This report describes a method for the identification of the sex of Schistosoma mansoni cercariae using a cloned DNA probe which is female-specific. The probe is a 339 bp repeat; the sequence is presented. Cercariae from nine mono-miracidially infected snails were used in a double blind study. Mice were infected and the sex of adult worms observed. DNA was isolated from cercariae, digested with EcoRI, subjected to agarose gel electrophoresis, transferred to a matrix and hybridized with the cloned female-specific DNA probe. In all nine cases the sex of the cercariae as determined by DNA analysis agreed with the sex of the adult parasites.
