Effect of organizational climate upon the job performance of instructors’ physical education

Propose: The current study was conducted to examine the effect of organizational climate on the Job Performance of Instructors’ Physical Education. Material: A quantitative method was employed for this purpose; a survey research design was used. There was 169 Instructors’ Physical Education preferred through stratified sampling technique. A structured questionnaire was administered to collect the data. The data was analyzed using inferential statistics (linear and multiple regression). Results: The results of the study indicated that organizational climate affect job satisfaction significantly. All the dimensions of organizational climate contribute to increasing the Instructors’ Physical Education performance. Conclusion: The current study concluded that Instructors’ Physical Education not only feel comfortable in a healthy organizational climate but also increase their level of performance. The study also depicted that effective communication structure, reward system, teamwork, career development, and effective planning and decision making strategies are the valuable ingredients to enhance the performance of Instructors’ Physical Education. Recommendation: Keeping in view the results of the current study, it is recommended that head of the institution may focus or promote supportive culture in their respective educational institutions to enhance the performance of instructors’ physical education

Microsatellite based genetic variation among the buffalo breed populations in Pakistan

Introduction: Eight microsatellite loci were used to define genetic diversity among five native water buffalo breeds in Pakistan. Material and Methods: Blood samples (10 mL) from 25 buffaloes of each of the Nili, Ravi, Nili-Ravi, Kundhi, and Azi-Kheli breeds were collected aseptically from the jugular vein into 50 ml Falcon tubes containing 200 µl of 0.5 M EDTA. The phenol-chloroform method was used to extract DNA and the regions were amplified for microsatellite analysis. The eight microsatellite markers ETH10, INRA005, ILSTS029, ILSTS033, ILSTS049, ILSTS052, ETH225, and CSSM66 were analysed. Results: The effective number of alleles across all loci was as usual lower than the observed values with a mean value of 2.52 alleles per locus. The overall allele frequency varied from 0.0041 for alleles B, I, and J over respective loci ILSTS052, INRA005, and ILSTS029 to 0.80 for allele H over locus ILSTS029. The average observed and expected heterozygosity values across all polymorphic loci in all studied buffalo breeds were 0.43 and 0.53, respectively. The overall value for polymorphic information content of considered microsatellite markers was 0.53, suggesting their appropriateness for genetic diversity analysis in buffalo. The mean Fis value was 0.13 and all loci except ILSTS049 were found significantly deviated from HWE, most likely due to nonrandom breeding. The five buffalo populations were genetically less diverse as indicated by a small mean Fst value (0.07). The average gene flow (Nm) indicative for population migration was calculated as 3.31. Nei’s original measures of genetic distance (Ds) revealed ancient divergence of the Nili and Azi-Kheli breeds (Ds = 0.1747) and recent divergence of the Nili and Ravi breeds (Ds = 0.0374). Conclusion: These estimates of genetic diversity were seen to coincide with phenotypic differentiation among the studied buffalo breeds. The present study reports the first microsatellite marker-based genetic diversity analysis in Pakistani buffalo breeds, and might facilitate similar studies in other livestock breeds of Pakistan

Interaction of infectious bursal disease virus with the immune system of poultry

Immune dysfunction can be either at the humoral or cellular levels and is mediated by a myriad of factors including virus-induced immunosuppression. Infectious bursal disease virus (IBDV) affects domesticated poultry and causing health problems mainly due to prolonged immunosuppression. Destruction of the immunoglobulin-producing cells is the principal cause of IBDV-induced immunosuppression, which leads to significant impairment of the primary antibody responses. Due to these effects, IBDV infection not only increases the susceptibility of poultry to other viral infections but predisposes the host to several other bacteria of variable pathologies. The IBDV-induced immune-suppression is well-known phenomenon, however, recently there have been significant advancements in understanding the molecular mechanisms of this immune-suppression. This review discuss current updates regarding the immunotoxic and immunosuppressive nature of IBDV in the poultry and highlights areas requiring future research attentions that may help to establish foundations for effective and improved vaccines against IBDV
