Tyroglyphus longior has been recovered from the stools of two patients with diarrhea and in one of these cases, clinical, laboratory and autopsy evidence have been found that these mites were the probable etiological agents responsible for the gastro-intestinal symptoms.

These acarines have been recovered from the feces of dogs with an intense diarrhea and the elimination of mites from the diet has caused the disappearance of all evidence of intestinal irritation. It is believed that the mites are unable to establish residence in the alimentary tract for very long periods and that the production of symptoms is due to their long continued ingestion in food. It is not known whether the symptomatology is due to a toxic substance elaborated by the mite, whether it is an allergic manifestation or if it is due to mechanical irritation.

Living mites and their eggs have been recovered from the feces of experimental dogs artificially infected with these organisms.

A summary of the literature of cases of human infestation by mites in the skin, intestines and urogenital tract is presented.
