The head and body lice of humans are genetically distinct (Insecta: Phthiraptera, Pediculidae): evidence from double infestations (2005)

Leo, NP, Hughes, Jane, Yang, X, Poudel, SKS, Brogden, WG, Barker, SC

Little is known about the population genetics of the louse infestations of humans. We used microsatellite DNA to study 11 double infestations, that is, hosts infested with head lice and body lice...
