Which is the correct scientific name for body lice?

• A. Pediculus humans capitis.
• B. Pediculus humans pubis.
• C. Pediculus humanus corporis.
• D. Sarcoptes scabiei.

Answer: (C)

The question tests your ability to match a parasite’s scientific name to its specific human infestation. Lice that feed on humans come in three main forms, each with a distinct subspecies name that reflects where they live: head lice on the scalp, body lice on clothing and the body, and pubic lice in the pubic area. The body louse is Pediculus humanus corporis, with “corporis” indicating the body. This differentiates it from the head louse, Pediculus humanus capitis, and from the pubic louse, Pthirus pubis. The option named Sarcoptes scabiei is a different parasite (the scabies mite) and not a louse at all.
