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.
