Prevalence of intestinal opportunistic parasites infections in the University hospital of Bobo-Dioulasso, Burkina Faso

Abstract

Background: Gastrointestinal parasites infections are widespread in Africa and their prevalence infections vary from country to country. This study aimed at assessing the prevalence of opportunistic intestinal parasites infection and other gastrointestinal parasites infection among patients attending the laboratory of Parasitology and Mycology of the University Hospital Souro Sanou of Bobo-Dioulasso. Methods: A hospital cross-sectional based study was conducted from April to August, 2012. Participants were persons whom parasitological examination of stools has been prescribed by a clinician. The stools examination methods included direct wet saline examination, lugol's iodine staining technique, formol-ether concentration and modified Ziehl-Neelsen staining. We recorded age and sex information for each patient. Results: The overall prevalence of intestinal parasite infections was 65.3% (190/291). Majority of the parasitic infections was waterborne (64.3%) consisting of high prevalence of Cryptosporidium sp. (26.5%) and Entamoeba histolytica/dispar (23.4%). The prevalence of opportunistic parasites was 28.9% and Cryptosporidium sp. was the most prevalent species followed by Blastocystis sp. (1.0%), Cyclospora sp. (0.7%) and Isospora belli (0.7%). The prevalence of intestinal helminthes was 1.7%. Conclusions: The prevalence of intestinal parasitism in general remains high in Bobo-Dioulasso requiring the establishment of adequate diagnostic techniques, treatment and prevention.
