Potential virulence and antimicrobial susceptibility of Aeromonas popoffii recovered from freshwater and seawater

Abstract

Aeromonas popoffii is the most recent species within the genus Aeromonas described from freshwater. In our study this species was also recovered from this habitat and for the first time from seawater. Most of the virulence factors known in Aeromonas spp. (aerolysin/hemolysin, serine protease, lipases and DNases) were highly prevalent in this species. Third-generation cephalosporins and quinolones were the most active antimicrobial agents against A. popoffii.
