浙江省2001年钩端螺旋体病监测分析

Surveillance of Leptospirosis in Zhejiang Province in 2001

为了探讨钩体病流行规律 ,分析存在问题。用MAT法检测病人、水鸭和蛙血清抗体 ;同时分离培养病原体。用夹夜法捕鼠 ,采集鼠肾、猪肾、牛中段尿、蛙肾和水鸭肾分离培养病原体。结果表明 ,2 0 0 1年全省共发生钩体病 71例 ,死亡 1人 ,发病率为 0 15 7 10万 ,发病率比去年减少 8 4 6 %。病例主要分布在衢州、丽水和台州市 (地 )的江山、常山、三门、松阳、青田、莲都和龙游等县市。衢州、丽水、台州市的发病数占全省发病总数的92 96 %。病例主要分布在 7- 10月 ,占 92 96 % ,但是季节分布有分散趋势。职业以农民为主 ,占 95 77% (6 8 71)。年龄以 15 - 5 0岁为主 ,占 74 6 6 % (5 3 71)。男女之比为 2 5∶1(5 1 2 0 )。共检测病人血清 4 4份 ,阳性 13份 ,阳性率为 2 9 5 4 % ,菌群主要为黄疸出血群。全省鼠密度为 2 97%。鼠种构成以黑线姬鼠为优势种 ,占 5 2 14 %。解剖培养鼠肾 4 91对 ,阳性 12对 ,鼠带菌率为 2 4 4 %。菌株分别为秋季热群和流感伤寒群。解剖蛙肾 5 5 3对 ,阳性 13对 ,阳性率为 2 35 % ;检测牛中段尿 6 1份 ,阳性 1份 ;检测猪肾 84对 ,全部阴性。测定水鸭血清 2 0份 ,阳性5份 ,阳性率为 2 5 % ,菌株主要为秋季群 ;蛙血 2 9份 ,阳性 1份 ,阳性率为 3 4 5 % ,菌株为秋季群。以此?

Objective: The aim of this article was to analysis the prevalence of leptospirosis in Zhejiang province in 2001. Method: Using MAT to test the serum antibody in patients, ducks and frogs. Culturing and isolating the leptospira specimens with the serum of them. Results: In 2001, 71 cases were detected in the whole province. The average incidence in 0 157 per 100 000 , and one of them was died. Most of them were in Quzhou?Lishui and Taizhou city. The positive rate of the serum antibody in patients, frogs and ducks was 29 54%, 3 45% and 25%, respectively. The culture positive rate of patients blood mous's kidney frog's kidney was 0%, 2 44% and 2 35%, respectively. Conclusion: It can not be relaxed to prevent and control the prevalence of Leptospirosis. We showld be on guard against the outbreak after flood and enhance the surveillance of it.〔
