title: Experimental cross-breeding of Ancylostoma tubaeforme (Zeder, 1800) and Ancylostoma caninum (Ercolani, 1859).
abstract: In experimental crosses between A. tubaeform and A caninum the worms failed to produce progeny in dual-strain combinations. Even though these two strains did not fail to copulate. Egg production was observed only in identical single-strain combinations. This supports the assumption that the two species are genetically separate and valid.
