Scabies is a worldwide disease and a major public health problem in many developing countries, related primarily to poverty and overcrowding. In remote Aboriginal communities in northern Australia, prevalences of up to 50% among children have been described, despite the availability of effective chemotherapy. Sarcoptic mange is also an important veterinary disease engendering significant morbid...

El objetivo del presente estudio fue identificar y evaluar los casos de sarna causada por Sarcoptes scabiei endoparásitos en vicuñas silvestres cautiverio (Vicugna vicugna) la Región Cusco, Perú. Se realizaron raspados lesiones piel se tomaron muestras fecales durante captura chaccus. La frecuencia S. 1.9% (54/2826), siendo 6.1% (48/777) silvestría 0.2% (6/2049) cautiverio. Asimismo, identifica...

Scabies continues to be an important parasitic disease of humans, and other mammals. Suprisingly for a disease that has afflicted humans since antiquity, little is directly known about the basic biology of the parasite, the host-parasite interactions, the host immune response, and host susceptibility. Much more research in these areas is needed if we are to understand fully the occurrence, tran...

To examine outbreaks of mange in raccoon dogs (Nyctereutes procyonoides) with respect to population density, we analyzed camera trap videos, and isolated mites from raccoon dog carcasses. In a camera trapping survey, we categorized the skin condition of raccoon dogs, and used a number of independent videos to calculate the relative abundance index (RAI). The RAI of raccoon dogs with alopecia in...

Human scabies is caused by an infestation of the skin by the human itch mite (Sarcoptes scabiei va. hominis). It is commonly treated with topical insecticides, but the treatment of choice is still controversial. The aim of this study is to compare the efficacy of topical ivermectin vs. permethrin 2.5% cream for the treatment of scabies. In total, 380 patients with scabies were enrolled, and ran...

Host acquired immunity is a critical factor that conditions the survival of parasites. Nevertheless, there is a shortage of data concerning inter-individual immunological inequalities in wild mammals. Sarcoptic mange is a widespread parasitosis that severely affects mammals such as the Iberian ibex (Capra pyrenaica). Despite some work on the subject, the immune response to sarcoptic mange infes...

Ivermectin is increasingly being used to treat scabies, especially crusted (Norwegian) scabies. However, treatment failures, recrudescence, and reinfection can occur, even after multiple doses. Ivermectin resistance has been documented for some intestinal helminths in animals with intensive ivermectin exposure. Ivermectin resistance has also been induced in arthropods in laboratory experiments ...
