Abstract :

Background: Intestinal protozoa, including coccidia, cryptosporidia, isospororidia, cyclosporidia and microsporidia are opportunistic parasites usually incriminated in gastroenteritis. The diagnosis of these parasites in individuals presenting with an acute diarrhea is usually conducted very late, though their presence in stools might constitute a warning signal of a weakened immune system.

Objectif: This study aimed at establishing the profile of intestinal parasites among individuals suffering from gastroenteritis in Yaoundé (Centre Region, Cameroon).

Methodolody: All patients suffering from gastroenteritis and referred to the "Centre Pasteur du Cameroun" for biological examinations of their stool samples were included in this study. The biological diagnosis consisted in concentration methods including the Kato Katz technique, the formalin-ether method, and the modified Ziehl Neelson staining technique.

Results: A total of 317 patients, including 166 (52%) males, aged 3 months to 81 years old (median age: 30 years, Interquartile range: 8 - 45 years) provided stool samples for analyses. Various parasites groups were found after stool examinations, including coccidia (10.1%; 95% CI: 7.0 - 14.0%), flagellates (2.8%; 95% CI: 1.3 - 5.3%), amoeba (15.5%; 95% CI: 11.9 - 19.8%) and helminths (1.0%; 95% CI: 0.2 - 2.7%). The prevalence of protozoa among all examined patients was 27.8% (95% CI: 0.22-0.33), including Cryptosporidium parvum (9.4%), Isospora belli (0.9%), Giardia intestinalis (1.6%), Chilomastix mesnili (1.2%), Trichomonas intestinalis (0.3%).

Conclusion/Recommandation:This study reveals that 30% of patients suffering from gastroenteritis harbored intestinal parasites, most of them being protozoa. The early diagnosis of these intestinal parasites could help improving the management of individuals suffering from a gastrointestinal infection by guiding practitioners' therapeutic recommendations, and therefore reduced the morbidity and mortality associated.
