Veterinary Immunology and Immunopathology | Year: 2016
Campylobacter jejuni (C. jejuni) is the most frequently reported bacterial food-borne pathogen. Poultry is regarded to be the main reservoir for human campylobacteriosis. By some authors C. jejuni is considered as a commensal of the chicken gut, but clinical signs may be observed indicating host-pathogen interaction. Little is known about C. jejuni strain dependent differences in stimulation of the immune response in chicken. Therefore we investigated the colonization pattern as well as humoral and cell-mediated immune parameters in three-week old specific pathogen-free (SPF) layer-type (LT) chicken after inoculation with different human and avian derived C. jejuni isolates between three and 21 dpi. In a subsequent experiment we investigated earlier time points and additionally compared commercial broilers with SPF-LT chicken to identify possible differences after inoculation of selected C. jejuni strains from prior experiments. No clinical symptoms were observed during the experiments. The colonization pattern did not correlate with the strain origin or magnitude of circulating C. jejuni specific antibodies. Only minor changes were observed in caecal T cell populations after C. jejuni inoculation compared to non-inoculated controls. Interestingly the mRNA expression of IL-6 and IFN-gamma was down regulated at some time points after inoculation suggesting a possible immunomodulatory effect of some C. jejuni strains in the gut. Furthermore, broilers were colonized to a higher extend and the local immune cell response was different compared to the SPF -LT birds indicating an influence of genotype on C. jejuni colonization pattern.Overall, our study demonstrates that the outcome of C. jejuni infection in chicken is influenced by genotype and partially by the C. jejuni isolate, leading to differences in the early immune response and thereafter the control of colonization and infection. © 2015 Elsevier B.V..

Contents: This study was conducted to evaluate the response of Bali bulls (Bos javanicus) to different semen collection methods and their effects on fresh and post-thawed semen quality. The collection methods employed were electro-ejaculation (EE), transrectal massage (RM) and RM followed by EE (RM + EE). A total of 25 untrained Bali bulls (age between 2 and 4 years old) were subjected to the different semen collection methods. Fresh semen samples from all the 25 bulls were evaluated for volume, pH, general motility, live/dead ratio and abnormality using the conventional method. For fresh and frozen samples collected by EE and RM from 10 bulls, computer-assisted semen analysis system was used for precise quantitative measurement of motility, velocity and forward progression. Accucell photometer was used to measure sperm concentration in all samples, regardless fresh and frozen. Semen samples were obtained 100% of the attempts using EE, 84% using RM and 96% using RM + EE. There were no differences among the collection methods for fresh semen quality characteristics, including motility, morphology and viability, but pH and volume were higher for EE than RM and RM + EE. Higher sperm concentration was observed in semen collected by RM than the other two methods. Different age groups (2-3 and >3-4 years old) of the bulls did not show significant differences in volume, pH, sperm concentration, percentages in motility, live/dead ratio and normal sperm morphology. The quality of semen for general and progressive motility, VAP, VSL and VCL and acrosomal integrity after thawing was higher for RM than EE. In conclusion, Bali bulls appeared to respond best to EE and the combination of RM + EE than RM, as a method of semen collection, with a shorter time of stimulation required. Differences in age of the Bali bulls did not affect the semen quality. © 2013 Blackwell Verlag GmbH. Source

Superovulation has become a common assisted reproductive technology in the field of animal reproduction. In addition, zona-free hamster oocytes have been used in heterologous in vitro fertilization research to evaluate sperm function. A study was conducted to compare eight different superovulation protocols for golden hamsters using two concentrations of human Chorionic Gonadotropin (hCG) given at two time intervals post-pregnant mare's serum gonadotrophin (PMSG) injection and two time intervals of oocyte harvesting. Fifty-six female golden hamsters were randomly and equally assigned into eight superovulation groups. Hamsters were superovulated initially with PMSG followed by human Chorionic Gonadotrophin (hCG). All the groups received 40 IU PMSG, either 40 or 45 IU hCG given at either 48-50 or 55-57 h post PMSG injection and the oocytes recovered at either 12-15 or 16-18 h after hCG injection. Higher number of recovered oocytes (51.57±0.83) and maturation rates (94.20%) (p<0.05) were detected in hamsters which received 45 IU hCG at 55-57 h after PMSG injection when the oocytes were recovered later at 16-18 h compared with hamsters in the other groups. Mean fertilization rate of hamsters given 45 IU hCG at 55-57 h post PMSG injection ranged from 77.89-78.84% and were significantly higher (p<0.05) than those that received hCG at 48-50 h post PMSG injection. In conclusion administration of 40 IU PMSG followed by 45 IU hCG injection at 55 and 57 h post PMSG injection followed by oocyte recovery after 16-18 h gave the highest response in oocyte recovery and maturation in golden hamsters. © 2013 Academic Journals Inc.

The genetic diversity of native chicken populations from Myanmar, Thailand, and Laos was examined by using 102 insertion and/or deletion (indels) markers. Most of the indels loci were polymorphic (71% to 96%), and the genetic variability was similar in all populations. The average observed heterozygosities (HO) and expected heterozygosities (HE) ranged from 0.205 to 0.263 and 0.239 to 0.381, respectively. The coefficients of genetic differentiation ( Gst) for all cumulated populations was 0.125, and the Thai native chickens showed higher Gst (0.088) than Myanmar (0.041) and Laotian (0.024) populations. The pairwise Fst distances ranged from 0.144 to 0.308 among populations. A neighbor-joining (NJ) tree, using Nei's genetic distance, revealed that Thai and Laotian native chicken populations were genetically close, while Myanmar native chickens were distant from the others. The native chickens from these three countries were thought to be descended from three different origins ( K = 3) from STRUCTURE analysis. Genetic admixture was observed in Thai and Laotian native chickens, while admixture was absent in Myanmar native chickens. Copyright © 2015 by Asian-Australasian Journal of Animal Sciences Source

Most parasitic zoonoses are neglected diseases despite causing a considerable global burden of ill health in humans. A review of available literatures indicates that many parasitic zoonoses are endemic in neighbouring countries of Myanmar. However, the information on zoonotic parasitic diseases in Myanmar is very limited. The prevalence of some parasitic zoonoses in livestock of Myanmar and its neighbouring countries has been highlighted in this review. Prevention and control programs against sources and reservoirs of parasitic zoonoses and other zoonoses should be planned by public health and veterinary officers based on reliable information from systematic surveillance. © 2015 Academic Journals Inc.
