幼虫

Analis presented in our 85 survey locations that were distributed in all counties on the Taiwan excluded the Taitung county, Hualien county, green island and orchid island. The altitude of P. analis habitats ranged from plain to the 400 m. The eleven types of habitats included bamboo plantation, windbreaks, orchard, dry riverbed, grassland, tea plantation, broadleaf forest, vegetable, paddy field, sugarcane field, and Arecae catechu showed the high diversity. The grassland was found in the highest ratio among 34 habitats and followed by the dry riverbed, which was found eleven sites.

经调查此虫在台湾分布情形，结果发现有栖地85处，台东县、花莲县、兰屿、绿岛除外，其余各县市皆有分布，从平原至海拔400公尺间；幼虫栖地类型有竹林、防风林、果园、河床、草地、茶园、阔叶树林、菜园、农田、蔗田及槟榔园等11型，显示其多样性高，其中草地型34处出现的频率最高，河床型13处次之。

Result: One of 29 (3.45%) blood clots and one of 112 (0.98%) spleen tissue from field rats were positive for 88bp DNA fragment. Eight DNA extracts from 39 (20.5%) chigger mites produced the predicted DNA fragment.

结果：从送检的29份鼠血块和112份脾组织中均检出阳性1份；从39份恙螨幼虫体内检出阳性8份。

Objective: To detect Orientia tsutsugamushi in Chigger Mites and the specimens collected from the rodents to analyse the epidemic trend of scrub typhus. To evalute the sensitivity and specificity of nested polymerase chain reaction and promote the research in molecular epidemiology of O.tsutsugamushi in the country.
