Diseases caused by acari (ticks and mites)

Abstract

The subclass Acari includes ticks (order Ixodida) and mites (Mesostigmata, Trombidiformes, Sarcoptiformes, several other orders). Ticks can transmit several pathogens and cause direct damage (e.g., blood depletion, skin lesions, and paralysis) to their host. Mites can cause lesions in the skin (e.g., mange-causing mites) of their hosts and affect their respiratory tract. Some free-living mites and their discarded cuticles can be aspired by and cause allergic reactions in humans. Systematic control of ticks on domestic animals and, eventually, in the environment is required. Control of mange-causing mites is usually done by treating affected patients and by avoiding sharing of clothes. Cleaning of houses, carpets, and bedclothes and reduction on humidity are efficient for the control of dust mites.
