Abstract
Sporozoites of Leucocytozoon simondi were found in impression smears from the livers of ducks which had received sporozoites up to 114 hours previously. Sporozoites of L. dubreuili were found in impression smears of the livers of robins which had received sporozoites up to 11 days previously and in the heart of one 84 hours after it had received sporozoites. Successful transmission of these parasites by subinoculations of blood from birds which received sporozoites are reported. The persistence of sporozoites for several days in blood would explain the transmission of parasites by subinoculations of blood before completion of an asexual cycle.
