Examination of virulence and the effects of environmental conditions on the growth of Aeromonas hydrophila in farmed tilapia and histopathological changes in infected fish

Abstract

The study aims to examine the pathogenicity, the effects of environmental conditions on the growth of Aeromonas hydrophila in tilapia, and histopathological changes in infected fish. A. hydrophila isolates, which were recovered from diseased tilapia samples collected at farming cages/ponds in several northern Vietnam provinces, were identified by biochemical tests, PCR confirmation, and sequencing of 16S rRNA and housekeeping genes (gyrB)...
