Studies on aerolysin and a serine protease from Aeromonas trota sp. nov

Abstract

Hybridization of 257 mesophilic aeromonads revealed that the aerolysin gene is present in virtually all strains irrespective of origin of isolation. A probe comprising the promotor region was specific for a species now defined as Aeromonas trota sp. nov. Finally, isolation of a serine protease that is concomitantly expressed with aerolysin is described.
