University of Tehran Press Journal of Veterinary Research 2008-2525 55 2 2000 07 22 - - 16719 FA Journal Article 1970 01 01 To study the role of Vibrio bacteria as probable agents associated with currently occurence of mortality in farmed prawn of Heleh station in Busher, 215 moribund or freshly dead Peneaus indicus (94 samples) and P. semisulcatus (70 samples) were obtained from 10 reared ponds. The bacteriological examination resulted in isolation and identification of 164 isolates of Vibrio consisting of V. parahaemolyticus (29.2 %), V. harveyi (21.9 %), V. alginolyticus (21.9 %), V. anguillarum (9.75 %) and Vibrio sp, (17 %). These bacterial isolates were sensitive to chloramphincol, cephalotin and oxytetracycline but not to ampicilin and penicilin.
