title: Aeromonas hydrophila septicaemia in a grey seal (Halichoerus grypus) from the Baltic Sea: a case study.
abstract: Aeromonas hydrophila septicaemia in a grey seal (Halichoerus grypus) from the Swedish part of the Baltic Sea is reported. The pathogen was isolated from both lung and spleen specimens. All of the A. hydrophila isolates produced haemolysin and Vero active cytotoxin. The aerolysin gene was found in all tested isolates as evidenced by the polymerase chain reaction (PCR) technique. Also, all isolates tested showed identical patterns of biochemical and antibiotic resistance. As Aeromonas spp. commonly occur in aquatic environments, we suggest that organisms from this genus may also play an important role as opportunistic pathogens in morbillivirus infected seals.
