Studies concerning the hemagglutinant activity of some pathogenic and opportunistic pathogenic strains of genus Vibrio.

Abstract

1606 bacterial strains, belonging to Vibrio genus (189 V. cholerae 0 : 1; 1091 V. cholerae nongroup 0 : 1 and 205 V. halophilic strains) of different sources of isolation, were studied, concerning their hemagglutinating behaviour to 5 different animal red blood cells (human, bovine, chicken, African green monkey and guinea pig) in mannose/fucose presence/absence. The study aimed to establish the spectrum of their hemagglutinating activity as well as any possible correlation between the source of isolation, serogroup etc and the HA-type/subtype. Mannose/fucose sensitive as well as mannose/fucose resistant hemagglutinins were exhibited by the different tested strains. As unknown behaviour, a noticeable hemagglutination only in the carbohydrate presence was recorded. The HA-types and subtypes in 861 V. cholerae nongroup 0 : 1 tested strains are presented.
