Presence of the knockdown resistance (kdr) mutations in the head lice (Pediculus humanus capitis) collected from primary school children of Thailand

PLoS Neglected Tropical Diseases, 2020
Human head lice are blood-sucking insects causing an infestation in humans called pediculosis capitis. The infestation is more prevalent in the school-aged population.

Efficacy and Safety of a Water-Based Head Lice Lotion: A Randomized, Controlled, Investigator-Blinded, Comparative, Bicentric Study

Dermatology and Therapy, 2018
Introduction Silicones (e.g., dimethicone) are effective and safe alternatives to insecticides for the treatment of head lice. However, silicones are lipophilic substances and do not only leave the hair greasy but they are also difficult to wash out.

Genotyping of human lice suggests multiple emergencies of body lice from local head louse populations. [PDF]

PLoS Neglected Tropical Diseases, 2010
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.

First evidence of the mutations associated with pyrethroid resistance in head lice (Phthiraptera: Pediculidae) from Honduras

Parasites & Vectors, 2020
Background The human head louse, Pediculus humanus capitis , is a cosmopolitan blood-sucking ectoparasite affecting mostly schoolchildren in both developed and developing countries.

Impacts of salmon lice on mortality, marine migration distance and premature return in sea trout

, 2020
Brown trout Salmo trutta (L.) is a facultative anadromous species, where a portion of individuals in populations with access to the sea perform migrations to use the richer feeding resources.

First report of reduced sensitivity towards hydrogen peroxide found in the salmon louse Lepeophtheirus salmonis in Norway

Aquaculture Reports, 2015
Reduced sensitivity towards chemotherapeutants in the salmon louse Lepeophtheirus salmonis (Krøyer) is an increasing problem for the fish farming industry.

Caligus rogercresseyi acetylcholinesterase types and variants: a potential marker for organophosphate resistance

Parasites & Vectors, 2018
Background Control of the sea louse Caligus rogercresseyi in the Chilean salmonid industry is reliant on chemical treatments. Azamethiphos was introduced in 2013, although other organophosphates were previously used.

Evidence that head and body lice on homeless persons have the same genotype. [PDF]

PLoS ONE, 2012
Human head lice and body lice are morphologically and biologically similar but have distinct ecologies. They were shown to have almost the same basic genetic content (one gene is absent in head lice), but differentially express certain genes, presumably ...
