Maximum-likelihood phylogenetic tree of Angiostrongylus cantonensis, A. malaysiensis, A. vasorum, A. chabaudi, A. costaricensis and A. dujardini based on the partial ITS2 sequences.
Support values (ML bootstrap/MP bootstrap/NJ bootstrap/Bayesian posterior probabilities) are shown above the branches. A dash (-) instead of a numerical support value indicates that a particular grouping was not found by that method of analysis. Bold letters indicate sequences obtained in the present study. Numbers in parentheses following each newly obtained sequence indicate the number of larvae possessing that sequence.
