A total of 1,835 Yersinia spp. were isolated from 925 (60.5%) of 1,530 wild mice and from 139 (79.9%) of 174 moles living in mountainous areas of eastern Shimane Prefecture, Japan. The Yersinia spp. included 1,106 Yersinia enterocolitica, 26 Y. enterocolitica-like, 176 Yersinia mollaretii, 149 Yersinia frederiksenii, 70 Yersinia intermedia, 231 Yersinia kristensenii, 5 Yersinia aldovae, and 72 Yersinia pseudotuberculosis. Human pathogenic Y. enterocolitica was not isolated. Y. pseudotuberculosis was divided into 10 virulent 40- to 50-MDa plasmid-positive (P+) strains (serotypes 1b, 4b, and untypeable) and 62 plasmid-negative (P-) strains (serotypes 1b, 2b, 2c, 4a, 5a, 5b, 6, 7, and untypeable). P+ strains of serotypes 1b (two strains), 4b (seven strains), and untypeable (one strain) were isolated from nine Apodemus specious and one Apodemus argenteus. The isolates of Yersinia spp. were more frequently detected in newborn mice and during the breeding season. The P+ Y. pseudotuberculosis strains were recovered at less than 10(4) cells per g of the cecal contents. Thus, the prevalence of Yersinia spp. in small wild animals depends on the newborn animals born during the cold months, and wild mice in mountainous areas are important reservoirs of Y. pseudotuberculosis.
从日本岛根县东部山区的1530只野生小鼠中的925只（60.5%）以及174只鼹鼠中的139只（79.9%）共分离出1835株耶尔森菌属细菌。这些耶尔森菌属细菌包括1106株小肠结肠炎耶尔森菌、26株类小肠结肠炎耶尔森菌、176株莫拉雷耶尔森菌、149株费氏耶尔森菌、70株中间耶尔森菌、231株克氏耶尔森菌、5株奥尔登耶尔森菌和72株假结核耶尔森菌。未分离出具有人类致病性的小肠结肠炎耶尔森菌。假结核耶尔森菌分为10株毒力强的40至50兆道尔顿质粒阳性（P+）菌株（血清型1b、4b和无法分型）和62株质粒阴性（P-）菌株（血清型1b、2b、2c、4a、5a、5b、6、7和无法分型）。血清型1b（2株）、4b（7株）和无法分型（1株）的P+菌株从9只大林姬鼠和1只银黑姬鼠中分离得到。耶尔森菌属细菌在新生小鼠和繁殖季节更频繁地被检测到。每克盲肠内容物中回收的P+假结核耶尔森菌菌株少于10^4个细胞。因此，野生小动物中耶尔森菌属细菌的流行取决于寒冷月份出生的新生动物，山区的野生小鼠是假结核耶尔森菌的重要储存宿主。
