Abstract

No focalization of rats (Rattus tiomanicus and R. argentiventer) infected with Rickettsia tsutsugamushi could be discerned over a 500 m trapping transect at the border between a forest and lalang grass (Imperata cylindrica). R. tiomanicus appeared to occupy 250 m of the transect on the average and had periods during which infections were observed which averaged 97 days. Calulations indicated that more than 50% of individuals become infected over their life-time. The high rate of infection in this and other areas described in earlier publications and the habits of the rats suggest that infected mites are densely and widely dispersed in the areas studied in Malaysia.

摘要

在森林与白茅（Imperata cylindrica）交界处500米的诱捕样带上，未发现感染恙虫病立克次体的蒂曼大鼠（Rattus tiomanicus）和银腹大鼠（R. argentiventer）有聚集现象。蒂曼大鼠平均占据样带250米，且有感染期，感染期平均为97天。计算表明，超过50%的个体在其一生中会被感染。本研究及早期出版物中描述的其他地区的高感染率以及大鼠的习性表明，在马来西亚研究的区域内，感染的螨类分布密集且广泛。
