目的了解2009年卢氏县正常人及主要家畜(羊、牛、犬)立克次体血清流行病学特点。方法根据地理位置及农村牲畜饲养分布特点,选择官道口、范里、文峪、东明4个乡镇为调查点。以间接免疫荧光法检测人和家畜斑疹伤寒群立克次体、斑点热群立克次体、恙虫病东方体、贝氏苛克斯氏体、查菲埃立克体、人粒细胞无形体、巴尔通体、海南斑点热分离株等8种常见立克次体血清抗体。结果在4个调查点244份人血清和97份家畜血清中8种立克次体抗体均有检出。人群血清学检测阳性率最高为人粒细胞无形体(26.23%),最低为恙虫病东方体(0.82%);畜群感染率最高为海南斑点热分离株(90.72%),最低为贝氏苛克斯氏体(8.25%)。人群人粒细胞无形体感染率有明显地区间差异;羊的斑疹伤寒群立克次体和恙虫病东方体感染率,牛的巴尔通体感染率,犬的斑点热群立克次体感染率明显高于其它畜种。结论卢氏县人畜间广泛存在多种立克次体感染,局部地区高发、多发,应作进一步调查研究并加强防控。
Objective To understand the epidemiological characteristics of Rickettsia in normal and major livestock (sheep, cattle and canine) in Lushi County in 2009. Methods According to the geographical location and the distribution characteristics of livestock in rural areas, four townships, Guandaokou, Fanli, Wenyu and Dongming, were selected as the investigation points. Indirect immunofluorescence assay was used to detect human and domestic typhus Rickettsia, Spotted fever group Rickettsia, Tsutsugamushi disease Oriental body, Bayesian Hokkassia, Chaffy Ehrlichia, human granulocyte invisible Body, Bartonella, Hainan hot spot spotted eight common rickettsial serum antibodies. RESULTS: Totally 244 Rickettsia antibodies were detected in 244 human serum samples and 97 serum samples from 4 investigation sites. The seropositive rate of human serology was the highest (26.23%) and the lowest was 0.92% (0.82%). The herd infection rate was the highest (90.72%) in Hainan and the lowest was Baxter Schist (8.25%). There was a significant difference in the rate of infection of human myeloid leprosy among the populations. The infection rates of rickettsia and scrub typhus, the prevalence of Bartonella in cattle, the infection rate of rickettsia Obviously higher than other species. Conclusion There are many rickettsial infections among humans and animals in Lushi County. In some areas, high incidence and multiple occurrences of rickettsia are needed. Further investigations and studies should be conducted to prevent them.
