The Southeast Asian Journal of Tropical Medicine and Public Health. 1977 Jun; 8(2): 190-4http://imsear.searo.who.int/handle/123456789/31707The Southeast Asian Journal of Tropical Medicine and Public Health.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.engAncylostoma --geneticsAnimalsCatsFeces --parasitologyFemaleHybridization, GeneticIntestine, Small --parasitologyMaleParasite Egg CountJournal Article
