[Phylogeny, pathogenicity and genetic diversity of Yersinia enterocolitica].

The past decade has witnessed a significant expansion of knowledge in field of Y. enterocolitica pathogenicity and virulence. In this period, a change of high-pathogenicity Y. enterocolitica bioserotype 1B/O8 geographical distribution has been observed. In 2003, Y. enterocolitica 1B/O8, major representative ofAmerican lineage, emerged in Europe, where it prevails in Poland. Complete genomes of major pathogenic bioserotypes have been made available, triggering substantial advances in genotyping and phylogeny of Y. enterocolitica. This study attempts to bring together the novelty in field of Y. enterocolitica pathogenicity and molecular epidemiology to rise the interest in the field, and to encourage further studies to better understand epidemiology ofyersiniosis in Poland.
