Abstract

Bacterial flora associated with tail rot I fin rot of Carassius auratus,
Xiphophorus helleri and hemorrhagic ulcers of Clarias spp were studied.
Sensitivity pattern of 33 isolates comprising Aeromonas spp, Pseudomonas
spp and Gram-positive rods from diseased C. auratus, X. helleri and Clarias
spp were screened against six broad-spectrum antibiotics viz. ciprofloxacin,
chloramphenicol, co-trimoxazole, gentamycin, nitro-furantoin and
oxytetracycline. Ciprofloxacin was the most effective in inhibiting bacteria
at 0.05 - 0.10 p.g/ml level. About 44% of Pseudomonas spp. were resistant to
nitrofurantoin. Resistance to oxytetracycline was seen in 27% of Aeromonas
spp Gram-positive rods were comparatively more resistant to antibiotics.
The multiple antibiotic resistance was seen in 21% of the bacterial isolates
of diseased fish.
