Pink salmon, Oncorhynchus gorbuscha, are the most abundant wild salmon species and are thought of as an indicator of ecosystem health. The salmon louse, Lepeophtheirus salmonis, is endemic to pink salmon habitat but these ectoparasites have been implicated in reducing local pink salmon populations in the Broughton Archipelago, British Columbia. This allegation arose largely because juvenile pin...

ous and extensive outbreaks of typhus during the war in various countries, both of the West and the East, led to intensive study of this disease and its vector the louse. This study led, not unnaturally, to the recognition of other clinical entities, resembling the classical typhus in some of its manifestations, but obviously existing under conditions which precluded the usual role of the louse...

OBJECTIVES Head lice (Pediculus humanus capitis) are a major irritant to children and their parents around the world. Each year millions of children are infested with head lice, a condition known as pediculosis, which is responsible for tens of millions of lost school days. Head lice have evolved resistance to many of the currently used pediculicides; therefore, an effective new treatment for h...

An opportunistic survey of louse distribution upon the peacock Pavo cristatus was undertaken following a cull of 23 birds from an English zoo. After complete skin and feather dissolution, 2 species of lice were retrieved, Goniodes pavonis and Amyrsidea minuta. The distribution of both louse species could be described by a negative binomial model. The significance of this is discussed in relatio...

We report an imported case of louse-borne relapsing fever in a young adult Eritrean refugee who presented with fever shortly after arriving in Switzerland. Analysis of blood smears revealed spirochetes identified as Borrelia recurrentis by 16S rRNA gene sequencing. We believe that louse-borne relapsing fever may be seen more frequently in Europe as a consequence of a recent increase in refugees...
