Factors influencing the rearing and maintenance of a laboratory colony of the body louse
. J Econ Entomol.
The body louse
as a vector of reemerging human diseases.
The research also sequenced the genome of a microbe that lives inside the body louse
Moreover, both diseases were dealt with in the same way, by attacking the body louse
and its habitat.
While the technology can be applied to all insect pests, the first application of this research is directed to environmentally friendly and safe control of sheep blowfly and body louse
In the United States, body louse
infestation mainly affects homeless populations.
The body louse
is 1/16 inch long, straw-colored, and moves about the skin surface near the vent, thighs and underside of the body.
Three types of lice infest humans: the head louse (Pediculus humanus capitis), the body louse
(Pediculus humanus corporis), and the pubic louse (Phthirus pubis).
Adult: The adult body louse
is about the size of a sesame seed, has 6 legs, and is tan to greyish-white.
Epidemic typhus is caused by Rickettsia prowazekii and is transmitted when an infected body louse
takes a blood meal and then defecates.
Nicolle decided that the contagious agent must be connected with the old clothes, and he suspected the body louse
, which exists everywhere among human beings where the chance for frequent washing of clothes and body does not exist.
We also collected lice from participants' clothing or body (below the neck) and considered these lice a positive indication of body louse
That's a bit more concise than other small genomes among insects, such as the body louse
's roughly 105 million base pairs.
After a genetic analysis of the louse genome, the researchers learnt that "it was impossible to distinguish the head louse from the body louse
at the genetic level," National Geographic Society reported.
