SYNOPSIS. Babesia bigemina was identified in the erythrocytes of calves as early as 9 days 21 hours after infected larval ticks (Boophilus microplus) had been placed on them. This confirms the circumstantial data [Hoyte, (1961): J. Protozool. 8, 462–61, which indicated that there is no pre-erythrocytic schizogony in the life cycle of B. bigemina.The earliest time at which parasites were themselves found to be capable of infecting ticks was between 11 and 12 days, (i.e., about two days after parasites were first seen in the blood). It is suggested that this delay occurs because, until this time, parasites are present in the blood in such small numbers that none survive digestion within the tick.
