ANTIBIOGRAM OF ESCHERICHIA-COLI ISOLATED FROM DIARRHEIC DOGS

Escherichia coli were isolated from 51 out of a total of 90 specimens examined from enteritis cases of dogs. The isolates were resistant to streptomycin, sulfadiazine and tetracyclines. They were invariably sus ceptible to 12 out of 17 anti-microbials tested and the susceptibility was on the high side to neomycin, co-trimoxazole, polymyxin-B. gentam icin and nalidixic acid. A judicious use of the antimicrobials is advo cated in the treatment of enteric and other infections of dogs with an aim to limit the emergence of resistant E. coli.
