Survival of heterotopic neonatal heart transplants in T. cruzi-infected mice

	Recipient strain	Parasite strain	D.P.I.	Failures/ total
Exp. 1	C3H(He)SnJ	Sylvio X10/4	180–380	2/18
	C3H(He)SnJ	None		1/8
Exp. 2	C3H(He)SnJ	Sylvio X10/4	210–230	2/13
	C3H(He)SnJ	None		1/14

Syngeneic neonatal hearts were transplanted into age-matched C3H(He)SnJ male mice that were either not infected or were infected 180–380 days previously (D.P.I.) with the Sylvio X10/4 clone of T. cruzi. The number of hearts that failed to beat within 14 days posttransplantation from the total transplanted is indicated.
