A comparison of the surface and secretions of Trichinella pseudospiralis and T. spiralis.

abstract：:Previous studies of mating interactions between schistosome species from different evolutionary lineages in mice showed that mating is not random: heterospecific pairs form but, given the choice, the preference is for homospecific partners. Mating competition and change of mate were also demonstrated. Schistosoma mans...
