K. Rajeshwari* and L. D. Devasree

ABSTRACT

The present research work were aimed for collection, screening and identification of bacterial species from infected ornamental fishes and estimate the biochemical characterization and DNA quantity of predominated microbes from experimental fishes. The various bacterial species were detected. The bacterial species such as Pseudomonas aeruginosa, Pseudomonas fluorescence, Vibrio cholerae, Vibrio vulnificus, Salmonella sp. Enterobacter E. coli and Aeromonas sp. were isolated from the experimental fishes. The results of this present work, concludes that the ornamental fishes from Madurai district indicate that the pathogenic bacteria species were abounded in the aquarium. The presence of bacteria of definite economic importance is also reported in this study on pathogens distribution in aqua farms.
