[Epidemiology of human urban schistosomiasis in Bamako in Mali (the case of the "populous" quarter of Bankoni)].

From may 1989 to january 1990, we have studied parasitologic index in snails population, stools and urines examination in children (1-15 years) in one of the greatest "spontaneous" quarter of Bamako. 584 stools samples and 563 urines were tested. 4.717 snails were captured during six months. From all these data, we conclude that in Bankoni S. haematobium is mesoendemic (36.6%) and S. mansoni hypoendemic (3.4%). B. truncatus is the most important host for urogenital schistosomiasis. The two seasonal revers (Tienkole and Bankoni) are unfavourable to B. pfeifferi's production. B. globosus and B. forskalii are not frequent in this suburban area. This investigation, shows that a selective mass treatment with praziquantel is the better public health care strategy in Bankoni quarter.
