Abstract

We are hereby reporting a case where the eggs and adults of the mold mites; Tyrophagus putrescentiae (Shrank) and the trophozoites of Blastocystis sp. were found in stool of three years old child from Minia City, Egypt. Intestinal mite infection was diagnosed after repeated identification of mite’ stages from six consecutive stool samples to exclude the possibilities of contamination and spurious infection. The patient was suffering from severe colicky abdominal pain and burning sensation around the anus one month ago. All other members of his family were having the same acarine in their feces, but were all symptomless. The patient was treated with ivermectin 200 µg/kg body weight once every 10 days for three doses. His cure indicated that he was having asymptomatic blastocystosis.

Highlights

House dust mites represent a large group of subclass Acari, belonging to the suborder Acaridida of the order Acariformes
Intestinal acariasis is rather an uncommon human disease; the first case was reported by Hinman and Kampmeier (1934) which was caused by Tyroglyphus longior Gervals
Realizing the identity of the causative mite was followed by successful treatment with ivermectin as this broad spectrum antiparasitic drug was suggested by Li (2000) to be the drug of choice for human intestinal acariasis
