A very important finding in this study was the high percentage (82.8 %) of persistent diarrhea reported by 29/35 patients or consigned in their clinical history. Besides parasites, no other bacterial or viral causes were investigated. The diarrhea was not characterized in dur- ation or daily frequency of bowel movements; stool characteristics related only to those observed in one rou- tine sample received in the PS. Although the spectrum of intestinal enteropathy commonly affecting people liv- ing in developing countries are multifactorial, the patient epidemiologic history and relevant clinical findings may provide important clues of likely etiology. Complaints of diarrheal disease are a commonly shared co-morbidity aspect in HIV/AIDS patients, in malignancy, in other intestinal parasitosis as severe trichuriasis, severe hookworm infection, balantidiasis and giardiasis, cystoisosporiasis, and alcoholism [30–33]. Gastro- intestinal presentations of chronic S. stercoralis infec- tion are non-specific and include diarrhea, nausea, anorexia, weight loss that may wax and wane before spontaneous resolution or proceed to hyperinfection
