Abstract
In order to investigate human-louse phylogeny, we partially sequenced two nuclear (18S rRNA and EF-1α) and one mitochondrial (COI) genes from 155 Pediculus from different geographical origins. The phylogenetic analysis of 18S rRNA and EF-1α sequences showed that human lice were classified into lice from Sub-Saharan Africa and lice from other areas. In both clusters, head and body lice were clearly grouped into two separate clusters. Our results indicate that the earliest divergence within human pediculidae occurred between African lice and other lice, and the divergence between head and body lice was not the result from a single event.

Afin d'étudier la phylogénie des poux humains, nous avons partiellement séquencé deux gènes nucléaires (ARNr 18S et EF-1α) et un mitochondrial (COI) chez 155 Pediculus d'origines géographiques diverses. L'analyse phylogénique des séquences des gènes ARNr 18S et EF-1α a montré que les poux d'Afrique sub-saharienne étaient différents des poux d'autres origines. Dans ces deux groupes, les poux de tête et de corps étaient clairement séparés. Nos résultats montrent que la divergence initiale au sein des poux humains est survenue entre ceux d'Afrique et les autres, et que la divergence entre poux de tête et de corps n'a pas résulté d'un seul événement.
