[Contribution to the knowledge of intestinal protozoa infestation in the hospital population of Barcelona (author's transl)].
This report concerns the analysis of 650 fecal samples submitted for parasitic investigation to the Microbiology Service of the Hospital de la Santa Creu i Sant Pau of Barcelona. The samples were analyzed by the technique of fixation and direct observation of Sapero and Lawless (MIFD), and with the biphasic concentration method of Blagg et al (MIFC). Intestinal protozoa were detected in 183 samples (28.2%), with a total of 232 protozoosis uncovered. The specific analysis gave the following results: Giardia lamblia, 10.9%; Dientamoeba fragilis, 7.8%; Entamoeba coli, 4.6%; Endolimax nana, 4.5%; Entamoeba hartmanni, 4.0%; Iodamoeba buetschlii, 2.9%; Entamoeba histolytica, 0.7%; Chilomastix mesnili, 0.2%; Trichomonas hominis, 0.2%. The results obtained by the two methods have been compared, observing the highest number of positive results with MIFD technique. Especial mention is made of the higher incidence of Dientamoeba fragilis in samples positive for Oxyuris further studies being needed to establish the basis for the relationship between both species of parasites.
