The present internship report was developed in the Microbiology section of LAC of HCM, specifically in the Parasitology subsection. The objectives traced for the internship were to know, to understand and to know to execute all the techniques of diagnosis used in the Laboratory of Clinical Analyses of the HCM and to determine the frequency of intestinal parasites diagnosed in the HCM, during the period of internship. The results of coproparasitological examinations of 1799 persons seen in the Laboratory of Clinical Analyses of the HCM, in the period between June and August 2007, were analysed. 11.2% of the examined samples presented cysts, or eggs of at least one parasite. The results found at the end of the 3-month study showed that protozoa accounted for 70.6% (142) of infections and helminths for 31.4% (59). Of the protozoa, the parasite Giardia lamblia was the most frequent, followed by Entamoeba coli, Endolimax nana and lastly Entamoeba histolytica, with prevalence of 21.9%, 18.9%, 17.9% and 11.9%,< respectively. Of the helminths, the parasite Trichuris trichiura was the most frequent, 16.9%, and the least frequent were Ancylostoma duodenale and Schistosoma mansoni with values of 0.5% and 1%, respectively.
