BRACHO MORA, Angela et al. Prevalence of enteroparasites and IgG antibodies anti-Entamoeba histolytica in the indigenous community of Toromo, Zulia State, Venezuela. Rev. Soc. Ven. Microbiol. [online]. 2013, vol.33, n.2, pp.151-156. ISSN 1315-2556.

In order to determine the seroprevalence of antibodies against Entamoeba histolytica and intestinal parasites in the indigenous community of Toromo, Zulia state, Venezuela, 69 individuals of both sexes, from 1 to 60 years of age were studied during the year 2012. Stool and serum samples were collected. Microscopic study of fecal specimens was carried out by saline solution dilution, Lugol staining, formol-ether concentration and Kinyoun’s stain. For determination of anti-Entamoeba histolytica IgG antibodies, a commercial ELISA technique in serum was used; 98.6% of the population were parasitized, predominating the polyparasitism (88.24%) and finding up to 10 different parasite species were associated. The main parasitic species found were: Ascaris lumbricoides (65%), followed by Blastocystis sp. (59%). Entamoeba histolytica/dispar/moshkovskii was detected by microscopy in 25 individuals (36% prevalence), which included a case of infection by Entamoeba histolytica as hematophagous trophozoites were observed. A seroprevalence of 83% for IgG anti-Entamoeba histolytica antibodies in the individuals studied was found. According to the results it is concluded, that there is a high seroprevalence of antibodies against E. histolytica, as well as a high prevalence of intestinal parasites in the indigenous population studied.
