초록
Yersinia enterocolitica is an important foodborne pathogen that causes illness inhumans and animals. In this study, 1,270 raw meat samples were collected from
markets in Seoul and were investigated for the distribution of Yersinia spp. In addition,
epidemiological analysis was performed assessing the biochemical, serological, genetic,
and virulence-associated characteristics of Y. enterocolitica. Yersinia spp. were detected
in 136(10.7%) samples, of which the most frequently isolated species was Yersinia
enterocolitica(57.4%), followed by Yersinia intermedia(33.8%), Yersinia frederiksenii
(6.6%), and Yersinia kristensenii (2.2%). Of the 78 Y. enterocolitica isolates, biotypes
1A(83.3%), 2(15.4%), and 3(1.3%), were identified; biotypes 1B, 4, and 5 were not
identified. Serotypes included O:1,2(3.9%), O:5(44.9%), O:8(10.3%), and NT (not
typeable)(41.0%); serotypes O:3 and O:9 were not isolated. The prevalence of virulence
genes included yadA(1.3%), inv(33.3%), ail(1.3%), ystA(1.3%), and virF(0%). This study
highlighted the importance of raw meat as a potential source of Y. enterocolitica
infection in Seoul.
