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.
