Human coccidiosis caused by Isospora belli. A second case observed in Belgium.

In 1962, the first case of human coccidiosis caused by Isospora belli was reported from Belgium 1. It occurred in a patient of Armenian origin who had lived in Belgium from childhood and in whom 1sospora belli oocysts were discovered in the stools while the patient was suffering from persistent diarrhoea which had started when he was travelling in Iran. Unfortunately, the patient was lost sight of later on. The present paper records a second case of the same parasitism, also observed in Belgium, which had probably been contracted in Congo.
