摘要:

2014年2~3月在云南省宾川县州城镇2个行政村中的6个自然村,开展片形吸虫病流行病学调查,对当地5岁以上常住人口进行血清学检测,血清阳性者采用260目尼龙绢集卵沉渣镜检和Kato-Katz法检查24 h全粪中片形吸虫卵。结果显示,人群血清片形吸虫抗体总阳性率为3.0%(36/1 207),男、女性抗体阳性率分别为2.3%(12/530)和3.6%(24/677),两者差异无统计学意义(u=1.46,P>0.05)。州城和白庄行政村抗体阳性率分别为4.0%(24/616)和2.0%(12/591),两者差异有统计学意义(u=2.07,P<0.05)。血清阳性者粪检阳性率为6.5%(2/31),粪检阳性者1例为2012年巨片形吸虫病暴发时病例,发现的虫卵为变性虫卵;1例为新发病例,对新发病例进行临床诊疗观察,确定为片形吸虫病慢性期病例。

Abstract:

From February to March 2014, six natural villages in Zhoucheng Town, Binchuan County of Yunan Province, were randomly selected by cluster sampling. Serum anti-fascioliasis IgG was detected by ELISA. The sero-positive individuals were further tested for Fasciola infection using sediment detection with nylon bag(260 meshes) and Kato-Katz method. Among 1 207 sampled persons, the sero-positive rate was 3.0%(36/1 207). The rate in males and females was 2.3%(12/530) and 3.6%(24/677)(u=1.46, P>0.05). The sero-positive rate in Zhoucheng Village and Baizhuang Village was 4.0%(24/616) and 2.0%(12/591), respectively(u=2.07, P<0.05). The positive rate of stool examination in serum-positive persons was 6.5%(2/31). One stool-egg-positive patients was the case in 2012 outbreak, and the eggs were stale. The other patient was newly infected, and further clinical diagnosis indicated that it was a case of chronic fascioliasis.
