本文作者用组织学方法比较了巴西勾虫、锡兰勾虫和犬勾虫幼虫在其正常宿主(犬)皮肤内的移行习性。9只6周龄的幼犬按感染持续时间的不同(半小时、2小时和6小时)分为3组,每犬分别经肤感染1种幼虫2,000条,感染后作皮肤连续切片。结果:3种勾虫的移行习性有许多类似之处,尤以锡兰勾虫和犬勾虫更为相近。但巴西勾虫和锡兰勾虫、犬勾虫在习性和移行速度之间却有明显的差异。巴西勾虫幼虫比其他2种勾虫幼虫能更
The authors compared the migratory behavior of the Gracilaria sylvaticus, Trichoplusia sylvaticus, and the tick larvae in their normal host (canine) skin using histological methods. Nine 6-week-old puppies were divided into 3 groups according to the duration of infection (half an hour, 2 hours and 6 hours). Each dog was infected with 1 larvae of skin by skin. Results: There are many similarities in the migration habits of the three species of hookworm, especially the similarities between the striped hookworm and the striped hookworm. However, there is a clear difference between the habitat and the migrating speed of the dogs and cats in Brazil. Brazilian tap larvae larvae more than the other two species
