Microbial Flora from the Epizootic Ulcerative Syndrome (EUS) Infected Murrel Channa striatus (Bloch, 1797) in Tirunelveli Region.

The microbial flora of the liver, gills, intestine, and muscle of epizootic ulcerative syndrome (EUS) infected murrel Channa striatus in Tirunelveli, Tamilnadu was estimated quantitatively and qualitatively, and the isolates were identified at genus and species level. Total viable microbial count was measured as highest range in gills (5.9 ± 0.5 x 10^7 CFU (colony forming units) g^-1) and lowest range in intestine (8.7 ± 1.8 x 10^4 CFU g^-1). In total 17 bacterial and mycotic species were isolated and identified and Aeromonas hydrophila, Enterobacter sp., Vibrio sp., Pseudomonas sp., Escherichia coli, Aphanomyces invadans, and Aspergillus sp. were the most predominant isolated and identified species in all samples. The purpose of this study is to isolate and identify the microflora of EUS infected C. striatus.
