Sarcoptes scabiei
Sarcoptes scabiei
Sarcoptes scabiei (pronunciation: /sɑːrˈkɒptiːz ˈskeɪbi.aɪ/), commonly known as the itch mite, is a parasitic mite that causes scabies in humans and other animals.
Etymology
The name Sarcoptes is derived from the Greek words sarkos (meaning flesh) and koptein (to cut), referring to the mite's ability to burrow into the skin. Scabiei is the Latin word for scabies, which means to scratch.
Description
Sarcoptes scabiei are microscopic, oval-shaped mites with eight legs. They are approximately 0.3-0.4 mm long and are barely visible to the naked eye. The female mites burrow into the skin to lay eggs, causing intense itching and a pimple-like rash.
Life Cycle
The life cycle of Sarcoptes scabiei involves four stages: egg, larva, nymph, and adult. The entire life cycle takes place on the host and lasts for approximately two to three weeks.
Transmission
Sarcoptes scabiei is primarily transmitted through direct, prolonged skin-to-skin contact with an infested person. It can also be transmitted indirectly through contact with infested clothing, bedding, or furniture.
Treatment
Treatment for Sarcoptes scabiei infestation involves medications that kill the mites and their eggs. These are usually applied as creams or lotions to be applied all over the body. It is also important to wash all clothing, bedding, and towels used by the infested person.
