目的：为了解不同类型地理景观中钩端螺旋体病血清群（型）的分布。方法：60年代～90年代初．我们对安徽省淮北平原、江淮丘陵和皖南山区三种不同类型自然地理区划内的850O份自然人群、3596份钩体病人及10种动物的3699W血清标本．以MAT法进行了血清学检测。结果：平均阳性率分别为15．8％、34．8％和23.7％。感染的血清群（型）分别为14和13个血清群（型）。结论：研究结果表明，自然人群、钩体病人和动物三者之间感染的血清群（型）基本一致；淮北平原、江淮丘陵流行区感染的主要血清群（型）是波摩那群（型），猪、牛是主要的带菌动物和传染源；皖南山区流行区感染的则主要是黄疸出血群（型），鼠、牛是主要的带菌动物和传染源。为我省对钩体病采取针对性的预防措施提供了依据。
Purpose: To understand the distribution of leptospirosis serogroups in different types of landscapes. Methods: 60’s ~ early 90’s. We collected 3699W serum samples of 850O natural populations, 3596 leptospira patients, and 10 species of animals in three different types of natural geographical divisions in Huaibei Plain, Jianghuai Hilly and Wannan Mountain in Anhui Province. Serological tests were performed by the MAT method. Results: The average positive rates were 15.8%, 34.8% and 23.7% respectively. Infected serogroups were 14 and 13 serogroups (type), respectively. CONCLUSION: The results showed that the serogroups (serotypes) of infection in natural population, leptospirosis patients and animals were basically the same. The main serogroups of infection in epidemic areas of Huaibei Plain and Jianghuai Hilly area were Pomona (type) , Pigs and cattle are the main carriers of infectious bacteria and source of infection. In southern Anhui mountainous area, the infection is mainly of hemorrhagic jaundice (type). Rats and cattle are the main carriers of infectious animals and sources of infection. For our province to leptospirosis to take targeted preventive measures provide the basis.
