This is a photomicrograph of the scabies mite. This animal burrows in the skin, depositing both eggs and feces. Scabies infestation causes intense itching (pruritus) which leads to scratching and damage of the skin (excoriation). The infestation may last for years without treatment and has been called the "seven year itch".
