Different food samples collected from randomly selected retail consumer shops in Uppsala (Central Sweden) were investigated for the presence of Aeromonas species. Forty-two percent (10/24) of the food samples contained organisms belonging to two Aeromonas spp. namely, Aeromonas hydrophila and Aeromonas sobria. The type of foods from which Aeromonas were isolated, were poultry, fish, beef and pork. None of the Aeromonas spp. were isolated from vegetables or raw milk samples. The Aeromonas isolates possessed the capacity to produce different potential virulence determinants such as haemolysin, cytotoxin, cytotonic toxin, enterotoxin and protease. Since A. hydrophila and A. sobria are considered to be potential human pathogens, it is concluded that in case foodborne infections are suspected or encountered, the role of Aeromonas should not be ruled out. |
