日本港湾地区啮齿动物携带肾综合症出血热病毒的调查分析

A surveyed on Hantavirus Infection among rodents at the harbours in Japan

本文作者对日本的口岸地区(东京港、羽田机场、清水港、小樽港、名古屋港、名古屋市区和葛西海滨公园)的啮齿动物携带肾综合症出血热病毒抗体情况进行了调查。结果以名古屋港阳性率最高,为23.68%,其次为东京港,阳性率为12.77%,而在东京的葛西海滨公园和羽田机场则没有检测到抗体。本文还用VeroE-6细胞,从名古屋港的一只褐家鼠的肺组织分离到一株病毒。提示日本港湾地区的啮齿动物携带有肾综合症出血热病毒。

Seroepizoot iological study of hantavirus infection among 469 urban rats captured in Kasai Seaside Park, Tokyo Port, Haneda Airport, Shimizu Port, Otaru Port,Nagoya City and Nagoya Port was carried out during the period from 1990 to 1994 using the indirect fluorescent antibody test and western blot (WB) , 29 out of 469 rat sera were antibody(IFA) positive by IFA and WB, i.e., Nagoya Port (23.68%, 18/76), Tokyo Port (12.77%, 6/47), Shimizu Port (5.71%, 2/35), Nagoya City(1.2%, 2/167 ) and Otaru Port (1.5%, 1/65 ) .Two other regions were sero-negative.A Hantavirus strain was isolated from a rat captured in Nagoya Port. The persistence of Hantavirus among rats in Tokyo Port, Shimizu Port, Nagoya City and the existence of Hantavirus in Otaru Port were demonstrated.
