Identification, isolation and in vitro antimicrobial susceptibility testing of Aeromonas veronii associated with an acute death of Channel Catfish (Ictalurus lunetas) in China

Abstract

Aeromonas veronii is a common pathogen in both humans and animals. It exists in the environment we live. Many reports showed it could lead to human infection but few demonstrated its effect on aquatic animals, especially Channel Catfish (Ictalurus lunetaus). Here, A. veronii was isolated from an acute death case of Channel Catfish in Southwestern China. This Gram-negative bacillus was identified by 16S rRNA sequencing. Antimicrobial susceptibility was also conducted to guide the treatment of the disease.
