  1. Expression of the ephrin receptor B2 in the embryonic chicken bursa of Fabricius

    Science.gov (United States)

    Chicken B-cells develop in a specific organ, the bursa of Fabricius. To understand the bursal microenvironment guiding B-cell development, previous studies identified ephrin (Eph) receptor B2 (EphB2) gene transcripts in the embryonic bursa. We hypothesize that the EphB2 receptors and their ligands r...

  2. Vitamin E as a radioprotector of bursa of Fabricius in chicks

    International Nuclear Information System (INIS)

    Radioprotective influence of vitamin E has been studied on the bursa of Fabricius 1 and 7 day old white leghorn chicks exposed to 2.25 Gy whole body γ-radiations. The study has revealed that the loss of lymphocytic population in the bursal follicles due to irradiation was very small in vitamin E treated animals compared to the untreated irradiated chicks. Also, the rate of reparation and lymphocytic repopulation was enhanced with vitamin E administration. (author). 8 refs., 8 figs

    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

  4. Apoptosis in the chicken bursa of fabricius induced by X-irradiation

    International Nuclear Information System (INIS)

    Immature B lymphocytes in the chicken bursa of Fabricius have previously been reported to undergo apoptosis by low doses of ionizing radiation. In the present study, newly hatched chickens were subjected to whole-body X-irradiation, and the bursa of Fabricius was examined at various postirradiation times by light and electron microscopy to obtain information on the change of ultrastructure of irradiated bursal cells as well as on the time course and dose-response for the induction of apoptosis. Histological examination by light microscopy showed that pyknotic cells started to increase in the bursa within a few hours after irradiation and the frequency of occurrence reached a maximum at 6 hr. An evident increase of the pyknotic cells in number was observed at a dose of as little as 1 Gy, and the frequency increased with increases in the dose, reaching over 90% Gy. Electron microscopy of the irradiated bursa revealed typical apoptotic morphology such as chromatin condensation, nuclear fragmentation, formation of apoptotic bodies and phagocytosis of pyknotic cells. Induction of apoptosis was also confirmed by the appearance of a typical DNA ladder pattern on agarose gel. Thus, the present results demonstrate that the chicken bursal cells are hypersensitive to X-irradiation with regard to induction of apoptosis, and that the apoptotic bursal cells exhibit most of the ultrastructural features known to be typical of apoptosis

As many as 45 embryo chicken eggs at nine day old were used inthis research, then grouped into three groups of 15 embryos chicken eggs each, these were: Embryo chickeneggs without vaccination (Group I, vaccinated with IBD intermediate plus commercial vaccine (Group IIand IBD intermediate plus local vaccine (Group III. Vaccinations were done at 14 days old. All groups thenterminated each three embryos at 12 hours, 1, 2, 3 days post vaccination. The results showed that pathologicanatomic lesions could not be detected. Whereas pathologic lesions were detected in the group that werevaccinated with intermediate plus local IBD observed more severe than in the group that vaccinated withintermediate plus commercial IBD. Lesions such as edema, hemorrhages, necrosis of lymphoid cells wereobserved microscopically in embryo at 12 hours, 1, 2 and 3 days post vaccination in Group II and group III.The lesions were more severe at two days post vaccination causing some lymphoid follicles disappeared at three days post vaccination. However, they were not detected again in the bursa Fabricius three days afterhatching. Cells containing antigens of gumboro were detected in the bursa Fabricius of chicken embryo atone day until three days post vaccination, then disappeared after three days post hatch. It was concludedthat pathologic description of bursa fabricius showed that virus vaccines used for vaccinated IBD in ovowere still virulent, that can cause histopathologic lesions. The viruses are suggested to be more attenuatedbefore using as vaccine in ovo.

    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.

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.

    Infections of young chickens with infectious bursal disease virus (IBDV) result in depletion of lymphoid cells of the bursa of Fabricius (BF) due to necrosis and apoptotic processes. Interactions between IBDV and lymphoid cells were investigated by labelling paraffin-embedded tissue sections of infected BF with combinations of either immunohistochemistry (IHC), in situ hybridization (ISH) or in situ TUNEL reaction (IST). With regard to specificity and sensitivity, results of ISH were comparable to those of IHC. By double-labelling it was shown, for the first time, that viral antigen was present in most of the apoptotic cells. This suggests that IBDV may be directly involved in the induction of the apoptotic process. However, some cells also showed either viral antigen or DNA fragmentation, especially at the early stages of infection. It should be taken into account, therefore, that the apoptotic processes might also be induced by IBDV through indirect interaction between cells. Remarkably, in some of the infected lymphoid cells ISH signals were observed in the nucleolus. PMID:26915384

    International Nuclear Information System (INIS)

    The ability of the bursa of Fabricius to regenerate after gamma-irradiation and bone marrow reconstitution was examined in chickens thymectomized (TX) immediately after hatching. Irradiation (2 X 500 R) 3 weeks after hatching was followed by impaired bursa regeneration, as judged both by bursa/body weight ratios and by bursa follicle development 3-6 weeks later in TX as compared to control birds. Germinal center formation in the spleen was deficient, and immune responses to sheep erythrocytes (SRBC) and B. abortus (BA) were moderately reduced in the TX as compared to control birds irradiated at 3 weeks but not in TX birds irradiated at 5 weeks of age

    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

    International Nuclear Information System (INIS)

    Introduction: Since fluid filled bursae lead to visible structures on MR images it is important to establish criteria to recognize them and to differentiate them from tumorous fluid-like structures. With this study the bursae around the knee joint were analyzed for potential differential diagnostic criteria such as localisation, size and shape. Material and methods: In a retrospective study of 133 MR exams the frequency, localization and morphology were registered. The frequency of occurrence was correlated with the frequency of an effusion by means of the chi2 test. Results: The most frequently recognized bursae were bursa subtendinea musculi gastrocnernii medialis (54.9%), bursa musculi semimembranosi (21%), and bursa infrapatellaris profunda (18.8%). 8 different bursae were identified in complete. Size ranged from 2 to 18 mm. The shape was round and ovoid. The bursa subtendinea musculi gastrocnemii medialis and bursa musculi semimembranosi correlated with the occurrence of an effusion. Conclusion: Bursae around the knee are frequently visualized as asymptomatic fluid like structures. Knowledge of the typical localization, size and contour is important for identification and differentiation diagnosis against ganglia, cysts or joint recesses. (orig.)

    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.

    Cysts and bursae of the nasopharynx are uncommon and seldom symptomatic when compared with malignant tumors of this region. However, it is noteworthy that in the presence of symptoms, a good knowledge of their radiological appearance is useful to establish the correct diagnosis. Cysts of Rathke's pouch, pharyngeal bursa of Luschka, Tornwaldt's cysts, retentional cysts of the seromucinous glands, oncocytic cysts, intra-adenoid cysts, branchial cysts, prevertebral or retropharyngeal abscess and pseudocysts of the nasopharynx will be discussed in this paper.

  5. Bilateral lipoma arborescens of the subdeltoid bursa

    International Nuclear Information System (INIS)

    Lipoma arborescens is a rare cause of chronic monoarticular arthritis. It is most commonly seen in the knees, but only a few cases involving other joints, especially the subdeltoid bursa, have been described. To our knowledge, this is the first reported case of lipoma arborescens involving bilateral subdeltoid bursae. Although it is associated with joint effusion, synovial cysts and erosions, the presence of reactive bone formation has not been reported. Magnetic resonance imaging is a very effective method for the diagnosis of this rare condition because of its ability to do tissue characterization

    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.)

    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.

  20. A radiographic study of the distal interphalangeal joint and navicular bursa of the horse

    International Nuclear Information System (INIS)

    Radiographic contrast studies were used in 50 forelimbs from 13 live horses and 12 fresh adult cadavers to determine the frequency of communication between the navicular bursa and the distal interphalangeal joint. Injections of contrast medium were made into the dorsal aspect of the distal interphalangeal joint of one limb and into the navicular bursa of the other forelimb of each horse. In 25 limbs in which contrast medium was injected into the distal interphalangeal joint, no communication was demonstrated between the joint and the navicular bursa. In 20 of the 25 limbs in which injection was made into the navicular bursa, no communication between joint and bursa was seen. In five horses, contrast medium was visible in both the distal interphalangeal joint and the navicular bursa. However, in four of five horses the communication was clearly iatrogenic. In both limbs of one horse, contrast medium was seen to enter the digital flexor tendon sheath after injection into the navicular bursa.There is probably no naturally occurring communication between the navicular bursa and distal interphalangeal joint in the horse

    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

  7. Potential of bursa-immigrated hematopoietic precursor cells to differentiate to functional B and T cells

    International Nuclear Information System (INIS)

    The potential of hematopoietic precursor cells, recently immigrated into the 13- and 14-day-old embryonic bursa, to migrate to the thymus and to differentiate to functional T cells was investigated. Chromosomally marked cell populations obtained from 13- and 14-day-old embryonic bursas were transferred i.v. to 780 R γ-irradiated chick embryos of equivalent age. When appropriate chimeras were examined at 4 to 12 weeks after cell transfer, donor cells were found to proliferate primarily in the bursa. Significant donor cell influx into the thymus was not detected. In correlation with these findings, Con A- and PHA-responsive T cells in thymus and spleen cell cultures of recipients remained of host origin whereas the number of anti-CIg responsive B cells of donor type increased gradually in the spleens of recipients. An initial lag period preceded the accumulation of functional donor B cells in the spleens of recipients, despite the predominant presence of dividing donor cells in the bursa. This suggests that the transferred bursal cell population required substantially longer to mature and emigrate from the bursa as functional B cells than the host cell population remaining in the irradiated bursas at time of cell transfer. The failure to detect significant influx of donor cells into the thymus and their failure to differentiate to functional T cells suggest that the recently bursa-immigrated hematopoietic stem cells of 13- and 14-day-old embryos may not be pluripotential cells, but rather cells already committed to the B cell line of differentiation

    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.)

  15. Dynamic enhanced MRI of the subacromial bursa: correlation with arthroscopic and histological findings

    International Nuclear Information System (INIS)

    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. Dynamic MRI appears to correlate with inflammatory activity of synovium of the subacromial

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. Dynamic MRI appears to correlate with inflammatory activity of synovium of the subacromial

    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.

    Sonography is suitable to recognize fluids in the suprapatellar bursa, which can represent an indirect sign of intra-articular knee effusion. In order to obtain the physiologic parameters of suprapatellar bursa, 50 healthy volunteers, 38 sedentary and 12 sportsmen, were evaluated by means of US. The bursa was recognizable in 8/50 cases (16%) with quadriceps in prolapse (mean thickness: 1.8 mm, mean length: 20.5 mm), and in 23/50 cases (46%) with quadriceps in contraction (mean thickness: 2.6 mm, mean length: 22.6 mm). Suprapatellar bursal thickness ranged 1-4 mm, and its length ranged 12-44 mm. The suprapatellar bursa appeared as a well-defined hypoechoic band, cranial to patella, anterior to the distal femoral shaft, and posterior to quadriceps tendon. Quadriceps contraction increases both thickness and length of bursal swelling (1 and 2 mm, respectively, on the average). When sportsmen were compared with sedentary subjects, suprapatellar bursa diameters were observed not to change, but the bursal itself was evident in 3/12 (25%) and in 8/12 (66%) of cases, according to whether the quadriceps was in prolapse or in contraction. Bursal contents were homogeneously anechoic and bursal outline smooth and regular in all cases (23/23). Bursal morphology was symmetric, in 23/23 cases, in length, regularity of outline, and echogenicity of contents. Thickness alone resulted asymmetrical in 2/23 subjects (8%), even though variations were less than or equal to 2 mm. In conclusion, we can consider as pathologic features: thickness greater than 3-4 mm, asymmetry greater than 2 mm, irregular outline, and inhomogeneous contents. These parameters must be examined in pathologic subjects and further research is mandatory. PMID:1557543

  2. Effect of electronic beam irradiation on last instar larvae of lasioderma serricorne fabricius

    International Nuclear Information System (INIS)

    The electronic beam irradiation effects on the last instar larvae of cigarette beetle (Lasioderma serricorne Fabricius) in tobacco were studied, and the mortality in 42 days, lethal time, pupation rate, emergence rate and reproductive capacity after irradiation were measured. The results showed that the mortality increased with the increase of irradiation dosage, but the larvae did not dead immediately. The last instar larvae irradiated by the dosages higher than 480 Gy could prevent the development of larvae to adults. No new generation was found after 300 Gy treatment of the last instar larvae. So 300 Gy irradiation could be considered as a suitable dose to prevent the reproduction of cigarette beetle of the last instar larvae in the tobacco. (authors)

    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.

    Artificial diets prepared with wheat germ, soybean protein, dextrosol, potato starch, sucrose, cellulose, soybean or sunflower oil, and vitamin solution for rearing Nezara viridula (L.) and Euschistus heros (Fabricius) were tested under controlled temperature (25 {+-} 1 deg C), RH (60 {+-} 10%), and photophase (14h). Three diets were tested and compared with the natural diet privet [soybean and peanut seeds and privet Ligustrum lucidum Ait. fruit (Oleaceae)]. All three artificial diets allowed full development. The diet containing sunflower oil was the most suitable for N. viridula while E. heros developed better on a diet composed of soybean oil. Data indicated that the artificial diets were inferior to the natural diet. The artificial diets were more adequate for E. heros. (author)

    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.

    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. - Highlights: ► Lesions typical for adenovirus infection detected in cloacal bursa of dead gulls. ► Confirmation of adenovirus infection by electron microscopy and deep sequencing. ► Sequence analysis indicates that it is a novel adenovirus in the genus Aviadenovirus. ► The novel (Gull) adenovirus was detected in multiple organs of two species of gulls.

    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.

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.

    Full Text Available In the rapidly globalizing world health tourism has gained momentum as exports from the place of origin. Since 2002, our country launched the “Health Transformation Program” reaching the fast, quality and efficient health service levels in developed countries. Compared to the United States and European countries, more cost-effective provision of quality services has provided our country with advantages. Turkey has now started working on receiving a deserved share in the world health tourism market. Turkey has established a health tourism policy as in many countries that have achieved success in the health tourism. Due to awareness of stakeholders in all sectors, mainly in all relevant ministries, health care providers, travel agencies, accommodation facilities and intermediaries, there has been an increase in patient flow for planned treatment. At this point, activities have started with all stakeholders of the city by showing the city’s position in the health tourism with thermal and medical potential and its expert human resources possessed by the historical thermal city of Bursa. The importance of the contribution of the tourism sector to the national economy in terms of Bursa is increasing every day. Bursa, which tries to combine its natural and cultural wealth with service of high quality, in the future will be the city receiving more health tourists. In order to achieve this, development of health tourism service areas, definition of potential by analyzing current situation and development of strategies based on these determinations are important in terms of defining the target destinations.

  3. Radiolabelling of Chrysomya megacephala (Fabricius, 1794) (Diptera, Calliphoridae) and rearing of Belonuchus rufipennis (Fabricius, 1801) (Coleoptera, Staphylinidae) on eggs of this fly

    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

    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.

    Full Text Available BACKGROUND: Chrysomya megacephala (Fabricius, a prevalent necrophagous blowfly that is easily mass reared, is noted for being a mechanical vector of pathogenic microorganisms, a pollinator of numerous crops, and a resource insect in forensic investigation in the postmortem interval. 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.

    This paper studies the Ornstein-Uhlenbeck model that incorporates long memory stochastic volatility which is known as fractional Ornstein-Uhlenbeck model. The determination of the existence of long range dependence of the index prices of FTSE Bursa Malaysia KLCI is measured by the Hurst exponent. The empirical distribution of unobserved volatility is estimated using the particle filtering method. The performance between fractional Ornstein -Uhlenbeck and standard Ornstein -Uhlenbeck process had been compared. The mean square errors of the fractional Ornstein-Uhlenbeck model indicated that the model describes index prices better than the standard Ornstein-Uhlenbeck process.

    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.

    Mansor, Nur Jariah; Jaffar, Maheran Mohd

    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 Defensive behavior associated with secretions from the prosternal paired glands of the larvae of Heliconius erato phyllis Fabricius (Lepidoptera, Nymphalidae. Our work presents for the first time, the defensive behavior associated with the release of the product of the prosternal paired glands of the larva of Heliconius erato phyllis Fabricius, 1775 (Lepidoptera, Nymphalidae, Heliconiinae. The prosternal glands were first described for larvae of H. erato phyllis. They are formed by two types of glandular structures: the impair gland and the paired glands. The prosternal glands are located within the conical integumentary sac, which in turn is situated on the individual's prosternum. The main goal of this study is to analyze the existence of any secretion from the prosternal paired glands, and check the action mode of this secretion. The methodology used for chemical analysis of the glands included the aeration and, analysis in gas chromatography and gas chromatography-mass spectrometry. The results show that the prosternal glands do not produce volatiles. Bioassays were conducted with simulated and natural attacks and revealed that the prosternal paired glands produce secretions of defense together with silk produced by labials glands as a defense strategy, described for the first time, against ants. The strategy consists in wrapping the ant with silk threads, the entire wrapped object moved to the end of the body, with the aid of the legs and prolegs, and possibly fixed in a nearby place. Evidence for the existence of a conical integumentary sac in larvae of other species and families of Lepidoptera allows us to propose the possibility of occurrence of prosternal paired glands with defensive function in these other groups as well.

    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).

  9. Puncture wounds into the navicular bursa of the horse: role of radiographic evaluation

    International Nuclear Information System (INIS)

    Radiography was used to evaluate 32 horses presented for puncture wounds into the navicular bursa. At the initial radiographic examination, 21 horses had no radiographic signs of osteomyelitis, while 11 did. The mean-time interval between injury and radiographic examination was 20.6 days for horses without evidence of osteomyelitis and 59.3 days for those with evidence of osteomyelitis. Radiographic signs of osteomyelitis of the navicular bone included flexor cortical destruction and irregularity of the flexor surface. Other abnormalities included pathologic fracture of the navicular bone, subluxation of the distal interphalangeal joint, or secondary joint disease. The lateromedial and palmaroproximal-palmarodistal oblique projections were most useful for identifying abnormalities of the navicular bone. There was a high correlation between horses that had positive presurgical radiographic signs and surgical findings. However, approximately 50% of horses that had negative radiographic findings initially had positive surgical findings. Ten of 21 horses with negative radiographic findings on initial examination had evidence of bony lesions when reevaluated from 3 weeks to 6 years later. Nine of 11 horses with radiographic signs of osteomyelitis on initial radiographic examination were euthanatized or had an unsatisfactory outcome. Seven of 10 horses with radiographic signs on reexamination were euthanatized. Thirteen of 20 horses with positive surgical findings for navicular bone infection were euthanatized or had an unsatisfactory outcome

    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.

    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.

    Shepherd's purse (Capsella bursa-pastoris), native to Europe, is commonly consumed fresh and sometimes inadequately washed before consumption in Korea. The objective of this study was to characterize isolates of spore-forming bacilli (SFB) in samples of fresh Shepherd's purse. Three genera were identified: Bacillus (9 species), Paenibacillus (3 species), and Brevibacillus (1 species). None of the genes of the hemolysin BL (HBL) and nonhemolytic enterotoxin (NHE) complexes, or of the emetic toxin, was detected in the 25 SFB isolates, except for 2 Bacillus pseudomycoides isolates, where all 3 genes of the HBL enterotoxin complex were detected. There were significant sequence variations between the 2 species (Bacillus cereus and B. pseudomycoides) in the 3 genes of the HBL enterotoxin complex. These findings may provide insights into the diverse characteristics of the B. pseudomycoides HBL enterotoxin complex. Antibiotic resistance was assessed using 8 antibiotics. Among the 25 SFB isolates, 11 showed resistance to antibiotics, of which 5 were multiresistant. Assessment of the spoilage potential showed that all 25 SFB isolates could produce enzymes that can cause spoilage of foods. In conclusion, our findings may serve as integrative information for food research and industrial sectors. PMID:26822957

  15. Evaluation of radon concentration in well and tap waters in Bursa (Turkey)

    International Nuclear Information System (INIS)

    222Rn measurements in water samples collected from 27 wells and 19 taps that were supplied from the investigated wells were conducted using the AlphaGUARD PQ 2000PRO radon gas analyser at sites across several geologic formations within the city of Bursa (Turkey). The measured radon concentrations ranged from 1.46 to 53.64 Bq l-1 for well water and from 0.91 to 12.58 Bq l-1 for tap water. Of the 27 sites sampled, only 7 had radon levels above the safe limit of 11.1 Bq l-1 recommended by the USEPA. In general, all determined concentrations were well below the 100 Bq l-1 revised reference level proposed by the European Union. These values of radon concentrations in water samples are compared with those reported from other countries. Doses resulting from the consumption of these waters were calculated. The minimum and the maximum annual mean effective doses due to 222Rn intake through water consumption were 0.02 μSv a-1 and 1.11 μSv a-1, respectively. (authors)

    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)

    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.

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.

To evaluate the involvement of the bursa located next to the head of the 5th metatarsal bone in patients with psoriatic arthritis (PsA in comparison with the other seronegative spondyloarthritis (SpA. Methods. All patients with PsA seen during a period of 24 months were enrolled. The control group included healthy subjects and patients with the other SpA. All subjects underwent clinical and ultrasound (US examination of the lateral surface of the 5th metatarsal. Results. 150 PsA patients (88 M; 62 F, 172 SpA (107 M; 65 F, and 95 healthy controls (58 M; 37 F were evaluated. Based on clinical and US evaluation, bursitis was diagnosed in 17/150 (11.3% PsA patients but in none of the SpA (P<0.0001 and healthy (P=0.0002 controls. In detecting bursitis, US was more sensitive than clinical examination, although the difference did not reach statistical significance (P=0.09. Conclusion. The bursa of the 5th metatarsophalangeal joint appears to be involved in PsA more frequently than by chance. If confirmed by other studies, this finding could be considered as a distinctive clinical sign of PsA, useful for differential diagnosis with the other SpA. In asymptomatic patients, US proved to be more sensitive in the detection of bursitis.

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.

    Nickel is an environmental pollutant that adversely affects the male reproductive system. In the present study, the effects of nickel exposure on Spodoptera litura Fabricius were investigated by feeding larvae artificial diets containing different doses of nickel for three generations. Damage to testes and effects on male reproduction were examined. The amount of nickel that accumulated in the testes of newly emerged males increased as the nickel dose in the diet increased during a single generation. Nickel exposure increased the amount of thiobarbituric acid reactive substances and decreased the amount of glutathione in treatment groups compared with the control. The activity levels of the antioxidant response indices superoxide dismutases, catalase, and glutathione peroxidase in the testes showed variable dose-dependent relationships with nickel doses and duration of exposure. Nickel doses also disrupted the development of the testes by decreasing the weight and volume of testes and the number of eupyrene and apyrene sperm bundles in treatment groups compared with the control. When the nickel-treated males mated with normal females, fecundity was inhibited by the higher nickel doses in all three generations, but fecundity significantly increased during the second generation, which received 5 mg kg(-1) nickel. Hatching rates in all treatments significantly decreased in a dose-dependent manner in the three successive generations. The effects of nickel on these parameters correlated with the duration of nickel exposure. Results indicate assays of testes may be a novel and efficient means of evaluating the effects of heavy metals on phytophagous insects in an agricultural environment. PMID:26807937

    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.

Likewise, the ammonia was higher in control tanks (0.19 mg/litre rather than experimental tanks (0.15mg/litre. The survival rate of different larval stages (nauplii, zoea and mysis were maximum in the present study than that of control tanks. The final survival rate of the post larvae from the control and experimental tank was 70 and 30% respectively. The average length of all post larvae was maximum when reared in experimental tank than control tanks. The general conclusion obtained from the present study is that the probiotics plays a vital role in maintaining water quality parameters throughout the larval cycle. It is clear from the microbial load data that vibrio sp. is dominant in the control tanks than in experimental tanks.

  14. Estimation of the adult male population of sweet potato weevil, Cylas formicarius (Fabricius) at its low-density period on Kikai Island in Japan

    International Nuclear Information System (INIS)

    The sweet potato weevil, Cylas formicarius (Fabricius) is a major insect pest of the sweet potato, Ipomoea batatas (L.) Lam. throughout the tropical and subtropical regions of the world. We estimated the entire adult male population of C. formicarius at its low-density period on Kikai Island, Kagoshima Pref., Japan. The population of adult males at the high-density period in September was about 5 times larger than that at its low-density period in May, both of which were estimated by Yamamura's method. Using this calculation in combination with an estimate of the maximal population size (4 x 10E6) by Sugimoto et al. in 1994, the total number of male weevils at their low-density period can be assumed to be less than 8 x 10E5

    While resistance against many other classes of acaricides has been described, products containing benzoylphenyl urea are currently still successfully used against the pesticide-resistant blue tick (Boophilus decoloratus) in South Africa. In order to assess any adverse impact of these tickicides on the important dung beetle (Coleoptera: Scarabaeidae) fauna, a bioassay was undertaken on the ecotoxicological effects of a fluazuron (benzoylphenyl urea) pour-on formulation (Acatak) on the survival and reproduction of the African dung beetles species Onthophagus gazella (Fabricius). The experiment yielded no significant differences in adult or larval survival, egg production, fecundity and fertility between the control and treatment group following three beetle generations over. These results suggested that treatment of cattle with the fluazuron pour-on formulation Acatak was not detrimental to the selected dung beetle species in any notable way. PMID:16978786

    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.

    Full Text Available We evaluated the prevalence, mean intensity and relative density of ticks in 467 wild birds of 67 species (12 families from forest and cerrado habitats at two protected areas of Minas Gerais, between March and September 1997. Ticks collected (n=177 were identified as larvae and nymphs of Amblyomma cajennense and four other species of Amblyomma. We report for the first time 28 bird species as hosts of the immature stages of A. cajennense, demonstrating the lack of host specificity of the larvae and nymphs. A. cajennense had 15% prevalence on birds, with a mean infestation intensity of 0.37 ticks per host sampled, and 2.5 ticks per infested bird. Prevalence varied in relation to host species, diet and between birds from forests at two successional stages. There were no differences in relation to host forest dependence, participation in mixed flocks of birds, and nest type constructed. A. cajennense is a species of medical and veterinary importance, occurring on domestic animals but is known little of its occurrence on wildlife.

  2. 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.

  4. X-ray induced sterility in adults of Dysdercus koenigii Fabricius

    International Nuclear Information System (INIS)

    Irradiation of late 1st instar nymphs of Dysdercus koenigii F. with X-ray dose of 10 to 50 Gy adversely affected their moulting and metamorphosis. Doses above 20 Gy completely inhibited nymphal development. At 20 Gy dose only 15 percent nymphs could reach adults stage with about 3-5 days delay. But at 10 Gy dose, 75 percent nymphs could metamorphose to adult stage as compared to 86 percent in control. Adults emerged in 10 Gy dose treatment were outcrossed to normal partners of opposite sex and also intercrossed to assess level of sterility induced in these insects. Fecundity was not affected in any of the four combinations tested. Almost complete sterility was induced in males whereas in females partial sterility was observed. Sterility was mainly due to induction of dominant lethal mutations. In case of treated females mated to normal males there was gradual recovery in fertility when successive egg batches of individual females were considered. However, no such recovery was found in males which emerged from irradiated nymphs. (author). 10 refs., 2 tabs

    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.

  7. 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

    Full Text Available In this paper, two methods for assessing the degree of melanization of pupal exuviae from the butterfly Heliconius erato phyllis , Fabricius 1775 (Lepidoptera, Nymphalidae, Heliconiini are compared. 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.

    2015-02-01

    Full Text Available There has been transformation of the food retail sector in the last 20 years, accompanied by multi-nationalization of the supermarket sector itself. Modern supply chains comprise the production and trade of high-value produce, usually destined for export to high-income markets or for supermarket retail. Two striking changes in the retail food sector have been the movement of supermarket chains towards specialized wholesalers in the organization of their procurement systems, and the emergence of strict quality and safety standards. Debates on the supermarket revolution and its impact on small farmers continue in the literature. Some writers suggest that small farmers are excluded from modern supply chains because they cannot meet supermarkets’ requirements. However, some writers imply that small farmers are not under threat. In this context, this paper aimed to examine the relationship between buyer and supplier, and reveal the structural and behavioural stresses of the modern supply chain in the context of the pear supply chain in Bursa (Gürsu. There are two research questions: 1 Are small farmers excluded from modern supply chains? 2 Are there differences between farmers in modern and traditional supply chains? The study concluded that there is a dual structure at work, in which traditional and modern supply chains intertwine and operate side by side. The study also found that small farmers are not excluded from the modern supply chain, and that there are no differences between farmers in modern and traditional supply chains.

    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

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 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.

    Among the options to control Alabama argillacea (Hübner, 1818) and Heliothis virescens (Fabricius, 1781) on cotton, insecticide spraying and biological control have been extensively used. The GM'Bt' cotton has been introduced as an extremely viable alternative, but it is yet not known how transgenic plants affect populations of organisms that are interrelated in an agroecosystem. For this reason, it is important to know how the spatial arrangement of pests and beneficial insect are affected, which may call for changes in the methods used for sampling these species. This study was conducted with the goal to investigate the pattern of spatial distribution of eggs of A. argillacea and H. virescens in DeltaOpal™ (non-Bt) and DP90B™ Bt cotton cultivars. Data were collected during the agricultural year 2006/2007 in two areas of 5,000 m2, located in in the district of Nova América, Caarapó municipality. In each sampling area, comprising 100 plots of 50 m2, 15 evaluations were performed on two plants per plot. The sampling consisted in counting the eggs. The aggregation index (variance/mean ratio, Morisita index and exponent k of the negative binomial distribution) and chi-square fit of the observed and expected values to the theoretical frequency distribution (Poisson, Binomial and Negative Binomial Positive), showed that in both cultivars, the eggs of these species are distributed according to the aggregate distribution model, fitting the pattern of negative binomial distribution.

    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. PMID:26624726

    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.

    Objective: To evaluate the diagnostic values of the superior subscapularis recess sign in patients with shoulder adhesive capsulitis. The sign consists in evaluating in MRI of the shoulder the presence of fluid distension of the bursa in the superior subscapularis recess. 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.

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.

    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.

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 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.

  6. 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

    The Eocene aged Topuk Granitoid exposing in the Tavşanlı Zone at south of the Izmir-Ankara Suture Zone is one of the granitoids which were formed as a result of collision of the Anatolide-Tauride block with the Sakarya continent in the late Cretaceous. Nearly east-west extending, elliptical shaped Topuk Granitoid was intruded into the Paleozoic and Mesozoic metamorphites and upper Cretaceous ophiolitic rocks. The intrusion is in granodiorite composition and contains spherical/ellipsoidal mafic microgranular enclaves (MME) with composition of monzodiorite to monzogabbro. The granitoid which contains xenoliths is frequently cut by porphyritic granodiorite, granite aplite and quartz dikes at the margins. Topuk Granitoid is represented by an I-type pluton with medium to high K calc-alkaline affinity and metaluminous melt composition. Ocean ridge granite (ORG) normalized element distributions show that the granitoid, dikes and MME's have similar patterns. A significant enrichment of LIL (Rb, Ba, K, Th and Sr) elements and relatively depletion of HFS (Ta, Nb, Ce, Hf, Y, Zr and Ti) elements are indicative of formation from hybrid magma in a subduction environment. In tectonic discrimination diagrams (Ta -Yb and Rb-Y+Nb), samples of the Topuk Granitoid are plotted into the volcanic arc granite (VAG) field which is characteristic for the post collision granites. The results of mineral chemistry show that plagioclases are in oligoclase-andesine (An20-49) composition, amphiboles are of magnesio-hornblende and biotites are of Fe-Mg-biotite composition. In the Al2O3-FeO-MgO diagram biotite minerals are accompanied by amphibole and other ferromagnesian minerals and represent biotites of calc-alkaline orogenic zones. Calculations based on the hornblende-barometer indicate that the calc-alkaline magma was crystallized under pressure of 2-6 kbars (mean=4 kbars) and at depth of 7-20 km (mean=12 km). The whole-rock and mineral chemistry data show that the Topuk Granitoid was formed

    In vivo systems for analyzing mutagen interactions with a specific differentiating cell population are rare. Taking advantage of the unique anatomical features of the bursa of Fabricius in the chicken, the authors explored the possibility of targeting chemical mutagens to a defined differentiating cell population in the animal, namely, the B-lymphocytes series. Such cells are known to be the targets for the oncogene-activating avian leukosis virus. Targeting of chemicals to cells of the bursa was demonstrated by application of the DNA-specific fluorochrome 4'-6-diamidino-2-phenylindole (DAPI) to the anal lips of neonatal chicks. Bright nuclear fluorescence of cells in the bursa demonstrated to occur within minutes after the application of 500..mu..l of DAPI. DAPI labeling of nuclei was detected up to several days after a single application. No nuclear labeling was exhibited in cells of neighboring tissues. Methyl methanesulfonate (MMS)(10..mu..l) was applied to the anal lips of day-old chicks to study dose-response kinetics for mutagen targeting to DNA of dividing B-lymphocytes in the bursa. Since the mitotic index was found to be quite high (25-30%) in the bursa, chromosome analysis was used to assay for genome damage. Sister chromatid exchange frequencies of 3.9, 7.3, and 9.0 (baseline 2.5) per cell were obtained at MMS dosages per animal of 50 ..mu..g, 100..mu..g, and 200..mu..g, respectively. These results indicate the rapid and quantitative localization of DNA-binding chemicals to cells of the bursa, particularly the resident B-lymphocytes. The bursa should be a useful system for studying mutagen-DNA interactions in the differentiating B-lymphocyte and subsequent influences on the development of immunity and lymphoproliferative disease.

    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. Results of the AHP consist of as follows: (1 application of pond shrimp post harvest technology and improvement of facilities and accommodation that support the quality improvement of the pond shrimps, (2 human resource quality improvement of pond farmers, collectors, and field instructors, (3 development of pond culture by applying best practices principle and local policies in order to improve the quality of the pond shrimps, and (4 improvement of interagency coordination, monitoring, and evaluation to enhance the pond shrimp quality

    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.

    2004-01-01

    Full Text Available Ten isolates of bacteria were performed from diseased black tiger shrimp collected from farms in Nakhon Si Thammarat, Patthalung, Songkhla, Satun and Patthani. All isolates belonged to Vibrio harveyi, forming rounded colonies with smooth periphery and hemolysis of red blood cells. The colonies appearedgreen and yellow on TCBS selective media and indeeded both luminescent and non-luminescent groups. To support good growth as cell proliferation, an addition of 2-8% salt to the culture media was required. Sensitivity tests against antibiotics showed that all ten isolates were sensitive to chloramphenicol, norfloxacin, trimethoprim-sulfamethoxazole, oxolinic acid, oxytetracyclin and sarafloxacin at 80, 60, 50, 40, 40 and 30%, respectively. When 12-15 g juvenile shrimp were tested for the virulence by injection, the isolates were highly virulent with OD at 640 nm in the range 0.007-0.139. The bacteria concentration of 1.60×106 - 7.27×107 CFU/ ml caused 50% juvenile mortality in ten days. The physiological changes after susceptibility included a decline in the blood cells (p<0.05, higher plasma pH (p<0.05, decrease in serum protein within 24 h (p<0.05, and a return to normal levels within 48 h. There were no differences in blood sugar levels and phenoloxidase activity between the healthy and the infected individuals. Histological study showed that at an early period of susceptibility, there were swollen tubular lumen, minor cell degeneration of the hepatic tubules and lymphoid organs and aggregation of blood cells around the degenerating cells. During 7-day susceptibility period, there was large scale cell degeneration of the hepatopancreas, lymphoid organs, gills and blood formingorgans with a great extent of blood cell aggregation and eventually mortalities occurred. During 14 day susceptibility period, there was almost entire degeneration of cells in hepatic tubules and lymphoid organs causing hepatopancreatic tubular necrosis. During this period

    In order to investigate the immunomodulatory effects and the mechanism of a Chinese herbal medicine, Zengmiansan (Astragalus immunomodulator), on immune function of chickens, three hundred 1-day-old chickens were assigned randomly into 5 groups, i.e., the blank control group, the Chinese herbal medicine Zengmiansan (ZMS)-treated group, the cyclophosphamide group, the cyclophosphamide plus levamisole group, the cyclophosphamide plus ZMS group and the control group. All chickens were immunized with Lasota vaccine by nose-drip or eye-drop at the age of 6 days. Newcastle Disease (ND) antibody titers, growth indexes of the spleen, thymus and bursa of Fabricius, the concentrations of CD4+ lymphocytes and CD8+ lymphocytes in spleen, thymus and peripheral blood, and the apoptosis of splenocytes, thymocytes and bursa of Fabricius cells were observed at the ages of 14,21, 28 and 35 days, respectively. Our results indicated that the NDV antibody titers of chickens in the Chinese herbal medicine ZMS-treated group at the ages of 14 and 21 days were significantly higher than that of the other groups (P<0.01). The growth indexes of immune organs, the concentrations of CD4+ lymphocytes and the ratio of CD4+/CD8+ T lymphocytes of chickens in the Chinese herbal medicine ZMS- treated group at the ages of 14, 21 and 28 d were significantly higher than those of the other groups (P<0.01). The apoptotic splenocytes, thymocytes and bursa of Fabricius cells of chickens in the ZMS-treated group were significantly lower than the other groups (P < 0.01) at the ages of 14, 21 and 28 days.

    Full Text Available Abstract The aim of this study was to evaluate the effect of phytogenic additives and glutamine plus glutamic acid, associated or not, on histomorphometry of bursa of Fabricius and small intestine, oocyst count and lesion scores, and carbon turnover of duodenal mucosa of broiler chickens infected with Eimeria acervulina. A total of 450 male broiler chickens was distributed into a completely randomized design with six treatments and three replications. Treatments consisted of control diet (CD; CD + coccidiosis vaccine; CD + antibiotic performance enhancers and anticoccidial (APE/AC; CD + glutamine and glutamic acid (Gln/Glu; CD + phytogenic additives (PA; CD + Gln/Glu + PA. Birds on treatment CD + vaccine were vaccinated via drinking water at three days of age against coccidiosis. At 16 days of age all birds of all treatments were inoculated orally and individually with 500,000 oocysts of Eimeria acervulina. There was no treatment effect on lesion score in the intestinal epithelium of birds. The smaller number of excreted oocysts was observed in groups of birds fed diets containing APE/AC and PA. Were observed better results of villus height and crypt depth for duodenum and ileum of birds of treatments containing Gln/Glu at 7 days of age, and Gln/Glu and PA at 21 days of age. Higher percentage of cortical area from bursa follicles was observed in birds fed diets supplemented with Gln/Glu and PA at 7, 14 and 21 days of age. Increased turnover of intestinal mucosa was observed in treatments containing Gln/Glu, indicating acceleration in development and regeneration of damaged tissue. Glutamine plus glutamic acid and phytogenic additives can provide improvements to structure, and thus to intestinal function, as well as to better immune response against the infectious challenges. Phytogenic additives can be used for coccidiosis control of broiler chickens where the use of antibiotic performance enhancers and anticoccidials is prohibited.

    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 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.

    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

    Resumo. Moela de Frango foi testada como dieta alternativa à carne para criação de Chrysomya megacephala (Fabricius visando reduzir custos e otimizar o tempo de preparação da dieta e manutenção da colônia. Quarenta larvas recém eclodidas foram colocadas em 100 gramas de dieta: moela e carne (controle. O experimento foi realizado em triplicata. A massa das lavas maduras foi registrada em balança semi-analítica e separada em lotes de cinco. Após a emergência, foram formadas três repetições de 10 pares de insetos adultos. O Desenvolvimento pós-embrionário foi avaliado pelo teste Tukey com nível a 5% de significância e a longevidade foi ajustada por regressão Weibull. A massa das lavas maduras não apresentou diferença significativa. A fase larval de moscas criadas em carne foi mais longa.

    1982-01-01

    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

    This paper describes the results of immuno-histochemical staining for chicken mannan-binding lectin (MBL) in formalin-fixed tissue sections from non-infected chickens, and from chickens infected with infectious laryngotracheitis virus (ILTV) or infectious bursal disease virus (IBDV). In the non-infected chickens, MBL was detected in the cytoplasm of a few hepatocytes and in the germinal centres of the caecal tonsils, whereas sections of kidney, heart muscle, spleen, cerebrum, thymus, adrenal gland, bursa of Fabricius, bone marrow and trachea were without staining. In the ILTV-infected chickens, an intense staining reaction for MBL was detected in the cytoplasm of all hepatocytes and on the surface of, and inside, ILTV-infected cells. Also in the IBDV-infected chickens, an intense staining reaction for MBL was detected in the cytoplasm of all hepatocytes. No staining was seen in the follicles of the bursa of Fabricius, but MBL was present in non-identified cells in the interstitium, and in the cytoplasm of macrophage-like cells, located peripheral to the ellipsoid of the spleen. These findings indicate the liver as the primary site of MBL synthesis, and points to up-regulation as a result of the viral infections. The location outside the liver could indicate a role of MBL in the immune defence. Images Figure 1 Figure 2 Figure 3 Figure 4 PMID:9708196

    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.

    The effect of dietary thyme-oil extract (TOE) supplementation on immune functions of broilers were assessed by feeding graded levels (50, 100, 200, or 400 ppm) of TOE to male broiler chicks during a 42-d feeding trial compared with negative- or positive-control diets. Dietary control treatments included a negative-control diet with no feed-additive supplementation and 2 positive-control groups supplemented with either virginiamycin or zinc bacitracin. In total, 300 1-day-old Ross × Ross male broilers were randomly assigned to 6 dietary treatments that consisted of 5 replicates of 10 birds each. On d 21 and 42, 2 birds from each replicate were killed by cervical cutting to measure the relative weights of spleen and bursa of Fabricius. At 25 d of age, chicks were injected with 0.5 mL of 10% SRBC suspension. Broilers fed with 200 ppm of TOE had heavier weights of bursa of Fabricius than those fed other dietary treatments at d 42 of age. Furthermore, dietary inclusion of 100 ppm of TOE resulted in higher (P sheep erythrocytes compared with other dietary treatments. On the other hand, diet modifications had no significant effect on blood leukocyte subpopulations and heterophil-to-lymphocyte ratio. These results suggest that dietary supplementation with TOE, especially at the level of 100 ppm, can improve immunological responses of broiler chicks. PMID:26362978

    Infection with J group avian leukosis virus (ALV-J) can result in immunosuppression and subsequently increased susceptibility to secondary infection. The innate immune system is the first line defense system in prevention of further bacterial and viral infections. Cytokines play key roles in the innate immune system. In this study, we used RT-qPCR technology to test the cytokine mRNA expression levels in various immune tissues, including the spleen, bursa of fabricius and cecal tonsil, in the days following ALV-J infection. The results indicated that in the infected group, the expression levels of interleukin-6 (IL-6), IL-18, interferon-α (IFN-α) and IFN-γ significantly increased in the spleen and reached peak levels that were thousandfolds higher than baselines at 9-12 days post-infection (d.p.i.). The levels in the bursa of fabricius slightly increased, and the levels in the cecal tonsil were not significantly altered. Moreover, the pattern of the expression of these three cytokines in the spleens of the infected group was similar to the pattern of viremia of this group. These results suggest that the spleen plays an important role in the interaction between ALV-J infection and the innate immune system. This study contributes to the understanding of innate immune responses to ALV-J infection and also elucidates the mechanisms of the pathogenicity of ALV-J in chickens. PMID:25438822

    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.

    1996-06-01

    Pathogenic serotype 1 strains of infectious bursal disease virus (IBDV) replicate efficiently in lymphoid cells of the bursa of Fabricius of chicken. Lymphoid cells in other organs are not susceptible. Apathogenic serotype 2 strains do not replicate in lymphoid bursa cells or in other lymphoid cells. Chicken embryo fibroblasts (CEF), however, efficiently replicate strains of either serotype. Binding studies showed that strains of both IBDV serotypes bind to lymphoid cells isolated from the bursa, thymus or spleen, indicating that restriction of IBDV replication to lymphoid B cells is not determined by the presence of specific receptor sites. The specificity of binding was demonstrated by saturation and competition experiments. These revealed the presence of different receptors: CEF had receptors common to both serotypes and specific ones for each serotype. Receptor sites common to both serotypes were also present on lymphoid cells; however, additional serotype-specific sites were only demonstrated for the apathogenic serotype 2 strain. Strains of both serotypes specifically bound to proteins with molecular masses of 40 kDa and 46 kDa, exposed on the surface of CEF and lymphoid cells. Competition experiments indicated that these proteins might represent the common receptor sites of IBDV. PMID:8683211

    Full Text Available The current study was conducted to evaluate the pathogenicity and immunosuppressive effects of GM-97 strain of infectious bursal disease virus in commercial broiler chickens. A total of 500 broiler chickens were vaccinated with the virus through oral route at 10 and 17 days of age (102-103 EID50/dose. Chickens were also vaccinated with Newcastle disease virus (Hitchner B1 orally at 14 and 21 days old. Chickens were euthanized (at 12, 14, 16, 20, 23, 26 days of age after measuring body weight. Bursa of Fabricius was examined for any gross lesion, weighed and processed for histological investigations. Bursa to body weight ratio and bursal lesion scoring were made to evaluate pathogenicity of the virus. Blood samples were analyzed for antibody response to ND vaccine virus using HI test. Results showed that the GM-97 strain of IBDV induced mild to moderate depletion of lymphoid cells in the center of bursal follicles and non-significant difference in bursa to body weight ratio amongst vaccinated and unvaccinated chickens. Chickens responded well to ND vaccine by mounting high level of serum NDV specific HI antibody titers. It can be concluded from the present study that GM-97 strain of IBDV has mild pathogenicity but is not immunosuppressive.

    Full Text Available The affixes used during the verb processing in the Turkey Turkish dialects show important phonetic variations. These affixes, which are commonly used in all the Turkey Turkish dialects, differ from one region to another, even from one village to another in the same region, in having varying phonetic characteristics. Of these affixes, those which undergo change most frequently and function as a key to the determination of the ethnic structure of the region in question are the future tense and present continuous tense suffixes. In Bursa local dialects, the final phoneme /r/ of the present continuous tense suffix –(Iyor predominantly was omitted and the neighboring vowel was lengthened. However, we observe that the initial vowel of the future tense suffix –AcAk was omitted and the back vowel /a/ was changed to the front vowel /e/ in the second syllable. We come across some different uses in the person suffixes following these suffixes. In this article, it is aimed to put forth various uses of the affixes in question and other verb processing affixes used in the local dialects of Bursa. Türkiye Türkçesi ağızlarında fiil işletimi sırasında kullanılan ekler, önemli fonetik değişiklikler göstermektedir.

    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

    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

    Deregulated reactive oxygen species (ROS) production can lead to the disruption of structural and functional integrity of cells as a consequence of reactive interaction between ROS and various biological components. Catalase (CAT) is a common enzyme existing in nearly all organisms exposed to oxygen, which decomposes harmful hydrogen peroxide, into water and oxygen. In this study, the full length sequence that encodes CAT-like protein from Spodoptera litura named siltCAT (GenBank accession number: JQ_663444) was cloned and characterized. Amino acid sequence alignment showed siltCAT shared relatively high conservation with other insect, especially the conserved residues which defined heme and NADPH orientation. Expression pattern analysis showed that siltCAT mRNA was mainly expressed in the fat body, midgut, cuticle and malpighian tube, and as well as over last instar larvae, pupa and adult stages. RNA interference was used to silence CAT gene in SL-1 cells and the fourth-instar stage of S. litura larvae respectively. Our results provided evidence that CAT knockdown induced ROS generation, cell cycle arrest and apoptosis in SL-1 cells. It also confirmed the decrease in survival rate because of increased ROS production in experimental groups injected with double-stranded RNA of CAT (dsCAT). This study implied that ROS scavenging by CAT is important for S. litura survival. PMID:23555693

    The objective of this work was to study the effects of gamma and ultraviolet radiations in isolates of M. anisopliae and the utilization of this pathogen, aiming the polulation control of the sugarcane borer, D. saccharalis. To evaluate the application of M. anisopliae under field conditions, two experiments were carried out, the first consisting of a spore suspension application upon sugarcane borer egg masses, and the second consisting of a pulverization of spores upon egg masses previously placed on sugarcane leaves. The dosages utilized were of 100, 200 and 300 g of spores/ha. The results obtained in both trials indicated that the deposition of spores on D. saccharalis egg masses was difficulted by the sugarcane foliar mass. (author)

    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

GC and MS were used to analyze volatile oils. Aromatic turmerone, α-turmerone and zingiberene were also obtained. 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.

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.

    The influence of in ovo bursectomy on the levels of J and mu chains in the sera of embryonic and hatched chicks was studied by the dot blotting immunoassay. The results indicated a decrease in the level of J chains during the embryonic stage after treatment with testosterone compared with normal chicks. Testosterone treatment caused a decrease in J-chain levels after hatching which was more marked in reduced-alkylated than in non-reduced sera. In contrast, testosterone caused no significant change in serum levels of mu chains, either in ovo or after hatching. Our findings further present the paradox that although removal of the bursa of Fabricius by testosterone treatment did not impair mu-chain synthesis, B-cell differentiation was suppressed. These observations indicate that in ovo bursectomy selectively inactivates B-cell differentiation as indicated by the induction of immunodeficiency, and results in the failure of J-chain production.

    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.

    Full Text Available The lacewings (Ceraeochrysa cincta are important predators found associated to many pests in several agroecosystems. Eggs of Sitotroga cerealella and Anagasta kuehniella are used traditionally for massal rearing of these predators. Other foods can be used in substitution to the traditional ones, but little is known about the biology of lacewings and other alternative foods. So, this work was carried out to evaluate the effect of different diets on the post-embryonic development of C. cincta in laboratory. After been individualized in glass tubes, each larva was fed with S. cereallella and Diatraea saccharallis. It was evaluated the larvae duration, weight and viability in each instar, the duration, weight and viability of the pupa and pre-pupa stages and the duration of the post-embryonic period. It was adopted a completely randomized design with ten replications per treatment, each consisting of five eggs or larvae of C. cincta. Larvae were weighed 48 hours after hatching and 48 hours after each molt, and pre-pupae and pupae, 48 hours after starting these stages. There was no effect of the kind of food provided on the parameters evaluated. Therefore, D. saccharallis eggs can be used to feed C. cincta.Os crisopídeos são importantes predadores encontrados associados a diversos artrópodes-praga em diversos agroecossistemas.

    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 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.

  11. Induction of apoptosis in chicken bursal B cells

    International Nuclear Information System (INIS)

    Cell death in general can be a physiological process of cell number regulation in tissue, or it can be the result of exo or endogenous injuries, such a low-dose of radiation. Chicken B cell population in the bursa of Fabricius are very susceptible to PCD. Our present studies concern the development of radiation damage of chicken defence mechanisms. In 6 experiments pathogen free chicken were irradiated by gamma rays with the total doses of 0.25, 0.5, 1.0, 2.0 and 4.0 Gy. The induction of apoptosis was checked by Flow-cyto-meter 12 h after irradiation in bursa cell suspension. There is some increase in the number of induced apoptotic cells 12 h after irradiation at the dose 0.5-.4.0 Gy. There were no significant changes in the proportion of proliferating lymphocytes (G2 M), but cellularity decreased significantly at dose 2.0 and 4.0 Gy/12 h after irradiation. (author)

    Full Text Available Infectious Bursal Disease (IBD is a chicken disease economically important for the poultry industry in function of the immune depression that it causes. Disease control is made with different vaccines and vaccination programs. In present work, the pathogenicity of 3 intermediate vaccines (I1, I2 and I3, 2 intermediate more pathogenic (IP1 and IP2 and 3 vaccines containing strong virus (F1, F2 and F3 was evaluated. Birds vaccinated with IP1, IP2, F1, F2 and F3 showed significantly lower bursa size in relation to control animals and animals vaccinated with I1, I2 and I3. On the other hand, vaccines I1 and I3 induced antibody titers higher than the control and lower than I2, IP1, IP2, F1, F2 and F3. Histological scores showed that vaccines I1, I2 and I3 induced similar injury degree, although I2 and I3 were not different from the control, whereas I1 was slightly different. Strong vaccines induced more pronounced lesions than the other tested vaccines. These findings suggest that strong vaccines are able to cause severe bursal injuries. However, bursometry and relative weight of the bursa of Fabricius were considered inadequate to evaluate vaccine pathogenicity. Moreover, strong vaccines induced higher antibody titers than the other vaccines, although some intermediate vaccines induced similar titers.

    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.

  14. Some gamma radiation (60Co) effects on Chrysomya megacephala (Fabricius, 1794) (Diptira-Calliphoridae)

    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.

    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.

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.

    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.

    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.

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. O rearranjo foi interpretado como sendo autossômico e heterozigoto, caracterizado pela translocação envolvendo dois pares de homólogos submetacêntricos: o par 10, que possivelmente tem um dos elementos com uma inversão pericêntrica, e o par 6, que possui em seu braço curto duas constrições secundárias, diferenciando satélites em suas extremidades.

    Peptide transporters 1 and 2 (PepT1 and PepT2) and peptide/histidine transporter 1 (PHT1) are all members of the proton-coupled oligopeptide transporter family, which are important for the transport of amino acids in peptide form. The PepT1 acts as a low-affinity/high-capacity transporter and PepT2 as a high-affinity/low-capacity transporter for di- and tri-peptides. The PHT1 transports di- and tri-peptides as well as histidine. The objective of this study was to profile PepT1, PepT2, and PHT1 mRNA expression in the proventriculus, duodenum, jejunum, ileum, ceca, large intestine, brain, heart, bursa of Fabricius, lung, kidney, and liver in layer chicks on embryonic d 18 and 20 and d 1, 3, 7, 10, and 14 posthatch. Absolute quantification real-time PCR was used to measure gene expression. Expression of PepT1 was greatest in the duodenum, jejunum, and ileum. Expression of PepT1 increased in the duodenum, jejunum, and ileum from late embryonic stages to posthatch and in the large intestine from late embryonic stages to d 10 posthatch. In the ceca, PepT1 expression increased from embryonic d 20 to d 1 posthatch and then decreased. Expression of PepT2 was greatest in the brain and kidney. Expression of PepT2 increased from d 10 to 14 in the bursa of Fabricius and decreased in the proventriculus, duodenum, jejunum, and liver from late embryonic stages to posthatch. In the small intestine and liver, PepT2 may function to transport di- and tri-peptides during embryogenesis. The PHT1 was expressed in all tissues analyzed. Expression of PHT1 increased in the jejunum, large intestine, brain, and liver posthatch and decreased in the proventriculus from embryonic stages to posthatch. A tissue × age interaction was observed for all genes. The uptake of peptides in the developing chick is regulated by peptide transporters that are expressed in a tissue- and development-specific manner. PMID:23571341

    Full Text Available AIM/BACKGROUND: The aim of this study was to evaluate socio-demographic and fertility features, opinions on consanguinity, and the types of congenital disorders encountered in the babies of women in consanguineous marriages in the Nilufer Public Health Training and Research Area in the province of Bursa in northwest Turkey. METHODS: This case-control study was conducted between September 2005 and March 2006. The case group consisted of 393 women in consanguineous marriages in the Nilufer Public Health Training and Research Area; the control group consisted of 393 women of similar age living in the same neighborhoods but in non-consanguineous marriages. RESULTS: Women involved in a consanguineous marriage were on average younger than women in the control group. The mean numbers of pregnancies, births, stillbirths, and living and deceased babies were all significantly higher among the consanguineous marriages. When the sample and the control groups were compared, it was obtained that the women in the case group were socio-economically in a lower status statistically, by means of their husband’s and their own education and occupational status, than the women in the control group. The women in the case group were more likely to believe that consanguinity is not detrimental to a child’s health, and they approved of consanguineous marriages for their own children. These opinions were held despite there being a significantly higher incidence of congenital disorders among the children of the consanguineous marriages. CONCLUSION: Women there should be offered genetic counseling to help reduce the occurrence of children being born with congenital abnormalities. [TAF Prev Med Bull 2008; 7(2.000: 107-112

    Full Text Available AIM/BACKGROUND: The aim of this study was to evaluate socio-demographic and fertility features, opinions on consanguinity, and the types of congenital disorders encountered in the babies of women in consanguineous marriages in the Nilufer Public Health Training and Research Area in the province of Bursa in northwest Turkey. METHODS: This case-control study was conducted between September 2005 and March 2006. The case group consisted of 393 women in consanguineous marriages in the Nilufer Public Health Training and Research Area; the control group consisted of 393 women of similar age living in the same neighborhoods but in non-consanguineous marriages. RESULTS: Women involved in a consanguineous marriage were on average younger than women in the control group. The mean numbers of pregnancies, births, stillbirths, and living and deceased babies were all significantly higher among the consanguineous marriages. When the sample and the control groups were compared, it was obtained that the women in the case group were socio-economically in a lower status statistically, by means of their husband’s and their own education and occupational status, than the women in the control group.

    Full Text Available Oviposition response of Heliconius erato phyllis (Fabricius, 1775 (Lepidoptera, Nymphalidae to variation in host plant availability, Passiflora suberosa Linnaeus (Passifloraceae, and to presence of conspecific eggs and larvae was determined through choice experiments performed under insectary conditions. Freeze dried, painted eggs and larvae were used as mimics for testing presence of conspecific effects. Females laid more eggs on intact P. suberosa shoots without conspecifics than on those with H. erato phyllis egg and first instar mimics in both simultaneous and sequential choice trials. Oviposition response to variation in host plant availability was determined through no-choice trials, under host plant densities varying from 0.3 to 8.3 plants per female. Number of eggs laid per plant decreased exponentially with an increase in plant availability. On the contrary, daily oviposition rates (eggs /female/day increased with an increase in plant number, and levelled off when the number of plants available for oviposition was greater than potential fecundity of females. Thus, it is inferred from the results that females assess egg and larval load and prefer to lay eggs on shoots free from conspecifics. It is also inferred that they are able to recognize plant abundance and are unwilling to lay more than one egg per shoot even when host availability is scarce, as judged by reduction in daily oviposition rates under low host plant number. The consequences of laying isolated eggs on P. suberosa shoots are discussed from the viewpoint of intraspecific competition in the larval stage of H. erato phyllis.

    [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

    This study was designed to detect reticuloendotheliosis virus (REV) as a contaminant in fowl pox vaccines. A total of 30 fowl pox vaccine samples were examined for the presence of REV using both in vitro and in vivo methods. In in vitro testing, the fowl pox vaccine samples were inoculated into chicken embryo fibroblast cultures prepared from specific-pathogen-free embryonated chicken eggs, and the cultures were examined using PCR to detect REV. In in vivo testing, each fowl pox vaccine sample was inoculated into 5-d-old specific-pathogen-free chicks, which were kept under observation for up to 12 wk postinoculation; serum samples were collected at 15, 30, and 45 d postinoculation for the detection of REV-specific antibodies using ELISA. Tissue samples were collected at 8 and 12 wk postinoculation for histopathological examination. Of the tested vaccines, only one imported vaccine sample tested positive for REV using PCR. Serum samples collected from chicks infected with the PCR-positive vaccine batch also tested positive for REV-specific antibodies using ELISA. Histopathological examination of the liver, spleen, and bursa of Fabricius demonstrated the presence of tumor cells in these organs, confirming the results obtained using PCR and ELISA, and indicating that the sample was contaminated with REV. These data clearly indicate that the screening of all commercial poultry vaccines for viruses is an important factor in assuring the biosafety of animal vaccines. PMID:20952701

    An investigation was carried out to determine the prevalence and infection pattern of duck circovirus (DuCV) in subclinical Pekin ducks on South Korean duck farms. A total of 147 samples collected from 92 duck farms in five provinces were examined from 2011 to 2012. The overall prevalence of DuCV PCR-positive pooled bursa of Fabricius and liver samples was 21.8% (32/147). The prevalence of DuCV PCR-positive samples increased significantly in 3-week-old ducks compared with that in 1-week-old ducks (P<0.05). DuCV in association with Riemerella and Salmonella infections (10.9%; 16/147) occurred at the same level as infection with DuCV alone (10.9%; 16/147). In comparison of the relationship between bacterial diseases (salmonellosis, Riemerella infection) and morbidity in farms with and without DuCV, morbidity was higher in circovirus-positive farms (50%; 16/32) than in circovirus-negative farms (26.1%; 30/115). Our findings provide baseline information on the degree of DuCV infection and distribution and pattern of DuCV in ducks, and it is evident that DuCV can be associated with subclinical diseases and that subclinical infection could be economically important.

    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

    Infectious laryngotracheitis (ILT) is an acute, highly contagious upper-respiratory infectious disease of chickens. In this study, a real-time PCR method was developed for fast and accurate detection and quantitation of ILTV DNA of chickens experimentally infected with ILTV strain LJS09 and naturally infected chickens. The detection lower limit of the assay was 10 copies of DNA. There were no cross reactions with the DNA and RNA of infectious bursal disease virus, chicken anemia virus, reticuloendotheliosis virus, avian reovirus, Newcastle disease virus, and Marek's disease virus. The real-time PCR was reproducible as the coefficients of variation of reproducibility of the intra-assay and the inter-assay were less than 2%. The real-time PCR was used to detect the levels of the ILTV DNA in the tissues of specific pathogen free (SPF) chickens infected with ILTV at different times post infection. ILTV DNA was detected by real-time PCR in the heart, liver, spleen, lung, kidney, larynx, tongue, thymus, glandular stomach, duodenum, pancreatic gland, small intestine, large intestine, cecum, cecal tonsil, bursa of Fabricius, and brain of chickens in the infection group and the contact-exposure group. The sensitivity, specificity, and reproducibility of the ILTV real-time PCR assay revealed its suitability for detection and quantitation of ILTV in the samples from clinically and experimentally ILTV infected chickens.

    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.

    The innate responses of cecal tonsils against invading microorganisms are mediated by conserved pattern recognition receptors (PRRs) such as the Toll-like receptors (TLRs). TLRs expressed by mammalian and avian immune system cells have the capability to recognize pathogen-associated molecular patterns (PAMPs). Although, the role of TLR ligands in innate and adaptive responses in chickens has been characterized in spleen and bursa of Fabricius, considerably less is known about responses in cecal tonsils. The aim of the current study was to assess responses of mononuclear cells from cecal tonsils to treatment with the TLR2, TLR4 and TLR21 ligands, Pam3CSK4, lipopolysaccharide (LPS), and CpG oligodeoxynucleotide (ODN), respectively. All three ligands induced significant up-regulation of interferon (IFN)-γ, interleukin (IL)-1β, IL-6 and CxCLi2/IL-8, whereas no significant changes were observed in expression of IL-13 or the antimicrobial peptides, avian β-defensin (AvBD) 1, AvBD2 and cathelicidin 3 (CATHL-3). In general, CpG ODN elicited the highest cytokine responses by cecal tonsil mononuclear cells, inducing significantly higher expression compared to LPS and Pam3CSK4, for IFNγ, IL-1β, IL-6 and CxCLi2 at various time points. These findings suggest the potential use of TLR21 ligands as mucosal vaccine adjuvants, especially in the context of pathogens of the intestinal tract. PMID:27185259

    In this study, a novel Lactococcus garvieae B301 was isolated from the intestinal tract of a healthy piglet. L. garvieae B301 was tolerant to acid pH, simulated gastric and small intestinal transit juices, indicating that it was capable of surviving in the gastrointestinal tract. L. garvieae B301 was safe and beneficial to broilers, as broiler chickens supplemented with L. garvieae B301 had lower diarrhoea incidence and mortality than the Control. Moreover, supplementation of broiler diets with L. garvieae B301 resulted in an increase in body weight and the number of caecum lactic acid bacteria and Bifidobacterium spp., and decrease in feed-to-gain ratio and the number of caecum coliforms. It also had a positive effect on the thymus index and bursa of Fabricius index and enhanced serum levels of immune globulins. All these results showed that L. garvieae B301 could enhance the growth performance of broiler chickens and improve their health. Thus, L. garvieae B301 could be a promising feed additive for broiler chickens. PMID:26331590

    The authors studied the effects of environmental contaminants on immune function and related biochemical and histological biomarkers in herring gulls (Larus argentatus) and Caspian terns (Sterna caspia) from the Great Lakes. An epidemiological analysis strongly supported the hypothesis that suppression of T-cell-mediated immunity was associated with high perinatal exposure to persistent organochlorines (primarily PCBs). Suppression of T cell function (measured by the phytohemagglutinin skin test) was most severe in colonies in Lake Ontario and Saginaw Bay for both species and in western Lake Erie (1992) for herring gulls. In herring gull chicks, the mass of the thymus decreased as liver EROD increased. Both species exhibited biologically significant differences among sites in anti-SRBC antibody titers, but there were few associations with organochlorines. In Caspian terns and, to a lesser degree, in herring gulls, plasma retinol decreased as organochlorines increased. In both species, plasma thyroxine concentrations differed significantly among sites, but there were no apparent associations with contaminants. Although thyroxine and retinol often are associated with immune function in laboratory studies, there were few consistent relationships between these variables and T-cell- and antibody-mediated immunity in this field study. These biochemical variables may be poor surrogate biomarkers for immune function in wild birds, although they are important indicators for other physiological systems. The histology of the thymus, bursa of Fabricius, and spleen were examined for developmental and functional abnormalities and the presence of infections.

    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.

    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.

    Background and purpose A retrocalcaneal bursitis is caused by repetitive impingement of the bursa between the Achilles tendon and the posterosuperior calcaneus. The bursa is situated in the posteroinferior corner of Kager's triangle (retrocalcaneal recess), which is a radiolucency with sharp borders on the lateral radiograph of the ankle. If there is inflammation, the fluid-filled bursa is less radiolucent, making it difficult to delineate the retrocalcaneal recess. We assessed whether the ra...

    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

    The objective of this study was designed to test whether supplementation of the diet with arginine (Arg) or glutamine (Gln) or their combination influences the production, organ weights and humoral immune response of broilers. A total of 432 one-day-old male Ross 308 broiler chickens were divided into 6 treatment groups: control, Arg-0.5%, Arg-1%, Gln-0.5%, Gln-1% and Arg-0.5%+Gln-0.5%. Drinking water and feed were provided ad libitum. On day 18 of the experiment 50% of chickens in each treatment group were immunised with bovine serum albumin. Ten and 21 days after immunisation blood samples were collected to determine the anti-albumin IgY titre, interleukin 6 (IL6) and interferon gamma (IFNG) and to measure the weight of the liver, spleen, bursa of Fabricius and thymus. Arg or Gln supplementation of the diets influenced neither the production nor the organ weights until 18 days of age. Between 18 and 39 days of age both Arg (0.5% and 1%) and Arg + Gln supplementation improved the feed conversion ratio (FCR) by 3.7%, 6.3% and 4.9%, respectively, while Gln-1% worsened it by 15%. Immunisation slightly (-0.79%) depressed the body weight gain of broilers fed the control diet, which was significantly improved by both Arg (0.5 or 1%) and Arg + Gln supplementation. Immunisation increased the weight of the spleen, bursa and thymus and decreased that of the liver. Supplementation with 1% Gln depressed (-5.13%) the body weight gain of the immunised chickens but strongly stimulated the immune response. Supplementations with Arg and Gln did not influence the IL6 and IFNG level of the blood; however, on day 10 after immunisation these two parameters showed a negative correlation with each other. Regarding production, organ weights and immunity, Arg supplementation should be recommended in the grower phase, while Gln supplementation can be useful in pullets raised for egg production, where a good immune response to vaccinations is an important factor.

    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

The study was carried out with pupae of Macrothorax rugosus (Fabricius, 1792, Hadrocarabus dufouri (Dejean, 1831, H. lusitanicus (Fabricius, 1801 and Rhabdotocarabus melancholicus (Fabricius, 1798 reared in the laboratory from adults caught in the field. By determining and testing various morphological structures, all three genera were identified. These results indicate that the presence or absence of setae on the pronotum, the distribution of hairs on the abdominal tergi and the development of tergal expansions from urotergi are the most significant features for identification.

    The production performance, efficacy, and safety of two types of vaccines for infectious bursal disease virus (IBDV) were compared with in-ovo vaccination of Cobb 500 broiler chickens for gross and microscopic examination of the bursa of Fabricius, bursa/body weight (b/B) ratio, flow cytometry, and serologic response to Newcastle disease virus (NDV) vaccination. One vaccine was a recombinant HVT-IBD vector vaccine (HVT as for herpesvirus of turkeys) and the other was an intermediate plus live IBDV vaccine. A significant difference was detected at 21 d. Eight of 10 chickens that received the IBDV live vaccine had severe bursal lesions and a relatively low b/B ratio of 0.95, and an inhibited NDV vaccine response. On the other hand, the HVT-IBD vector vaccine resulted in mild bursal lesions and a b/B ratio of 1.89. Therefore, the live vaccine had lower safety than that of the HVT-IBD vector vaccine. To determine the protective efficacy, chickens were intraocularly challenged at 24 d. Eight of 10 chickens in the IBDV live vaccination group showed gross and histological lesions characterized by hemorrhage, cyst formation, lymphocytic depletion, and a decreased b/B ratio. In contrast, the HVT-IBD vector vaccinated chickens showed mild gross and histological lesions in three of 10 chickens with a b/B ratio of 1.36, which was similar to that of the unchallenged controls. Vaccinated chickens showed a significant increase in IBDV antibody titers, regardless of the type of vaccine used. In addition, significantly better broiler flock performance was observed with the HVT-IBD vector vaccine compared to that of the live vaccine. Our results revealed that the HVT-IBD vector vaccine could be used as an alternative vaccine to increase efficacy, and to have an improved safety profile compared with the IBDV live vaccine using in-ovo vaccination against the Korean very virulent IBDV in commercial broiler chickens.

    Full Text Available The aim of the study is to investigate the hydrogeochemical processes that control the chemistry of groundwater in the İnegöl Basin (Bursa, and to assess for its availability of groundwater for different purposes. Alluvium is the most important aquifer in the basin. In addition, groundwater can be supplied from conglomerate and sandstone levels of the İnegöl formation which is located in the base of alluvium. Kocasu stream which is supplied surface water discharge of the basin is also controlled groundwater discharge of the basin. Insitu measurements and chemical analyses of groundwater were made in two period point of view determination of quality and chemical structure of groundwater. Groundwater is Ca-Mg-HCO facies in wet season and Mg-Ca-HCO3 facies in dry season due to increases of Mg2+ ion. The increase of Mg2+ is related to solubility of dolomite and decomposition of magnesium minerals. Mn and Fe concentrations of groundwaters are exceed to drinking water standards in specific locations. These increases are based on water rock interaction with İnegöl and Nilüfer formations and anthropogenic factors. USSL and Wilcox diagrams, sodium adsorption ratio, percentage of sodium, residual sodium carbonate, and permeability index were used to determine of availability as irrigation water.

    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

    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 study interactions between avian leukosis virus subgroup J (ALV-J) and reticuloendotheliosis virus (REV) and the effects of co-infection on pathogenicity of these viruses, 1-day-old broiler chicks were infected with ALV-J, REV or both ALV-J and REV. The results indicated that co-infection of ALV-J and REV induced more growth retardation and higher mortality rate than ALV-J or REV single infection (P < 0.05). Chickens co-infected with ALV-J and REV also showed more severe immunosuppression than those with a single infection. This was manifested by significantly lower bursa of Fabricius and thymus to body weight ratios and lower antibody responses to Newcastle disease virus and H9-avian influenza virus (P < 0.05). Perihepatitis and pericarditis related to severe infection with Escherichia coli were found in many of the dead birds. E. coli was isolated from each case of perihepatitis and pericarditis. The mortality associated with E. coli infection in the co-infection groups was significantly higher than in the other groups (P < 0.05). Among 516 tested E. coli isolates from 58 dead birds, 12 serotypes of the O-antigen were identified in two experiments. Different serotypes of E. coli strains were even isolated from the same organ of the same bird. Diversification of O-serotypes suggested that perihepatitis and pericarditis associated with E. coli infection was the most frequent secondary infection following the immunosuppression induced by ALV-J and REV co-infection. These results suggested that the co-infection of ALV-J and REV caused more serious synergistic pathogenic effects, growth retardation, immunosuppression, and secondary E. coli infection in broiler chickens.

    Avian necrotic enteritis (NE) induced by Clostridium perfringens is a disease that affects mainly the first weeks of poultry's life. The pathogenesis of NE is complex and involves the combination of several factors, such as co-infection with different species of coccidia, immunosuppression and stress. Stress is one of the main limiting factors in poultry production. Although several studies emphasized the effects of stress on immunity, few works analyzed these effects on immunoglobulins and on germinal centres (GCs), which are specialized microenvironments, responsible for generating immune cells with high affinity antibodies and memory B-lymphocytes. Thus, the effects of heat stress associated or not with thioglycolate broth culture medium intake and/or C. perfringens infection on corticosterone serum levels, spleen GCs development and immunoglobulin production in broilers were evaluated. Results showed that heat stress, thioglycolate and C. perfringens per se increased corticosterone serum levels, although this was not observed in heat stressed and thioglycolate and C. perfringens-treated chickens. The serum levels of IgA, IgM and IgY were differently affected by heat stress and/or infection/thioglycolate. Heat stress decreased the duodenal concentrations of sIgA, which was accompanied by a reduction in GCs number in the duodenal lamina propria; a trend to similar findings of sIgA concentrations was observed in the chickens' jejunum. Changes in spleen and Bursa of Fabricius relative weights as well as in spleen morphometry were also noted in heat stressed animals, infected or not. Together, these data suggest that heat stress change GCs formation in chickens infected or not, which that may lead to failures in vaccination protocols as well as in the poultries' host resistance to infectious diseases during periods of exposure to heat stress.

    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.

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.

    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.

    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.

    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.

    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. These results demonstrated that Bt rough rice has no negative impacts on the host preference behaviors of non-target stored product pest R. dominica and its parasitoid A. calandrae. PMID:26150137

    International Nuclear Information System (INIS)

    We examined daily flight patterns and the correlation between adult age and flight in Cylas formicarius in the laboratory at 25 ± 1 ℃ under a 14L10D photoregime by a simple method of counting the number of adults flying out of a cup. The flight activity of males peaked just after the onset of darkness and gradually decreased toward the onset of light. Only a small proportion of them flew during the photophase. More than 90% of male adults flow at least once within 2 weeks after exodus from the sweet potato tuber. The proportion of males flying per day increased to a maximum 1 week after the exodus, and about 10% of them flow even 30 days after the exodus. On the other hand, flight activity of females was low and the proportion of females flying at least once was about 25%. Females flow from 7 to 24 days after the exodus

    Full Text Available Chrysomya megacephala (Diptera: Calliphoridae, popularly known as blowfly, has a great capacity for dispersion and, due to factors such as food abundance and favorable climate, it colonizes Brazil completely in a short time. These insects are important to the sectors of epidemiology, public health and forensics, especially due to carrying microorganisms such as bacteria, viruses, protozoa and helminthes, which are responsible for the spread of diseases such as dysentery, cholera, botulism, typhoid fever, brucellosis, polio, smallpox and tuberculosis. The objective of this study was to verify the diversity of bacteria carried by this species in the Federal University of Mato Grosso – Campus of Sinop during the month of January of 2012. The flies were collected using two traps baited with 100 g of fresh sardines on each and maintained in the field for 24 hours. Twenty specimens of C. megacephala were placed in Petri dishes, to walk for two minutes upon Nutrient Agar (NA. After establishment of the colonies, isolation of the bacteria on the NA medium and their multiplication in test tubes containing the same culture medium was performed, and later sent to identification by gas chromatography. The bacteria encountered were Aquaspirillum polymorphum; Burkholderia ambifaria; Burkholderia anthina; Burkholderia cepacia; Burkholderia cenocepacia; Burkholderia pyrrocinia; Burkholderia stabilis; Paenibacillus macerans; Virgibacillus pantothenticus, Bacillus subtilis e Photorhabdus luminescens luminescens, with the last two species considered of importance in the plant protection sector.

    Objective: To find out the most resistant strain of Spodoptera litura (S. litura) from Tamil Nadu, Kerala and Karnataka by synthetic insecticide treatment. Methods:Using leaf disc no-choice method, the insects were tested with different doses for pesticides. The LC50 and LC90 values were calculated by probit analysis. Results:In the insect bioassay, the cypermethrin insecticide showed significantly higher LC50 values of 14.699 g/L and 15.738 g/L against the Tamil Nadu and Kerala S. litura insect cultures respectively. The body length of 2nd, 3rd and 4th instar larvae were significantly higher (P≤0.05) in TTP insect population [(19.2±2.3) mm, (28.05±3.20) mm, (36.1±2.0) mm], when compared with KTK [(18.5±2.7) mm, (23.38±2.00) mm, (31.75±2.70) mm] and control, KBB [(15.65±2.30) mm, (23.65±2.70) mm, (33.2±2.2) mm] populations. The body breadth of 3rd instar larvae was significantly higher (P≤0.05) in TTP insect population (4.9±1.1) mm, when compared with KTK (3.93±0.80) mm and control, KBB (3.65±0.70) mm populations. Conclusions: The present study clearly showed that field collected strains were highly resistant when compared to control. Based on our study, we conclude that reduced use of synthetic pesticides is necessary and IPM is a better way to reduce the development of pesticide resistance among strains of S. litura.

The chickens were grouped into four: i infected with vvIBDV; iivaccinated with commercial vaccine + challenge with vvIBDV; iii vaccinated using locally produced vaccine+ challenged with vvIBDV; and iv control group (unvaccinated animals. Pathogenecity was analyzedbased on the sequence of infection; the distribution and degree of gross pathology and histopathologylesions on bursa Fabricius, spleen and thymus in relation to the presence of the antigen (IBDV Ag whichwas detected using immunohistochemistry technique. During the acute phase (1-3 days following theexperimental infection hyperemia and exudation on the bursa Fabricius were observed in the infectedgroup and the two vaccinated-challenged groups. Similarly, hyperemia was also observed on the spleenand thymus. Whilst during the chronic stages (at 7 and 14 days following the experimental infection thebursa showed atrophy. Upon histological examination, the bursa showed interstitial edema, hemorrhage,infiltration of heterophyl cells and fibroblast hyperplasia. The bursa lymphoid follicles were depleted dueto cells necrosis and apoptosis. Plica epithelial layer was wrinkled and the Goblet cells metaplasia formedhyper plastic cysts. In the spleen and thymus severe reticulo endothelial cells proliferation was observedduring the acute stage and tended to decline during the chronic stage. During the acute and chronic stagescells containing IBDV Ag were detected in the bursa Fabricius, distributed within the mantle zone andgerminal center of lymphoid follicles in the two vaccinated-challenge groups. Whereas in the infectedgroup, the IBDV antigen were detected up to 7 days post the infection. Nevertheless, neither IBDV antigenwas detected in the spleen nor in the thymus in all the experimental groups. The results of this studyclearly explained the ferocity of

We report a 15-year-old boy with a rapidly expanded adventitious bursitis overlying an osteochondroma of the humerus facing the thoracic wall, a location not previously reported for such bursa formation. Magnetic resonance imaging readily showed adventitious bursitis overlying the osteochondroma, thereby dispelling concerns for malignant transformation.

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

    Full Text Available ABSTRACTSReverse mean reversion and predictability of stock return is probably the most well researched topic in the empirical research of financial economics. 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. This evidence supports the mean reversion hypothesis that stock price are not pure random walks and predictability of stock return and reject the random walk hypothesis.

    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.

    Full Text Available Research on stock splits has frequently been undertaken. The results vary, but fundamentally can be classified into two groups. First, the stock split is purely "cosmetic". Second, the stock split has a real effect on stocks. The difference between these opinions raises controversy. 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. On the other hand, the test of a relationship in a portfolio reveals that only stock prices significantly affect the bid-ask spread. Abstract in Bahasa Indonesia : Penelitian mengenai stock split sudah sering dilakukan. Hasil dari penelitian- penelitian tersebut bermacam - macam, tetapi pada dasarnya dapat dibedakan menjadi dua kelompok. Pertama, stock split dinyatakan murni hanya sebagai "kosmetik".

Tujuan dari penelitian ini adalah untuk menguji kembali apakah betul stock split dapat mempengaruhi likuiditas dan return saham baik ditinjau secara individual untuk masing - masing saham maupun seluruh saham sebagai sebuah portofolio. Secara keseluruhan, hasil dari penelitian ini menunjukkan bahwa stock split hanya mempengaruhi harga, volume perdagangan dan persentase spread, tetapi tidak mempengaruhi varians dan abnormal return baik ditinjau secara individual maupun sebagai sebuah portofolio.

    The study was conducted in order to investigate the immuno-enhancing property of the Chinese herbal formula, Gan lian Yu ping feng powder. Three hundred and thirty six 45-day-old chicks were randomly divided into eight groups. The chicks in groups A, B, C were orally given 0.25 g/mL (low-), 0.5 g/mL (middle-) and 1.0 g/mL (high) dose of Gan lian Yu ping feng powder in the drinking water respectively for 3 days consecutively. They were then immunised with infectious laryngotracheitis vaccine (ILTV) on the 4th day. Groups D, E, F were given 0.25 g/mL, 0.5 g/mL and 1.0 g/mL dose of Gan lian Yu ping feng powder respectively after the immunisation for three days consecutively. Group G was Wen du qing (a government approved herbal product for ILT) control group, and group H was blank control group. At 52, 59, 73, 87 days of age, 8 chicks of each group were selected randomly for blood sampling to determine the levels of IFN-γ, IL-4 and the antibody of ILT. Then the chickens were sacrificed, with the thymus, spleen and Bursa of Fabricius being weighed for the calculation of immune organ indexes. The results showed that high and middle dosages of Gan lian Yu ping feng powder given at the day before immunisation and 3 days after immunisation elevated not only the contents of IFN-γ, the antibody titers of ILT (P<0.01) and the immune organ indexes (P<0.05) significantly, but also reduced the contents of IL-4. There was a significantly different degree of enhancement in the content of IFN-γ, the antibody of ILT (P<0.01) and the immune organ index (P<0.05). The results indicate that Gan lian Yu ping feng powder effectively improves the immunity in chickens. PMID:24146504

    2016-07-01

    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

    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.

    Full Text Available We studied the reproductive characteristics of femaleAmblyoma variegatum in the laboratory. These included variations in engorgedweight, percentage body mass due to eggs, and quantity of eggs an engorgedfemale could lay. 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.
