Resistance of head lice to insecticides with a neurotoxic mode of action, such as permethrin and malathion, is increasing in incidence and geographic extent. As a consequence, physically acting pediculicidal products have emerged. Dimeticones are synthetic silicone oils of low surface tension and can therefore coat most surfaces, thus also killing head lice (Pediculus humanus capitis) by physic...

Analyses of a unique database containing sea lice records over an 11 year period provide evidence of changing infestation patterns in Scotland. The data, collected from more than 50 commercial Atlantic salmon farms, indicate that both species of sea lice commonly found in Scotland, Lepeophtheirus salmonis and Caligus elongatus, have declined on farms over the past decade. Reductions for both sp...

BACKGROUND Methods for the diagnosis of Pediculus humanus var. capitis are controversial and most studies are based on direct visual exam. OBJECTIVE The objective of this study was to compare the diagnosis efficacy of both direct visual exam and the use of a metal microchanelled fine-toothed comb. METHODS 946 children and teenagers 4 to 19 years of age were examined. Each individual's hair ...

Background: Head lice infestation constitutes a serious health problem in marginalized areas where schoolchildren and their families are mostly affected. This study aimed to compare 3 lice control protocols approved by Ministry of  Health and Medical Education, based on 1% permethrin shampoo, 4% dimethicone lotion and (1:1) vinegar wet combing for the treatment of outpatients of Imam Reza Hospi...

Specific chewing lice from European bison and some selected species of common European ungulate mammals – cattle, horses, goats, roe deer, red deer, were examined. The faunistic research was on four species of chewing lice, including Bisonicola sedecimdecembrii from European bison (prevalence – 46%, mean intensity – 11 specimens), Bovicola bovis from cattle (29%, 5), Bovicola caprae from goat (...

Incidence of carbapenem-resistant Acinetobacter baumannii is rising in several parts of the world. In Africa, data concerning this species and its resistance to carbapenems are limited. The objective of the present study was to identify the presence of A. baumannii carbapenem-resistant encoding genes in natural reservoirs in Senegal, where antibiotic pressure is believed to be low. From October...

Pubic lice (Pthirus pubis) maintain a worldwide parasitic population infesting two to over 10 percent of human populations, continuing a presence that has been constant since early evidence 10,000 years ago. Outbreaks in the 1970s have been recorded, but incomplete records preclude description of a definitive population cycle. Current levels of infestation in a US college student population wer...
