Results of the Multi-Spacer-Typing of African lice.

Phylogenetic analysis of African (black) and Non African lice (blue) (A) The first 69 bp of the alignment of a subset of PM2 spacer sequences. Two polymorphisms (shown with arrows) discriminate between African and Non-African lice (B) Phylogenetic tree based on PM2 sequences using Maximum likelihood method. For lice being heterozygote in PM2 spacer, the two alleles were included in the tree and they were called the same with one letter “a” or “b” to distinct them.

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.
Figure 4.
Proportion of each genotype among African (black) and Non-African (blue) lice.
The name (ID numbers) of the genotypes found in both African and Non African countries were framed. Genotypes (either African and Non African) found in only one louse were not represented and were grouped as “others”.
Figure 5.
Geographic repartition of the four spacers genotypes.
Genotypes found in at least two countries are colored (one color per genotype) and genotypes found in only one country are in white. The size of the symbols vary with the number of lice found for each genotype. Only genotypes found in at least two lice were represented.
