The prevalences of antibodies against Bartonella henselae and Ehrlichia canis were determined in sera from 228 dogs in 5 communal lands of Zimbabwe, areas where traditional subsistence agro-pastoralism is practised. The sera were collected from apparently healthy dogs during routine rabies vaccination programmes and tested with indirect fluorescent antibody assays using B. henselae (Houston-I) and E. canis (Oklahoma) as antigens. We found reactive antibodies (> or =1:80) against B. henselae in 14% of the dogs tested. Seropositive animals were found in Bikita (41%; 17/42), Omay (13%; 6/48), Chinamora (5%; 2/38) and Matusadona (15%; 7/48). No seropositive dogs were found in Chiredzi (0%; 0/52). Antibodies reactive with E. canis (> or =1:80) were found in 34% of the dogs tested, from Bikita (88%; 37/42), Chiredzi (31%; 16/52), Omay (17%; 8/48), Chinamora (26%; 10/38) and Matusadona (15%; 7/48). Our survey shows dogs in the communal lands of Zimbabwe are frequently exposed to E. canis and B. henselae or closely related species. Further studies are indicated to determine the pathogenicity of the organisms infecting these dogs and their clinical significance.
在津巴布韦5个社区土地（实行传统自给农牧业的地区）的228只狗的血清中，测定了抗汉赛巴尔通体和犬埃立克体抗体的流行率。这些血清是在常规狂犬病疫苗接种计划期间从看似健康的狗身上采集的，并使用汉赛巴尔通体（休斯顿-I）和犬埃立克体（俄克拉荷马）作为抗原，通过间接荧光抗体试验进行检测。我们发现，在检测的狗中，14%的狗有抗汉赛巴尔通体的反应性抗体（≥1:80）。在比基塔（41%；17/42）、奥迈（13%；6/48）、奇纳莫拉（5%；2/38）和马图萨多纳（15%；7/48）发现了血清阳性动物。在奇雷兹没有发现血清阳性的狗（0%；0/52）。在检测的狗中，34%的狗有与犬埃立克体反应的抗体（≥1:80），这些狗来自比基塔（88%；37/42）、奇雷兹（31%；16/52）、奥迈（17%；8/48）、奇纳莫拉（26%；10/38）和马图萨多纳（15%；7/48）。我们的调查表明，津巴布韦社区土地上的狗经常接触犬埃立克体和汉赛巴尔通体或密切相关的物种。需要进一步研究以确定感染这些狗的病原体的致病性及其临床意义。
