[Experimental study of a Malagasy strain of Schistosoma haematobium: compatibility with different Bulinus snails, potential intermediate hosts].

Experimental investigation on a malagasy strain of S. haematobium: compatibility with different Bulinus snails, potential intermediate hosts. A comparative experimental study of the infectivity of different Bulinus snails by a reference S. haematobium strain was made under laboratory conditions. The results support the role of Bulinus obtusispira as an intermediate host in Madagascar but some other Bulinus species could exist and play a role in the fields far away from the experimental criteria here described.
