The asexual cycle in the definitive host the cat

Bradyzoites released from the enteroepithelial cycle penetrate the lamina propria below the epithelial cell in the intestine of the cat and multiply as tachyzoites. The tachyzoites are disseminated throughout the body within a few days, eventually encysting in tissues. The extraintestinal cycle in the cat differs from the similar cycle in non-feline intermediate host in two aspects: (1) tachyzoites have not been demonstrated in feline intestinal epithelial cells, whereas they do occur in non-feline intermediate hosts (Dubey and Frenkel 1973) and (2) the enteroepithelial types of T. gondii are non-infectious to mice by any route (Dubey and Frenkel 1976), which suggests that the feline enteroepithelial forms do not give rise to tachyzoites.
