To determine the prevalence of intestinal parasites in a sample of residents from the rural community, “La Carolina,” in the State of Bolivar, Venezuela. Material and Methods: A fecal sample from each participating inhabitant was analyzed using techniques of direct examination, Kato, spontaneous sedimentation and Kinyoun staining. Of the 115 people tested, 97 were parasitized with a prevalence of 84.3 %. With regard to age, all groups were affected equally (² = 0.812 df: 6 p > 0.05), although the largest number of cases (52 people) were found in the group of 0-9 years. Both sexes were equally affected (p> 0.05). The study found 54.6% polyparasitism and 45.4% monoparasitism. Nine species of intestinal parasites were diagnosed. The group of protozoa and chromists were more prevalent (94.8%) than helminths. Blastocystis spp. was the most prevalent parasite with 65.2 %. No intestinal coccidia were diagnosed. The most common parasitic associations were between protozoa, emphasizing Blastocystis spp. with Giardia intestinalis (22.6%) and Blastocystis spp. with Endolimax nana (15.1%). An important prevalence of intestinal parasites (84.3%) was determined in the rural community, “La Carolina,” State of Bolivar.
