PREVALENCE AND PROFILING OF ANTIBIOTIC SENSITIVITY OF A KEY PUBLIC HEALTH PLAYER ESCHERICHIA COLI FROM COMPANION ANIMAL IN DHAKA CITY

Abstract

This study was conducted in order to isolate, identify and to profiling the status of antibiotic sensitivity of the important public health organism Escherichia coli of companion animal. A total of 30 fecal samples of cats and dogs were collected from two different regions of Dhaka city, aseptically and inoculated onto various culture media for isolation of E. coli. The microorganisms were isolated and identified by performing cultural characteristics and biochemical tests. The study had been conducted based on species, age, location and gender of host species. The prevalence of E. coli infection in cat was 66.67% and in dog was 60.00%, respectively with same ratio of resistance in male and female in dog whereas in cat female were more resistance than male. To perform the disc diffusion method for profiling the antibiotic sensitivity, 10 commonly used antibiotics were used. The highest rate of resistance was recorded in Metronidazole (57.89%) and Amoxicillin (52.63%) followed by Co-trimoxazole (41.10%), Ciprofloxacin (31.57%), Ceftriaxone (31.57%) and Azithromycin (26.31%). The highest rate of sensitivity was recorded to Cefixime (52.63%) followed by Ciprofloxacin (36.84%), Cefuroxime (36.84%) and Gentamicin (36.84%). Data from this study reveal that companion animal like cat and dog carry multi-drug resistant E. coli sp. which can be transferred to human and can cause a public health hazard.
