Abstract

Out of 326 total bacterial isolates from infected freshwater and marine fishes
having no history of either prophylactic or therapeutic use of antibiotics, 145
were identified atleast upto genus level. The predominanting genera were
Aeromonas, Pseudomonas, Vibrio, Acinet,obacter, Enterobacter, Alcaligenes,
Plesiomonas, Edwardsiella, Staphylococcus and Nocardia. In this study 88 of
the identified bacteria belonging to 10 genera were tested for resistance pattern
against 26 different antibiotics by disc diffusion method in Muller-Hintor agar.
The resistance level against streptomycin, penicillin and ampicillin was
exhibited by more than 60 per cent of the bacteria and oxytetracycline was
most effective in commonly used tetracycline group of antibiotics. None of the
isolates was sensitive to all the 26 antibiotics, whereas resistance in any single
isolate was found to be against a maximum of 14 antibiotics. Abundance of
natural single and multiple antibiotic resistance was demonstrated to be upto
the upper limit of 3.7 and 97.1 % respectively. The situation appears to be
alarming as this antibiotic resistance gene pool could be a potential threat to
humans and therefore is of public health significance.
