Pathogenicity and virulence of Aeromonas schubertii in farmed Asian seabass (Lates calcarifer) in Thailand.

ABSTRACT:

Background

Aeromonas schubertii, an emerging pathogen primarily recognized in humans, shrimps, and other mammals, is increasingly implicated in aquatic animal diseases. Despite its growing prevalence, reports of its involvement in fish diseases are limited. This study investigates a natural outbreak of A. schubertii associated with high mortality in cultured Asian seabass (Lates calcarifer) in Thailand and suggest its potential pathogenicity in cultured fish species.

Results

To investigate the cause of mortality in Asian seabass at a commercial farm in central Thailand, two A. schubertii isolates-CHULA2021a and CHULA2021b-were recovered from moribund and dead juvenile fish. Naturally infected fish exhibited lethargy and slow swimming behavior, without any visible external le
