Abstract:

水体和土壤保存致病性钩端螺旋体(简称钩体)是钩体病地理流行病学观察研究的重要问题之一。1988~1992年笔者在滇西、滇南的5个县市进行了调查。采用过滤培养分离法,结果在雨季取样的孟连、华坪县得到的全是水生性钩体,干季取样的耿马、保山及盈江3个县市中的耿马县及保山市的水、土中共分离得致病性钩体8株,两地平均检出率为3.31%(8/242),其中水2.14%(3/140)、土4.9%(5/102)。分属6个血清群:黄疸出血、致热群各2株,犬、流感伤寒、赛罗及澳洲群各1株,与当地人和动物感染的菌群相一致,为阐述钩体病疫源地结构等提供了新资料。

English Abstract:

The conservation of pathogenic leptospirae in water and soil is one of the important problems of geography-epidemiological survey of leptospirosis. We have conducted this investigation by using of filtration-culture isolation method in five counties in the west and southwest of Yunnan during 1988~1992. The results showed that the isolates from samples of water and soil collected between July and September in Menglian and Huaping county were leptospirae biflexa while in the samples of water and soil collected between November and December in three counties, 8 strains of L.interrogans were isolated from the samples of Gengma and Baoshan county. The total positive rate was 3.31% (8/242). The positive rate of water and soil was 2.14% (3/140) and 4.9% (5/102) respectively. Strains obtained in this investigation belong to six serogroups:Icterohaemorrhagiae and Pyrogenes in 2 respectively, Canicola, Grippotyphosa, Sejroe and Australis in 1 respectively. These serogroups of leptospirae obtained from water and soil were corresponded with the serogroups obtained from the patients and animals with leptospirosis in local area. This survey provided new data for expounding the structure of the focus of leptospirosis.
