Materials and Methods: 109 fecal samples of people of both genders from 1 to 72 years processed by the Richter technique were examined. From the sediment, two slides were prepared for each sample per sample and stained by the Kynioun method. The slides were examined under light microscopy at 1000X magnification. Results: From the 109 fecal samples examined, nine samples with oocysts of Cryptosporidium spp. were found, corresponding to a prevalence coefficient (PC) of 8.26%. Only children under eight years old were infected. Conclusion: The results of this research were the basis for sanity orientation and adequate drug intervention. The results revealed the need to adapt health services in order to improve the living conditions of the Potiguar community.
