[Relationship between the toxigenicity and ribotype distribution of Pseudomonas cocovenenans subsp. farinofermentans].
By rDNA fingerprinting technique, ribotype discrimination analysis was conducted for exploring the relationship between the toxigenicity and ribotype distribution of 42 strains of Pseudomonas cocovenenans subsp. farinofermentans. The results showed that 73.8 percent of the strains were toxigenic, which were distributed within the most ribotype and isolated from either food poisoning samples or normal food samples. The other strains were not toxigenic; which were isolated from normal food samples and distributed only within a few ribotypes. Since the most clones of P. cocovenenans subsp. farinofermentans were toxigenic, their potential hazard should be concerned.
