1993年10月在我国南部沿海恙虫病高发区和东部沿海恙虫病低发区进行了恙虫病媒介宿主动物的比较流行病学研究。两个地区的鼠类区系和种群密度无明显差异。东部沿海黑线姬鼠血清抗体阳性率较高（南部沿海为43.2%，东部沿海为63.6%）。抗体阳性率与血清学指标呈高度相关（r = 0.87）。血清和媒介螨（小盾纤恙螨（Leptotrobidium scutellare）和小盾纤恙螨（L.苍白球）。L.南部沿海以小盾恙螨为优势种，其恙螨指数为110.6，占总恙螨数的74.9%;东海岸地区以苍白球为主，恙螨指数为126.3，占总恙螨数的60.4%。随着L.在恙虫病发病率最高的南部沿海地区发现了小盾壳菌，认为小盾壳菌是恙虫病的病原。小盾壳菌是重要的媒介生物。苍白球，这可能是由于更频繁的病媒-人接触。
Comparative epidemiological studies on vector reservoir animals of tsutsugamushi disease were carried out in between south coast (the highest endemic) areas and east coast (low endemic) areas in October 1993. Fauna of field rodents and their population densities were not different between two areas. Antibody positive rate of Apodemus agrarius sera was higher in east coast (43.2% in south coast and 63.6% in east coast). High correlation (r = 0.87) was shown between antibody positive rate of A. agrarius sera and population density of the vector mites (Leptotrombidium scutellare and L. pallidum). L. scutellare was predominant in south coast, showing 110.6 chigger Index (74.9% of the total chiggers), whereas L. pallidum was predominant in east coast, showing 126.3 chigger index (60.4% of the total). As higher population density of L. scutellare was found in south coast where the prevalence rate of tsutsugamushi disease is the highest, it is believed that L. scutellare is more important vector species than L. pallidum, which may result from more frequent vector-human contact.
