Abstract
A study of the compatibility between Schistosoma intercalatum from Cam eroon and its potential vectors Bulinus forskalii from Cameroon, Equat orial Guinea, Ivory Coast and Niger has been carried out. As compatibi lity test, the snail infection test, completed by an histological stud y, was used. Snail infection experiments showed that all the populatio ns of B. forskalii we tested are very good potential vectors, with inf ection rates ranging between 76.5 and 93%. The histological study reve aled no defense reaction in the snails, which confirms the perfect com patibility of the B. forskalii populations we studied. In an epidemiol ogical perspective, this study confirms the ever present risk of exten sion of S. intercalatum parasitosis in Africa.
