<b>Objectives</b>
<p>To determine the prevalence and risk factors associated with intestinal parasites in the population of San Juan Cosala, Jalisco, Mexico.</p></sec>
<sec>
<b>Methods</b>
<p>A total of 277 samples from 104 participants were analysed using direct smear, flotation, formaldehyde/ethyl acetate, and modified Kinyoun’s acid-fast stain methods. The Graham method was applied only for samples from children under 12 years of age for the diagnosis of<italic> Enterobius vermicularis.</italic></p></sec>
<sec>
<b>Results</b>
<p>The prevalence of parasite infections in the study population was 77.9% including:<italic> Entamoeba histolytica/E. dispar/E. moshkovskii/E. bangladeshi</italic> (37.5%),<italic> Giardia intestinalis</italic> (11.5%);<italic> commensals: Endolimax nana</italic> (44.2%),<italic> Entamoeba coli</italic> (27.9%),<italic> Chilomastix mesnili</italic> (6.7%) and<italic> Iodamoeba bütschlii</italic>, (2.9%); emerging intestinal protozoans:<italic> Blastocystis</italic> spp. (49%),<italic> Cryptosporidium</italic> spp. (7.7%) and <italic>Cyclospora cayetanensis</italic> (2.9%); and helminths:<italic> Enterobius vermicularis</italic> (18.3%) and <italic>Ascaris lumbricoides</italic> (5.8%). The results also showed that 58.64% of the studied population presented polyparasitism. A significant association was found between protozoan infections and housewives, and houses that were not built with concrete ceilings, brick walls and cement floors (<italic>p</italic> < 0.05).</p></sec>
<sec>
<b>Conclusion</b>
<p>Polyparasitism was observed in over half the study population. The most prevalent parasite was <italic>Blastocystis</italic> spp, whilst the prevalence of helminths was less than that of protozoans. The risk factors for infection to intestinal parasites were being a housewife and not having solid brick, cement and concrete materials for house construction.</p></sec>
