Role of the dog, fox, cat and human as carnivore vectors in the transmission of the Sarcosporidia that affect sheep meat production [protozoa]

Faecal samples were examined for sporocysts for 60 days after experimental carnivores had been fed sarcocysts in, or removed from, sheep meat. Neither macroscopic nor microscopic sarcocysts from sheep carcasses were transmissible by humans or ferrets. Microscopic sarcocysts were readily infective to domestic dogs, dingoes and foxes but not to cats; large numbers of sporocysts were excreted. Both fat and thin visible sarcocysts were transmitted to cats; the resultant levels of sporocysts, although low, were adequate to perpetuate the life cycle. The consequent importance of foxes and feral cats, in addition to dogs, is therefore noted.
