Abstract
Endolimax nana, is one of the least described non-pathogenic intestinal protozoa that is distributed throughout the world. Transmission occurs by the fecal-oral route. The main clinical manifestations of human infection with this protozoan are symptoms of the gastrointestinal tract. We have described a clinical case of infection in an 8-year-old child. When conducting a coprological study, cysts of E. Nana were found and a course of treatment with metronidazole was prescribed. In the control study of stool samples, a negative result was obtained, clinical manifestations disappeared.
