genome sequence of candidatus riesia pediculischaeffi, endosymbiont of chimpanzee lice, and genomic comparison of recently acquired endosymbionts from human and chimpanzee lice.the obligate-heritable endosymbionts of insects possess some of the smallest known bacterial genomes. this is likely due to loss of genomic material during symbiosis. the mode and rate of this erosion may change over evolutionary time: faster in newly formed associations and slower in long-established ones. the endosymbionts of human and anthropoid primate lice present a unique opportunity to study genome erosion in newly established (or young) symbionts. this is because we have a detailed phylo ...201425213693
molecular evolution of pediculus humanus and the origin of clothing.the human head louse (pediculus humanus capitis) and body louse (p. humanus corporis or p. h. humanus) are strict, obligate human ectoparasites that differ mainly in their habitat on the host : the head louse lives and feeds exclusively on the scalp, whereas the body louse feeds on the body but lives in clothing. this ecological differentiation probably arose when humans adopted frequent use of clothing, an important event in human evolution for which there is no direct archaeological evidence. ...200312932325
evolutionary relationships of "candidatus riesia spp.," endosymbiotic enterobacteriaceae living within hematophagous primate lice.the primary endosymbiotic bacteria from three species of parasitic primate lice were characterized molecularly. we have confirmed the characterization of the primary endosymbiont (p-endosymbiont) of the human head/body louse pediculus humanus and provide new characterizations of the p-endosymbionts from pediculus schaeffi from chimpanzees and pthirus pubis, the pubic louse of humans. the endosymbionts show an average percent sequence divergence of 11 to 15% from the most closely related known ba ...200717220259
the mitochondrial genome of the chimpanzee louse, pediculus schaeffi: insights into the process of mitochondrial genome fragmentation in the blood-sucking lice of great apes.blood-sucking lice in the genera pediculus and pthirus are obligate ectoparasites of great apes. unlike most bilateral animals, which have 37 mitochondrial (mt) genes on a single circular chromosome, the sucking lice of humans have extensively fragmented mt genomes. the head louse, pediculus capitis, and the body louse, pe. humanus, have their 37 mt genes on 20 minichromosomes. the pubic louse, pthirus pubis, has its 34 mt genes known on 14 minichromosomes. to understand the process of mt genome ...201526335315
