Abstract

The susceptibility of 13 different B. forskalii strains from Zaire, Cameroun, Gabon, Senegal, Rhodesia and Tanzania and B. reticulatus wrighti Aden has been tested to infection with Schistosoma intercalatum from Cameroun. The most common prepatent period was 23–28 days.

B. forskalii from Zaire, Cameroun and Gabon were excellent intermediate hosts with infection rates varying from 59–0 to 97–4% and with very low death rates, 0-28-4%. The strains from Senegal and Rhodesia had infection rates from 500 to 58.4%. B. forskalii from Tanzania was refractory. 53.0% of the exposed B. reticulatus wrighti was infected. The total cercariae production per snail varied from 1000–11000. The duration of the infection varied from 8 to 174 days.
