Prevalence and Antimicrobial Susceptibility of Pathogenic Bacteria in Nile Tilapia, Oreochromis niloticus L

Nile tilapia, Oreochromis niloticus, is one of the most popular aquaculture fi sh species in the world. However, among several challenges, the presence of pathogenic bacteria causes high economic losses. Thus, the main objective of this study was to isolate and identify the potent bacterial pathogens from Nile tilapia reared at Hawassa Fish Research and Multiplication Station, Ethiopia. For this, infected fish samples were collected from the research station and subjected to microbiological and biochemical tests.
