摘要
一、本文用地理流行病学、描述流行病学，血清流行病学等多种方法对湖南省３６年钩体病进行了综合分析，阐明了我省钩体病疫区分布、流行强度、流行形式，查明了主要宿主及菌群（型）分布，人群带菌菌群以及血清抗体水平，对今后防治工作有意义。二、发病率以Ⅳ区湘东丘陵区１６．７８／１０万最高，其次是Ⅵ区洞庭平原区次之１４．８６／１０万，Ⅴ区湘中丘陵区４．６２／１０万最低。三、我省钩体病自１９５８～１９９３年以来，平均发病率为９．０１／１０万，平均病死率为３．１１％，１９７３、１９８７、１９９３年曾出现过三次大流行，发病率分别为４６．８／１０万、２２．４８／１０万、２０．６８／１０万。流行主要形式是稻田型。四、病人菌群１３群，血清抗体为１４群。按地理区划病人菌群分布以Ⅴ区、Ⅳ区最复杂，有１２群；Ⅰ区为３群，较简单；血清抗体Ⅳ区为１４群，Ⅰ区为６群。病人分离菌群与血清抗体群在相同的地理区划显示相符。五、７种家畜、家禽所带菌群可分为９群。猪带菌９群，最复杂；犬带菌３群、驴带２群、牛的标本仅分出一株未定群。从血清抗体来看，猪血清抗体最为复杂；牛次之、犬感染９群。猪主要为圈养，活动范围局限，在我省不是主要传染源；犬带犬群，曾引起个别地?
This article analysed the incidence of leptospirosis in Hunan province in last 36 years by using geographical epidemiology, describtive epidemiololgy and seroepidemiology. The focus distribution, power of epidemic, type of epidemic were described.The main host and flora (bacterial type)distribution, flora of carrier, and serum antibody level were explored. These consults have significance to leptospirosis control.2.The highest incidence is in hilly area of eastern part(region Ⅳ) of Hunan province, the middle incidence is in Dongting plain area(region Ⅵ), the lowest incidence is in hilly area of middle part(region Ⅴ)of Hunan province. The incidences are 16.78/100000, 14.86/100000 and 4.62/100000 respectively in these 3 regions.3. From 1958 to 1993, the average incidence of leptospirosis is 9.01/100000 in Hunan province.The average death rate is 3. 11%. 3 heavy epidemics occurred in 1973, 1987 and 1993. The incidence of leptospircois during these three epidemics are 46.8/100000, 22.48/100000 and 20.68/100000 respectively. The main type was rice- field.4.13 flora and 14 serum antibody flora have been discovered. According to the geographical region,the most complicated flora were in region Ⅴand Ⅳ, among these have 12 complicated flora; region 1 only 3.There were 14 serum antibody flora were in regionⅣ, and 6 in region 1. The flora and serum antibody flora were the same in within each particular regions.5.9 flora have been isolated from 7 kinds of livestock and poultry. 9 flora were found in Surdae carry, 3 in canidae, 2 in Donkey, a uncertain flora were found in Bovidae. According to the serum antibody,Surdae' s were the most complicated, Bovidae's were in the middle, and Canidae's were the simplest. Surdae were raised in home, area for maneuvering is not so wide, Surdaea is not the main soure. Canidae carries Canine flora, a few local epidemics were caused by Canidae. Bovidae were raised in outside. Further study is needed for the significance of Bovidae as the cause of epidemic.6.Leptospirosis was cau
