Abstract: We carried out a comparative study of intestinal parasites in 1.200 individuals from four rural and two urban populations located at Cumana, Sucre State, Venezuela. After previously obtaining their informed consent, we collected fecal samples that were processed by a coproparasitological examination, qualitative Kato’s method, Ritchie, Ziehl-Neelsen stain, and agar culture. Results showed that 77.8% of the individuals were parasitized, and that there were differences according to the type of population being evaluated (χ²=136.1; p<0.001). In both rural an urban areas predominated polyparasitism and monoparasitism respectively, finding significant differences (χ²=136.1; p<0.001). In both areas it was more frequent in females. Age showed a significant association and parasites were most prevalent in children 0 to 7 years old in rural areas and 8 to 14 years old in urban areas (χ²=22.6; p<0.004). More species were diagnosed in rural areas and Blastocytiis spp. (protozoa) and Trichuris trichuira (helminth) were the most prevalent. Blastocyttis spp. was associated with other protozoa. Associated helminths were T. trichuria and Ascaris lumbricoides in both types of populations. The high frequency of intestinal parasites in the populations evaluated shows the exposure of the inhabitants to common contamination mechanisms.
