Sarcoptes Scabiei

Sarcoptes scabiei or the itch mite is a parasitic arthropod that burrows into skin and causes scabies. Not only humans are affected but also animals such as wild and domesticated dogs and cats in which it is one cause of mange. Also affected in the wild are ungulates, boars, bovids, wombats, koalas, and great apes.

The Italian biologist Diacinto Cestoni showed in the 18th century that scabies is caused by the mite Sarcoptes scabiei, variety hominis. The disease produces intense, itchy skin rashes when the impregnated female tunnels into the stratum corneum of the skin and deposits eggs in the burrow. The larvae, which hatch in 3–10 days, move about on the skin, moult into a nymphal stage, and then mature into adult mites. The adult mites live 3–4 weeks in the host's skin.
