Abstract

Summary

The plasmid-encoded proteins of the pathogenic serogroups O3 and O8 were analysed with respect to their immunological relationship. Common epitopes on yersinia outer-membrane proteins (YOPs) and released proteins (RPs) were recognised by orally-induced antisera against living bacteria and by monospecific antisera induced against single RPs of serogroup O8. A major difference between the pathogenic serogroups O3 and O8 was YOP42, which was detected only in the outer membrane of the highly pathogenic O8 bacteria. The YOP42 may be responsible for the greater virulence of serogroup O8 bacteria.
