Molecular differentiation and phylogenetic relationships of three Angiostrongylus species and Angiostrongylus cantonensis geographical isolates based on a 66-kDa protein gene of A. cantonensis (Nematoda: Angiostrongylidae)

The phylogenetic relationships and molecular differentiation of three species of angiostrongylid nematodes (Angiostrongylus cantonensis, Angiostrongylus costaricensis and Angiostrongylus malaysiensis) were studied using the AC primers for a 66-kDa protein gene of A. cantonensis. The AC primers succe...

A. costaricensis is the most distant taxon. A. cantonensis is a sister group to A. malaysiensis; these two taxa (species) are clearly separated.
