Infectivity of Trichinella papuae for experimentally infected red foxes (Vulpes vulpes).

To evaluate infectivity for carnivores as well as other biological characteristics of the newly described Trichinella papuae, eight red foxes were experimentally infected with the parasite. Five weeks after inoculation, T. papuae larvae were recovered from nine different muscle types. The larvae recovered from muscle tissue were shown to be infective to mice, to have a very low tolerance to freezing, and to survive longer than the other Trichinella genotypes in decaying tissue up to 5 weeks after infection.
