Abstract

Aeromonads are known to cause disease in cultured fish. Aeromonas sobria is a major fish pathogen and also possesses the zoonotic potential to cause a variety of diseases in humans. The current study reported Aeromonas sobria SB16 from the integument, gut, and kidney of seven rainbow trout among eleven diseased fish, depicting the presence of A. sobria in about 64% of the examined fish. The association of Aeromonas sobria was found to be higher in integument (65.38%), followed by gut (27.88%), and kidney (6.73%). Biochemical tests performed on the isolate showed positive reactions to citrate, ornithine, nitrate, TDA, and lysine. Morphological and 16S rRNA gene sequencing identified the isolated strain as Aeromonas sobria. The study is the first report of Aeromonas sobria in Rainbow trout from Kashmir valley, India. The occurrence of this known pathogenic microorganism from various organs of O. mykiss is interesting and needs further research to investigate its epidemiology, pathogenicity, and possible interactions with the host.
