通过解剖镜检测分析了长白山林区不同地点、年龄组、性别及生活期中国林蛙肺线虫的感染情况.结果表明:中国林蛙肺线虫为双角棒线虫(Rhabdia bufonis),感染率为81.5%.不同地点肺线虫感染率差异不显著(P﹥0.05),不同地点肺线虫平均感染强度差异显著(P<0.05);不同年龄林蛙的肺线虫感染率差异较大,成体感染率及感染强度均大于幼体;不同性别的肺线虫感染差异不显著.长白山林区中国林蛙肺线虫感染率及感染强度较高,虫源分布广,认为是林蛙自然死亡的原因之一.
The infection status of Pulmonary Nematode Rana chensinensis from different locations, age groups, sex and life stage in Changbai Mountain was analyzed by means of dissecting microscope.The results showed that the infection rate of Rhabdis bufonis was 81.5 %. The infection rates of pulmonary nematodes in different locations were not significantly different (P> 0.05), and the average infection intensity of pulmonary nematodes was significantly different in different locations (P <0.05). The infection rates of lung nematodes were significantly different among different ages, The results showed that there was no significant difference in the infection rates of nematodes among different sexs.The prevalence and infection intensity of nematode nematodes in Changbai Mountain forest area was higher than that of larvae,
