A cross-sectional study was conducted to investigate the prevalence and antimicrobial resistance pattern in Salmonella from 108 rectal swab of stray dogs of 9 randomly selected areas of Chittagong Metropolitan Area. Rectal swabs were collected for isolating Salmonella enterica serovar Typhimurium through bacteriological culture and InvA specific PCR assay followed by antimicrobial susceptibility testing. Out of the 108 samples, females showed higher prevalence (66.67%) than males (58.93%). Among the 67 bacterial culture positive isolates, 10.45% was Salmonella Typhimurium in InvA gene specific PCR. Isolated Salmonella was tested for resistance to twelve different antimicrobial agents, using disc diffusion method. In cultural sensitivity test, 100% resistance was found against Amoxicillin where higher resistance was found against Azithromycin, Cefixime, Ampicilin and Pefloxacin. Gentamycin and Colistin appeared to be sensitive. Multidrug resistance of Salmonella spp. has increased with a great deal in developing countries in the last decades. In this study, most of the Salmonella isolates were multidrug resistant. Rational use of antibiotics needs to be adopted in clinical practice to prevent the emergence of multi-drug resistance Salmonella and their zoonotic transmission.

The study was carried out to record all clinical cases of dog bites in different livestock species at two internship placements in India during October to November and Bangladesh during July to September 2012. The study aimed to determine the proportionate prevalence of suspected rabies in livestock species, frequency of observed clinical signs and the therapeutic management of dog bites. A structured record keeping sheet was used to obtain the necessary information. The prevalence of suspected rabies in cattle was 38% and 3.5% each in goat and horse respectively. The prevalence of rabies in non-vaccinated animal was 84.6%. Female cattle had higher suspected rabies cases (24.1%) than male cattle. 51.7% dog bites were managed by washing the biting site with alkaline soap followed by dressing the wound with either antiseptic or antibiotic powder. Postexposure vaccines were used in 24.1% cases. Strict adherence to vigorous wound washing and immediate medical evaluation after animal bites will prevent the development of Animal rabies. Veterinarians and animal control officers should handle potentially rabid animals with extreme caution.
