Pathogenicity of 42-44 Mdal plasmid positive and negative Yersinia pseudotuberculosis I and Yersinia enterocolitica 0:8 and 0:9 studied in the guinea pig eye model (Serény test).
When virulence plasmid (42-44 Mdal) positive and negative Yersinia pseudotuberculosis I and Yersinia enterocolitica 0:8 and 0:9 were tested in the guinea pig eye model the following order of pathogenicity was observed: Plasmid-positive Y. pseudotuberculosis I (death of the animal) greater than plasmid-negative Y. pseudotuberculosis I approximately equal to plasmid-positive Y. enterocolitica 0:8 (severe conjunctivitis) greater than plasmid-positive Y. enterocolitica 0:9 (mild conjunctivitis) greater than plasmid-negative Y. enterocolitica 0:8 and 0:9 (no effect).
