Figure 3. Analysis of spacer PM1, S2, S5 and concatenation of the four spacers.

Phylogenetic analysis of African (black) and Non African lice (blue) using Maximum likelihood method based on spacer PM1 (A), spacer S2 (B), spacer S5 (C), the concatenation of the four spacers (D). For lice being heterozygote, the two alleles were included in the trees and they were called the same with one letter “a” or “b” to distinct them.
