Norway rats (Rattus norvegicus) are hosts for various microbes. Homeless people who have contact with rats may be at risk of infection by them. The Los Angeles County Department of Health Services initiated a seroepidemiologic study among patients who used a free clinic in downtown Los Angeles; 200 serum specimens obtained for other routine assays were tested for antibodies to ratborne pathogens and other agents. The seroprevalence of antibody to hepatitis E virus in this population was 13.6%; to Bartonella elizabethae, 12.5%; to B. quintana, 9.5%; to B. henselae, 3.5%; to Seoul virus, 0.5%; and to Rickettsia typhi, 0.0%. This study found that patients and locally trapped rats had antibodies to some of the same agents.
褐家鼠（挪威鼠）是多种微生物的宿主。与老鼠接触的无家可归者可能有被它们感染的风险。洛杉矶县卫生服务部在使用洛杉矶市中心一家免费诊所的患者中开展了一项血清流行病学研究；对为其他常规检测采集的200份血清标本进行了鼠传病原体及其他病原体抗体检测。该人群中戊型肝炎病毒抗体的血清阳性率为13.6%；伊丽莎白巴尔通体抗体为12.5%；五日热巴尔通体抗体为9.5%；汉赛巴尔通体抗体为3.5%；汉城病毒抗体为0.5%；伤寒立克次体抗体为0.0%。该研究发现，患者和当地捕获的老鼠对某些相同病原体具有抗体。
