Preliminary Molecular Characterizations of Sarcoptes scaibiei (Acari: Sarcoptidae) from Farm Animals in Egypt

Little is known about the genetic diversity of Sarcoptes scabiei mites in farm animals in Egypt. In this study, we characterized S. scabiei in 25 skin scrapes from water buffalo, cattle, sheep, and rabbits at the nuclear marker ITS2 and mitochondrial markers COX1 and 16S rRNA. Sequences of the ITS2 showed no host segregation or geographical isolation, whereas those of the mitochondrial COX1 and...

Genetic epidemiology of Sarcoptes scabiei in the Iberian wolf in Asturias, Spain.

BACKGROUND During the last decades, attempts have been made to understand the molecular epidemiology of Sarcoptes scabiei, and to detect and clarify the differences between isolates from different hosts and geographic regions. Two main phenomena have been described: (i) host-taxon derived-Sarcoptes mite infection in European wild animals (revealing the presence of three separate clusters, namel...

Transcriptome-microRNA analysis of Sarcoptes scabiei and host immune response

Scabies is a parasitic disease, caused by the mite Sarcoptes scabiei, and is considered one of the top 50 epidemic diseases and one the most common human skin disease, worldwide. Allergic dermatitis, including an intense itch, is a common symptom, however diagnosis is difficult and there is currently no effective vaccine. The goal of this study was to examine the immune interaction mechanism of...

Experimental infection of the domestic donkey (Equus asinus asinus) with a goat strain of Sarcoptes scabiei, and treatment with ivermectin.

Donkeys were experimentally infected with Sarcoptes scabiei from goats, proving that this mite is not completely host specific. The lesions produced on the donkeys were characterized by extensive areas of alopecia, covered with thin crusts and bran-like scales. The skin had many excoriations but showed no cracks or fissures. Skin scrapings from the experimental lesions in donkeys contained nume...
