Cryptosporidium spp and Isospora belli parasites are emerging that represent the fourth leading cause of diarrhea worldwide, mainly in children and in immunocompromised patients. Acute or chronic diarrhea occur depending on the patient's age, nutritional status and immunological factors associated with adverse health. The diagnosis is made by direct visualization in feces Neelsen stain Zelh Kinyou modified or intestinal biopsy and the presence of protozoa in the crypts and villous atrophy according to the degree of infestation. We report the case of preschool age 2, eutrophic immunocompetent, belonging to low socioeconomic levels, with self-limiting episodes of acute watery diarrhea, frequent abdominal pain and bloating. The intestinal biopsy revealed villous atrophy and simultaneous infestation by Cryptosporidium spp and Isospora belli Kinyou confirmed by staining in feces, while discarding also Food Allergy, Celiac disease and immunodeficiencies. The purpose of this case to alert about the need to include in the study protocol of chronic diarrhea, the search for spore-forming protozoa by special staining in feces, a noninvasive and simple method, not routinely requested.
