University of Illinois at Urbana-Champaign A new study seeks to determine how one parasitic species can give rise to two drastically different outcomes in its host: The human body louse (Pediculus humanus) can transmit dangerous bacterial infections to humans, while the human head louse (also Pediculus humanus) does not. A report of the new study appears in the journal Insect Molecular Biology. "Body louse-transmitted diseases include trench fever, relapsing fever and epidemic...

Study explores whole-body effects of toxic drug A new study in fruit flies offers a broad view of the potent and sometimes devastating molecular events that occur throughout the body as a result of methamphetamine exposure. The study, described in the journal PLoS ONE, tracks changes in the expression of genes and proteins in fruit flies (Drosophila melanogaster) exposed to meth. Unlike most studies of meth, which focus on the brain, the new analysis looked at molecular changes throughout the...

Like an unwelcome houseguest or itinerant squatter, the human body louse shows up when times are bad and always makes them worse. Now a multi-institutional team reports that it has sequenced the body louse genome, an achievement that will yield new insights into louse "“ and human "“ biology and evolution. The study, which also sequenced the genome of a microbe that lives inside the body louse, appears in Proceedings of the National Academy of Sciences. Thanks to its tenacity, the...
