ASTUDILLO, Osvaldo Germán  and  BAVA, Amadeo Javier. Prevalence of intestinal parasites in Infectious Diseases Hospital “Dr. Francisco Javier Muñiz”. Acta bioquím. clín. latinoam. [online]. 2017, vol.51, n.4, pp.681-686. ISSN 0325-2957.

The results obtained during the period between January and December 2016 of the fecal samples and anal sclerosis, were submitted retrospectively to the laboratory of the Parasitology Section of the Hospital of Infectious Diseases “Francisco Javier Muñiz” of the City of Buenos Aires. The results of 1253 parasitological studies of fecal matter and of 268 gauzes anal swabbing, corresponding to 1207 patients, were taken into account. The results of the samples from 432 patients were left out, and none of their data was evaluated. Fecal samples were positive in 288 (22.98%) cases, while 33 (12.31%) were positive for the presence of Enterobius vermicularis eggs. The presence of Blastocystis sp. was detected in 194 (17.1%) patients, followed in order of frequency by Entamoeba coli (51. 4.5%), Giardia lamblia (47. 4.1%) and Endolimax nana (32. 2.8%). The finding of coccidiosis showed a prevalence of 1.2% (n = 14) for Cryptosporidium sp. and 1.3% (n = 15) for Cystoisospora belli. When the incidence of parasitosis was evaluated according to the age of the patients, the existence of significant differences between proportions of parasitized patients with ages less than or equal to 15 years and older was observed. On the other hand, no significant differences were found between the proportions of women and men with positive coproparasitological studies. The present study, performed with a simple methodology, within the reach of low complexity laboratories, has shown that the number of genera and species found in the analyzed samples presents spatial heterogeneity, with the highest values represented by Blastocystis sp., followed by Giardia lamblia and non-pathogenic amoebae, as well as an important prevalence of coccidia in fecal samples of the population studied, associated with AIDS patients. Further and more complete studies, including a greater amount of data of the evaluated patients, will facilitate a better knowledge of the coproparasitosis present in the assisted population in the Muñiz Hospital.
