Occurrence of O / 129 sensitive and polymyxin B resistant Flavobacterium and penicillin sensitive Pseudomonas in the coastal waters of Cochin

Abstract

About 145 bacterial isolates from the coastal waters of Cochin were tested for their sensitivity to penicillin, polymyxin B and 0/129(2-4 diarnino 6-7 diisopropyl pteridine). Penicillin sensitive Pseudomonas (9.5%), penicillin resistant Moraxella (7.8" ,B). polymyxin B resistant Fluvobacterium ( 14.3%). and 0/129 sensitive Flavobacterium(57%) strains of bacteria were found. Occurrence of such bacterial istilates with variations in their reaction to antibiotics hinders their identification by the schemes proposed earlier.
