摘要: Listeria monocytogenes causes foodborne illnesses through consumption of ready-to-eat foods. Although 135-201annual listeriosis cases have been estimated in Japan, the details regarding clinical isolates such as infection source, virulence level, and other genetic characteristics, are not known. In order to uncover trends Japan use knowledge for prevention measures be taken, characteristics past human needs elucidated. For this purpose, multilocus tandem-repeat sequence analysis (MLTSA) multi-virulence-locus typing (MVLST) were used study. The showed a variety genetically distant genotypes, indicating they from sporadic cases. However, MVLST profiles 7 identical those epidemic clone (EC) I isolates, which caused several serious outbreaks countries, suggesting possibility that strong potential originated single outbreak. Moreover, 6 Japanese food shared their genotypes with ECI there may risks outbreak Japan. This is first investigational study on isolates. happened presumably sporadic, but it still possible some outbreaks, future also exist.
