PATHOLOGY

Detailed explanation-1: -Although the term ectoparasites can broadly include temporarily blood-sucking arthropods such as mosquitoes, this term is generally used more narrowly to refer to pathogens such as ticks, fleas, lice, parasitic flies and mites that attach or burrow into the skin and remain there for relatively long periods of time2.

Detailed explanation-2: -Ectoparasites include scabies (Sarcoptes scabiei), the common bed bug (Cimex lectularius), fleas, and lice, including the body louse (Pediculus humanis), pubic louse (Phthirius pubis), and head louse (Pediculus humanus capitis).

Detailed explanation-3: -An ectoparasiticide is an antiparasitic drug used in the treatment of ectoparasitic infestations. These drugs are used to kill the parasites that live on the body surface. Permethrin, sulfur, lindane, dicophane, benzyl benzoate, ivermectin and crotamiton are well known ectoparasiticides.
