Objective:The study was conducted to determine the prevalence of infectious diseases in Sonali chickens at Bogra Sadar Upazila, Bogra, Bangladesh. Materials and methods: A total of 258 sick and dead Sonali chickens were examined for the diagnosis of different infectious diseases based on history, clinical findings and postmortem lesions of dead and sacrificed birds. Results: Infectious Bursal disease (IBD) was recorded in 14.72% (n=38/258) cases. Similarly, Newcastle disease (ND), Coccidiosis, Colibacillosis and Mycoplasmosis were recorded in 11.24% (n=29/258), 13.95% (n=36/258), 14.72% (n=38/258), 12.79% (n=33/258) cases, respectively. Mixed infection of IBD, ND and Coccidiosis found in 16.67% (n=43/258) birds. On the other hand, mixed infection of IBD, ND and colibacillosis was recorded in 15.89% (n=41/258) cases. Conclusion: It is concluded that several infectious diseases are commonly present in Sonali chicken in the study area of Bangladesh. Mixed infections are more prevalent as compared to single infection. Proper hygienic management and appropriate vaccination should be taken in consideration for effective control the diseases. Further microbiological and molecular diagnoses are suggested for detail studies of these diseases and their pathogens.

This study was conducted to estimate the proportional prevalence of clinical diseases and conditions in pet animals (dog, cat, and rabbit) attended at S. A. Quaderi Teaching Veterinary Hospital, Chittagong Veterinary and Animal Sciences University (CVASU), Chittagong, Bangladesh. A total of 388 cases of different clinical diseases and conditions were recorded during the study period from October 2016 to January 2017. Among them the overall proportional prevalence of clinical diseases and conditions in dog, cat and rabbit were 44.32%, 34.28% and 21.39% respectively. The medicinal case comprises the highest percentage of diseases as 79.07% and 66.92% in dog and cat, respectively. Among the medicinal cases parasitic diseases were most frequently encountered both in dog (24.42%) and cat (23.31%). Whereas, prevalence of surgical cases were 16.28% in dog and 31.58% in cat and gynecological cases were 4.65% in dog and 1.50% in cat. In rabbit, prevalence of traumatic injuries and fractures were 16.87% followed by mange 12.06%. The parasitic cases were highest in all of the clinical diseases and conditions. So, proper prevention and therapeutic management should be taken to reduce the prevalence of parasitic diseases of pet animals. Immunoprophylaxis or vaccination and hygienic management should be performed to curb the infectious diseases. Further extensive epidemiologic, laboratory or molecular studies are also needed for the appropriate prevention and control measures of diseases and conditions of pet animals in study area.

The study was conducted to determine the prevalence of clinical diseases and disorders in goats at Jhenaidah Sadar upazilla, Jhenaidah, Bangladesh. A total of 120 sick goats were examined during the period from September to November, 2015. The presumptive diagnosis of the diseases was performed on the basis of history, owner’s complaints, clinical findings and physical examination of patients. Among the diseases and disorders, parasitic infestation 34 (28.33%) case were highest in all cases. On the other hand, non specific fever 25 (20.83%), anorexia 14 (11.67%), peste des petits ruminants (PPR) 10 (8.33%), Gid disease 3 (2.5%), Diarrhea 5(4.17%), Myiasis wound 7(5.83%), Bloat 4(3.33%), Navel ill 2(1.67%), Pneumonia 7(5.83%), Vitamin and mineral deficiency 4(3.33%) and Dystocia 5(4.17%) were also recorded. It was also reported that adult (62.5%), female (66.67%) and Black Bengal goats (89.16%) were showed more susceptible to diseases than young (37.5%), male (33.33%) and Jamunapari (10.83%) goats. These results of the study might be helpful to develop effective prevention and control strategies against diseases and disorders in goats. Asian Australas. J. Biosci. Biotechnol. 2017, 2 (1), 45-50
