FIG. 1.

Phylogenetic dendrogram inferred using parsimony approach from alignment of 301-bp sequences for the representatives of the 10 novel partial msp4 sequence types encountered in this study (ii to xi) and representatives of nine partial msp4 sequence types described previously (6). Numbers on the branches indicate the percent support for each of the branching orders proposed, as determined by bootstrap analysis of 1,000 replicates.
