Møller, University of Copenhagen) Macroscopically visible trophonts (white spots) on skin or fins is often the basis for a tentative diagnosis of I. multifiliis infection.

Vernacular terms to describe diseases caused by mites include scab, mange, and scabies. Mites and ticks have substantially different biology from, and are classed separately from, insects (the class Insecta). Mites of domestic animals cause important types of skin disease, and some mites infest other organs. Diagnosis of mite infestations can ...
