bacillus subtilis isolate from shrimp intestine and an irradiated B. subtilis as a pro biotic in shrimp feed. It was found that overall results were quite the same. These included the broth Co-culture assay. Effects on immune functions were conducted with Penaeus monodon with initial average weight of 17 gms by feeding with 3 gms/kg feed of spore of these two pro biotic for two mouths. The results indicated that both pro biotic caused significant improvement on percent phagocytosis only at the forth week of feeding trial and the overall enhancement of bactericidal activity. However, total haemocyte count and phenoloxidase activity were not altered. Total bacterial count in shrimp intestine was also conducted during the two month trial. the results indicated significant reduction of Vibrio spp. of both pro biotic groups when compared with the control. Number of Bacillus spp. in intestine were continuously high even after pro biotic treatment had been stopped Growth rate of experiment and control shrimp was not significantly different.

    The giant honeybee Apis dorsata often forms dense colony aggregations which can include up to 200 often closely related nests in the same location, setting the stage for inbred matings. Yet, like in all other Apis species, A. dorsata queens mate in mid-air on lek like drone congregation areas (DCAs) where large numbers of males gather in flight. We here report how the drone composition of A. dorsata DCAs facilitates outbreeding, taking into the account both spatial (three DCAs) and temporal (subsequent sampling days) dynamics. We compared the drones' genotypes at ten microsatellite DNA markers with those of the queen genotypes of six drone-producing colonies located close to the DCAs (Tenom, Sabah, Malaysia). None of 430 sampled drones originated from any of these nearby colonies. Moreover, we estimated that 141 unidentified colonies were contributing to the three DCAs. Most of these colonies were participating multiple times in the different locations and/or during the consecutive days of sampling. The drones sampled in the DCAs could be attributed to six subpopulations. These were all admixed in all DCA samples, increasing the effective population size an order of magnitude and preventing matings between potentially related queens and drones. PMID:25558361

    Full Text Available Spodoptera litura is a notorious leaf feeding insect pest of more than one hundred plants around the Asia-Pacific region. Host plant survey for two years from three different locations in cotton belt revealed 27 plant species as host plants of S. litura belonging to 25 genera of 14 families including cultivated crops, vegetables, weeds, fruits and ornamental plants. Major host plants on which it thrived for maximum period were Gossypium hirsutum L., Ricinus communis L., Brassica oleracea var. botrytis L., Colocasia esculenta L., Trianthema portulacastrum L. and Sesbania sesban L.. Eggs were also collected from tree plants but larvae did not complete their development. Reliance of S. litura on major plant species of cultivated crops necessitates their regular monitoring especially during March to April for their population abundance and early warning for their management on commercial crops like cotton.

  11. Progress in the eradication of Amblyomma variegatum Fabricius, 1794 (Ixodoidea, Ixodidae) from the Caribbean

    International Nuclear Information System (INIS)

    Amblyomma variegatum, commonly known as the tropical Bont tick, was introduced from West Africa to the islands of Guadeloupe and Antigua in the 19th century. The tick spread only to two other islands in the French West Indies during the following 70 to 80 years. Since the mid-1970s, however, it became widely distributed in the eastern Caribbean islands. There is now increasing evidence that migratory birds, especially the cattle egret, Bubulcus ibis Linnaeus (Ciconiformes: Ardeie) disseminated larvae and nymphs, as the egret itself has been spreading to new islands over the last 20 years (Corn et al. 1993, Barre et al. 1995). Subsequently, the tropical Bont tick, through its association with the bacterial skin disease known as dermatophilosis, caused the loss of large numbers of animals. On Nevis, for example, cattle numbers were decimated from 5,000 to 500 in less than 10 years. Elimination of this tick and its associated diseases could help to alleviate the deficit in animal protein in the region which imports about US$100 million worth of livestock products per annum. Risk analysis, feasibility and cost-benefit studies were carried out to assess the importance of these problems (Alderink and McCauley 1988, Gersabeck 1994). The US Department of Agriculture estimated potential losses of US$762 million annually if the tick and its associated diseases became established in mainland countries. These studies led to the formulation of the Caribbean Amblyomma Programme in the late 1980s (Barre and Garris 1989, CARICOM/FAO/IICA 1995, Wilson 1996). During the early 1990s, potential donors were concerned about the proposed tick control strategy whereby government veterinary teams would be responsible for treatment of all livestock. Based on practical experience in the region, it was considered particularly unrealistic for teams to treat 600 - 1,000 animals per day under the current livestock management practices. An alternative, or complementary, method proposed the use of

In the first method, which was qualitative, the exuviae were classified by scoring the degree of melanization, whereas in the second method, which was quantitative, the exuviae were classified by optical density followed by analysis with appropriate software. The heritability (h 2 of the degree of melanization was estimated by regression and analysis of variance. The estimates of h 2 were similar with both methods, indicating that the qualitative method could be particularly suitable for field work. The low estimates obtained for heritability may have resulted from the small sample size ( n = 7-18 broods, including the parents or from the allocation-priority hypothesis in which pupal color would be a lower priority trait compared to morphological traits and adequate larval development.

    The mite Ornithonyssus bursa (Berlese) (Mesostigmata: Macronyssidae) is considered a poultry pest causing important infestations in chickens and it is considered a potential vector of arbovirus. Despite being considered a common parasite in wild birds, there is scarce published information about its potential hosts and effects on them. Here we present new bird hosts for O. bursa, assess the presence of Alphavirus, Flavivirus and Bunyavirus in mites from three host species, and discuss its potential impact on wild bird populations. We found O. bursa infecting five raptor and six passerine wild bird species. For nine of these species, this is the first record of infection by O. bursa. Although all analysed mites were negative for the examined arboviruses, the small sample size of mites does not allow further conclusions at the present moment. Because of the general nature of this ectoparasite, its presence in migratory long dispersal and endangered bird species, and the seropositivity for arboviruses in some of the species studied here, we consider it critical to assess the role of O. bursa and other ectoparasites as vectors and reservoirs of pathogens and as potential deleterious agents in wild bird populations.

    Full Text Available This project was aimed to evaluate immunostimulatory effects of three therapeutic substances in broilers suffering from infectious bursal disease (IBD. For this purpose, 150 chicks were divided into five equal groups i.e. A, B, C, D and E having 30 birds each. Group A, B, C and D were challenged with infectious bursal disease virus. There were three immunostimulatory treatments i.e. levamisole (group A, vitamin E (group B, and bursinex (group C. Groups D and E were untreated control. Bursa body weight index, histopathology of bursa of Fabricius, plasma cell counting in Harderian gland and estimation of antibody response against infectious bursal disease virus was recorded. Vitamin E played a major role in improving the condition of birds suffering from infectious bursal disease, as it showed increased bursa body weight index (BBIx, less histopathological lesions in bursa of Fabricius, increased number of plasma cells in Harderian gland and high antibody response in infectious bursal disease infected broilers as compared to levamisole and bursinex. Levamisole played a minor role in improving condition of birds, while bursinex did not seem to be much effective against infectious bursal disease virus in this study.

    Full Text Available The fig fruit is a unique, climacteric, highly perishable subject to rapid physiological breakdown. Application of 1-methylcyclopropene (1-MCP was tested to delay ripening of black fig (Ficus carica L. cv. ‘Bursa Siyahi’ during storage over two growing seasons. Fruits were pre-cooled to 1 °C for 6 hours and afterwards treated with 500 or 1000 nl l-1 of 1-MCP for 24 hours. Treated fruits were stored for 10 days at 1 °C, 90-95% RH and then evaluated. 1-MCP treatments showed that ethylene production, respiration rate, weight loss and concentrations of glucose, fructose and total soluble solids (TSS were negatively correlated to the 1-MCP doses during cold storage (with the exception of TSS in the first year of experiment and respiration rate in the second year of the experiment. In contrast, pulp firmness and colour (ho during cold storage were positively correlated to the 1-MCP applied doses. Results of this study showed that although 1-methylcyclopropene applications slowed down fruit softening during the 10 days of storage, 1-methylcyclopropene appeared to have a relatively limited effect on slowing ripening ofBursa Siyahi’ figs.

    In rearing of Gangara thyrsis (Fabricius) (Lepidoptera: Hesperiidae) from Karnataka and Goa, India, six species of parasitoids were observed. One new species of parasitic wasp is described and illustrated: Agiommatus thyrsisae n. sp. (Hymenoptera: Pteromalidae), a solitary parasitoid reared from the egg of G. thyrsis on the natural host plant Dypsis lutescens (H. Wendl.) Beentje & J. Dransf. Three additional species of parasitic wasps were also reared: Anastatus ramakrishnai (Mani, 1935) (Hymenoptera: Eupelmidae), a solitary hyperparasitoid of A. thyrsisae n. sp.; Sympiesis thyrsisae Gupta, Gawas & Bhambure (Hymenoptera: Eulophidae), a gregarious parasitoid reared from the caterpillar of G. thyrsis on the host plant Cocos nucifera L., and Brachymeria lasus (Walker) reared from pupa of G. thyrsis on the host plant D. lutescens. Additionally, two species of tachinid flies were also reared from the pupae of G. thyrsis: Exorista sorbillans (Wiedemann, 1830) and an innominate species close to Blepharella spp. Gangara thyrsis is a new host record for the genus Agiommatus and for A. ramakrishnai and B. lasus. The mean percent parasitism in G. thyrsis eggs was 26.58% with an incubation period of 6-7 days. Amongst the egg parasitoids, 57.14-73.08% were females and 23.08% were males. Hyperparasitism ranged from 3.85 to 42.86%. Dypsis lutescens, a member of Arecaceae, is a new host plant record for G. thyrsis. PMID:27307173

    Full Text Available Oviposition site selection of Heliconius erato phyllis (Fabricius, 1775 (Lepidoptera, Nymphalidae was studied when size of and damage on shoots were variable in a natural population of Passiflora suberosa Linnaeus (Passifloraceae, and through sequential and simultaneous choice experiments performed under insectary conditions. Females showed marked oviposition preference for undamaged and largest shoots of P. suberosa. Eggs were mostly laid on the terminal buds of intact shoots under natural conditions. In simultaneous choice trials, females preferred to oviposit on shoots from which leaves (ten were removed but the terminal bud maintained to those where leaves were kept but the terminal bud was cut out. In sequential choice trials, they did not lay eggs on shoots from which the terminal bud was removed. Females preferred to oviposit on large to short intact shoots in both sequential and simultaneous choice trials. Females laid eggs preferentially on shoots with the greatest leaf area when most plants were intact in the field during early spring. Later in fall, when mostly large, old shoots were damaged or in a reproductive stage (less desirable for oviposition, oviposition intensity was highest on the shortest, youngest shoots of P. suberosa. Thus, females might rank these quality attributes higher than size while selecting shoots for oviposition. The consequences of ovipositing selectively on intact, large shoots of P. suberosa are discussed from the view point of H. erato phyllis larval performance.

Among the ixodids observed (A. cajennense; A. dissimile Koch, 1844; Rhipicephalus sanguineus Latreille, 1806; Anocentor nitens (Neumann, 1897 Schulze, 1937; Boophilus microplus Canestrini, 1887 and Haemaphysalis sp. only A. cajennense was different in the adult hemolymph colour. It changed from amber to deep blue as the ixodid age advanced. This fact could be associated with the presence of hemocyanin in the hemolymph and points out the need to develop further investigations about the Ixodidae hemolymph pratein composition as well as the function of all the types found in it. This information could aid the studies on ticks control.

    Full Text Available The sublethal effects of diazinon, fenitrothion and chlorpyrifos on the functional response of predatory bug, Andrallus spinidens Fabricius (Hem.: Pentatomidae, a potential biological control agent, were studied on 5th-instar nymphs. The experiment was conducted in varying densities (2, 4, 8, 16, 32 and 64 of last instars larvae of Chilo suppressalis Walker (Lepidoptera: Pyralidae as prey at 25 ± 2 °C, 60% ± 10% relative humidity (RH and a photoperiod of 16:8 h (L: D. The results of logistic regressions revealed a type II functional response in the control and all insecticide treatments. Comparison of functional response curves revealed that tested insecticides markedly decreased the mean of preys consumed by A. spinidens. Among them, functional response curve of A. spinidens in chlorpyrifos treatment was significantly lower than the other treatments. In this study, application of insecticides caused a decrease in the attack rate and an increase in the handling time of exposed bugs compared with the control. The longest handling time (3.97 ± 0.62 and the lowest attack rate (0.023 ± 0.007 were observed in chlorpyrifos and fenitrothion treatments, respectively. The results suggested that the adverse effect of these insecticides on A. spinidens should be considered in integrated pest management programs (IPM.

    Some beetles are as useful as blow flies for estimating the minimum post mortem interval (PMImin) or time since death. Examples include Thanatophilus micans (Fabricius) and Thanatophilus mutilatus (Castelneau), two geographically and ecologically overlapping African beetles. Molecular means of identifying these species, descriptions of their natural history, thermal summation models for the development of each species, and a case in which T. micans was recovered are presented. These beetles colonise bodies soon after death, their development spans more time than that of flies, and they may be little affected by maggot-generated heat. From an experimental perspective, they can be reared individually, which allows the identification of sick individuals and has analytical advantages relative to fly larvae that must be reared in groups. Estimating minimum post mortem intervals for both species using the case data strongly suggests that developmental models parameterised for one species should not be used to make forensic estimates for closely related species for which no specific model is available and emphasises the need for correct identifications.

Materials and methods: We evaluated MRI of 165 shoulders in 48 consecutive patients with a diagnosis of shoulder adhesive capsulitis in the freezing phase (group I), in 49 short-wide superior cuff tear (group II) and in 65 controls (group III) between 2010 and 2013. On the T2 weighted images, we evaluated the presence of an high intensity signal within the superior subscapularis recess, consistent with fluid distension of the bursa. Results: The sign was found in 43/48 patients (89.58%) with shoulder adhesive capsulitis in 3/49 (6.12%) patients with superior cuff tear and in 1/65 controls (1.53%) (p < 0.001). The mean diagnostic values were: sensibility 0.91; specificity 0.96–0.98; positive predictive value 0.93–0.97; negative predictive value 0.92–0.94; likelihood ratios for an abnormal test result 15.16–60.6; likelihood ratios for a normal test result 0.086–0.095. Conclusion: For the orthopedic surgeon or the clinician, the sign is useful to confirm in MRI the clinical diagnosis of shoulder adhesive capsulitis; accordingly, the radiologist should describe and relate this sign to the pathology in the report, looking eventually for further typical sign of shoulder adhesive capsulitis.

    Full Text Available The overall appearance and size are the most effective factors for quality determination of olives. Moreover, quality classification and pricing of olives are done according to size namely the number of olive fruits per kilogram. The aim of this study was to designate the effects of some quality criteria: number of olive fruit/kg (188-363, width (14.23- 19.23 mm, height (18.23-24.17 mm, flesh/stone weight ratio (4.80-6.96 , total dry matter (41.27-47.19 %, total acidity as lactic acid (0.53-0.74 %, pH (5.10-5.29, total oil (21.70-26.77 %, fatty acid composition of raw table olives on price determination by hedonic model analysis. Statistical analysis of prices was done by using average retail prices of the samples. Lactic acid, flesh/stone weight ratio, total oil and linoleic acid factors had positive coefficients, so they positively affected the price. According to this model, main quality criteria affecting the price of olives were total acidity and flesh/stone weight ratio. Other factors did not significantly affect the table olive price. Especially the latter, since for the consumers, paying more would not only mean larger fruits but also a higher flesh ratio. Also, considering the factors having positive coefficients in price determination of table olives for both producers and consumers was important.

    Recently (2013-2014), several hoverfly specimens from two localities in Benin and Cameroon (West and Central Africa) were caught from a species that we could not identify using existing identification keys for Afrotropical Syrphidae. Specific identification as Toxomerus floralis (Fabricius) was accomplished using morphology and various Neotropical identification keys. Corroboration of this identification was made by sequencing of the standard COI barcode region and a subsequent BLAST-IDS in BOLD that revealed a 100% sequence similarity with Toxomerus floralis from Suriname (South America). Species identification was further supported by sequencing parts of the nuclear 18S and 28S rRNA genes. The species is widespread in Togo, Benin, Nigeria and Cameroon, and eggs, larvae and adults are abundant at several localities. Yet, the full extent of its geographic distribution within tropical Africa remains to be determined. This is only the second known established introduction of a non-African hoverfly species in the Afrotropics. Interestingly, the larvae of the species have been reported as predators of Aphididae and Delphacidae but we found them to be pollenivorous, which is a rare feeding mode within the subfamily Syrphinae. Moreover, it is the only known Syrphinae species of which the larvae feed on pollen from two plant species from different families (Cyperaceae and Orobranchaceae). This example illustrates how DNA barcoding may allow a fast and accurate identification of introduced species.

    Full Text Available Benjamin Graham, also known as the “father of value investing” proposed that investment in the stock exchange can be a safe endeavor while receiving gains that outperform the market if the investor makes carefully thought out purchases. This study aims to determine if the use of some of Benjamin Graham’s stock selection criteria is able to generate returns that are significantly greater than the returns in the stock exchange of Malaysia, particularly, the comprehensive FTSE Bursa Malaysia EMAS Index. This study collected secondary data regarding fundamentals of companies listed in the FTSE Bursa Malaysia EMAS Index from the year 2000 to 2009. Five criteria were set up in this research based on one or a combination of price-to-earnings ratio, price-to-book value, current ratio and dividend yield. The listed companies were screened using those criteria. An equally weighted portfolio was created using the screened companies and their one-year and two-year returns calculated. The returns were compared to the market return. Hypotheses of this research were tested using t-test statistic to determine the significance of the data. This research found that most of the screening criteria used generated returns that were higher than the market return in almost every year they were tested in. Benjamin Graham’s stock selection criteria although have been conceived over 80 years ago is still applicable today in the Malaysian market. Further research can be conducted with different criteria with varying holding periods and in different markets.

  17. Hydro geochemistry Investigation of The (Bursa) Orhangazi Plain and its Environs

    International Nuclear Information System (INIS)

    The study area is located SE of the Armutlu Peninsula. Geological and hydrogeological studies are conducted on 1/25.000 scale maps covering an area of approximately 70 km2. The basement of the region is made up of metagreywacke shale and schist which are overlain by marbles with the extensive karstic features such as caves, polya, etc. The Pliocene aged lacustrine unconformably overlying the marbles are covered with alluvium in Orhangazi plain. At present, the Nadir and Kaynarca springs supply water for the town of Orhangazi. The Nadir spring flows naturally towards the municipality water system whereas the Kaynarca spring water is pumped into the system. These springs are naturally fed by precipitation through the marbles. In order to investigate the velocity of these water sources in the specified direction and their relation with each other, experiments of dye trace, water chemistry and isotopic analyses from hydrochemical point of view were conducted. Based on these observations, it was found that the source area of the Kaynarca and Ilipynar spring waters were to the east and south of the source area of the Nadir spring and that there was no connection between the sources of water to Nadir spring and that of the other two springs. Also, the predominant ions in the source waters are Ca+2 and HCO3-. These are of meteoric origin that are under the effect of annual rains. The effects of the Marmara 17 Agust Earthquake were relatively minor although temporary changes in flow and turbidity occured almost immediatly after the earthquake. The earthquake did not alter the chemistry of the water springs

    Full Text Available Objective: In this study, antimicrobial activities of an ethanol extract of Tribulus terrestris aloneand in combination with Capsella bursa-pastoris and Glycyrrhiza glabra were examined in vitro against six pathogens namely Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus, Enterococcus faecalis Staphylococcus aureus, and Escherichia coli. Materials and methods: Antibacterial activities of the extracts were examined using disc and well diffusion methods and the minimum inhibitory concentration (MIC and minimum bactericidal concentration (MBC of ethanol extracts were determined against these microorganisms using agar and broth dilution methods. Chlorhexidine was used as positive control. Results: Tribulus terrestris extract exhibited good antibacterial activity against all bacteria. Antibacterial activity of mixed extract was evaluated and exhibited that mixed extract was more effective against all bacteria than any of the cases alone which indicates the synergistic effect between these three extracts (p˂0.05. No strain showed resistance against these extracts. In agar dilution, Tribulus terrestris exhibited MIC values ranging from 35.0 to 20.0 mg/ml and mixed extract showed MIC values ranging from 12.5 to 5.0 mg/ml. The results of broth dilution method were consistent with the findings of the agar dilution method. Conclusion: This in-vitro study was a preliminary evaluation of antibacterial activity of the plants. It provided scientific evidence to support uses of T. terrestris and its mixture with C. bursa-pastoris and G. glabra for the treatment of oral infections. In-vivo studies are also required to better evaluate the effect of these extracts.

    Full Text Available Micraspis discolor (Fabricius (Coleoptera: Coccinellidae is a widely distributed coleoptera predator in southern Asia in rice ecosystem, and adult M. discolor feed on both rice pollen and soft-bodied arthropods. Bitrophic bioassay and tritrophic bioassay were conducted to evaluate the potential impact of Cry1Ac/Cry1Ab-expressing rice Huahui 1 and its non-transgenic counterpart Minghui 63 on fitness parameters of adult M. discolor. The results showed that the survival, and fecundity of this beetle' adults were not different when they fed on Bt rice or non-Bt rice pollen or Nilaparvata lugens (Stål reared on Bt rice or non-Bt rice. Toxicity assessment to ensure M. discolor adults were not sensitive to Cry1Ab or Cry1Ac protein independent from the pollen background, M. discolor adults were fed with an artificial diet containing Cry1Ac, Cry1Ab or both protein approximately 10 times higher concentration than in Huahui 1 rice pollen. No difference was detected for any of the life-table parameters tested between Cry protein-containing and pure diet. Artificial diet containing E-64 (N-(trans-Epoxysuccinyl-L-leucine 4-guanidinobutylamide was included as a positive control. In contrast, the pre-oviposition and fecundity of M. discolor were significantly adversely affected by feeding on E-64-containing diet. In both bioassays, the uptakes of Cry protein by adult M. discolor were tested by ELISA measurements. These results indicated that adults of M. discolor are not affected by Cry1Ab- or Cry1Ac-expressing rice pollen and are not sensitive to Cry protein at concentrations exceeding the levels in rice pollen in Huahui1. This suggests that M. discolor adults would not be harmed by Cry1Ac/Cry1Ab rice if Bt rice Huahui 1 were commercialized.

    Full Text Available Lygus rugulipennis Poppius and Liocoris tripustulatus Fabricius (Heteroptera: Miridae are pests of glasshouse cucumber and sweet pepper crops respectively. L. rugulipennis has a wide range of foodplants, but L. tripustulatus is specialised with very few food plants. We report behavioural assessments to investigate whether either species exhibits a preference for salad over wild hosts, and whether the role of olfaction and vision in response to cues from host plants can be distinguished. Olfactory responses to leaves were tested in choice chambers. L. rugulipennis was presented nettle (wild host and a salad leaf of cucumber or sweet pepper, where the salad leaves had higher nitrogen content. L. tripustulatus was tested with nettle and sweet pepper of two different nitrogen contents. Female L. rugulipennis spent more time on the cucumber salad host, and chose it first most often, but males showed no preference. Neither sex discriminated between sweet pepper or nettle leaves, but males made more first contacts with sweet pepper. Neither sex of L. tripustulatus discriminated between sweet pepper and nettle leaves when the sweet pepper had higher nitrogen. When the plant species contained equivalent nitrogen both sexes spent more time on nettle. There was no difference in first choice made by either sex. When visual stimuli were available, and leaves had equivalent nitrogen, L. rugulipennis showed no preference and L. tripustulatus preferred nettle leaves. We conclude that the generalist L. rugulipennis has the ability to use remote olfactory cues for host choice whereas the specialist L. tripustulatus relies mainly on contact chemosensory and gustatory cues.

    Chemoreception is a key feature in selection of host plant by phytophagous insects, and odorant-binding proteins (OBPs) are involved in chemical communication of both insects and vertebrates. The legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae) is one of the key pest species of cowpea and widely distributed throughout tropical and subtropical regions, causing up to 80% of yield loss. In this study, we investigated the electrophysiological responses of female M. vitrata to floral volatiles from V. unguiculata. Seventeen electroantennogram-active compounds were identified from floral volatiles of V. unguiculata by coupled gas chromatography-electroantennography (GC-EAD) and gas chromatography-mass spectrometry (GC-MS). Then, we cloned two novel full-length GOBP genes (MvitGOBP1 and MvitGOBP2) from the antennae of M. vitrata using reverse transcription PCR. Protein sequence analysis indicated that they shared high sequence similarity with other Pyralididae insect GOBPs and had the typical six-cysteine signature. Real-time PCR analysis indicated that MvitGOBP1-2 mRNA was highly expressed in the antennae of female adult with several thousands-fold difference compare to other tissue. Next, the recombinant MvitGOBP1-2 was expressed in Escherichia coli and purified using Ni ion affinity chromatography. Fluorescence binding assays demonstrated that MvitGOBP1-2 had different binding affinities with 17 volatile odorant molecules including butanoic acid butyl ester, limonene, 4-ethylpropiophenone, 1H-indol-4-ol, butanoic acid octyl ester and 2-methyl-3-phenylpropanal. In the field trapping experiment, these six floral volatiles could effectively attract female moths and showed significant difference compared with the blank lure. These results suggested that MvitGOBPs and the seventeen floral volatiles are likely to function in the olfactory behavior response of female moths, which may have played crucial roles in the selection of oviposition sites.

  13. Chemo sterilization of the sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) with sugar solution bait and insecticides of insect growth regulators group

    International Nuclear Information System (INIS)

    The sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is an important pest in Brazilian sugarcane crops. Currently, biological control is the most frequently used method for controlling D saccharalis. However, in several locations, the parasitoid Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) has not been effective for controlling this pest, and it has been recorded infestation intensity above 25%. In this context, the Sterile Insect Technique could be an additional control method in Integrated Pest Management, because it is compatible with other control methods. The use of insecticides that interferes in hormone homeostasis involved in the ecdyse's process with exogenous hormone sources or synthetic analogues (agonists or antagonists) can result in the interruption of the reproductive process or abnormal development of the insect?s embryo. Then, the objective of this study was to evaluate the insecticides that regulates the insect growth on the D. saccharalis reproduction. The insecticides tested were: chlorfluazuron (1,0 and 1,5 g a.i./L), diflubenzuron (3,75; 5,0 and 7,5 g a.i./L), flufenoxuron (1,0 g a.i./L), lufenuron (0,75; 1,0 and 2,0 g a.i./L), novaluron (0,5 and 1,0 g a.i./L) pyriproxyfen (1,0; 1,5; 1,8 and 2,0 g a.i./L) and teflubenzuron (1,5; 3,0 and 6,0 g a.i./L). Each insecticide was provided to 1-day moths on soaked cotton with a sugar solution at 10% as a bait. All treatments, except to of the lowest concentration of lufenuron (0,75 g a.i./L) decreased the egg production in relation to the control. Flufenoxuron (1,00 g g a.i./L) and chlorfluazuron (1,50 g a.i./L) decreased the lifespan of both sexes treated by ingestion. Lufenuron (2,0 g a.i./L), novaluron (1,0 g a.i./L) and teflubenzuron (3,0 g a.i./L) decreased the male's lifespan. The most effective treatments for sterilization were pyriproxyfen (1,8 g a.i./L and 2,0 g a.i./L) and lufenuron (2,0 g a.i./L), witch showed efficiencies greater or close to 80

    Full Text Available Mahakam Delta area, which is situated in Kutai Kartanegara Regency, has become a pond center that gives a significant contribution to shrimp export of East Kalimantan Province. Pond-produced shrimps, however, do not always accord to the intention of cold storage companies at expected price. The companies even sometimes reject the request due to poor quality of the product. The decreasing shrimp quality may be due to maintenance process by the pond farmers as well as the improper collectors. In the other hand, importing countries have decided more and more restricted requirements for the imported fishing products. This study was held in Muara Jawa, Anggana, and Muara Badak Districts using techniques of data collection of in-depth interview with twelve respondents. In order to improve shrimp quality, farmers or the producers have to formulate a strategy towards the improvement of the post harvest shrimps from the pond using an Analytical Hierarchy Process (AHP.

    Full Text Available Blowflies use discrete and ephemeral substrates to feed their larvae. After they run out of food, the larvae begin to disperse in order to find adequate places for pupation or additional food sources, a process named post-feeding larval dispersion. Some important aspects of this process were studied in a circular arena allowing the combined radial post-feeding dispersion from the center of the arena of C. albiceps and C. megacephala larvae. To determine the location of each pupa, the arena was divided in 72 identical sections starting from the center. The distance from the center, the depth and weight of each pupa were evaluated. Statistical tests were done to verify the relation between weight, depth and distance for pupation. From the total an average of 976 larvae released (488 for each species were collected considering both experiments 456 C. megacephala pupae and 488 of C. albiceps. This demonstrates that C. albiceps probably preyed on 32 C. megacephala larvae during post-feeding dispersion. The study of this dispersion process can be used to estimate the postmortem interval (PMI of human cadavers in legal medicine.As moscas- varejeiras utilizam-se de substratos discretos e efêmeros para alimentar suas larvas.

    After going unreported in the northwestern Atlantic Ocean for 18 years (1988 to 2006), the Asian tiger shrimp, Penaeus monodon, has recently reappeared in the South Atlantic Bight and, for the first time ever, in the Gulf of Mexico. Potential vectors and sources of this recent invader include: 1) discharged ballast water from its native range in Asia or other areas where it has become established; 2) transport of larvae from established non-native populations in the Caribbean or South America via ocean currents; or 3) escape and subsequent migration from active aquaculture facilities in the western Atlantic. This paper documents recent collections of P. monodon from the South Atlantic Bight and the Gulf of Mexico, reporting demographic and preliminary phylogenetic information for specimens collected between North Carolina and Texas from 2006 through 2012. The increased number of reports in 2011 and 2012, ranging from 102 mm to 298 mm total length, indicates that an adult population is present in densities sufficient for breeding, which is indicative of incipient establishment. Based on these reports of P. monodon, its successful invasion elsewhere, and its life history, we believe that this species will become common in the South Atlantic Bight and Gulf of Mexico in less than 10 years. Penaeus monodon is an aggressive predator in its native range and, if established, may prey on native shrimps, crabs, and bivalves. The impacts of an established P. monodon population are potentially widespread (e.g., alterations in local commercial fisheries, direct and indirect pressures on native shrimp, crab and bivalve populations, and subsequent impacts on the populations of other predators of those organisms) and should be considered by resource managers. The impacts of P. monodon on native fauna and the source(s) or vector(s) of the invasion, however, remain unknown at this time.

    International Nuclear Information System (INIS)

    Naked pupae of sweet potato weevil were exposed to gamma rays two or three days before an adult eclosion. The irradiation reduced an adult longevity by half, and atrophied adult testes and ovarioles. Oviducts were swelled and changed in color from milk-white to brown. As irradiated males mated with non-irradiated females and vice versa, most of females had sperm in their spermathecae except insects irradiated at 100 Gy. A doses of 70 Gy was required to prevent a reproduction of adults from irradiated pupae

    The aphid species Sitobion avenae and Rhopalosiphum padi are the most important pests in wheat growing regions of many countries. In this study, we investigated the sublethal effects of imidacloprid on fecundity, longevity, and enzyme activity in both aphid species by comparing 3-h exposure for one or three generations. Our results indicated that 3-h exposure to sublethal doses of imidacloprid for one generation had no discernible effect on the survival, fecundity, longevity, or enzyme activity levels of aphids. However, when pulse exposures to imidacloprid were sustained over three generations, both fecundity and longevity were significantly decreased in both S. avenae and R. padi. Interestingly, the fecundity of R. padi had almost recovered by the F5 generation, but its longevity was still deleteriously affected. These results indicated that R. padi laid eggs in shorter time lags and has a more fast resilience. The change in reproduction behavior may be a phenomenon of R. padi to compensate its early death. If this is stable for the next generation, it means that the next generation is more competitive than unexposed populations, which could be the reason underlying population outbreaks that occur after longer-term exposure to an insecticide. This laboratory-based study highlights the sublethal effects of imidacloprid on the longevity and fecundity of descendants and provides an empirical basis from which to consider management decisions for chemical control in the field.

    A flutuação populacional de Euphoria lurida foi estudada em pomar cítrico misto, abandonado e formado pelas variedades de laranjas baianinha e natal, tangerinas-cravo e rio, tangor-sabará e limão-cravo. Os adultos foram coletados através de armadilhas plásticas iscadas com melaço de cana a 20 %. As coletas foram realizadas quinzenalmente, quando também se procedia à troca da isca. As amostragens ocorreram no período de janeiro/84 a dezembro/86. Foram coletados 716 adultos no período e verificada a ocorrência da espécie durante todos os meses do ano. As maiores médias de coletas foram obtidas nos meses de janeiro, fevereiro e dezembro. O maior pico populacional foi observado no mês de janeiro do terceiro ano. Foram coletados 21,4%, 28,8% e 49,8% dos adultos no primeiro, segundo e terceiro anos de amostragens, respectivamente. A grande disponibilidade de alimento representada pelo alto número de frutos abandonados no solo foi a principal causa do aumento populacional da espécie no último ano de coletas. Estes resultados evidenciam que pomares abandonados, principalmente aqueles com grande quantidade de frutos deixados no solo, propiciam condições favoráveis ao rápido aumento populacional da espécie, que poderá migrar para pomares cítricos produtivos e causar sérios prejuízos atacando as flores e provocando a queda dos frutos em formação.

    The cashew stem girdler, Analeptes trifasciata, is a major insect pest of cashew in Nigeria causing economic damage in cashew plantations even at low density. In this study, newly emerged adults of A. trifasciata reared from field-infested cashew stems were collected from the rearing cages, sexed, and dissected to reveal the internal structures of the insects. The gut was excised and separated into the foregut, midgut, and hindgut. The dissected gut compartments were blotted dry by sandwiching in sterile Whatman No. 1 (150 mm) filter paper for a minute. The inoculated gut parts showed the presence of eight fungi flora, namely, Aspergillus repens, Trichoderma spp., Fusarium verticillioides, Lasiodiplodia theobromae, yeast, Aspergillus niger, Fusarium spp., and Rhizopus stolonifer. The frequencies of occurrence of bacteria in the gut compartments of A. trifasciata were Enterobacter spp.: 83.33%; Escherichia coli and Streptococcus spp.: 55.56% each; Staphylococcus spp.: 44.44%; Klebsiella pneumonia: 50% and Salmonella shigella: 11.11%, while each of Serratia marceascea, Pseudomonas spp., and Micrococcus lutea had 5.56% occurrence. The occurrence of mycoflora and microbiota species varied in the gut compartments of A. trifasciata, indicating the role of these microorganisms in metabolic and other bioprocesses of A. trifasciata during digestion and synthesis of complex food substances from the cashew stem substrate. This study would provide basic information for enzymatic studies of A. trifasciata with a view to developing an integrated pest management (IPM) protocol for managing the pest in cashew plantations.

    Full Text Available Hypopharyngeal glands of honeybee are age-dependent structures that change with the size of acini and are correlated with various social behaviors. The histochemical structure of Apis cerana and A. mellifera worker hypopharyngeal glands in four different developmental stages wes stained with ninhydrin Schiff's and periodic acid Schiff's reagents (PAS for localization of proteins and carbohydrates, respectively, and examined with light microscopy. Nurse bees of both honeybee species had significantly larger glands as compared to guards and forgers, but there were no statistically significant differences between these two species after accounting for caste. Gland protein concentration increased progressively in nurse bees, and this was correlated with the appearance of enriched protein granules in the cytoplasm. In addition, the hypopharyngeal gland protein concentration of A. mellifera was higher than that of A. cerana even though gland size was not significantly different between species. However, gland size was shown to have decreased progressively in foragers and guards.

    Lymphoid cell culture from penaeid shrimps has gained much acceptance as an in vitro platform to facilitate research on the development of prophylaxis, and therapeutic strategies against viruses and for cell line development. However, lymphoid cells can be used as platform for in vitro research, only if they are in metabolically and mitotically active state in vitro with unaltered cell surface receptors. Through this study, we addressed the response of lymphoid cells to a new microenvironment at cellular and molecular levels; including the study of mitotic events, DNA synthesis, expression profile of cell cycle genes, cytoskeleton organization, metabolic activity and viral susceptibility. The S-phase entry and synthesis of new DNA was recorded by immunoflourescent technique. Cdc2, CycA, CycB, EF-1α and BUB3 genes involved in cell cycle were studied in both the cells and tissue, of which EF-1α showed an elevated expression in cells in vitro (∼ 19.7%). Cytoskeleton network of the cell was examined by studying the organization of actin filaments. As the markers for metabolic status, mitochondrial dehydrogenase, protein synthesis and glucose assimilation by the cells were also assessed. Viral susceptibility of the cell was determined using WSSV to confirm the preservation of cellular receptors. This study envisages to strengthen the shrimp cell line research and to bring forth lymphoid cell culture system as a 'model' in vitro system for shrimp and crustaceans altogether.

    Cristina Marques Lisbôa Lopes

    1998-05-01

    Full Text Available The parasitic specificity of larval, nymph and adult Amblyomma cajennense on six different host species: Oryctolagus cuniculus, Rattus norvegicus, Gallus gallus domesticus, Anas platyrhynchus, Coturnix coturnix and Streptopelia decorata is described. In terms of the numbers of larvae and nymphs recovered, O. cuniculus was the best host species. The modal day for drop-off of larvae and nymphs was day three for the mammal hosts, but variable in the birds. We conclude that adult A. cajennense have a strong degree of specificity due to the fact that the tick failed to complete its life cycle on any of the evaluated hosts. The immature stages, on the other hand, showed a low level of specificity, most especially in the larval stage, indicating the existence of secondary hosts which probably serve as dispersers in the wild. The results also indicated a variable drop-off rhythm for larvae and nymphs in two periods, diurnal (6-18 hr and nocturnal (18-6 hr, which differed depending upon the host.

    Full Text Available Abstract Trypoxylon is a genus of solitary crabronid wasps whose population genetics is poorly known. The purpose of the present study was to investigate the genetic variation and differentiation among five populations of Trypoxylon albitarse, a species widely distributed throughout the Neotropics, with records from Panama to northern Argentina. Eight species-specific microsatellite loci were used for genotyping 96 adult wasps (one female per nest sampled at five sites in Brazil. The analysis of allelic richness and private alleles indicated high genetic diversity in the populations sampled. Pairwise comparisons using the Fst and Dest indices revealed significant differentiation for all, but one pair of populations. Fst, Dest, AMOVA and assignment test values pointed to inter-population differentiation. Additionally, the analysis of population structure using Bayesian and PCA methods characterized two alternative genetic groups. The Mantel test indicated no correlation between genetic and geographic distances. Despite evidence of considerable dispersal capacity for T. albitarse, the data indicate low to moderate population structuring in this species.

    Skin lymphomas are now divided into ''T'' or thymic cell lymphomas (mycosis fungoides being the principal type) and ''B'' cell lymphomas after the bursa of Fabricius. The ''T'' cell lymphomas all are identified by the thymic or cerebriform cell. Those lymphomas of the skin which do not contain these characteristic cells are derived from the bursa cells and are termed ''B'' cell lymphomas. A large percentage of these non ''T'' cell lymphomas have been histologically diagnosed as lymphocytic lymphoma of the skin (1). The authors had an opportunity to scan a patient with histologically proven lymphocytic lymphoma of the skin with Ga-67 and obtained on excellent correlation between gallium accumulation in the skin lesions and histologic confirmation of lymphocytic lymphoma.

    This study describes the prevalence, distribution, pathology and pathogenesis of lumbar interspinous bursitis (described as a clinical syndrome by Baastrup in 1933). It is based on an anatomic study of 152 lumbar spines derived from routine and random postmortem material, together with selected specimens from autopsies on patients with various rheumatic diseases. From a statistical study of 50 randomly chosen spines, bursae are found when the interspinous distance is small compared with the total height of the lumbar spine ('bursal index'): nearly all bursal spaces show some sign of inflammation and a few show severe bony erosion. Crystal deposits therein are also described. PMID:7178764

    The sugarcane borer Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae) is an important pest in Brazilian sugarcane crops. Currently, biological control is the most frequently used method for controlling D saccharalis. However, in several locations, the parasitoid Cotesia flavipes (Cameron) (Hymenoptera: Braconidae) has not been effective for controlling this pest, and it has been recorded infestation intensity above 25%. In this context, the Sterile Insect Technique could be an additional control method in Integrated Pest Management, because it is compatible with other control methods. The use of insecticides that interferes in hormone homeostasis involved in the ecdyse's process with exogenous hormone sources or synthetic analogues (agonists or antagonists) can result in the interruption of the reproductive process or abnormal development of the insect?s embryo. Then, the objective of this study was to evaluate the insecticides that regulates the insect growth on the D. saccharalis reproduction. The insecticides tested were: chlorfluazuron (1,0 and 1,5 g a.i./L), diflubenzuron (3,75; 5,0 and 7,5 g a.i./L), flufenoxuron (1,0 g a.i./L), lufenuron (0,75; 1,0 and 2,0 g a.i./L), novaluron (0,5 and 1,0 g a.i./L) pyriproxyfen (1,0; 1,5; 1,8 and 2,0 g a.i./L) and teflubenzuron (1,5; 3,0 and 6,0 g a.i./L). Each insecticide was provided to 1-day moths on soaked cotton with a sugar solution at 10% as a bait. All treatments, except to of the lowest concentration of lufenuron (0,75 g a.i./L) decreased the egg production in relation to the control. Flufenoxuron (1,00 g g a.i./L) and chlorfluazuron (1,50 g a.i./L) decreased the lifespan of both sexes treated by ingestion. Lufenuron (2,0 g a.i./L), novaluron (1,0 g a.i./L) and teflubenzuron (3,0 g a.i./L) decreased the male's lifespan. The most effective treatments for sterilization were pyriproxyfen (1,8 g a.i./L and 2,0 g a.i./L) and lufenuron (2,0 g a.i./L), witch showed efficiencies greater or close to

    Full Text Available Lipoma arborescens (LA is a rare benign lesion of unknown etiology. It is characterized histologically by villous proliferation of the synovial membrane and diffuse replacement of the subsynovial tissue by mature fat cells. This condition affects the knee joint most commonly. Cases involving other locations including glenohumeral joint, [1] hip, [2] elbow, [3] hand [4] and ankle [5] have been rarely described. Involvement of the subdeltoid bursa has also been reported, but to date no case has described LA with osseous/chondroid differentiation of this bursa. Another significant finding in our case was the coexistence of LA with intermuscular lipoma, SLAP lesion and labral cyst.

    Full Text Available Background; Children whose verbal communications are not fully developed are the ones at risk for burn injuries. Causes of burn injuries vary among different age groups and scald injuries are the common cause of burn injuries among children. The majority of burns result from contact with thermal agents such as flame, hot surfaces, or hot liquids.Aim: The aim of this study was to determine etiologic factors of the burn injured children Methods: Data were collected for burn injured children treated in Uludag University Medical Hospital Burn Unit between January 2001 – December 2008. Patients’ demographic variables, etiology of burn injury, TBSA(total body surface area, degree of the burn injury, duration of hospitalization was detected from medical records of the hospitalized patients.Results: The mean age of the children was 2.5±1.5 (median=2. Although 4.6 % of burned patients were under one year of age, most of the children (67.8% were between 1-3 years. All of the patients were burned as a result of accident and house environment was the place where the burn incident occurred. Burn injuries occurredmostly during summer (29.9% and spring (28.7%. Scald injuries (75.3% were mostly seen burn injury types all among other burn injuries.Conclusions: Lack of supervision and observation are usually the most common causes of burn injuries in children. Statistical differences were found among age groups according to their burn etiology (p<0.05. An effect of TBSA on patient survival was statistically significant (p<0.000 and also statistically significant results were seen among age groups according to their TBSA’s (p<0.005.

    The experiment was conducted with the objective of studies on effects of zinc toxicity on lymphoid organs by the methods of experimental pathology and flow cytometry (FCM). 200one-day-old Avian broilers were divided into four groups randomly, and fed on diets as follows: controls (Zn 100mg kg-1)and zinc toxic (Zn 1 500mg kg-1, zinc toxic group Ⅰ; Zn 2 000 mg kg-1, zinc toxic group Ⅱ; Zn 2 500 mg kg-1, zinc toxic group Ⅲ) for seven weeks. The weight and growth index of the thymus, spleen and bursa of Fabricius were reduced in both zinc toxic group Ⅱ and zinc toxic group Ⅲ when compared with those of control group. The G0/G1 phase of the cell cycles of the lymphoid organs was higher, and S, G2+M phases lower in zinc toxic groups Ⅱ and Ⅲ than in control group. Lymphocytes were depleted and degenerate in the lymphoid organs. The reticular cells of the bursa of Fabricius proliferated and the reticular cells of the thymus were also degenerate and necrotic,particularly in zinc toxic groups Ⅱ and Ⅲ. The results demonstrated that more than 1 500 mg kg-1 impaired the progression of lymphocytes from the G0/G1 phase to S phase obviously, inhibited the development of lymphoid organs and caused marked pathological changes in the lymphoid organs. Potential mechanisms underlying these observations are also discussed.

    Full Text Available An outbreak of Marek’s disease was reported to occur in broiler chicken in Districts of Tasikmalaya and Ciamis. A total number of 58 tissues samples of broiler chicken were collected from 7 flocks of commercial broiler chicken farms in both Districts. The disease affected broiler chicken aged 17 to 24 days. Those chickens had been vaccinated to Newcastle Disease (ND and at age of 10 days had been vaccinated to Gumboro using blended bursa of fabricius. Tissue samples were fixed in 10% of buffered neutral formalin (BNF prior to haematoxilin and eosin (H and E stain using standard procedures. Histopathological features show that out of 58 samples, 32 (55.2% were infected by Marek’s Disease (19.0% were infected by Marek’s Disease, 20.1% were infected by Marek’s Disease and Gumboro, 16.1% Marek’s Disease and other infections, whereas 44.8% were infected by Gumboro alone or accompanied by other infections, ND and Colibasillosis. The study reveals that Marek’s Disease infection in broiler chicken tends to be mild i.e. infiltration of neoplastic cells (lymphoid, pleomorphic in proventriculus, intestine, spleen, livers and bursa of fabricius. In addition to this, there were mild non-supurative inflammation in heart, lung, peripheral nerve and brain, as well as a severe demyelination in brain. It is concluded that the histopthological features confirm the diagnosis of Marek’s Disease.

Walp. seeds was assessed under laboratory conditions in Akure, Nigeria. In the tests, 20 g of infested cowpea seeds were suspended in a piece of muslin cloth, over an amount of crushed bulb in a container with a tightly fitted lid. Adult emergence was completely prevented from freshly laid eggs of C. maculatus on cowpea seeds that was fumigated with 6.0 g or more of crushed bulbs of A. sativum. Such fumigated seeds were not holed at all. Other amounts of A. sativum tested (1.0, 2.0, 3.0, 4.0 and 5.0 g significantly reduced C. maculatus adult emergence from fumigated eggs and seed holing in comparison with the control. Crushed A. sativum was ineffective in preventing adult emergence from fumigated C. maculatus larvae in seeds. The fumigant effect of crushed A. cepa did not kill all C. maculatus eggs. An amount of 7.0 g significantly reduced C. maculatus adult emergence from fumigated eggs and seed holing in comparison with the control. There is good prospect in using crushed bulbs of A. sativum> as fumigant in C. maculatus control in stored cowpea seeds.Se evaluó la toxicidad fumigante de bulbos frescos trozados de Allium sativum L. y A. cepa L. sobre Callosobruchus maculatus (Fabricius, una importante plaga de semilla almacenada de caupí Vigna unguiculata (L.

    Reassortment among genome segments of infectious bursal disease virus (IBDV) field isolates was reported frequently worldwide, however the pathogenicity of the reassortant field IBDV is poorly understood. In this paper, a pathogenicity study on four representative IBDV field strains isolated from Southern China between 2005 and 2011 was conducted. Twenty-eight-day-old Three-Yellow chickens were divided into four groups and were inoculated intraocularly with one of the four field IBDV strains, namely NN1172, NN1005, GD10111 and JS7, respectively. The mortality and relative weight of bursa and thymus were subsequently determined in the acute phase of infection. In addition, B cells, T cells (CD4(+) and CD8(+)) and virus were quantified in the bursa of Fabricius and thymus, respectively, by flow cytometry and real-time reverse transcription-polymerase chain reaction. The results showed that isolate NN1172, of which parts of segment A and B encoding the hypervariable (v) region of viral protein (VP2) and VP1, respectively, derived from vvIBDV strains, showed the most severe pathogenicity, and caused the most severe bursal B cell depletion as well as CD4(+) and CD8(+) T cell infiltration in the bursa of Fabricius. However, the virus induced the strongest decrease in CD4(+) and CD8(+) T cells in the thymus and exhibited the most efficient viral replication in the target organs. Isolate NN1005, whose vVP2 derived from vvIBDV and VP1 from unidentified origin, exhibited relatively lower pathogenicity compared to NN1172. The other two isolates, JS7 and GD10111, of which the vVP2 derived from vvIBDV and intermediate IBDV, and VP1 from 002-73 and attenuated IBDV, respectively, showed the lowest level of virulence. Our results suggest that various IBDV field isolates with different natural segment reassortments exhibit differential pathogenicity after infection of commercial Three-Yellow chickens.

    A first comprehensive textbook on burns treatment was written in 1607 by Fabry of Hilden (Fabricius Hildanus). This monograph describes cause, diagnosis, treatment, and complications of burn injuries. Besides a variety of topical ointments with promising herbal ingredients like onion and camphor, surgical procedures like necrectomies, escharotomies and syndactely treatment are described for the first time ever. Scar management including splinting devices is another interesting topic. Some of the therapeutic procedures are still valid today. Thus this renaissance piece of medical writing belongs to the pedigree of surgery. PMID:20017089

    Full Text Available The biology of immature stages of S.sphegea and different techniques for their laboratory rearing has been studied during the past five years (1972-77. This fly is one of the 18 Iranian species of snail-killing flies which is dominant in the focus area of schistosomiasis (Khuzestan Province in the south-west of Iran. The following procedures improved appreciably our laboratory rearin-technics and greatly reduced larval mortality: 1- Large number of fresh aquatic snails required for the progress of this study has been obtained at the entrances of the traditional under ground water canals (Ghanat in Teheran. These canals are almost permanent sources of snails because their water temperatures are rather constant through out the year and the water is by far protected from the surface pollution. In other cases, fresh snail was brought from distant swamp and rice fields. Attempts to maintain and to rear live aquatic snails, in large container equipped with aeration pump were not successful due to infection with coli form bacteria. Although the infected snails did not show any biological ill symptoms, could cause heavy mortality among larvae of flies. 2- Fly larvae were reared in plastic container of 28×32 cm. containing 7 to 8 liters of water (7 to 8 cm.depth. Eight to 12 laboratory vials filled with water were placed vertically in several rows in each container to secure uniform distribution of both snails and fly larvae. Fresh and dried leaves of lettuce were used to feed the snails. 3- Dead snails and their shells were picked out by forceps and half of the volume of water of all containers was drained from the bottom by siphoning every two days. 4- The surface pollution of water in the containers, which caused high mortality in different stages of larval development, was removed every four to five days by strips of blotting paper. The oily missed pollution on the water-surface was mostly due to dead snails, rotten leaves of lettuce and to a lesser

    Stored products such as grains, flours, dry fruits and spices are normally infested by pests as beetles (Lasioderma serricorne), mites and moths, depreciating the product visually and promoting its deterioration. To improve the quality of spices, medicinal plants, seasoning and others foodstuffs there is a need for adequate methods of handling, correct identification of the species, adequate collection, pre and post-treatment procedures and adequate storage. The objective of this work was to determine the dose of gamma radiation for the disinfestations of medicinal and aromatic plants dehydrated infested by L. serricone. The plants used in this study were Cymbopogon citratus stapf (lemon grass) and Ocimun basillicum L. (basil) in this dehydrated form. The experiment was carried out in the Arthropods Laboratory of the Instituto Biologico/SP, during the months of January and May 2006, and the irradiations were carried out in the Instituto de Pesquisas Energeticas e Nucleares-IPEN/CNEN/SP, using an experimental Cobalt 60 irradiator, model Gammacell 220. Each treatment consisted of 5 parcels containing 10g of dehydrated products infested with 20 last instar larvae of L. serricorne, conditioned in plastic 10x10 cm containers with small punctures in the cover to allow internal aeration. The substratum previously infested was kept for 1 day in a acclimatized room at 27 {+-} 2 deg C, after this period the substratum was submitted to increasing doses of gamma radiation: 0; 0,5; 0,75; 1,0; 1,25; 1,50; 1,75; 2,0; 2,25; 2,50 e 2,75 kGy. After irradiation, the samples were kept in a acclimatized room at 27 {+-} 2 deg C of temperature and relative humidity of 70 {+-} 5 % and after a 45 days period the number of adults insects emerged was evaluated. The lethal dose of gamma radiation for L. serrricorne last instar larvae on Cymbopogon citratus stapf and Ocimun basillicum L. was 1,75 kGy. (author)

    Ticks are classified into three families: Argasidae, Ixodidae, and Nutalliellidae. The taxonomy and phylogeny within Ixodidae are still discussed by the specialists, thus requiring further studies. Amblyomma cajennese and Amblyomma aureolatum (Brazil) belong to two species complexes known as "cajennese" and "ovale", respectively, and are directly related to the transmission of the Brazilian spotted fever. This confirms the medical and veterinary significance of these species, as well as the need for further morphological studies that will bring a better understanding of their taxonomy, phylogeny, and control. In this context, the present study aimed to characterize the morphology of the male reproductive system of A. cajennese and A. aureolatum when unfed and after 4 days of feeding, thereby seeking to: (a) distinguish the two species or "complexes", and (b) study an internal system which has the potential to be targeted by acaricides. Therefore, males from both species (unfed and after 4 days of feeding) were cold-anesthetized, dissected, and had their reproductive systems removed for histological analysis. The results showed that the morphology of the male reproductive system is generally similar between both species, like in other Ixodidae ticks, exhibiting a multilobed accessory gland complex related to seminal fluid secretion, a pair of vasa deferentia and a pair of testes housing germ cells (spermatocytes) in different stages. The main differences were found in the development of the accessory gland complex cells and germ cells, showing that the maturation of the male reproductive system starts later in A. aureolatum, when compared to A. cajennese. However, during the blood meal, A. aureolatum development is increased, thus making germ cell maturation and gland complex activity higher than in A. cajennese. This study shows the differences in the development of the male reproductive systems of both species, while providing information that can assist in the

    This study investigated the potential effects of flunitrazepam (known as "date rape drug") on the developmental cycle of Chrysomya megacephala, an important forensic species, and their possible implications for the calculation of the PMI. A 1050 C. megacephala eggs were divided into five groups with seven replications each. The eggs were placed on artificial diet prepared with four drug concentrations of flunitrazepam (4, 8, 16, and 32 ng/g), besides the control group (prepared with water). Were evaluated the potential effects on development time, weight gain, and mortality during the cycles. The drug had no significant effect on development time or mortality although it did affect the weight of the pupae and adults (Kruskal-Wallis, p < 0.05). The result can be deduced that the determination of the postmortem interval is not affected. PMID:27143233

    Considering that crimes against animals such as illegal killing and cruelty have been alarmingly increasing and since burning is one of the common ways for disposing cadavers, ability to estimate minimum postmortem interval (PMI) using entomological data merits consideration. Chrysomya megacephala and Chrysomya rufifacies are common necrophagous species recovered from cadavers in many countries including Malaysia. Specific studies focusing on the oviposition and developmental patterns of both species on cadavers manifesting different levels of burn as described by the Crow-Glassman Scale (CGS) remain scarce. In four replicates, rabbit carcasses were burned to CGS levels #1, #2 and #3 by varying the amount of petrol used and duration of burning. Oviposition by C. megacephala and C. rufifacies was delayed by one day in the case of carcasses burned to the CGS level #3 (p0.05) in the duration of development were found between control and burned carcasses. These findings deserve consideration while estimating minimum PMI since burning as a mean for disposing animal and human cadavers is gaining popularity. PMID:26779962

    The fumigant toxicity of Xylopia parviflora (A. Rich.) Benth (Annonaceae) root bark's essential oil (EO) against cowpea seed bruchid, Callosobruchus maculatus, was investigated in the laboratory. Dose had significant (P < 0.0001) effect on mortality at 6 hours after treatment (HAT) at a concentration of 6.25 μL/mL air which exerted 81.70% mortality, while there was no mortality in all other lower doses. At 12 HAT, 75.05% and 90.00% mortality were observed at doses of 3.15 and 6.25 μL/mL air, respectively. It was significantly (P < 0.05) higher than the mortality (50.58%) observed when 0.78 μL/mL air was applied. The lethal time for 50% of assayed adults (LT50) obtained when the bruchid was exposed to X. parviflora EO at a dose of 6.25 μL/mL air (2.71 h) was significantly lower than LT50 obtained at exposure of bruchid to other lower doses of 0.78-3.15 μL/mL air.

    Partial sequences of the mitochondrial COI gene of forty eight European and two Turkish population samples of Myzus cerasi from different winter hosts (Prunus spp.) were subjected to phylogenetic analyses. The analysed M. cerasi samples emerged as paraphyletic relative to a Myzus borealis sample used as an out-group, and formed two major clades in neighbor joining, maximum parsimony, maximum likelihood and Bayesian inference trees, corresponding to subspecies living specifically on Prunus avium and P. cerasus. Multivariate discriminant analysis (method of canonical variates) was applied to find out if morphological variation of samples correlated with mitochondrial COI and host plant information. Mean scores on the first two canonical variables clustered samples fully in accordance with their COI haplotypes and host plants confirming the existence of two morphologically similar winter host - specific subspecies of M. cerasi in Europe. No single morphological character enabled satisfactory discrimination between apterous viviparous females of the two subspecies. A three-character linear discriminant function enabled 92.37% correct identification of apterous viviparous females of M. cerasi cerasi (n = 118) and 93.64% of M. cerasi pruniavium (n = 110). A key for the morphological identification of the two subspecies is presented and their taxonomic status is discussed. PMID:24715766

    An 11-day trial was conducted to investigate the osmoregulatory capacity (OC) and regulation of K(+), Na(+), Ca(2+) and Mg(2+) of Penaeus monodon juveniles when exposed to K(+) deficient inland saline water (ISW) of four different salinities (5, 15, 25 and 35 ppt). The survival of juveniles showed a positive linear relationship (R(2) ranging from 0.72 to 0.98) with salinity. At the end of the trial, juveniles were able to survive only in 5 ppt of ISW and showed no changes in OC when transferred from ocean water (OW) to ISW. Further, the OC of juveniles in 5 ppt of ISW was significantly different (Pjuveniles exposed to 15, 25 and 35 ppt and exhibited strong serum K(+), Na(+), Ca(2+) and Mg(2+) regulation monitored over 16 h. In contrast, at 35 ppt, significant decrease (Pjuveniles, which in turn causes decrease in the OC of the juveniles. The results of this study suggest that K(+) deficiency in ISW has a negative effect on survival, OC and the ability of P. monodon juveniles to regulate serum Na(+), K(+), Ca(2+) and Mg(2+) concentrations. These effects are compounded as salinity increases.

    Full Text Available Neuropeptides play essential roles in a variety of physiological responses that contribute to the development and reproduction of insects. Both the diapause hormone (DH and pheromone biosynthesis activating neuropeptide (PBAN belong to the PBAN/pyrokinin neuropeptide family, which has a conserved pentapeptide motif FXPRL at the C-terminus. We identified the full-length cDNA encoding DH-PBAN in Maruca vitrata, a major lepidopteran pest of leguminous crops. The open reading frame of Marvi-DH-PBAN is 591 bp in length, encoding 197 amino acids, from which five putative neuropeptides [DH, PBAN, α-subesophageal ganglion neuropeptide (SGNP, β-SGNP and γ-SGNP] are derived. Marvi-DH-PBAN was highly similar (83% to DH-PBAN of Omphisa fuscidentalis (Lepidoptera: Crambidae, but possesses a unique C-terminal FNPRL motif, where asparagine has replaced a serine residue present in other lepidopteran PBAN peptides. The genomic DNA sequence of Marvi-DH-PBAN is 6,231 bp in size and is composed of six exons. Phylogenetic analysis has revealed that the Marvi-DH-PBAN protein sequence is closest to its homolog in Crambidae, but distant from Diptera, Coleoptera and Hymenoptera DH-PBAN, which agrees with the current taxonomy. DH-PBAN transcripts were present in the head and thoracic complex, but absent in the abdomen of M. vitrata. Real-time quantitative PCR assays have demonstrated a relatively higher expression of Marvi-DH-PBAN mRNA in the latter half of the pupal stages and in adults. These findings represent a significant step forward in our understanding of the DH-PBAN gene architecture and phylogeny, and raise the possibility of using Marvi-DH-PBAN to manage M. vitrata populations through molecular techniques.

    Iridoid glycosides are secondary plant compounds that have deterrent, growth reducing or even toxic effects on non-adapted herbivorous insects. To investigate the effects of iridoid glycoside containing plants on the digestive metabolism of a generalist herbivore, larvae of Spilosoma virginica (Lepidoptera: Arctiidae) were reared on three plant species that differ in their secondary plant chemistry: Taraxacum officinale (no iridoid glycosides), Plantago major (low iridoid glycoside content), and P. lanceolata (high iridoid glycoside content). Midguts of fifth instar larvae were assayed for the activity and kinetic properties of β-glucosidase using different substrates. Compared to the larvae on T. officinale, the β-glucosidase activity of larvae feeding on P. lanceolata was significantly lower measured with 4-nitrophenyl-β-d-glucopyranoside. Using the iridoid glycoside aucubin as a substrate, we did not find differences in the β-glucosidase activity of the larvae reared on the three plants. Heat inactivation experiments revealed the existence of a heat-labile and a more heat-stable β-glucosidase with similar Michaelis constants for 4-nitrophenyl-β-d-glucopyranoside. We discuss possible mechanisms leading to the observed decrease of β-glucosidase activity for larvae reared on P. lanceolata and its relevance for generalist herbivores in adapting to iridoid glycoside containing plant species and their use as potential host plants.

Qualitative and quantitative analyses alcoholic extract of Andrographis paniculata using TLC, revealed that the extracts contain three important compounds in total lactone of 30.49% w/w. There are andrographolide,14-deoxy-11-12-didehydroandrographolide and neoandrographolide. TLC-chromatogram of Clinacanthus nutans extract after reacted with anisaldehyde/sulfuric acid showed a 9 key compounds, while preliminary neutralization test of the compounds revealed that there were active compounds against HSV-1 virus. In vitro efficacy test revealed that Curcuma longa and Andrographis paniculata extracts at 250 and 1,500 mg/L could eradicate 15 isolates of Vibrio spp. which were isolated from infected shrimps. Effects of medicinal plant extracts incorporated into the diet on shrimp immune responses were investigated. Shrimp fed diet containing Clinacanthus nutans extract at 20 mg/kg of diet had good growth, FCR and immune responses. The shrimp that were fed diet containing Curcuma longa extracts at 25 mg/kg of diet for 7-14 days showed high resistance to Vibrio harveyi. Likewise, the shrimp fed Andrographis paniculata extract at 25 mg/ kg of diet for 14 days had a higher resistance to WSSV. Incorporating the medicinal extracts at higher levels resulted in reduction in diet palatability which consequently had an effect on a decrease in growth, immune responses and resistance to bacterial and WSSV infection.

    Full Text Available Two feeding trial were conducted to determine the effects of various sources of carotenoid on growth performance, disease resistance, blood parameters, stress tolerance and pigmentation in juvenile black tiger shrimp (Penaeus monodon. Trial I was performed in small shrimp (1 g average body weight. The shrimp were fed with control diet without carotenoid (diet 1 while diets 2 to 6 contained 50 mg/kg astaxanthin (Lucanthin Pink®, 125 mg/kg β-carotene (Lucarotin®, 200 mg/kg β-carotene (Lucarotin®, 125 mg/kg Betatene® extracted from Dunaliella and 3% dried Spirulina respectively. There was an improvement in color in all groups of shrimp fed caroteniod supplemented diets, but no significant differences in weight gain or survival among the shrimps fed each test diet (p>0.05. Resistance to white spot syndrome virus (WSSV infection and stress tolerance (salinity stress, were not significantly different among treatments. Trial II was performed in juvenile shrimp (10 g average body weight fed test diets containing 100 ppm astaxanthin (Lucanthin pink®, 125 mg/kg β-carotene (Lucarotin®, 250 mg/kg β-carotene (Lucarotin®, 250 mg/kg Betatene® and 3% dried Spirulina compared with those fed control diet without carotenoid. At the end of 6 weeks feeding period, shrimp fed control diet as well as astaxanthin and dried Spirulina supplemented diets had higher levels of total hemocyte counts than those of all β-carotene supplemented diets feeding group. However, phenoloxidase activity and clearance of pathogenic vibrio from the hemolymphwere not significantly different among the treatments (p>0.05. Astaxanthin levels were highest in the shrimp fed all carotenoid-supplemented diets. In conclusion, a natural carotenoid i.e. dried Spirulina and carotenoid extracted from Dunaliella which have a lower production cost than analytical carotenoid showed beneficial effects on shrimp feed supplement.

    1998-01-01

    Isolates of Marek's disease virus (MDV) representing three pathotypes of differing virulence were compared for relative immunosuppressive properties in genetically susceptible P2a-strain and genetically resistant N2a-strain chickens. Criteria of immunosuppression were 1) persistence of early cytolytic infection (i.e., a delay or failure to enter latency) in lymphoid organs, 2) atrophy of the bursa of Fabricius and thymus as measured by organ weight proportional to body weight at 8 and 14 days postinfection (DPI), and 3) histopathologic evidence of necrosis and atrophy in lymphoid organs. No significant differences in infection level were observed among the pathotypes during the early (4-5 DPI) period of infection. However, the extent of persistent cytolytic infection at 7-8 DPI, based on numbers of tissues positive and mean scores in immunofluorescence tests, was greater (P Md5) classified in the intermediate very virulent pathotype (very virulent MDV [vvMDV]) fell between those from the other two pathotypes. Similarly, there was a stepwise effect of viral pathotype in which the vv + MDV isolates caused the most severe damage to lymphoid organs in terms of atrophy (relative organ weights) and histopathologic changes. Organs from chickens infected with vv + MDVs showed little recovery between 8 and 14 DPI. The vMDV isolates caused the least severe damage, and lymphoid organs showed a significant return toward normal by 14 DPI; vvMDV isolates induced intermediate degrees of atrophy and recovery. The same pattern of relationship between virulence pathotype and degree of bursal and thymic atrophy was also observed in genetically resistant N2a chickens. These results suggest that the degree of immunosuppression is linked to virulence and that a simple measure of atrophic changes (relative organ weights) in the bursa of Fabricius and thymus might be useful in determining the pathotype classification of new MDV isolates. The basis for differences in immunosuppressive

    Full Text Available It was intended to reveal the time dependent power generation under different loads for two different solar panels under the conditions of Bursa province in between August 19 and 25, 2014. The testing sets include solar panels, inverter, multimeter, accumulator, regulator, pyranometer, pyrheliometer, temperature sensor, and datalogger. The efficiency of monocrystalline and polycrystalline solar panels was calculated depending on the climatic data’s measurements. As the result of the study, the average performances of monocrystalline and polycrystalline panels are 42.06 and 39.80 Wh, respectively. It was seen that 87.14 W instantaneous power could be obtained from monocrystalline solar panel and that 80.17 W instantaneous power could be obtained from polycrystalline solar panel under maximum total radiation (1001.13 W/m2. Within this frame, it was determined that monocrystalline solar panel is able to operate more efficiently under the conditions of Bursa compared to polycrystalline solar panel. When the multivariate correlations coefficients were examined statistically, a significant relationship in positive direction was detected between total and direct radiation and ambient temperature on energy generation from monocrystalline and polycrystalline panel.

    The safety of feeding transgeniccry1Ab/cry1Ac rice (a geneticaly modiifed (GM) rice variety) to broilers was examined from an immunological perspective. Hatchling Arbor Acres chickens (240) were assigned to two dietary treatments (diets containing GM or non-GM rice) with 12 replicates per group and 10 birds per replicate. Traits were measured on one randomly selected bird from each replicate at d 21 and 42. The 42-d feeding trial revealed thatcry1Ab/cry1Ac rice had no signiifcant effect relative to non-GM rice on body weight and the immune organ indices. No signiifcant pathological lesion in the spleen and bursa of Fabricius was found in the GM rice group. There were no signiifcant differences in serum concentrations of immunoglobulin Y (IgY), IgM, interleukin 4 (IL-4) and IL-6 between the two groups at d 21 or 42, except for IL-6 being higher (P<0.05) in the GM-fed chickens at d 42. There were no differences in the T and B lymphocyte transformation rate and CD4+/CD8+ ratio between the two groups at d 42. Additionaly, there was no signiifcant difference between the two diets in expression of relevant genes viz. the major histocompatibility complex class II beta chain (BLB2), interferon beta 1 (IFNβ), tumour necrosis factor alpha-like (TNFα) and tol-like receptor 4 (TLR4) in the spleen and bursa of Fabricius. Al the data demonstrated that transgeniccry1Ab/cry1Acrice had no adverse effect on these aspects of immune function of broilers during 42-d feeding trial. Transgenic rice was therefore indistinguishable from non-GM rice in terms of short-term feeding in chickens.

    Full Text Available The objective of the present study was to assess the development of broiler chicks during the first week post-hatching when reared at three different environmental temperatures. A total of 480 day-old chicks were placed in three environmentally controlled rooms (20, 25 and 35°C from 1 to 7 days of age. Body weight gain, feed and water intake, as well as liver, gizzard, heart, yolk sac and bursa of Fabricius weights were measured daily. Tibia and femur bones were weighed and their length and width (medial diameter were also obtained. The chicks reared at 20º C had lower weight gain and ingested less food than chicks reared at 25°C and less water than chicks kept at 35°C. Relative weights of the liver, heart, and gizzard were affected by environmental temperature, whereas yolk sac and bursa of Fabricius relative weights were not. The data showed that all bone parameters increased with bird age. Environmental temperature did not affect tibia or femur width, however a significant increase in bone weight and length occurred with increasing environmental temperature. These results indicate that brooding temperature of 20°C during the first seven days post-hatching was stressful decreasing broiler bone development and reducing chicks body weight.O presente trabalho teve como objetivo estudar o efeito de diferentes temperaturas-ambiente durante a primeira semana de vida de pintos de corte sob parâmetros zootécnicos, desenvolvimento visceral e crescimento ósseo.

    In this study, antioxidant and antimicrobial potentials of Usnea intermedia, U. filipendula, and U. fulvoreagens and their stictic and usnic acid contents were investigated. Antioxidant activity and total phenolic contents were evaluated in acetone, ethanol, and methanol extracts of these three species. Antioxidant activity was measured by ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)] method and total phenolic contents were measured by Folin-Ciocalteu method. High-performance liquid chromatography (HPLC) was used for the determination of lichen acids. It can be concluded from stictic and usnic acids contents that the order of solvent efficiency is acetone > ethanol > methanol and acetone > methanol > ethanol, respectively. Broth microdilution method was performed to determine the minimum inhibitory concentration (MIC) of the methanol extracts of three Usnea species. The MIC values of all the extracts ranged from 64 µg/mL to 512 µg/mL for all the bacterial strains that were tested in this study, and all the Fluoro quinolone-resistant Escherichia coli isolates (except for E101) were sensitive to the methanol extracts of the three Usnea species. This paper is the first study to determine the stictic acid content in U. intermedia and U. filipendula. Our findings indicate that these three Usnea species could be used as antioxidant and antimicrobial agents. PMID:27642324

    Trenbolone acetate is a synthetic androgen that is currently used as a growth promoter in many meat-exporting countries. Despite industry laboratories classifying trenbolone as nonteratogenic, data showed that embryonic exposure to this androgenic chemical altered development of the immune system in Japanese quail. Trenbolone is lipophilic, persistent, and released into the environment in manure used as soil fertilizer. This is the first study to date to assess this chemical's immunotoxic effects in an avian species. A one-time injection of trenbolone into yolks was administered to mimic maternal deposition, and subsequent effects on the development and function of the immune system were determined in chicks and adults. Development of the bursa of Fabricius, an organ responsible for development of the humoral arm of the immune system, was disrupted, as indicated by lower masse, and smaller and fewer follicles at day 1 of hatch. Morphological differences in the bursas persisted in adults, although no differences in either two measures of immune function were observed. Total numbers of circulating leukocytes were reduced and heterophil-lymphocyte ratios were elevated in chicks but not adults. This study shows that trenbolone acetate is teratogenic and immunotoxic in Japanese quail, and provides evidence that the quail immune system may be fairly resilient to embryonic endocrine-disrupting chemical-induced alterations following no further exposure posthatch.

    Full Text Available The bursa of Fabricius is critical for B cell development and differentiation in chick embryos. This study describes the production in vitro, from dissociated cell suspensions, of cellular agglomerates with functional similarities to the chicken bursa. Co-cultivation of epithelial and lymphoid cells obtained from embryos at the appropriate developmental stage regularly led to agglomerate formation within 48 hours. These agglomerates resembled bursal tissue in having lymphoid clusters overlaid by well organized epithelium. Whereas lymphocytes within agglomerates were predominantly Bu-1a(+, a majority of those emigrating onto the supporting membrane were Bu-1a(- and IgM(+. Both agglomerates and emigrant cells expressed activation-induced deaminase with levels increasing after 24 hours. Emigrating cells were actively proliferating at a rate in excess of both the starting cell population and the population of cells remaining in agglomerates. The potential usefulness of this system for investigating the response of bursal tissue to avian Newcastle disease virus (strain AF2240 was examined.

    Full Text Available Abstract Background This study aimed at investigating a potential effect caused by coccidia on the immune response to vaccine- and very virulent infectious bursal disase virus (vvIBDV in SPF chickens. Methods Two groups of three weeks old SPF chickens were vaccinated prior to inoculation with coccidia and challenge with virulent IBDV, all within a period of eight days. Two control groups were similarly treated, except that challenge with field virus was omitted in one group while inoculation with coccidia was omitted in the other group. Clinical signs, lesions in the intestines caused by coccidia, lesions in the bursa of Fabricius caused by IBDV, IBDV-antibody titres, and virus detection by reverse transcription polymerase chain reaction (RT-PCR were compared among the groups. Lymphoid tissues and swab samples were analysed by general RT-PCR, and positive results were identified by strain specific duplex (DPX RT-PCR. Results In the tripple-infected groups, vaccine strain IBDV was detected in spleen and thymus tissues, and no field virus was detected in bursa samples, contrary to the double-infected groups. Conclusion The results suggest an enhancing effect on the immune response caused by subclinical coccidiosis and vvIBDV acting in concert.

    The effect of different gama radiation (60Co) doses on Chrysomya megcephala (Fabricius) have been studied under laboratory conditions, in the Entomology Section of Centro de Energia Nuclear na Agricultura (CENA-USP), Piracicaba, SP, Brasil. The insects were collected close to sucking animals brooding areas, identified and reared on artificial diet, being kept in a temperature (26 +- 20C) and humidity (66 +- 9%) controlled room, with 12L:12D photopheriod. A Gammabeam type 650 Cobalt-60 gamma irradiation source was used, with 28, 196x1010 Bq activity at the beginning of the experiment. The pupae were submitted to increasing gamma radiation doses. To determine lethal doses, treatments were carried out at four different ages and to determine the sterilizing doses two-three day pupae were used. It was noted pupae radiosensitivity decreased with age, LD50 varying from 14 - 513 Gy. The sterilizing dose for males was 40 Gy and for females 30 Gy. During the individuals life cycle, it was noted that there was a decrease in life expectancy (exo) of adults when the gamma radiation dose was increased. Treated males were more sensitive than females (Crossed with ''normals''), there occurring a marked reduction in the number of eggs and their viability when the used gamma radiation dose was increased.

    A developed discipline of econophysics that has been introduced is exhibiting the application of mathematical tools that are usually applied to the physical models for the study of financial models. In this study, an analysis of the time series behavior of several blue chip and penny stock companies in Main Market of Bursa Malaysia has been performed. Generally, the basic quantity being used is the relative price changes or is called the stock price returns, contains daily-sampled data from the beginning of 2003 until the end of 2008, containing 1555 trading days recorded. The aim of this paper is to investigate the tail exponent in tails of the distribution for blue chip stocks and penny stocks financial returns in six years period. By using a standard regression method, it is found that the distribution performed double scaling on the log-log plot of the cumulative probability of the normalized returns. Thus we calculate α for a small scale return as well as large scale return. Based on the result obtained, it is found that the power-law behavior for the probability density functions of the stock price absolute returns P(z)˜z-α with values lying inside and outside the Lévy stable regime with values α>2. All the results were discussed in detail.

    Full Text Available ABSTRACT. Chrysomya albiceps (Wiedemann and Hemilucilia segmentaria (Fabricius (Diptera, Calliphoridae used to estimate the postmortem interval in a forensic case in Minas Gerais, Brazil. The corpse of a man was found in a Brazilian highland savanna (cerrado in the state of Minas Gerais. Fly larvae were collected at the crime scene and arrived at the laboratory three days afterwards. From the eight pre-pupae, seven adults of Chrysomya albiceps (Wiedemann, 1819 emerged and, from the two larvae, two adults of Hemilucilia segmentaria (Fabricius, 1805 were obtained. As necrophagous insects use corpses as a feeding resource, their development rate can be used as a tool to estimate the postmortem interval. The post-embryonary development stage of the immature collected on the body was estimated as the difference between the total development time and the time required for them to become adults in the lab. The estimated age of the maggots from both species and the minimum postmortem interval were four days. This is the first time that H. segmentaria is used to estimate the postmortem interval in a forensic case.

    Full Text Available The aim of the thesis was to investigate life cycle, biological and morphological characteristics of pear shoot sawfly (Janus compressus Fabricius, Hymenoptera Cephidae, furthermore to identify natural enemies in order to protect pear from this pest. The trial was conducted in the period of three years: 2010, 2011 and 2012 in pear orchards at five localities. Monitoring of adult sawfly was done by yellow sticky traps. Laboratory research was done at the Faculty of Agriculture, Department of Plant Protection, Section of Entomology and Nematology. In this study, pear shoot sawfly in Eastern Slavonia occurred in the period of four weeks, starting from the third decade of April with the peak population at the beginning of the May. Adults flight is the most intensive during warm and sunny days, when temperatures are above 14°C. Adult sawflies are characterized by elongated body and antennae, usually 7-12 mm long and sexual dimorphism is present. Pest is univoltine. Basic colour of adult sawfly is black. Antennae are moniliform and consist of 20 (male - 22 (female segments. Females have red or dark red colored abdomen, while males have yellow or orange one. Eggs are cylindrically shaped, 0.8-1.0 mm long. Female lays approximately 30 eggs. Embryonic development of pear shoot sawfly eggs lasts from 11 to 14 days. Larvae are 8-10 mm long, white or pale yellow. Larvae molt three times. Pear shoot sawfly larvae were parasitized by insects from Hymenoptera order, from five identified and one unidentified genera. Level of parasitism by genera is as follows: Eurytoma sp. (Hymenoptera: Eurytomidae – 9.83%, Tetrastichus sp. (Hymenoptera: Eulophidae – 2.01%, Eupelmus sp.

    Abstract Nebria brevicollis (Fabricius) is one of the most frequently encountered and widely distributed carabid beetles in Europe. Until recently, the only North American records were based on two single specimens, both from the 1930’s in southeastern Canada. In 2008, this species was found at thirteen different sites in five counties in northwestern Oregon. As of the end of 2010, it has been found in thirty-four different sites in ten Oregon counties, with a north-south range of ~150 km and an east-west range of ~90 km. It was also detected in 2010 in southwestern Washington (Vancouver), just north of Portland and the Columbia River. The ecological amplitude of Nebria brevicollis in Oregon rivals that of the most eurytopic native carabid species, e.g., Pterostichus algidus LeConte and Scaphinotus marginatus (Fischer von Waldheim). It has been found in highly degraded heavy industrial sites, agricultural fields, city parks, gardens, second growth woodlands, mature conifer forests, montane rock gardens, and otherwise pristine stands of old growth noble fir, with elevations ranging from essentially sea level to 1,249 meters. Climates at these locales vary from that of the Mediterranean Willamette Valley floor, where snow rarely occurs and summers are hot and dry, to the summit of the Oregon Coast Range, where deep snow may be present from November through April and summers are cool. The carabid communities in which Nebria brevicollis has been found range from those predominantly of fellow exotic species, e.g., at heavily perturbed sites, to those where it is the only exotic species, such as at the Coast Range summit. Nebria brevicollis is clearly an invasive species in that it is not restricted to anthropogenic habitats, is rapidly expanding its North American range, and can be abundant in essentially pristine settings. What is not yet clear is whether it is or will become a damaging species. Although it is already the most abundant carabid species in some

    The purpose of this study was to assess the protective effects of an ethanol extract derived from the red alga Gracilaria bursa-pastoris (Gmelin) Silva (GBE) on ultraviolet B (UVB)-irradiated human HaCaT keratinocytes. GBE exhibited scavenging activity against intracellular reactive oxygen species that were induced by either hydrogen peroxide or UVB radiation. In addition, both the superoxide anion and the hydroxyl radical were scavenged by GBE in cell-free systems. GBE absorbed light in the UVB range (280-320 nm) of the electromagnetic spectrum and lessened the extent of UVB-induced oxidative damage to cellular lipids, proteins, and DNA. Finally, GBE-treated keratinocytes showed a reduction in UVB-induced apoptosis, as exemplified by fewer apoptotic bodies. These results suggest that GBE exerts cytoprotective actions against UVB-stimulated oxidative stress by scavenging ROS and absorbing UVB rays, thereby attenuating injury to cellular constituents and preventing cell death.

    Detailed studies of larval development of Octolasmis angulata and Octolasmis cor are pivotal in understanding the larval morphological evolution as well as enhancing the functional ecology. Six planktotrophic naupliar stages and one non-feeding cyprid stage are documented in details for the first time for the two species of Octolasmis. Morphologically, the larvae of O. angulata and O. cor are similar in body size, setation patterns on the naupliar appendages, labrum, dorsal setae-pores, frontal horns, cyprid carapace, fronto-lateral gland pores, and lattice organs. Numbers of peculiarities were observed on the gnathobases of the antennae and mandible throughout the naupliar life-cycle. The setation pattern on the naupliar appendages are classified based on the segmentation on the naupliar appendages. The nauplius VI of both species undergoes a conspicuous change before metamorphosis into cyprid stage. The cyprid structures begin to form and modify beneath the naupliar body towards the end of stage VI. This study emphasises the importance of the pedunculate barnacle larval developmental studies not only to comprehend the larval morphological evolution but also to fill in the gaps in understanding the modification of the naupliar structures to adapt into the cyprid life-style.

    Odorant-binding proteins (OBPs) are important parts of insect olfactory systems, and sensitive olfaction is vital for phytophagous insects in host foraging. Electrophysiological studies are helpful in understanding olfactory sensing in Sitobion avenae (Hemiptera: Aphididae), but the functions of odorant-binding proteins in this insect are poorly understood. In this study, we used fluorescence competition assays to measure the binding specificities of SaveOBPs. The results showed that both SaveOBP2 and SaveOBP3 were superior to SaveOBP7 in binding green leaf volatiles. It was unexpected that SaveOBP7 bound trans-β-farnesene strongly, which was known as alarm pheromone of this species. Host volatiles were recognized much more easily by SaveOBP2, and the observed binding activity of SaveOBP2 equaled for tested green leaf volatiles. Our results imply that SaveOBP7 might play a more important role in aphid alarm pheromone discrimination.

    Full Text Available Abstract Cathelicidins are a major family of antimicrobial peptides present in vertebrate animals with potent microbicidal and immunomodulatory activities. Four cathelicidins, namely fowlicidins 1 to 3 and cathelicidin B1, have been identified in chickens. As a first step to understand their role in early innate host defense of chickens, we examined the tissue and developmental expression patterns of all four cathelicidins. Real-time PCR revealed an abundant expression of four cathelicidins throughout the gastrointestinal, respiratory, and urogenital tracts as well as in all primary and secondary immune organs of chickens. Fowlicidins 1 to 3 exhibited a similar tissue expression pattern with the highest expression in the bone marrow and lung, while cathelicidin B1 was synthesized most abundantly in the bursa of Fabricius. Additionally, a tissue-specific regulatory pattern was evident for all four cathelicidins during the first 28 days after hatching. The expression of fowlicidins 1 to 3 showed an age-dependent increase both in the cecal tonsil and lung, whereas all four cathelicidins were peaked in the bursa on day 4 after hatching, with a gradual decline by day 28. An abrupt augmentation in the expression of fowlicidins 1 to 3 was also observed in the cecum on day 28, while the highest expression of cathelicidin B1 was seen in both the lung and cecal tonsil on day 14. Collectively, the presence of cathelicidins in a broad range of tissues and their largely enhanced expression during development are suggestive of their potential important role in early host defense and disease resistance of chickens.

    Full Text Available Aim: To evaluate the effect of different levels of High Bentonite on growth performance, organ weight and serum biochemistry in broiler fed on diets containing aflatoxin. Materials and Methods: A total of 360 day-old commercial broiler chicks were divided at random into 8 dietary treatment groups of 42 chicks each having 3 replicates. Dietary levels of aflatoxin (0.5 ppm and High-grade bentonite (0.5, 0.75 and 1.00% were tested in a completely randomized design manner, forming a total of 8 dietary treatments each with three replicates. Body weight and feed intake were recorded weekly. At 5 wk, six birds from each treatment were sacrificed and liver, kidney, gizzard, pancreas, spleen, bursa of Fabricius and thymus were extracted and weighed. The serum samples were analyzed for total proteins, uric acid, serum albumin, serum globulin and the activities of gamma glutamyl transferase (GGT, alanine amino transferase (ALT and for antibody titers against Newcastle disease (ND and infectious bursal disease (IBD using ELISA technique. Results: A significant (P<0.05 decrease in body weight, feed consumption, relative weights of bursa, thymus, serum protein, anti body titers against NDV and IBDV, and increase in FCR, mortality, relative weight of liver, kidney, and the activity of Gamma Glutamyl Transferase (GGT was observed. However, the relative weights of gizzard, pancreas, spleen, serum albumin, uric acid and the activity of Alanine Amino Transferase (ALT were not influenced by inclusion of AF or HGB. Conclusion: The addition of HGB restored the harmful effects of AF on body weight, feed consumption, FCR, mortality, relative weight of liver, kidney, serum protein, IBDV and NDV. Supplementation of high grade bentonite at 1.0 per cent level was found to be beneficial in ameliorating the adverse effects of aflatoxin (AF in broiler chickens. [Vet World 2013; 6(6.000: 313-317

The above karyotype was encountered along with another in which 2n = 28 (X0, male and 2n = 29 (XX, female in a population from the outskirts of Rio Claro city (São Paulo State, Brazil. Of eight specimens studied, five had the heterozygous karyotype involving a translocation and three had the basic karyotype. There were no individuals homozygous for the rearrangement. The heterozygous karyotype was the result of a chromosomal rearrangement between chromosome pairs 6 and 10, both of which were initially submetacentric. The members of the sixth pair normally have two constrictions in the small arm, with a satellite at the chromosome tip. The chromosome of the tenth pair involved in the translocation was generally submetacentric and probably underwent a pericentric inversion which transported the centromere to a subterminal position before being translocated. In this case, the long arm of the inverted chromosome of the tenth pair was translocated with the satellite of a member of the sixth pair.A espécie Gryllus assimilis L. apresenta 2n = 29, X0 (macho e 2n = 30, XX (fêmea, porém em alguns indivíduos coletados na cidade de Rio Claro, São Paulo, Brasil, foram encontrados dois cariótipos distintos: o cariótipo básico e outro rearranjado, com 2n = 28, X0 e 2n = 29, XX.

    [Objectives] We examined interactions between H. vigintioctopunctata and three isogenic tomato (Lycopersicon esculentum) genotypes with different jasmonic acid (JA) pathways. [Methods] The tomato genotypes were; suppressor of prosystemin-mediated responses2 (spr2) mutant plants, 35s prosystemin (35s) plants, and wild type (Wt) plants. Activity of protease inhibitors (PI) and lipoxygenase (LOX) and dynamic change in relative gene expression of the three kinds of enzymes were tested to study the defense signal pathway induced by H. vigintioctopunctata in tomatoes, and the role of jasmonic acid (JA) in the plant defense process. [Results] Major results were; activity and gene expression of PI and LOX in 35s type tomatoes were significantly higher than in the other two varieties whereas the spr2 type tomato had the lowest level of PI expression. Different periods of exposure to H. vigintioctopunctata showed that the highest PI and LOX activity occurred in 35s and wt type tomatoes 24 h and 6 h after infestation, respectively. There was no significant temporal change in enzyme activity in spr2 type tomatoes. There were no significant differences in PAL activity and relative gene expression in the three tomato varieties. In the process of feeding on plants by H. vigintioctopunctata, PAL activity initially increased then declined after 48 h. No significant changes in PAL activity and gene expression were observed in systemic leaves. PI and LOX were more sensitive to insect herbivory than PAL. [Conclution] 35s tomatoes are to a certain degree resistant to H. vigintioctopunctata and jasmonic acid (JA) plays a role in this resistance.%【目的】研究茉莉酸合成相关基因在番茄抗茄二十八星瓢虫 Henosepilachna vigintioctopunctata Fabricius 中的作用,探讨茉莉酸信号因子在植物防御过程中起到的作用。【方法】利用3种基因型番茄茉莉酸合成缺失突变体 spr2、茉莉酸合成过量表达体35s、野生型番茄 Wt

    Full Text Available Currently, infectious bursal disease (IBD is a highly contagious disease leading to huge economic losses in poultry industry. Our objective was to investigate potential therapeutic effects of the combined extracts of Rhizoma Dryopteridis crassirhizomatis and Fructus mume (RDCFM against IBDV infection. Seventy-two 4-week-old SPF chickens were randomly divided into six groups and inoculated intranasally with 0.2 ml of 102.5 EID50 of IBDV strain CJ801. Twenty-four hours post infection, the birds were orally administered with 400, 200 and 100 mg/kg BW of RDCFM, respectively, 125 mg/kg Astragalus polysaccharide (ASP and saline water, respectively for 5 days and then monitored daily for 10 days. Finally, the remaining birds were euthanized to collect the sera for detecting antibodies and immune organs for determining the immune organs index as well as virus loads. The herbal extracts improved survival rate and relative body gain rate. Virus loads in bursa of Fabricius in herbal treated groups decreased significantly while higher antibody levels were detected in the three RDCFM groups as compared to those of ASP and infection group. These results implied that chickens administered with 100-200 mg/kg of RDCFM for 5 days could improve protection against IBDV infection and RDCFM may be a promising alternative to ASP and egg yolk antibody.

    One-hundred-seventy-two serum samples, collected sequentially from four flocks of egg- and meat-type chickens, were evaluated for antibodies to multiple infectious agents by enzyme-linked immunosorbent assay (MELISA). The MELISA system used provided simultaneous measurement of antibody titers against avian infectious bronchitis (IB), infectious bursal disease (BD), Newcastle disease, avian encephalomyelitis and reovirus infections, and Mycoplasma gallisepticum. The use of computer-generated graphic print outs of relative MELISA titers provided immediate visulization of over 740 data points and convenient detection of any temporal changes in median titer class (MTC). The temporally changing MTC, or flock profiles obtained, indicated that negligible or waning IB immunity may be a common occurrence in previously vaccinated commercial chickens. These profiles further suggested that, despite no IB revaccination, these same flocks experienced episodes of reexposure to IB which otherwise may have been difficult to detect by conventional clinical or diagnostic laboratory protocols. MELISA profiles and sequential histologic examinations of bursas of Fabricius also provided evidence of a possible BD vaccination problem in young chickens that also experienced excessive losses from coccidiosis, ulcerative enteritis, and Marek's disease. Short sampling intervals were found to foster the detection and definition of fluctuations in MTC which otherwise may have been missed. PMID:4048057

    Marek's disease virus (MDV), which is the causative agent of Marek's disease (MD), is shed by infected chickens and transmitted to other chickens through the respiratory route. Experimental reproduction of MD has been commonly done either by intra-abdominal inoculation of cell-associated MDV or by exposure to MDV-infected 'seeder' chickens. The former method does not mimic the natural route of MDV infection, whereas the latter method suffers from lack of uniformity in the timing and amount of virus transmission from seeder chickens to susceptible birds. The aim of the present study was to establish an infection model of MDV that mimics the natural route of infection. Here we report that when chickens were exposed for 20 min to aerosols (particle size 1.91 microm) of cell-free MDV suspensions containing 1280 plaque-forming units/ml, which were generated using a nebulizer, pathological and clinical signs of MD were observed in 95%-100% of the aerosol-exposed chickens by 21 days post-infection (dpi). Chickens that were exposed to aerosols and sampled at 1, 2, 3, 10, and 21 dpi showed MDV replication as early as 1 dpi in lungs as well as in other tissues such as spleen and bursa of Fabricius. This infection model will facilitate the studies directed to elucidate MDV-host interaction at the site of virus entry. PMID:19848077

    Full Text Available Newcastle disease (ND is caused by avian paramyxovirus-1 which belong to Avulavirus genus and Paramyxoviridae family. The birds have abnormalities in humoral (bursa fabricius and cellular (thymus and spleen lymphoid organs. Lesions decrease the immune system. Immune system consists of non-specific and specific immune systems. The main components of non-specific immunity are physical and chemical barrier (feather and skin or mucosa, phagocytic cells (macrophages and natural killer, protein complement and the mediator of inflammation and cytokines. Interferons (IFNs belong to a group of cytokines that play a major role in the nonspecific or innate (natural immunity. The virulent ND virus encodes protein of V gene can be suppressed IFN type I. This leads to non-specific immune system fail to respond to the virulent strains resulting in severe pathogenicity. The defense mechanism of the host is replaced by specific immunity (adaptive immunity when natural immunity fails to overcome the infection. The specific immune system consists of humoral mediated immunity (HMI and cell-mediated immunity (CMI. The cells of immune system that react specifically with the antigen are B lymphocytes producing the antibodies, T lymphocytes that regulate the synthesis of antibodies and T cells as effector or the direct cytotoxic cells. Both non-specific and specific immunities are complementary against the invasion of ND virus in the birds. The objective of this article is to discuss the role of non specific and specific immune system in ND.

    This study was conducted to evaluate the efficacy of citrus fruit oil (CFO; 2.5 g kg(-1)) on the clinicopathological changes in broilers fed with diets containing 1 ppm of aflatoxin (AF). A total of 160 Ross 308 broiler chicks of 1-day-old were procured from a commercial hatchery, divided randomly on 7th day of age into four groups with two replicates of 20 birds each and fed with basal diet (group A), basal diet + CFO (group B), basal diet + AF (group C) and CFO + basal diet + AF (group D). The gross and histopathological changes in the liver, kidney, spleen, thymus and bursa of Fabricius were investigated and relative organ weights were calculated. Slight to moderate hydropic degeneration, fatty change with the formation of cyst in some cases, periportal necrosis, infiltration of heterophils and mononuclear cells and bile duct hyperplasia were observed in chicks fed with 1 ppm AF-containing diet. The addition of CFO to AF-containing diet moderately decreased the magnitude and severity of lesions (hydropic degeneration and bile duct hyperplasia) in the liver. The supplementation of CFO to the basal diet did not produce any adverse effects in birds.

    Toll-like receptor 5 (TLR5) is responsible for the recognition of bacterial flagellin in vertebrates. In the present study, the first TLR5 gene in duck was cloned. The open reading frame (ORF) of duck TLR5 (dTLR5) cDNA is 2580 bp and encodes a polypeptide of 859 amino acids. We also cloned partial sequences of myeloid differentiation factor 88, 2'-5'-oligoadenylate synthetase (OAS), and myxovirus resistance (Mx) genes from duck. dTLR5 mRNA was highly expressed in the bursa of Fabricius, spleen, trachea, lung, jejunum, rectum, and skin; moderately expressed in the muscular and glandular tissues, duodenum, ileum, caecum, and pancreas; and minimally expressed in the heart, liver, kidney, and muscle. DF-1 or HeLa cells transfected with DNA constructs encoding dTLR5 can activate NF-κB leading to the activation of interleukin-6 (IL-6) promoter. When we challenged ducks with a Herts33 Newcastle disease virus (NDV), mRNA transcription of the antiviral molecules Mx, Double stranded RNA activated protein kinase (PKR), and OAS was up-regulated in the liver, lung, and spleen 1 and 2 days post-inoculation.

    This study had the aim of evaluating the effects of medium-chain fatty acids (MCFA) on performance, carcass characteristics, some blood parameters and antibody titre against sheep red blood cells (SRBC) in quail. A total of 240 quail chicks were allotted to 4 treatments consisting of respectively 0, 1, 2 and 4 g/kg dietary MCFA. There were no significant differences in body weight, feed intake and feed conversion ratio among treatments at different stages of the experiment. MCFAs had no significant effect on breast, thigh, liver, spleen and bursa of Fabricius weight ratios. However, the relative weight of abdominal fat significantly decreased in quail receiving 0.2 and 0.4 MCFA as compared to other treatments. Concentrations of low-density lipoprotein-cholesterol (LDL), triglycerides and total cholesterol were decreased and high-density lipoprotein (HDL)-cholesterol was increased in quail chicks receiving MCFA compared with control quail chicks. The concentrations of SRBC antibody were not statistically different among treatments. It is concluded that MCFA significantly decreased LDL, triglycerides, cholesterol and abdominal fat and increased HDL in quail chicks. PMID:27074264

    Twelve-week-old indigenous chickens, either immune-suppressed using dexamethasone (IS) or non-immune-suppressed (NIS), were challenged with a low virulent strain, Pasteurella multocida strain NCTC 10322(T), and developed clinical signs and pathological lesions typical of chronic fowl cholera. NIS birds demonstrated much more severe signs of fowl cholera than IS birds. With few exceptions, signs recorded in IS and NIS birds were of the same types, but significantly milder in the IS birds, indicating that immune suppression does not change the course of infection but rather the severity of signs in fowl cholera. P. multocida signals by fluorescent in situ hybridization (FISH) were observed between 1 h and 14 days in the lungs, trachea, air sacs, liver, spleen, bursa of Fabricius and caecal tonsils, while signals from other organs mostly were observed after 24 h. More organs had FISH signals in NIS birds than in IS birds and at higher frequency per organ. Many organs were positive by FISH even 14 days post infection, and it is suggested that these organs may be likely places for long-term carriage of P. multocida following infection. The present study has demonstrated the spread of P. multocida in different tissues in chickens and distribution of lesions associated with chronic fowl cholera, and pointed to a decrease of pathology in IS birds. Since dexamethasone mostly affects heterophils, the study suggests that these cells play a role in the development of lesions associated with chronic fowl cholera in chickens.

    The purpose of this study was to evaluate the underlying basis for aflatoxin-induced immunosuppression in the broiler chicken by detecting pathological lesions and apoptosis in thymus, bursa of Fabricius (BF) and spleen. COBB500™ male broiler chicks were randomly allocated to two groups. The control group was fed on a basal corn-based diet while the other group (the AFB group) was fed on a similar diet but the corn was naturally contaminated with aflatoxins B1 and B2. Histopathological examination revealed that in the AFB group there was more nuclear debris in the three immune organs and obvious congestion of red pulp in the spleen, when compared with the control group. Ultrastructural examination showed lesions in the lymphocytes and reticulocytes of the three immune organs, the mucosal epithelium of the BF and the plasmocytes of the spleen. Increased apoptotic cells and an impaired membrane system (including nuclear membrane, mitochondria and endoplasmic reticulum [ER]) could be observed in the three immune organs in birds of the AFB group. In the plasmocytes, dilated rough endoplasmic reticulum contained electron-dense matrix. By flow cytometry, the percentages of apoptosis were significantly higher (P < 0.01) in the three organs of the AFB group than those of the control group. These observations suggested that the lesions of the immune organs were related to the immunosuppression, and that the apoptosis might be initiated by the mitochondrial pathway and ER chaperone pathway.

    We investigated unusual crow mortality in Bangladesh during January-February 2011 at two sites. Crows of two species, Corvus splendens and C. macrorhynchos, were found sick and dead during the outbreaks. In selected crow roosts, morbidity was ~1 % and mortality was ~4 % during the investigation. Highly pathogenic avian influenza virus H5N1 clade 2.3.2.1 was isolated from dead crows. All isolates were closely related to A/duck/India/02CA10/2011 (H5N1) with 99.8 % and A/crow/Bangladesh/11rs1984-15/2011 (H5N1) virus with 99 % nucleotide sequence identity in their HA genes. The phylogenetic cluster of Bangladesh viruses suggested a common ancestor with viruses found in poultry from India, Myanmar and Nepal. Histopathological changes and immunohistochemistry staining in brain, pancreas, liver, heart, kidney, bursa of Fabricius, rectum, and cloaca were consistent with influenza virus infection. Through our limited investigation in domesticated birds near the crow roosts, we did not identify any samples that tested positive for influenza virus A/H5N1. However, environmental samples collected from live-bird markets near an outbreak site during the month of the outbreaks tested very weakly positive for influenza virus A/H5N1 in clade 2.3.2.1-specific rRT-PCR. Continuation of surveillance in wild and domestic birds may identify evolution of new avian influenza virus and associated public-health risks.

    Abstract. Trichogramma species are an important group of parasitoids that attack especially lepidopteran eggs. The quality and performance of this natural enemy may be influenced by factors such as alternative host used in the massal rearing, and differences in the temperature and photoperiod. Based on this, this study aimed to evaluate the number of parasitized eggs, % of females that parasitized, % emergence, sex ratio and number of individuals of Trichogramma galloi Zucchi per egg of Diatraea saccharalis (Fabricius in the presence and absence of light. The experimental design was completely randomized with two treatments (light and dark and 60 replications, being each experimental unit composed by 40 eggs of D. saccharalis which were placed in a glass tube with one female of T. galloi with age of 24 hours, previously fed with honey. The experiment was carried out at 25 ± 2 °C and 70 ± 10% relative humidity. In each one of the treatments, the parasitoid was removed from the tube after 12 hours. The highest number of parasitized eggs (12.9 and % of females that parasitized (83.3% was observed during the period with light. For the emergence, sex ratio and number of individuals per egg, there was no statistical difference. The results showed that the presence of light is essential for this biological control agent.

  17. A major host plant volatile, 1-octen-3-ol, contributes to mating in the legume pod borer, Maruca vitrata (Fabricius) (Lepidoptera: Crambidae)

    2015-10-01

    Previous studies on the legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae), a serious pest of cowpea, Vigna unguiculata (L.) Walp. (Fabales: Fabaceae), in sub-Saharan Africa have focused on sex pheromones, but the role of the host plant on sexual behavior has not been explored. We investigated this interaction in the laboratory using behavioral assays and chemical analyses. We found that the presence of cowpea seedlings and a dichloromethane extract of the leaf increased coupling in the legume pod borer by 33 and 61 %, respectively, compared to the control, suggesting the involvement of both contact and olfactory cues. We used coupled gas chromatography-electroantennographic detection (GC/EAD) and GC-mass spectrometry (GC/MS) to identify compounds from the cowpea leaf extract, detected by M. vitrata antenna. We found that the antennae of the insect consistently detected four components, with 1-octen-3-ol identified as a common and dominant component in both the volatiles released by the intact cowpea plant and leaf extract. We therefore investigated its role in the coupling of M. vitrata. In dose-response assays, 1-octen-3-ol increased coupling in M. vitrata with increasing dose of the compound compared to the control. Our results suggest that the cowpea volatile 1-octen-3-ol contributes to M. vitrata sexual behavior.

    Objective] Genome-wide association studies were performed by using the chicken 60k high density SNP array for nine immune traits in Beijing-You chicken and identification of candidate genes and loci responsible for these traitswere identified. Here, by treating Beijing-You chicken with polyinosinic acid-polycytidylic acid, Poly(I:C) and Salmonella enteritidis (SE), several candidate genes were further studied based on authors’ GWAS result, includingCD1b,BMA1(B locus M alpha chain 1),TRIM27 (tripartite motif-containing 27) andZNF692(zinc finger protein 692).[Method] Eighty 12-d-old Beijing-You Chickens were divided into three groups: the control group, Poly(I:C) treatment and SE treatment groups. All the experimental birds were reared in isolated facility. The treatment groups were, respectively, injected intramuscularly into the breast with 0.5 mL of Poly(I:C) and SE bacterial suspension containing 108 CFU and the control group was given 0.5 mL saline. Chickens were sacrificed at 12 h, 24 h, 3 and 6 days of post infection (DPI). Blood samples were collected and serum was stored. The bursa of Fabricius, thymus and spleen were rapidly removed to test inflammatory factors and gene expression.[Result] The weight was significantly lower than control group 24 h post infection (P<0.01) and temperature of chickens was significantly changed in 24 h after treatments. In serum, concentrations of IFN-α, IL-4 and IL-6 were significantly higher than the control and reached a peak at 24 h or 3 d (P<0.01). TNF-αincreased in all periods and significantly higher than the control group after 3 days. The expression of candidate geneCD1b was not tissue-specific, butBMA1,TRIM27 andZNF692 were highly expressed in thymus and bursa fabricius. In thymus, the expression of CD1bwas significantly different between two treatments at 12 h and 24 h post infection. When treated with SE, the expression of CD1b was significantly increased and reached a peak at 24 h (P<0.01). The mRNA expression

    Full Text Available Aim: To study the efficacy of Na-butyrate encapsulated in palm fat on performance of broiler chickens experimentally infected with necrotic enteritis (NE with the determination of its protective effect against the changes in the gene expression profiles and deoxyribonucleic acid (DNA fragmentation. Materials and Methods: A total of 800 one-day-old male Arbor Acres Plus broiler chickens were randomly allocated into four groups for 5 weeks. Na-butyrate was supplemented at dosages of 1 kg/ton for starter diet, 0.5 kg/ton for grower diet, and 0.25 kg/ton for finisher diet (presence or absence. Birds of groups 1 and 2 were inoculated by crop gavages with 4×108 CFU/ml/bird of Clostridium perfringens in phosphate buffered saline for 4 successive days, from 14 to 17 days of age to produce NE. Results: Addition of Na-butyrate, encapsulated in palm fat, to ration of experimentally infected broilers with NE resulted in increased final body weight, at 35 days of age, reduced total feed consumption, improved feed conversion ratio, reduced cumulative mortality, and increased production number. There were increased intestinal diameter, intestinal length, and significantly increased the weight of bursa of Fabricius(BF with higher hemagglutination inhibition titers against Newcastle disease (ND vaccination versus untreated infected and untreated negative control birds. The results showed increased expression levels of alpha-toxin and glyceraldehyde-3-phosphate dehydrogenase in the bursa tissues of broilers infected with C. perfringens. However, the expression levels of these genes in broilers treated with Na-butyrate were similar to the non-infected control group. Supplementation of broilers with Na-butyrate increased the expression level of insulin-like growth factor-1 (IGF-1 and decreased the DNA fragmentation induced by C. perfringens. Conclusion: Na-butyrate significantly improved chicken broiler body weights, increased relative weights of BF, increased

    Pigeon circovirus (PiCV) infection and young pigeon disease syndrome (YPDS), associated with high morbidity and mortality, have been recognized in young racing pigeons from large portions of Central Europe. There exist a number of data indicating that YPDS is a consequence of PiCV infection and subsequent immunosuppression. In order to prove PiCV to be one of the crucial factors of YPDS, an experimental infection with PiCV was performed under controlled conditions. Twenty-four domestic pigeons (Columba livia forma domestica) were divided into two groups with 12 pigeons each; an infection group and a control group. All birds were between their fourth to eighth week of life. Pigeons in the infection group were infected both intramuscularly and orally with PiCV purified from naturally infected birds, while pigeons in the control group received a placebo. To test a possible influence of the PiCV infection on the immune system, the animals in both groups were vaccinated simultaneously, on the same day, against PMV-1 (Lasovac plus, IDT, Dessau-Tornau, Germany). Weekly virologic testing showed a viraemic period, and excretion of the infection virus, in pigeons in the infection group. Replication of PiCV could be proved on the basis of histologic findings of multiglobular inclusion bodies, mainly observed in macrophages of the bursa of Fabricius. A PiCV, genetically distinct from the experimental virus, was detected in the control group by polymerase chain reaction (PCR) testing, but any histologic findings comparable to the infection group were absent. None of the pigeons revealed clinical signs of illness, or hints that immunosuppression had occurred, regardless of their group. The absence of stressful conditions, considered as a trigger for the development of YPDS, may be responsible for the failure of disease reproduction in our infection model.

Three broilers of each group were challenged with a pathogenic strain of NC, at 42 day of age, without signs of disease after 72 hours when the positive control group was dead. Gross and microscopic lesions were not detected in the bursa of Fabricius or thymo. [thymo sounds like short hand for something that should be properly named.] Very good animal weight, conversion and efficiency results were observed in all the groups. New studies using a fixed dose of porinas, larger numbers of broilers and the establishment of protective levels of IgA against NC challenge are recommended.

    2016-07-01

    Common eider Somateria mollissima L. 1758, subsp. borealis, is widely distributed along the coasts of Iceland. In this study association of parasite infections and food composition was studied among 40 females and 38 males (66 adults, 12 subadults), shot under license on four occasions within the same year (February; before egg-laying in May; after the breeding period in late June; and in November) in Skerjafjörður, SW Iceland. Parasitological examinations revealed 31 helminth species (11 digeneans, ten cestodes, seven nematodes, and three acanthocephalans). Distinct digenean species parasitized the gallbladder, kidney and bursa of Fabricius, whereas other helminths parasitized the gastrointestinal tract. Thirty-six invertebrate prey species were identified as food; waste and bread fed by humans, were also consumed by some birds. Amidostomum acutum was the only parasite found with a direct life cycle, whereas other species were food transmitted and ingested with different invertebrate prey. Opposite to females male birds rarely utilized periwinkles and gammarids as a food source. As a result, Microphallus and Microsomacanthus infection intensities were low except in February, when subadult males were responsible for an infection peak. Females caring for young increased their consumption of periwinkles close to the littoral zone in June; during pre-breeding, females also increased their gammarid intake. As a consequence, Microphallus and Microsomacanthus infection intensities temporarily peaked. Increased food intake (including Mytilus edulis) of females before the egg-laying period resulted in twofold higher Gymnophallus bursicola infection intensity than observed for males. Profilicollis botulus infection reflected seasonal changes in decapod consumption in both genders. Different life history strategies of males and females, especially before and during the breeding season and caring of young, and during molting in distinct feeding areas in summer, promote

    Trimethyltin chloride (TMTC) and triethyltin chloride (TETC) were fed to mallard (Anas platyrhynchos) ducklings for 73 to 75 d, beginning when ducklings were 3 to 4 d old. Diets were mixed to contain 0,0.5,5 or 50 ppm Sn as either TMTC or TETC. Mortality occurred only in the 5 ppm (2/5 ducklings) and 50 ppm (5/5 ducklings, all dying within 5 d) TMTC groups. Death was preceded by cephalic tremors, lethargy and ataxia; these clinical signs also were observed in surviving ducklings from the 5 ppm TMTC group, but not the 0.5 ppm TMTC group. Ducklings fed 5 and 50 ppm Sn as TMTC exhibited degeneration of the large neurons of the pons, medulla oblongata, gray matter of the spinal cord and pyramidal cells of the cerebral cortex. TETC-fed ducklings showed few signs of clinical toxicosis. Ducklings fed 50 ppm Sn as TETC exhibited mild to severe vacuolization of the white matter of the brain and spinal cord; these lesions were not present in ducklings fed 5 ppm Sn as TETC. Liver, spleen, kidney, thymus, bursa of Fabricius and skeletal muscle presented no abnormal histopathology for either organotin compound. Hematocrit, hemoglobin and plasma aspartate aminotransferase; alanine aminotransferase; lactate dehydrogenase; alkaline phosphatase; and cholinesterase values were determined for the 5- and 50- ppm TMTC and TETC groups, and were not different from those of controls (p < 0.05). Lesions and clinical signs of toxicosis in ducklings were consistent with those described for mammals exposed to TMTC and TETe. The effect threshold for TMTC in ducklings appears to exceed current environmental concentrations. Environmental concentrations of TETC have not been reported.

    Species of the family Prosthogonimidae are considered the most pathogenic poultry trematodes worldwide, affecting particularly low intensity farming in rural areas. Adults of Prosthogonimus occur mainly in the bursa of Fabricius, oviduct and cloaca of ducks, geese, fowl and other birds feeding at least occasionally on dragonflies or damselflies (Odonata). We analyzed the central European species of the Prosthogonimidae, namely Prosthogonimus cuneatus, Prosthogonimus ovatus, Prosthogonimus pellucidus and Prosthogonimus rarus. We sequenced three nuclear (ITS2) and mitochondrial (CO1, ND1) DNA loci of four species isolated from Anas clypeata, Anas strepera, Anas platyrhynchos, Aythya ferina, Passer domesticus and Turdus merula. Intra- and inter-specific sequence variability revealed that all four species represent distinct well-defined entities. Our data, combined with previously published studies, suggest the return of the name Prosthogonimus rarus Braun, 1901 for Schistogonimus rarus (Braun, 1901). The genus name Schistogonimus Lühe, 1909 is considered a junior synonym of Prosthogonimus Lühe, 1899. We identified the existence of two clades, one represented by P. cuneatus and P. pellucidus, and another one formed by P. ovatus and P. rarus. We also provide comparative measurements of these four central European prosthogonimids, and address their tissue specificity, host-specific prevalence (based on the extensive bird cohort examined in years 1962-2014), and for some bird hosts we address also differences in the prevalence of Prosthogonimus spp. in natural and near-natural wetlands in comparison with fishponds utilized for intense carp production. We provide an updated key to European Prosthogonimus spp. based on their morphological characters. PMID:25724855

    To evaluate and compare the effects of Bacillus coagulans-fermented Ginkgo biloba (FG) and nonfermented Ginkgo biloba (NFG) on the immunity status of broiler chickens, 180 1-d-old female Arbor Acres chicks were divided into 3 groups and fed either a basal diet, a basal diet supplemented with 0.3% NFG, or a basal diet supplemented with 0.3% FG. Blood samples were taken on the seventh (before vaccination), 14th, 21st, 28th and 35th day for the assessment of serum IL-18 and interferon γ (IFN-γ) levels by ELISA. In addition, Newcastle disease antibody titer analysis was made via hemagglutination and hemagglutination inhibition test methods. On d 35, 6 chickens from each group were sacrificed and the thymus, liver, spleen, small intestine (jejunum segment), cecum, and bursa of Fabricius from each chicken were removed for analysis. RNA was isolated for defensin expression detection by real-time PCR (q-PCR). The results showed that serum IL-18 and IFN-γ levels decreased after treatment with NFG and FG compared with untreated control chickens. The ND antibody titers did not differ significantly between the 3 groups on the seventh, 14th, 21st and 28th day; however, on the 35th day, the ND antibody titers of the NFG and FG chickens were both significantly higher than those of control group chickens. Defensin RNA expression levels were inhibited by NFG; however, they were induced by FG. In conclusion, fermentation of Ginkgo biloba with Bacillus coagulans can promote the beneficial effect of Gingko biloba on the immunity status of broiler chickens.

    This study evaluated the effects of dietary methylmercury (MeHg) on immune system development in captive-reared nestling American kestrels (Falco sparverius) to determine whether T cell–mediated and antibody-mediated adaptive immunity are targets for MeHg toxicity at environmentally relevant concentrations. Nestlings received various diets, including 0 (control), 0.6, and 3.9 μg/g (dry wt) MeHg for up to 18 d posthatch. Immunotoxicity endpoints included cell-mediated immunity (CMI) using the phytohemagglutinin (PHA) skin-swelling assay and antibody-mediated immune response via the sheep red blood cell (SRBC) hemagglutination assay. T cell– and B cell–dependent histological parameters in the spleen, thymus, and bursa of Fabricius were correlated with the functional assays. For nestlings in the 0.6 and 3.9 μg/g MeHg groups, CMI was suppressed by 73 and 62%, respectively, at 11 d of age. Results of this functional assay were correlated with T cell–dependent components of the spleen and thymus. Dose-dependent lymphoid depletion in spleen tissue directly affected the proliferation of T-lymphocyte populations, insofar as lower stimulation indexes from the PHA assay occurred in nestlings with lower proportions of splenic white pulp and higher THg concentrations. Nestlings in the 3.9 μg/g group also exhibited lymphoid depletion and a lack of macrophage activity in the thymus. Methylmercury did not have a noticeable effect on antibody-mediated immune function or B cell–dependent histological correlates. We conclude that T cell–mediated immunosuppression is the primary target of MeHg toward adaptive immunity in developing kestrels. This study provides evidence that environmentally relevant concentrations of MeHg may compromise immunocompetence in a developing terrestrial predator and raises concern regarding the long-term health effects of kestrels that were exposed to dietary MeHg during early avian development.

    Full Text Available To evaluate the effect of different stocking density on broiler performance two repeated experiments were conducted in a conventional and an environmentally controlled house using a total of 10,232 broiler chickens. In each experiment, a total of 5,116 one-day old Ross 308 broiler chickens were randomly distributed to 16 floor pens arranged within each house at density of 16, 18, 20 or 22 birds/m2. Results showed that the broiler chickens grown in environmentally controlled house had greater (p<0.05 weight gain, kg body weight (BW/m2, production efficiency index (PEI and spleen relative weight at day 42 and also had lower (p<0.05 feed conversion ratio and mortality rate during 21 to 42 and 1 to 42 days of age than those reared in conventional house. Weight gain, feed intake and PEI decreased (p<0.05 and kg BW/m2 and carcass yield increased (p<0.05, when broiler density increased more than 20 birds/m2. House type and stocking density had no effect on relative weights of liver, abdominal fat, bursa of Fabricius, and litter pH and ammonia emission. However, higher litter moisture in conventional house led to a greater (p<0.05 incidence of foot pad lesions and hock burns, which intensified with increased density. In conclusion, broiler chickens reared in environmentally controlled house had superior performance, higher liability, and lower litter moisture content and foot lesions. Moreover, broiler rearing at the density of 22 birds/m2 adversely affected growth performance and foot quality, despite the greater kg BW/m2 compared to broilers grown at lower densities.

    Full Text Available The aim of the present study was to comparatively evaluate hemogram, blood serum components and anatomopathologic alterations in commercial layers experimentally challenged with an attenuated vaccine candidate strain (SG∆cobS∆cbiA and other two pathogenic strains (SGDcobS and SGNalr of Gallinarum (SG. In total, 280 commercial layers were randomly divided into 4 groups (G1, G2, G3 and G4. At five days of age, birds from groups G1 received approximately 107 colony forming units (CFU of SGDcobS; meanwhile birds from group G2 and G3 received the same dose of SGNalr and SG∆cobS∆cbiA, respectively. Birds from G4 were not infected. At 24 hours before (DBI and 24 hours after (1 DAI, and three (3 DAI, five (5 DAI, seven (7 DAI ten (10 DAI, and fifteen (15 DAI days after the infection, 10 birds of each group were humanely killed and blood samples collected to hematological and serum tests. Samples of liver, spleen, thymus, bursa of Fabricius, kidney and heart were also collected for the histological examination. Birds inoculated with SGDcobS and SGNalr showed similar alterations in hemogram, blood serum components and anatomopathologic exams. On the other hand, the exams of birds inoculated with SG∆cobS∆cbiA strain were similar to those of the uninfected birds. However, changes could be noticed in levels of uric acid and cholesterol during the course of the infection of birds from G3. Decrease in levels of light IgG 3 DAI was also observed in birds from this group. Pyknosis in kidney cells was a microscopic alteration found in birds from G3. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SG∆cobS∆cbiA strain.

    Common eider Somateria mollissima L. 1758, subsp. borealis, is widely distributed along the coasts of Iceland. In this study association of parasite infections and food composition was studied among 40 females and 38 males (66 adults, 12 subadults), shot under license on four occasions within the same year (February; before egg-laying in May; after the breeding period in late June; and in November) in Skerjafjörður, SW Iceland. Parasitological examinations revealed 31 helminth species (11 digeneans, ten cestodes, seven nematodes, and three acanthocephalans). Distinct digenean species parasitized the gallbladder, kidney and bursa of Fabricius, whereas other helminths parasitized the gastrointestinal tract. Thirty-six invertebrate prey species were identified as food; waste and bread fed by humans, were also consumed by some birds. Amidostomum acutum was the only parasite found with a direct life cycle, whereas other species were food transmitted and ingested with different invertebrate prey. Opposite to females male birds rarely utilized periwinkles and gammarids as a food source. As a result, Microphallus and Microsomacanthus infection intensities were low except in February, when subadult males were responsible for an infection peak. Females caring for young increased their consumption of periwinkles close to the littoral zone in June; during pre-breeding, females also increased their gammarid intake. As a consequence, Microphallus and Microsomacanthus infection intensities temporarily peaked. Increased food intake (including Mytilus edulis) of females before the egg-laying period resulted in twofold higher Gymnophallus bursicola infection intensity than observed for males. Profilicollis botulus infection reflected seasonal changes in decapod consumption in both genders. Different life history strategies of males and females, especially before and during the breeding season and caring of young, and during molting in distinct feeding areas in summer, promote

    Fertilized eggs of ring-necked pheasants (Phasianus colchicus) were injected into the albumin or yolk with vehicle or graded doses of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), on day 0 of embryonic development and toxicity was assessed in 1-d-old hatchlings and 28-d-old chicks. The most sensitive effect of in ovo TCDD exposure was induction of hepatic ethoxyresorufin-O-deethylase (EROD) activity in 1-d-old hatchlings. The ED50 for this response was 312 pg TCDD/g egg. Embryo mortality was the most sensitive sign of toxicity. The TCDD dose that caused 50% mortality above control (LD50) when injected into the egg albumin or yolk was 1,354 and 2,182 pg TCDD/g egg, respectively. At egg TCDD doses up to and including 1,000 pg TCDD/g egg, no effect was detected in 1-d-old hatchlings and 28-d-old chicks in body growth, organ weights, carcass morphometrices, incidence of edema, or incidence of histological alterations in the liver, spleen, heart, Bursa of Fabricius, or thymus. Egg TCDD doses as high as 1,000 pg TCDD/g egg also had no effect on cardiac morphometrices or incidence of cardiac malformations in 1-d-old hatchlings, or on antibody-mediated immunity in 28-d-old chicks. The authors conclude that embryo mortality is the most sensitive sign of TCDD toxicity in the ring-necked pheasant following in ovo exposure.

    The present study investigated the effects of night restricted feeding of extreme heat diet (EHD) containing heat stress resistance nutrients, with inverse lighting program, on their growth performance in broiler chickens exposed to extreme heat stress (33 ± 2°C). EHD 1 contained soy oil, molasses, methionine and lysine. EHD 2 contained all nutrients of EHD 1 and vitamin C additionally. Three hundred broiler chickens (Ross 308) were randomized into four dietary treatment groups according to a randomized block design on the day they were hatched. The treatment groups were: T1 (EHD 1, 10:00-19:00 dark, 19:00-10:00 light), T2 (EHD 2, 10:00-19:00 dark, 19:00-10:00 light), T3 (EHD 1, 09:00-18:00 dark, 18:00-09:00 light) and T4 (EHD 2, 09:00-18:00 dark, 18:00-09:00 light). The body weight gain of the broilers increased most significantly in T2, followed by T1, T4 and T3 (p immune system, thymus and bursa of Fabricius recorded higher in T1 and T2 than in T3 and T4. The spleen was higher in T1, T2 and T3 than in T4 (p acid, propionic acid and total Short chain fatty acid were significantly higher in the order of T2, T1, T3 and T4. Butyric acid, isobutyric acid, valeric acid and isovaleric acid were higher in T4 and T3 than in T1 and T2 (p < 0.05). PMID:27097436

    In order to study the nosogenesis of the Remerella anatipestifer disease, the pathological model of Remerella anatipestifer disease was established throught artificially infected experimental ducklings at 14 days of age with Remerella anatipestifer serotype Ⅰ . The dynamic pathobiology changes of the heart,liver, spleen,lung, kidney, brain, thymus, bursa of Fabricius, pancreas were observed with the ordinary pathobiology method at 6,12,24,36,48, 60,72,84 h and 7 d after infected. The result showed that the pathological model of Remerella anatipestifer disease was successfully established after the experimental ducklings were artificially infected the Remerella anatipestifer serotype Ⅰ through the craw injection and the trachea injection. The delitescence,the early death time,the death peak time, the stoped death time, the mortality of the enteron infection were 6 h, 24 h, 36-72 h, 72 h and 85% respectively. The delitescence,the early death time, the death peak time, the stoped death time, the mortality of the respiratory path infection were 12 h,24 h,60-84 h,84 h and 65 % respectively. The delitescence of the respiratory path infection was more 6 h, the death peak time later 24 h, the mortality lower 20%, than those of the enteron infection. The pathological changes were first observed in the heart and the liver,then the lung,kidney,brain and pancreas the thymus, bursa of Fabricius and spleen the last. The histological pathological changes were earlier about 6-12 h than the anatomic pathological changes. The fibroid pericarditis was earlier about 24 h than the fibroid hepatitis, respectively 24 h and 48 h after infection. All organs first represented the hyperaemia and the slight tumescence, then the serofluid and fibroid inflammation, the last the broad hemorrhage. The histiocytes first represented the tumefaction, the last the granular denaturalization, the vesicular denaturalization, the adipose denaturalization, the last the putrescence, finally the

    Full Text Available The aim of this study was to investigate the effect of diet type, supplementation diet with an essential oil mixture (EOM, and bird gender on the growth performance, carcass yield, internal organ weight, immune response, and small intestine histology of broiler chickens. To do this, a 2x2x2 factorial arrangement was designed. The variables used were: two diet types (based on either wheat or corn, 2 feed additives (with or without EOM, and gender (male or female. EOM supplementation in the diet decreased body weight in corn-fed male birds at Days 21 and 42, but not in those fed the wheat-based diet, signifying a diet x EOM x gender interaction. Cumulative feed intake was not influenced by either the diet type or EOM. The feed conversion ratio was not affected by diet type, whereas EOM improved feed conversion ratio over the 42-day growth period. Feeding birds on wheat decreased the carcass yield while it increased relative small intestine and large intestine weight. Relative weights of liver, bursa fabricius and serum infectious bursal disease (IBD and Newcastle disease (ND titers were not affected by any of the variables studied. EOM supplementation and feeding birds on corn increased jejunal villus height at both 21 and 42 days of age, while bird gender showed no effect. In general, EOM positively influenced body weight gain and efficiency of feed conversion in broiler chickens. Birds receiving the corn-based diet were more efficient in converting feed to body mass as compared to those fed on the wheat-based diet.

    Full Text Available A trial has been performed to evaluate the effects of dietary verbascoside (VB on the growth performance, blood traits, meat quality and histological features of broiler chickens. Seventy-two male broiler chickens (Ross 708 were divided into three experimental groups (8 replicates: a control group (C; basal diet, a low VB group (LVB; basal diet+2.5 mg VB/kg feed and a high VB group (HVB; basal diet+5.0 mg VB/kg feed. The animals were kept in cages, three birds per cage. The trial lasted 35 days. Growth performance and carcass yield were recorded. Blood samples were collected at day 35 in order to evaluate the blood, serum and plasma parameters. As a result of this study, growth and slaughter performances were not affected by the dietary treatments. The LVB and HVB groups showed significantly lower concentrations of total protein (P=0.000, albumin (P=0.000, α-globulin (P=0.001 and β-globulin (P=0.023 than C group. The heterophil to lymphocyte ratio was higher in HVB group than in LVB and C groups (P=0.005. The thiobarbituric acid reactive substances results indicated lower lipid oxidation in the LVB group than in C group. The most relevant histological feature was the lymphoid depletion observed in the thymus and bursa of Fabricius in LVB and HVB. Other studies are still needed to identify the optimal dosage and exposure time of VB dietary supplementation and to further investigate the effects of VB on lymphoid tissue as well as to establish the VB antioxidant effect on broiler chickens.

    Abstract. Some neotropical social wasps which are associated with some vertebrates and other insects like ants, and these interactions are reported for decades, but little is known about the presence of these in the Caatinga and Atlantic Forest. This study describes the first association's record between nests of Polybia rejecta (Fabricius wasp and Azteca chartifex Forel ants in the transition area of the Atlantic Forest and Caatinga in Rio Grande do Norte. The observations were in a private forest in Monte Alegre, from October 2009 to September 2014 through active search for colonies, use of ad libitum method, photography and collection of specimens with traceability. In the study area were found four active colonies and one abandoned of P. rejecta, all associated with nests of A. chartifex with approach of 20-30 cm. It was found that when the colony of P. rejecta was disturbed, they became aggressive towards the disturbance object, whereas the ants gathered in order to fend off a potential predators. These interactions appear to benefit wasps and ants, it is assumed that is possible that wasps attack ants's predators, whereas the ants attack the wasps's predators. This study corroborates the hypothesis that the association between the social wasps P. rejecta and A. chartifex ants is beneficial for both species, and probably the wasps are the most benefited, but also shows the non-exclusivity of this association for the biomes up then reported.

    A virulent strain PS-1 with high infectivity was isolated from the natural death larvae of Phyllotreta striolata. The strain PS-1 was characterized as Serratia marcescens based on its morphological, cultural, biolog identification system and 16S rDNA sequences analysis. The larvae of P. striolata were fed with turnip cubes which had been dipped in suspension culture of different concentrations (3×104, 3×106 and 3×108 cfu/mL) of S. marcescens PS-1 for 24 h. The corrected mortality rates were 36.1%, 63.9% and 75.0% at 4 d post-treatment, respectively. The LC50 was 7.98×106, 4.27×106 and 8.02×105 cfu/mL at 2, 3 and 4 d. The corrected mortality rate of P. striolata larvae fed with cabbage leaves which had been dipped in suspension culture of S. marcescens PS-1 under the concentrations of 1×108 cfu/mL was 23.25%at 12 d post-treatment. When the eggs of P. striolata were dipped in suspension culture of different concentrations (1×105, 1×107and 1×109 cfu/mL) of S. marcescens PS-1, there was no significant difference in the hatching rate between the control and treatments. The results suggest that S. marcescens PS-1 which has a strong virulence against the larvae and adults of P. striolata might be a good candidate as a potential microbial agent for biological control.%从自然死亡黄曲条跳甲幼虫体中分离出1株对黄曲条跳甲幼虫和成虫有较高致病性菌株PS-1。通过病原菌的形态观察、Biolog系统鉴定以及16S rDNA序列测定分析,确定菌株PS-1隶属于肠杆菌科、沙雷氏菌属的粘质沙雷氏菌Serratia marcescens族群。用菌株PS-1浓度为3×104、3×106和3×108 cfu/mL的菌悬液浸泡鲜萝卜块饲喂黄曲条跳甲幼虫24 h,4 d后的校正死亡率分别为36.1%、63.9%和75.0%;2、3和4 d的LC50分别是7.98×106、4.27×106和8.02×105 cfu/mL。用浓度1×108 cfu/mL的菌悬液处理菜心叶片饲喂黄曲条跳甲成虫,12 d的校正死亡率为23.25%。用浓度1×105、1×107和1×109 cfu/m

    Rough rice grains are often stored for extended periods before they are used or consumed. However, during storage, the rough rice is vulnerable to insect infestation, resulting in significant economic loss. Previous studies have shown that volatiles cues, physical characteristics, and taste chemicals on the grains could be the important key behavior factors for storage insect pests to locate the hosts and select oviposition sites. It is also well known that the transgenic Bt rough rice line T1C-19, which expresses a cry1C(⁎) gene has a high resistance to Lepidoptera pests. However, there were no evidences to show the consequences of host preference for non-target insect pests after growing Bt transgenic rice. In this study, the potential key factors of Bt rough rice were investigated for their impacts on the behaviors of non-target pest lesser grain borer Rhyzopertha dominica, the main weevil pest of grain and its parasitic wasps Anisopteromalus calandrae, the natural enemy of the beetle. Both electronic nose and electronic tongue analyses showed that the parameters of Bt rough rice were analogous to those of the non-Bt rough rice. The volatile profiles of Bt and non-Bt rough rice examined by gas chromatographic mass spectrometry (GC-MS) were similar. For most volatile compounds, there were no significantly quantitative differences in compound quantities between Bt and non-Bt rough rice. The densities of sclereids and trichomes on the rough rice husk surface were statistically equal in Bt and non-Bt rough rice. The non-target pest, R. dominica, and its parasitoid wasp, A. calandrae, were attracted to both rough rice and could not distinguish the transgenic T1C-19 from the isogenic rough rice.

    为研究中华蜜蜂和Apis cerana cerana化学感受蛋白AcerCSP3在化学感受系统中的生理功能,本实验通过对AcerCSP3进行原核表达、分离纯化后,利用荧光法研究了体外重组AcerCSP3与1-NPN以及候选化学配基的结合特征.Scatchard方程显示AcerCSP3与1-NPN的解离常数KD为8.29 μmol/L,结合位点数约等于1.在候选配基竞争1-NPN与AcerCSP3结合的实验中,5种配基均能在200 μmol/L浓度下使1-NPN的相对荧光强度下降至50%以下.其中β-紫罗兰酮其至能使1-NPN的相对荧光强度下降至10%左右,表明候选配基均与AcerCSP3有较强的结合能力,而3,4-二甲基苯甲醛与中蜂AcerCSP3的结合能力最强,KD达到18.77 μmol/L.本研究所用化学配基均为植物花与叶片的挥发性的次生代谢产物,表明AcerCSP3可能作为中蜂化学感受系统的一部分,在其搜寻某些植物花粉蜜源时作为气味分子运载体发挥一定的作用.%In order to clarify the physiological function of AcerCSP3, a chemosensory protein (CSP) in Apis cerana cerana, the recombinant protein AcerCSP3 was successfully expressed in a optimized prokaryotic expression system, and the binding properties of the purified AcerCSP3 with 1-NPN was then investigated.Scatchard plot analysis indicated that the dissociation constant between 1-NPN and AcerCSP3 was 8.29 μmol/L and the binding site number was about one. In the competitive binding assays, all the five candidate ligands at the concentration of 200 μmol/L reduced the relative fluorescence intensity of 1-NPN by more than 50% , with β-ionone causing 90% reduction in the relative fluorescence intensity, suggesting that all the tested ligands have strong binding capability with AcerCSP3. 3, 4-Dimethylbenzaldehyde had the strongest binding capability with a dissociation constant as high as 18.77 μmol/L. All the candidate chemical ligands are plant volatile secondary metabolites, indicating that AcerCSP3 may act as a carier for

    The effects and changing patterns of UV-B on growth, development and reproduction of Sitobion avenae (Fabricius) were evaluated by establishing an age-specific life table of S. avenae exposed to UV-B for eight successive generations. The results revealed that the population degradation existed in the population of S. avenae after being raised for several generations in the experimental condition. Under the UV-B irradiation, the developmental duration (T) increased gradually with the increase of generations, while the intrinsic rate of increase (Rm) , net reproductive rate (R0) > finite increase rate (A) and population number tendency index (I) of S. avenae decreased until the third generations, then stable in the following generations. The developmental duration of the second, the third and the fourth instar nymph from F1 to F5 of S. avenae were delayed, while no significant difference was found in F7 generation. Additionally, under the condition of UV-B, the adult longevity, fecundity (F) and population number tendency index (I) decreased until the F3 generation and then increased or trended to stabilize thereafter. In conclusion, the effects of UV-B would be accumulated in the progeny. As the selective forces in the environment, UV-B inhibited the growth and propagation of S. avenae, however, the adaptation of S. avenae to stress was enhanced with the increase of generations. We also found that, the transform of phenotype from unwinged to winged S. avenae was significant in this study, which was related with that of the ecology parameters.%为评估紫外线UV-B对麦长管蚜Sitobion avenae (Fabricius)生长、发育和繁殖的影响,用中波紫外线(UV-B)连续照射8代麦长管蚜3、4龄若虫,并用特定年龄生命表方法对其后代生态学参数进行分析.结果显示,麦长管蚜在实验室条件下多代饲养,表现出明显的种群退化现象.在UV-B的影响下,随着世代的增加,麦长管蚜的内禀增长率(Rm)、净增值率(R0)

Numerous empirical studies have been unable to reject the hypothesis that return unpredictable and that stock price follows a random walk or martingale process. The essence of the mean-reversion hypothesis is that the stocks price contains a temporary component. Thus, the market value of stock deviates from the fundamental value but will revert to its mean. The objective of this study is to test the mean reversion hypothesis in Indonesian capital market, by investigate the size and significance of mean reversion component of stock prices at the Jakarta Stock Exchange, for the period of January 1990 through December 2003, and to investigate the size of the forecast error variance decomposition for real stock prices which is caused by permanent innovation and temporary innovation for a horizon of 2, 3, 4, 6, 12 and 24 months. By placing appropriate structural restrictions on a vector auto-regressive system estimated for the period of January 1990 through December 2003, it was found that the temporary component in the stock prices at the Jakarta Stock Exchange has significant size. From this, it can be inferred that the pattern of share price movements at the Jakarta Stock Exchange has a temporary component which will gradually disperse or undergo reverse mean.

The purpose of this study is to examine whether stock splits influence stock liquidity and return of an individual stock as well as in a group of stocks as a portfolio. Overall, the results of this study show that stock splits did influence stock price, trading volume and bid-ask spread but did not influence stock risk and abnormal return from the point of view of an individual stock as well as in a group of stocks as a portfolio. The test of a relationship between bid-ask spread and stock price, trading volume and stock risk for each stock shows that all three variable did not significantly affect the bid-ask spread.

    Over recent years a new approach to assessing company performance has been developed, known as Economic Value Added (EVA). EVA attemps to measure to value added produced by a firm by taking into cost of capital, where traditional measuring instrument has never been included. In the other hands, investors often use traditional financial ratios like ROA, ROE and EPS to measure share return. The problem identification is how EVA and financial ratios ROA, ROE and EPS influence to share return. ...

    Full Text Available During the period of March-April-May 2008 first time a sudden and unexpected jump in mortality in Broiler of 8 to 16 days of age was reported from broiler farms from Chitwan and Kathmandu valley in Nepal.Affected birds become recumbent, depressed and often go into a star-gazing spasm. Those signs included, huddling of the birds, trembling, blindness, loud chirping, litter eating, ataxia, comatose, birds dead with breast down and feet and legs straight out behind birds. Death within two to six hours after the onset of the symptoms Postmortem Lesions found with this syndrome include hemorrhages in the liver with necrosis of liver cells, regressed thymus, regression of the bursa of Fabricius, dehydration with the accumulation of kidney urates, fluid in the crop, fluid in the lower gut and watery contents of the ceca.Yellow elastic shanks swollen joints. Molted appearance of brain. . The mortality lasted for three to five days, after which, the mortality patterns return to a relatively normal level. When treated with liquid toxin binders like toxol,toxolivum,livertonic like hepatocare,naturaliv, immunomodulaters like immunocare,promin,pentasol and antibiotics there was check in mortality but the body weight recovery was not satisfactory only half as in comparison of in other illness. During this period laboratory culture of total 298 tissue specimen from dead bird was conducted which revealed growth of fungus spp like Aspergillus and Penicillium in 182 specimen while mixed E.coli and Staphylococcus were recovered in 68 specimen 24 specimen revealed the growth of Salmonella spp of bacteria and 24 samples were turn out to be negative while the attempt to isolate the Avian encephalomyelitis virus as it might be the cause suspected also turnout negative. On the basis of all laboratory findings and response to the treatment attempted finding of this preliminary investigation work is suggestive that the above syndrome indicates that mycosis emerging as

    coccidiose. The pullets were weighed and assigned to a complete randomized design with a 3 x 2 x 2 (three diets x two litter x two strains factorial arrangement, in a total of 12 treatments with six replications of 20 pullets. The experimental diets (D were: D1 = diet with commercial dose of antimicrobial; D2 = diet without antimicrobial; and D3 = diet without antimicrobial + 0.6% of DE. DE was composed by dehydrated yolk+albumen (55°C for 72 hours and showed negative result to Samonella spp. test. The use of recycled litter decreased pullet performance of two genetic groups, specially the Brown ones, that showed lower weights of spleen and bursa of Fabricius. This fact suggests better enlargement of lymphoid tissues, and that probably explains the smaller tolerance of White pullets to recycled litter. The antimicrobials minimize negative effect of recycled litter on pullet performance. Dehydrated egg is a good alternative to antimicrobials and can improve performance of pullets in the pre-starter on conventional environment.

    In recent years, subgroup J avian leukosis virus (ALV-J) has been found to frequently infect layers in China. This virus is responsible for economic losses due to both mortality and decreased performance in chickens. In this study, 45-d-old cloned free-range layers were suspected to be infected with ALV and other immunosuppressive diseases because their feathers were unkempt and their growth rate was impaired. To estimate the infection status and determine the source of ALV-J in the flock, 30 cloacal swabs were randomly collected to measure the p27 antigen level by enzyme-linked immunosorbent assay (ELISA). Among the birds that were tested, 87%(26/30) were positive. In addition, 6 anticoagulant blood samples were aseptically collected at random from the flock when the layers were 60 d old. These samples were centrifuged to obtain the leukocytes, which were then used to inoculate chicken embryo fibroblast (CEF) cells for the identification of ALV-J by indirect immunofluorescence (IFA). Of the samples tested, 100%(6/6) were positive. The flock’s production performance was also investigated, and 10 layers were necropsied to evaluate pathological changes at 115 d of age. The flock never laid eggs even though they reached the age of the first laying (110 d). Furthermore, there were pathological changes present, including atrophy of the thymus and bursa of Fabricius, undeveloped ovaries, glandular stomach haemorrhage, and hepatosplenomegaly. Paraffin-embedded sections of intumescent liver and spleen were prepared for antigen localisation using IFA. Positive signals were prevalent in paraffin-embedded sections of the intumescent liver and spleen. Furthermore, provirus DNA was extracted from 4 cloned free-range layers, and 2 paternal parents (HR native cocks), and the gp85 gene of ALV-J was amplified by PCR to analyse the genetic variation. The results of the autogenous variation analysis showed that the 6 strains were 98.5-99.7%homologous. This study indicated that

    From July to November 2012, preliminary coprological examinations were carried out on 85 pooled faecal samples of different aged ring-necked pheasants (Phasianus colchicus) (hatches from May until July) from an intensive artificial breeding programme in the Czech Republic. Cryptosporidium oocysts were detected in 12 samples (14.1 %) of ages >12 weeks (August-September). These results were supported by findings of Cryptosporidium baileyi and Cryptosporidium meleagridis oocysts in intestinal, or cloacal contents, and/or the bursa of Fabricius in 9 from 36 examined dead pheasants (prevalence 25 %). We describe in detail the various age groups of pheasants after hatching and present graphically the overall results of coprological examinations, showing pathways of infection of C. baileyi and C. meleagridis during the full rearing seasons of 2013 and 2014. We found very similar mean proportions of Cryptosporidium-positive samples over the entire 2013 period in pheasantry (173 pooled samples tested, 25 positive, 14.5 %) and 2014 (238 samples tested, 43 positive, 18.1 %). All tests were verified as being Cryptosporidium positive in 9 from 219 (prevalence 4.1 %) and 4 from 168 (prevalence 2.4 %) post-mortem examinations. Significantly, C. baileyi was found more frequently in faeces, with positivities ranging from 11.1 to 100 % (4->16-week-old pheasants). Oocysts of C. meleagridis were detected at ages 6->15 weeks ranging from 7.1 to 100 % in faeces during the rearing seasons. The burdens of C. baileyi (7 of 14 and 10 of 16) and C. meleagridis (5 of 14 and 7 of 16) for each year, in monitored brooder houses, flight pens and spread across all open areas were recorded. Oocysts of C. baileyi and C. meleagridis obtained from this study, and Cryptosporidium galli (obtained in another aviary from 36-week-old pheasants), were sequenced, and we characterized the highly variable 60-kDa glycoprotein gene of C. meleagridis. These results highlight the real risk of

    The development of antibiotic-resistant bacteria has led to a need for alternatives to antibiotics for growth promotion and disease prevention in poultry production. The helical polysaccharide beta-1,3/1,6-glucan is derived from the cell wall of Saccharomyces cervisiae and has immunomodulating activities. The objective of this study was to determine the ability of 2 supplementation programs with a commercial beta-1,3/1,6-glucan product to protect broiler chicks from experimental respiratory challenge with Escherichia coli. Chicks were housed in battery-brooders from 1 d of age and fed a standard starter diet or the same diet containing 20 g/ton (22 ppm) of purified beta-1,3/1,6-glucan either continuously (BG25d) or for only the first 7 d prior to challenge (BG7d). At d 7 one-half of the birds were inoculated in the thoracic air sac with 800 cfu of a serotype O2, nonmotile strain of E. coli. All surviving birds were necropsied at d 25. Body weight of survivors and feed conversion efficiency were protected from the adverse effects of E. coli challenge by BG7d but not by BG25d. Mortality was nominally decreased from 63% (control) to 53% in BG25d and 47% in BG7d, but these decreases were not significant. The relative weights of the liver and heart were increased, and the bursa of Fabricius relative weights were decreased by E. coli challenge, and these effects were modulated by beta-glucan treatment. Despite positive effects of BG7d in E. coli-challenged birds, the BW of nonchallenged birds was decreased by BG7d and BG25d. These results suggest that supplementation of broiler diets with beta-1,3/1,6-glucan may be valuable for decreasing production losses due to E. coli respiratory disease, but that the immune stimulation provided may also result in decreased production values under experimental battery conditions or for birds raised in an environment with minimal disease challenges.

    Selenoprotein has many functions in chicken, and the expression of selenoproteins is closely associated with the selenium (Se) level. However, little is known about the expression patterns of selenoproteins in chicken immune organs. Here, we investigated the effect of dietary Se deficiency on the expressions of 23 selenoproteins in broiler immune organs. In this study, 150 broilers were randomly divided into two groups (75 chickens per group). The chickens were maintained either on a diet supplemented with Se through the addition of 0.2 mg/kg of Se (C group) via sodium selenite or on a Se-deficient granulated diet (L group) until the broilers exhibited an onset of exudative diathesis (ED). Following euthanasia, the samples from the immune tissues (including the spleen, thymus, and bursa of Fabricius) were quickly collected, and the messenger RNA (mRNA) expression levels of 23 selenoproteins were examined by real-time quantitative PCR and analyzed using principal component analysis. The results showed that Se deficiency decreased the mRNA levels of 23 selenoproteins in the thymus, spleen, and bursa of the Fabricius tissues of broiler chickens. Furthermore, we found that among 23 selenoproteins, the mRNA levels of Dio1 in the thymus, Txnrd2 in the spleen, and Txnrd3 in the bursa of Fabricius decreased significantly (90.9 %, 83.3 %, and 96.8 %, respectively). In addition, the principal component analysis (PCA) results suggested that Se deficiency mainly influenced the expression of antioxidative selenoproteins, especially glutathione peroxidases (Gpxs), thioredoxin reductases (Txnrds), and iodothyronine deiodinases (Dios) in chicken immune organs. The results of this study are valuable for understanding the relevance of selenoprotein activity in vivo. PMID:26631053

  16. Hyperpigmentation Results in Aberrant Immune Development in Silky Fowl (Gallus gallus domesticus Brisson.

    Directory of Open Access Journals (Sweden)

    Deping Han

    Full Text Available The Silky Fowl (SF is known for its special phenotypes and atypical distribution of melanocytes among internal organs. Although the genes associated with melanocyte migration have been investigated substantially, there is little information on the postnatal distribution of melanocytes in inner organs and the effect of hyperpigmentation on the development of SF. Here, we analyzed melanocyte distribution in 26 tissues or organs on postnatal day 1 and weeks 2, 3, 4, 6, 10, and 23. Except for the liver, pancreas, pituitary gland, and adrenal gland, melanocytes were distributed throughout the body, primarily around blood vessels. Interaction between melanocytes and the tissue cells was observed, and melanin was transported by filopodia delivery through engulfed and internalized membrane-encapsulated melanosomes. SFs less than 10 weeks old have lower indices of spleen, thymus, and bursa of Fabricius than White Leghorns (WLs. The expression levels of interferon-γ and interlukin-4 genes in the spleen, and serum antibody levels against H5N1 and infectious bursal disease virus were lower in SF than in WL. We also found immune organ developmental difference between Black-boned and non-Black- boned chickens from SFs and WLs hybrid F2 population. However, degeneration of the thymus and bursa of Fabricius occurred later in SF than in WL after sexual maturity. Analysis of apoptotic cells and apoptosis-associated Bax and Bcl-2 proteins indicated that apoptosis is involved in degeneration of the thymus and bursa of Fabricius. Therefore, these results suggest that hyperpigmentation in SF may have a close relationship with immune development in SF, which can provide an important animal model to investigate the roles of melanocyte.

    The European Commission Recommendation 2006/576/EC indicates that the maximum tolerable level of ochratoxin A (OTA) in poultry feeds is 0.1 mg OTA/kg. Thirty-six 1-day-old male broiler chicks were divided into two groups, a control (basal diet) and an OTA (basal diet + 0.1 mg OTA/kg) group. The OTA concentration was quantified in serum, liver, kidney, breast and thigh samples. The thiobarbituric acid reactive substances (TBARS) content were evaluated in the liver, kidney, breast and thigh samples. The glutathione (GSH) content, and catalase (CAT) and superoxide dismutase (SOD) activity were measured in the liver and kidney samples. Histopathological traits were evaluated for the spleen, bursa of Fabricius and liver samples. Moreover, the chemical composition of the meat was analysed in breast and thigh samples. In the OTA diet-fed animals, a serum OTA concentration of 1.15 ± 0.35 ng/ml was found, and OTA was also detected in kidney and liver at 3.58 ± 0.85 ng OTA/g f.w. and 1.92 ± 0.21 ng OTA/g f.w., respectively. The TBARS content was higher in the kidney of the ochratoxin A group (1.53 ± 0.18 nmol/mg protein vs. 0.91 ± 0.25 nmol/mg protein). Feeding OTA at 0.1 mg OTA/kg also resulted in degenerative lesions in the spleen, bursa of Fabricius and liver. The maximum tolerable level of 0.1 mg OTA/kg, established for poultry feeds by the EU, represents a safe limit for the final consumer, because no OTA residues were found in breast and thigh meat. Even though no clinical signs were noticed in the birds fed the OTA-contaminated diet, moderate histological lesions were observed in the liver, spleen and bursa of Fabricius.

The results showed that different volumes of blood mealswould be consumed by the same progeny of Am. variegatum female ticks leading todifferent engorged weights. The study revealed that in Am. variegatum egg masscould account for as high as 51% of the engorged body weight. The female tickcould also oviposit as high as 31,487 eggs and also as low as 2421 eggs in samestudy cohorts. The study also showed that the actual engorged weight might notreflect the actual ovipositing capacity of the tick. Only the weight of the eggmass laid determined the actual quantity of eggs.

    Full Text Available Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or to additional food source, process referred as postfeeding larval dispersal. Some of the most important aspects of this process were investigated in Chrysomya megacephala, utilizing a circular arena to permit the radial dispersion of larvae from the center. To determinate the localization of each pupa, the arena was split in 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the larvae that disperse farther are those with higher weights. The majority of individuals reached the depth of burying for pupation between 7 and 18 cm. The study of this process of dispersion can be utilized in the estimation of postmortem interval (PMI for human corpses in medico-criminal investigations.

    Objective:To explore the relationship between shoulder pain and inflammatory reaction in the subacromial bursa tissues in patients with rotator cuff injury or traumatic shoulder joint anterior instability.Methods:Twenty-five patients with rotator cuff injury(rotator cuff injury group)and 21 patients with traumatic shoulder joint anterior instability(shoulder joint instability group)were selected and treated with surgery.The degree of shoulder pain of all patients were evaluated by using the visual analogue score(VAS)before the surgery.The subacromial bursa tissues were fetched out during the surgery,and the level of tumor necrosis factor -α(TNF -α)and interleukin -1β(IL-1β)were measured by using enzyme linked immunosorbent assay.The VAS scores of shoulder pain and the level of TNF -αand IL -1βin subacromial bursa tissues were compared between the 2 groups respectively,and correlation analysis were applied to study the relationship between the VAS scores of shoulder pain and the level of TNF -αand IL -1βin subacromial bursa tissues in the 46 patients.Results:The VAS scores of shoulder pain and the level of TNF -αand IL -1βin subacromial bursa tissues of rotator cuff injury group were higher than those of shoulder joint instability group(7.07 +/-1.06 vs 5.03 +/-0.74 points,t =7.648,P =0.003;189.61 +/-40.46 vs 115.91 +/-17.32 pg/100mg,t =8.252,P =0.000;4.40 +/-0.88 vs 2.67 +/-0.62 pg/100mg,t =7.561,P =0.000).The results of correlation analysis showed that the VAS scores of shoulder pain were positively correlated with the level of TNF -αand IL -1βin subacromial bursa tissues(r =0.952,P =0.000;r =0.945,P =0.000).Conclusion:The inflammatory reaction in the subacromial bursa tissues is the impor-tant cause of shoulder pain in patients with rotator cuff injury and patients with traumatic shoulder joint anterior instability.The inflammatory reaction of subacromial bursa tissues is more significant in patients with rotator cuff injury compared to patients with

    The experiment was conducted to determine the effects of early feed-restriction on slaughter production and index of immune organs. 250 ROSS 308 broiler chickens were randomly allocated to ten groups divided by orthogonal L9(34) experiment including three factors each for three levels, starting time (5,7 and 10 days of age), duration (7,10 and 14 days) and, intensity (90%, 80% and 70%) of feed restriction. Slaughter production of restriction showed a sequence of duration>intensity>starting time. With the longer of duration and the stronger of intensity, there was a significant decrease of the weight of body, carcass, whole eviscerated, breast and leg. The index of spleen of 23 days about the three feed-restriction factors was all lower, and the index of 42 days all higher than the control group. The index of thymus of broilers of 23 days in feed-restriction groups was all lower and the index of bursa of fabricius of 42 days was also lower than the control group. Thyroxine T3 and growth hormone of feed-restriction broilers of group 1 and 3 at 23 and 42 days were both lower than the control group, while the ratio of T4/T3 was all higher than the control group. The broilers, feed-restricted at 5 days for 90% and 7 days, had a higher slaughter production than the control group, while the broilers restricted at 5 days for 70% and 14 days was stunned and did not have a compensatory growt
