Abstract
Eighteen strains of Aeromonas hydrophila from patients with bacteraemi a were investigated for possible virulence factors. Cytotoxin and haem olysin were produced by all strains, whereas cholera toxin-like factor was produced by 33% of strains only. Enterotoxin production was not d etected. Haemagglutination of guinea-pig, fowl and rabbit erythrocytes was demonstrated by 83%, 67% and 61% of strains, respectively. Fucose - and mannose-sensitive haemagglutinins were predominant. None of the strains agglutinated sheep erythrocytes. Extrachromosomal DNA was dete cted in 17 strains, 16 of which had a plasmid(3.6-5.1 MDa), the majori ty being between 4.6 and 5.1 MDa.
