2007-2009年浙江省磐安县钩端螺旋体病宿主动物监测分析

Surveillance of host animals of leptospirosis in Pan’an county, Zhejiang province,2007 - 2009

摘要: 目的了解浙江省磐安县野鼠、牛、猪、鸭和青蛙钩端螺旋体带菌情况。方法对野鼠鼠肾、牛中段尿、猪肾、鸭肾和青蛙肾等进行钩端螺旋体菌株的分离培养。结果 2007 - 2009年磐安县共分离培养到钩端螺旋体菌8株,经鉴定均为黄疸出血群。野鼠分离培养到7株,带菌率为2.13%;青蛙分离到1株,带菌率为0.33%;牛中段尿、猪肾和鸭肾未分离出钩端螺旋体菌。不同鼠种的带菌率社鼠8.33%、黄胸鼠3.03%。结论野鼠为磐安县钩端螺旋体病的主要传染源,黄疸出血群为主要的感染菌群。

Abstract: Objective To investigate the carriage of Leptospira of host animals and provide scientific evidence for the prevention and control of leptospirosis. Methods The kidney samples of rats, pigs, ducks, frogs and midstream urine of cattle were taken to isolate the pathogen. Results From 2007 to 2009, eight strains of Leptospira were isolated; all were L. icterohaemorrhagiae. Seven strains were detected in the rats with the positive rate of 2.13%; and 1 strain was detected in the frog with the positive rate of 0.33%. No Leptospira strain was detected in the remaining samples. The carriage rate was 8.33% for Rattus confucianus and 3.03% for Rattus flavipectus. Conclusion The field mouse was the predominant host animal of leptospirosis in Panan county, and L. icterohemorrhagiae was the major pathogen.
