Fig 4. Maximum-likelihood phylogenetic tree of Angiostrongylus cantonensis, A. malaysiensis, A. vasorum, A. costaricensis, Aelurostrogylus abstrusus and Metastrongylus salmi (the last two as outgroups) based on partial COI 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. AC1-AC13 are the 13 distinct haplotypes of A. cantonensis; AM1-AM4 are the 4 distinct haplotypes of A. malaysiensis. Numbers in parentheses following each newly obtained sequence indicate the number of larvae possessing that sequence.
