Abstract

In the Kanto area a total of 245 wild rats were captured. All rats captured in Ikebukuro (110 rats) and 9 out of 41 rats in Yokohama were Rattus rattus, and all other 126 rats were Rattus norvegicus. In Kashima and Ikebukuro, listeria was isolated from 28 rats (77.8%) and 27 rats (24.5%), respectively, but in the other 4 areas listeria was isolated from 0-7% rats. Listeria monocytogenes was isolated from 12 rats (10.9%) captured in Ikebukuro and 2 rats in Kashima and Numazu. The frequent isolation of L. monocytogenes in buildings suggests the possibility of R. rattus as a reservoir of L. monocytogenes and the continual environmental contamination in buildings by L. monocytogenes.

摘要

在关东地区，共捕获了245只野生大鼠。在池袋捕获的所有大鼠（110只）以及横滨41只大鼠中的9只均为黑家鼠，其他126只大鼠均为褐家鼠。在鹿岛和池袋，分别从28只大鼠（77.8%）和27只大鼠（24.5%）中分离出李斯特菌，但在其他4个地区，从0 - 7%的大鼠中分离出了李斯特菌。从池袋捕获的12只大鼠（10.9%）以及鹿岛和沼津的2只大鼠中分离出了产单核细胞李斯特菌。在建筑物中频繁分离出产单核细胞李斯特菌表明，黑家鼠有可能是产单核细胞李斯特菌的宿主，并且建筑物环境持续受到产单核细胞李斯特菌的污染。
