Kn. Majeed et Ic. Macrae, CYTOTOXIC AND HEMAGGLUTINATING ACTIVITIES OF MOTILE AEROMONAS SPECIES, Journal of Medical Microbiology, 40(3), 1994, pp. 188-193
Cytotoxic and haemagglutinating properties were determined in 114 Aero
monas strains isolated from various sites in slaughtered lambs and fro
m processed lamb meat. Cytotoxic activity on Vero cells was observed i
n 48 (42 %) of the strains. It was more common in A. sobria and A. hyd
rophila isolates than with A. caviae isolates. Haemagglutination (HA)
activity was found frequently in motile aeromonads irrespective of spe
cies; it was present in 50 % of A. sobria strains, 51 % of A. hydrophi
la strains and 48 % of A. caviae strains. HA was inhibited by fucose,
galactose and mannose at low concentration and, in most cases, two or
three of these sugars were inhibitory. A significant association was f
ound between certain HA-inhibition patterns and the production of cyto
toxin by Aeromonas spp.
