Toxigenicity and drug sensitivity of vibrio mimicus isolated from fresh water prawns in Bangladesh

Abstract

Eight isolates of Vibrio mimicus from 20 prawns (Macrobrachium malcolmsonii) obtained from fresh water in Bangladesh were tested for enterotoxin production and antibiotic sensitivity. Six of the eight isolates (75%) induced fluid accumulation in rabbit ileal loops. AN isolates were resistant to kanamycin and streptomycin and sensitive to chloramphenicol, gentamictn and trimethoprim-suffame-thoxazole; 75% were sensitive to ampicilfin. The proportion of isolates producing toxin of all isolates and their pattern of sensitivity to antimicrobial drugs resembled human isolates of V mimicus.
