Abstract

The standard, in vitro, minimal inhibitory concentrations (MICs) of 5 antimicrobials; chloramphenicol, ciprofloxacin, enrofloxacin, norfloxacin and nalidixic acid were evaluated against vibrios isolated from diseased black tiger shrimps Penaeus monodon. One hundred and ninety-seven pathogenic vibrio isolates obtained from different shrimp culture areas in Thailand during March 2001-January 2002 were, V. fluvialis (50 isolates, 25.38%), V. damsela (41 isolates, 20.81%), V. vulnificus (39 isolates, 19.80%), V. parahaemolyticus (28 isolates, 14.21%), V. cholerae (25 isolates, 12.69%) and V. alginolyticus (14 isolates, 7.11%). MICs were examined for all the tested antimicrobials and the degree of susceptibility of shrimp vibrio pathogens to each product was analysed by determining their MICs. The investigation revealed that most of the tested isolates were susceptible to enrofloxacin,
chloramphenicol, norfloxacin and ciprofloxacin. Less than 50% of the isolates were susceptible to nalidixic acid.
