Molecular phylogenetic analysis of the ftsZ gene sequence identified from M. alternatus, together with representatives of the Wolbachia supergroups A and B. A supergroup D sequence (Wuchereria bancrofti) was used as an outgroup. A total of 523 aligned nucleotide sites were subjected to the analysis. A maximum likelihood (ML) tree is shown, and a neighbour-joining (NJ) tree exhibited the same topology. Bootstrap probabilities (ML/NJ) no less than 50 per cent are shown at the nodes. Accession numbers are in brackets.
