恙螨粉尘螨是中国6种斑疹伤寒的主要媒介之一。在本研究之前，在湖南省部分地区发现了唾液酸菌，地理分布较窄。2016-2017年野外调查期间，我们在云南南部靖哈地区发现了唾液酸链球菌，中国。在15种小型哺乳动物寄主中，从6种寄主采集到乳链球菌。褐家鼠是L唾液酸中毒的优势宿主，捕获率为98.3%。与其他5种寄主相比，恙螨粉螨的感染率较高(P-M=11.7%)，平均丰度较高(MA=0.5)。这些结果揭示了乳杆菌对大鼠褐纹伊蚊具有一定的寄主特异性。粉尘螨在寄主上呈聚集分布(P
The chigger mite Leptotrombidium sialkotense is one of the 6 main vectors of scrub typhus in China. Before present study, L. sialkotense was found in some parts of Hunan province, China with a narrow geographical distribution. During field investigation 2016-2017, we found L. sialkotense in Jingha, southern Yunnan, China. Of 15 small mammal host species, L. sialkotense were collected from 6 species of the hosts. Rattus brunneusculus was a dominant host of L sialkotense, from which 98.3% of the mites were collected. The chigger mite showed a relatively high infestation prevalence (P-M= 11.7%) and mean abundance (MA=0.5) in comparison with the rest 5 host species. These results reveal a certain host specificity of L. sialkotense to a rat R. brunneusculus. The mite L. sialkotense showed an aggregated distribution on the host (P
