Scabies Mite (Burrow/Rash)
Scientific Name: Sarcoptes scabiei var. hominis
Order & Family: Order: Sarcoptiformes, Family: Sarcoptidae
Size: Microscopic; females are 0.30–0.45 mm long and 0.25–0.35 mm wide; males are slightly smaller.
Natural Habitat
The epidermis (upper layer) of human skin, particularly in areas like webbing between fingers, wrists, elbows, armpits, and waistlines.
Diet & Feeding
Human skin cells and lymph fluid found within the epidermis.
Behavior Patterns
As an obligate parasite, adult females burrow into the upper layer of the skin to lay eggs, creating tiny, raised, serpentine lines (burrows). The cycle creates an intense allergic reaction (itching) in the host, usually worse at night.
Risks & Benefits
Risks: Causes scabies, an intensely itchy skin infestation. Constant scratching can lead to secondary bacterial infections like impetigo or eczema. Highly contagious through prolonged skin-to-skin contact. Benefits: None known.
