This study aimed to determine the frequency of infection by intestinal protozoa diagnosed in patients from a clinical analysis laboratory in Maceió, Alagoas, Brazil. This was a retrospective descriptive study, using a database of stool examination results from July to December 2015. The study population consisted of males and females of all ages, from the greater area of Alagoas. Data on epidemiological variables such as age and gender were obtained using a collection instrument. Protozoan species were identified from stool examinations. Results on the prevalence of intestinal parasites are described as simple and relative frequencies. We examined a total of 1277 stool samples, of which 12.69% were positive for one or more protozoa. 43.83% were from men and 56.17% were from women. Endolimax nana was the most prevalent (59.22%) protozoan species followed by Entamoeba coli (23.45%). Although non-pathogenic, they indicate fecal contamination of drinking water. The highest number (23.46%) of infected individuals was observed among children in the 0 to 11 years age group. A high prevalence (93.83%) of monoparasitism was noted. We concluded that there was a high frequency of infection and a high prevalence of E. nana. Infections were more common in women than in men. Our results emphasize the need for preventive measures to control intestinal parasitic infections.
