Abstract
Fourteen antibacterial agents belonging to 9 different groups of
antibiotics viz. aminoglycosides, cephalosporins, nitrofurantoin,
fluroquinolones, chloramphenicol, sulphonamides, tetracyclines,
penicillin and polymixin were used for in vitro sensitivity
testing of eight isolates of Aeromonas hydrophila isolated from
fifteen samples of fish, collected from retail shops in Mhow
city. The sensitivity (100%) was attributed to ciprofloxacin,
cefuroxime, ceftriaxone, cephotaxime, chloramphenicol,
gentamycin, kanamycin, nitrofurantoin, nalidixic acid and
ofloxacin followed by Co-trimoxazole (62.2%) and oxytetracycline
(50%). All the isolates were resistant to ampicillin and
colistin antibiotics. That means, none of the isolates were
found to be sensitive for penicillin and polymixin group of
antibiotics. Multiple drug resistance was also observed in all
A. hydrophila isolates.
