ShareCompartir
Stool specimens were collected from residents of the Peruvian Amazon rain forest to evaluate the burden of helminth infections. Stool was collected and processed via Kato Katz at a laboratory in Cusco, Peru. The objects in Figures A-C were observed in high numbers (1,500 eggs/gram of stool) from a 54-year-old male patient. The objects measured on average 65 micrometers long by 33 micrometers wide. Clinical examination of the patient revealed that he did not have eosinophilia or elevated liver enzymes.
