Assessment of virulence properties and characterization of Aeromonas

Aeromonas spp. were isolated from duckweed (DW), water and gills and intestinal contents of fish sampled from waste water and non-waste water areas of a fish farm. Percentage distribution of different species were: A. sobria (56.6%), A. hydrophila (28.0%) and A. caviae (15.8%). The density of Aeromonas spp. in gills significantly correlated (P
