RESUMO
A parasitological survey on intestinal coccidia, Cryptosporidium sp and Isospora belli, has been carried out in paediatric service of an teaching hospital in the district of Abidjan (Côte d'Ivoire). 130 children under 5 years old suffering from diarrhoea have been enrolled. Direct stools examination method, simplified Ritchie technique and Ziehl Neelsen modified coloration were used for analysis. Moreover, the AIDS serological status of the patients has been determined. The results show that Cryptosporidium sp and Isospora belli were found respectively with a prevalence of 7.7% and 3.9%. Only one case of mixed infestation between theses two parasites has been found. Coccidia were the most recurrent parasites found in diarrhoea after flagellates. Parasitism by coccidia was not related to AIDS serological status of the children. These results point out the necessity to make common coccidian parasitical diagnosis in children under 5 years old suffering from diarrhoea.
