ISOLATION OF BACTERIA FROM TILAPIA FISH (Oreochromis nilotica)

ISOLATION OF BACTERIA FROM  TILAPIA FISH (O.nilotica)

Abstract

The present study was conducted to isolate, culture and identification (by gram staining) of bacteria from diseased fish Tilapia (  Oreochromis  niloticus).In the present study, monthly prevalence and abundance of the pathogenic bacteria were studied.The host Tilapia (Oreochromis niloticus) harbored different types of bacteria .Bacteria are found in different parts of the body. Such as: -ulcerative lesions, gills, intestine, kidney etc. The highest prevalence of bacteria in Tilapia (Oreochromis niloticus) was found in the month of March (80%) and lowest in the month of October (20%).The out break of EUS syndrome has been occurring by the bacteria during the period from November to March.  E. coli ;Aeromonas hydrophila ; Aeromonas fungatum ;   Aeromonas veronii ;Aeromonas salmonicida ;Aeromonas jandaei ;Seudomonas anguiliseticus ;Staphylococcus epidermatis ;Klebsiella sp are isolated from the ulcerative fish. But which is the causal agent of EUS can not be specifically identified. (Kar et al, 1999b).
