Scabies Mite (Microscopic view of burrow)
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, while males are slightly smaller.
Natural Habitat
The epidermis (outer layer) of human skin, particularly in folds like between fingers, wrists, armpits, and genitals.
Diet & Feeding
They feed on dissolved human tissue and skin cells, but do not drink blood.
Behavior Patterns
The female mite burrows into the upper layer of the skin to lay eggs, creating the characteristic squiggly, raised lines or 'burrows' often seen in magnified images. This causes intense allergic itching, especially at night.
Risks & Benefits
Risks: Highly contagious skin infestation causing intense itching (pruritus) and rash. Scratching can lead to secondary bacterial infections like impetigo or cellulitis. Benefits: None.
