目的 :分析比较河南省不同流域稻田型钩端螺旋体病流行特征的异同 ,为制订相应的预防措施提供依据。方法 :主要采用现况研究、病原分离、血清学检验等方法。结果 :淮河流域及黄河流域稻田型钩体病存在 :( 1)流行形式的差异 :淮河流域流行形式较单一 ,为稻田型 ;而黄河流域则较复杂 ,有稻田型、雨水 -稻田型、洪水 -稻田型。 ( 2 )疫区环境的不同 :淮河流域疫区主要在丘陵地带 ,较为固定 ;黄河流域疫区主要在平原 ,流行地区逐年扩大。 ( 3)流行菌群皆以黄疸出血群为主 ,宿主动物为鼠类 ,主要是黑线姬鼠。 ( 4)淮河流域存在钩体病的经济疫源地 ,现又证明存在自然疫源地 ;而黄河北岸的疫区为单纯自然疫源地。结论 :由于地理环境、气候条件等不同 ,两地的稻田型钩体病既有许多共同点 ,也有不同之处 ,故应采取相应的防治措施。
OBJECTIVE: To analyze and compare the similarities and differences between the epidemiological characteristics of paddy-type leptospirosis in different valleys in Henan Province, and to provide the basis for formulating the corresponding preventive measures. Methods: The current status of research, pathogen isolation, serological tests and other methods. Results: The prevalence of paddy field leptospirosis in the Huaihe River and Yellow River: (1) Differences in epidemic forms: The prevailing forms in the Huaihe River Basin are more single and in the form of paddy fields; while the Yellow River Basin is more complex with paddy field type, rain-paddy type, flood - paddy type. (2) Different epidemic areas: The epidemic areas of the Huaihe River Basin are mainly in the hilly areas, which are relatively fixed; the epidemic areas of the Yellow River Basin are mainly expanded in the plains and endemic areas year by year. (3) The prevalence of jaundice groups are dominated by bleeding, host animals for the rodents, mainly Apodemus. (4) The economic foci where leptospirosis is present in the Huaihe River Basin now prove that there is a natural foci, while the epidemic area on the north bank of the Yellow River is a mere natural foci. Conclusion: Due to geographical environment and climatic conditions, there are many commonalities and differences in paddy field leptospirosis between the two places. Therefore, appropriate control measures should be taken.
