Description: Yersinia. This genus consists of 11 species, 3 of which are human pathogens. Specific virulence factors are encoded within pathogenicity islands (PAIs) that are required for the invasive phenotype associated with Yersinia infections. These PAIs may be carried on extrachromosomal plasmids or on the chromosome. One key virulence plasmid contained by the three human-specific pathogens is pCD1/pYv, which encodes a type III secretion system for the delivery of virulence proteins that contribute to internalization into the host cell. Yersinia kristensenii. Yersinia kristensenii is one of several species formerly classified as Yersinia enterocolitica-like bacteria. This organism has been isolated environmental samples, food, animals and sick and healthy humans.
