methods of infesting sheep with gastro-intestinal nematodes after cryopreservation: dosing of larvae in gelatin capsules compared to dosing of larvae in water suspension.cryopreservation of the infective larvae (l3) of nematodes is being used increasingly for the routine maintenance of pure strains of nematodes in the laboratory. gelatin capsules are frequently used to administer the l3 of nematodes to sheep, but with some nematode species this method usually does not give good results with cryopreserved larvae. the development in sheep of cryopreserved l3 of trichostrongylus spp. and other ovine nematodes was compared when the larvae were administered either in ...19846533514
