Extract

The varying susceptibility of local races of bulinid snails to different strains of Schistosoma haematobium has been recorded by many workers including Le Roux, 1954; Cridland, 1955, 1957; McCullough, 1957, 1962; Wright, 1962, 1963; Cowper, 1963; Pitchford, 1965 and Paperna, 1968. The respective species groups of snails referred to are those created by Mandahl-Barth (1958). As a result of his experiments Le Roux (1958) suggested that there are two separate species of parasite, the form transmitted in North Africa by the truncates group of snails being known as S. haematobium and that developing in Africa south of the Sahara in the africanus species group as S. capense (Harley, 1864), a view which has been supported by many workers.
