Human Pathogens in Body and Head Lice
نویسندگان
چکیده
Using polymerase chain reaction and sequencing, we investigated the prevalence of Rickettsia prowazekii, Bartonella quintana, and Borrelia recurrentis in 841 body lice collected from various countries. We detected R. prowazekii in body lice from Burundi in 1997 and in lice from Burundi and Rwanda in 2001; B. quintana infections of body lice were widespread. We did not detect B. recurrentis in any lice.

Lice, Humans, and Microbes
Lice are small, wingless, minor ectoparasites of mammals and birds. More than 540 blood-sucking lice (Phthiraptera: Anoplura) have been described with each host having its own type of louse, suggesting the cospeciation of the lice species with their host. Among these, two lice species from two different genera infest humans: Pediculus humanus and Phthirus pubis (pubic “crab” l...
متن کاملDetection of bacterial pathogens including potential new species in human head lice from Mali
In poor African countries, where no medical and biological facilities are available, the identification of potential emerging pathogens of concern at an early stage is challenging. Head lice, Pediculus humanus capitis, have a short life, feed only on human blood and do not transmit pathogens to their progeny. They are, therefore, a perfect tool for the xenodiagnosis of current or recent human i...
متن کاملWhat's in a name: the taxonomic status of human head and body lice.

Despite the obvious impact these lice have had on their human hosts, it is unclear whether head and ...

Therefore, this study aimed to study eco-epidemiological factors of head lice in 10-12 year-old ...
متن کاملGenotyping of Human Lice Suggests Multiple Emergences of Body Lice from Local Head Louse Populations
BACKGROUND Genetic analyses of human lice have shown that the current taxonomic classification of head lice (Pediculus humanus capitis) and body lice (Pediculus humanus humanus) does not reflect their phylogenetic organization. Three phylotypes of head lice A, B and C exist but body lice have been observed only in phylotype A. Head and body lice have different behaviours and only the latter hav...
