The Distribution of Intestinal Parasites Detected in the Uludag University Medical Faculty Hospital between 2009-2010

OBJECTIVE: Intestinal parasite infection is still an important public health problem. In this study, patients with various gastrointestinal system complaints presenting at various clinics of the Uludag University Medical Faculty, between 2009-2010 were investigated for intestinal parasites. METHODS: All fecal samples were examined with the formol ethyl acetate sedimentation method for helminth ova and protozoan cysts. For the diagnosis of coccidian protozoa, the modified Ehrlich-Ziehl-Neelsen was used. Trichrome staining was also performed in ambiguous cases. The cellophane tape method was used to detect Enterobius vermicularis egg. The prevalence of intestinal parasites was evaluated with respect to age, gender and the months in which cases were seen. RESULTS: One or more parasites were found in 195 of the 2686 stool samples. The overall prevalence of intestinal parasitic infection rate was 7.3%, and of these patients, 57.95% were female and 42.05% male. Predominant parasites were Giardia intestinalis 3.23%, followed by Entamoeba coli 2.34%, Entamoeba histolytica 0.59%, and Strongyloides stercoralis 0.44%. Enterobius vermicularis eggs were detected by the cellophane tape method in 80 (12.08%) out of 622 patients. The proportion of individuals infected with one parasite was 85.4%, two parasites 12.6%, and three parasites 2.0%. The age group 10-19 years had the highest prevalence of parasites and was predominantly infected with G. İntestinalis (p < 0.001). CONCLUSION: The results of this study emphasized that, even in the Bursa Province with a relatively high level of social hygiene, intestinal parasitic infections are still an important public health problem.
