| Résumé : | In the case of schistosomiasis, as in all other diseases caused by a parasite with an intermediate host, there can exist, theoretically, two preventive measures, the one directed against the parasite and the other against the intermediary host. The choice of one or the other of these measures or the simultaneous use of both depends, in practice, on local conditions. Now, practice has shown that the definitive suppression of the intermediary host is very hard to accomplish. Among the various measures employed or proposed against snails, are the numerous molluscicides that have first been tried in vitro, and next on limited collections of water. Our long observations on the spot in different parts of Africa, showed the great resistance of snails to definitive or long-term extermination. We have confined ourselves, in this study, to only two striking illustrations : the first, a great swamp in Uganda ; and the second, the shores of Lake Tanganyika. It follows then, that while we must pursue our search for new molluscicides, we must not neglect, at least not at present, all other means of combatting schistosomiasis according to local conditions : drying, drainage, general measures of hygiene and above all the treatment of patients, carriers of schistosomes. © 1956. |
