Yersinia enterocolitica palearctica serobiotype O:3/4--a successful group of emerging zoonotic pathogens.

ABSTRACT:

Background

High-pathogenic Y. enterocolitica ssp. enterocolitica caused several human outbreaks in Northern America. In contrast, low pathogenic Y. enterocolitica ssp. palearctica serobiotype O:3/4 is responsible for sporadic cases worldwide with asymptomatic pigs being the main source of infection. Genomes of three Y. enterocolitica ssp. palearctica serobiotype O:3/4 human isolates (including the completely sequenced Y11 German DSMZ type strain) were compared to the high-pathogenic Y. enterocolitica ssp. enterocolitica 8081 O:8/1B to address the peculiarities of the O:3/4 group.

Results

Most high-pathogenicity-associated determinants of Y. enterocolitica ssp. enterocolitica (like the High-Pathogenicity Island, yts1 type 2 and ysa type 3 secretion systems) are absent in Y. e
