The prevalence and characterization of pathogenic bacteria from
fish cultured in ponds fertilized with organic manures was studied.
Almost the same type of bacterial species were isolated from
organic manures, ponds water and organs of fish. Chicken manure
supported more bacterial species as proved by its high total
aerobic bacterial count than cow manure. Total aerobic bacterial
count differed significantly in different organs of fish in three
ponds except in case of liver. High prevalence of Aeromonas sp. was
found in all systems except in chicken manure treated pond, where
Pseudomonas sp. was higher in percentage. Water and organic manures
were the main source of Aeromonas sp, Bacillus sp. and Pseudomonas
sp. Chicken manure was source of Proteus sp. and Serratia sp. while
Serratia sp. was also isolated from cow manures. Zoonotic pathogens
isolated from fish are important from veterinary public health
point of view and a broad spectrum research is highly called for.
These bacteria cause diseases including haemorrhage, fin rot, skin
necrosis, chronic lesions on caudal fin, epizootic ulcerative
syndrome and septicaemia in fish.
