H. Fukushima et al., GENETIC-VARIATION OF YERSINIA-ENTEROCOLITICA SEROTYPE-0 9 STRAINS DETECTED IN SAMPLES FROM WESTERN AND EASTERN-COUNTRIES/, Zentralblatt fur Bakteriologie, 288(2), 1998, pp. 167-174
We made use of H-serotyping, ribotyping and restriction endonuclease a
nalysis of virulence plasmid DNA (REAP) to differentiate Yersinia ente
rocolitica serotype O:9 strains. A close correlation between ribotypes
/REAP patterns and the geographical and chronological distribution of
serotype O:9 strains was apparent. In European countries, variant clon
es of serotype O:9 have rapidly increased among humans and swine since
the late 1980s.
