diphyllobothrium

1.The negative assosiation between Ligula intestinalis and Diphyllobothrium sp. and between Ligula intestinalis and Contracaecum rudolphii are obvious.

这与宿主行为和食性改变有密切关系。舌状绦与另两种有显著负协调关系。

2.The human infections of Diphyllobothrium latum，Toxocara canis，and Triodontophorus minor discovered by Lin(1924) from Beijing were the first records in the country.

林几(1924)在北京发现阔节裂绦，犬弓蛔，微小三齿线等肠道寄生感染者，均为我国首次报道。
