PREVALENCE AND ANTIBIOTIC SENSITIVITY PATTERNS OF SALMONELLA SPP. IN HOUSEHOLD CATS IN DIFFERENT AREA OF DHAKA CITY

Abstract

This study was conducted to isolate, identify and antibiotic profiling of Salmonella spp. harbors in cat, which are raised as household pets at Dhanmondi, Mohammadpur, Mirpur and Agargaon in Dhaka city. A total of 40 fecal samples were collected from Vet and Pet Care Clinics to carry out this study. All samples were collected aseptically and inoculated onto various culture media for isolation of bacteria. Identification of bacteria from positive samples were performed by cultural characteristics, Gram’s staining and biochemical tests. The overall prevalence of Salmonella spp. in fecal samples in cats were found 53%. The study was conducted according to breed, sex, age and area basis where the most prevalence of Salmonella were found between 1 to 3 years of age (75%). Agargaon and Mohammadpur areas were subjected to most Salmonella infected area (60%). Antibiotic sensitivity profiling of the isolated Salmonella spp. was performed by the disc diffusion method against 10 randomly used antibiotics. The highest rate of sensitivity against Salmonella was found with Ceftriaxone (77%) and Ciprofloxacin (72%) followed by Cefuroxime (67%), Amoxicillin + Clavulanic Acid (67%), Cotrimoxazole (53%), Cefixime (52%) and Gentamycin (48%). The highest rate of resistance was recorded to Amoxicillin (57%) and Cefuroxime (43%). Among the areas, the most sensitive of Salmonella was found in Dhanmondi (60%) and Mirpur (56%). The drug resistance of Salmonella spp. among Mohammadpur (28%), Agargaon (25%), Mirpur (20%) and Dhanmondi (17%) area were observed in this study. Data from this study suggest that domestic cats carry multi-drug resistant against Salmonella spp. which can be transferred to humans through direct contact or the food chain and can cause a potential public health hazard.
