| 中文摘要: |
| 1986年前,我国恙虫病仅知流行于浙江以南地区,主要属夏季型,以地里纤恙螨为主要媒介。我所于1986年10月在南京发现有恙虫病的存在,1986~1992年通过调查研究证明:南京和苏北的东台、海安、如东等7县市有恙虫病的流行;属秋冬型;以黑线姬鼠、社鼠、褐家鼠和大麝鼩为主要储存宿主;以小盾纤恙螨为传播媒介;秋冬型恙虫病立克次体属弱毒株较难分离,接种标本的小白鼠经用环磷酰胺等处理后,已从鼠、恙螨和病人分离到14株;血清分型属Gilliam型;疫源地类型可分为平原型和丘陵型两型。 |

| Before 1988, tsutsugamushi disease was known only prevalent in south to Zhejiang Province in our country, belonged to the summer type and Leptotrombidium (L.) deliense was regarded as the main vector. In October 1986, the authors found this disease in Nanjing and carried out a series of studies in 1986~1992. The results were as follows:Tsutsugamushi disease was epidemic in Nanjing and north of Jiangsu (including:Dongtai, Haian, Rudong, Jinhu, Hanjiang, Jiangdu); belonged to the autumn-winter type; the main reservoir hosts were Apodemus agrarius, Rattus confucianus, R.norvegicus and Crocidura lasiura; the transmitting vector was L. (L.) scutellare; the pathogen of tsutsugamushi disease of the autumn-winter typeRickettsia tsutsugamushi belonged to low-virulent strain, and could not easily be detected; after the inoculated mice were treated with diluted cyclophosphamide solution, 14 strains of R.tsutsugamushi have been isolated from rats, mites and patients; serological typing of their sera showed that they belonged to the Gilliam type; natural foci in Jiangsu could be divided into two types-flat land and hilly land. |
