Description
Summary:The goal of this study was to present an overview of human infections with Capillaria philippinensis, a new emerging parasite in Upper Egypt. The study included 21 inpatients who had been admitted to the Assiut University Hospital. Patients suffered from intermittent abdominal pain, borborygmi, chronic diarrhea lasting for several weeks, and marked weight loss. Hypoalbuminemia and low serum levels of potassium, calcium, and sodium were detected in most patients. A stool examination was performed using direct smears and the formalin-ether concentration method. Intact adult worms and/or eggs were evaluated using a light microscope and processed for scanning electron microscopy. The examination by light microscopy illustrated the general morphology of different stages. Using scanning electron microscopy, intestinal villi were found partially covering the cuticle of the adult worms, which provided evidence for the invasion of adult worms into the jejunal mucosa. Two distinct types of eggs, thick-shelled and thin-shelled, were identified and measured.
