Crab or Pubic Lice

Human Skin Parasites

Crab or pubic lice are shorter and broader than the other two types of human lice. The general life style is essentially the same as the head louse, except that the crab louse is generally found on pubic and armpit hair, and less commonly facial hair, such as eye brows and eye lashes. It can survive only short periods off the host, and is transmitted primarily by human-to-human contact, particularly sexual contact. This louse is not known to transmit any disease causing pathogens.
