Comparison of egress rates from donor and host cells.^*

Exp.	No. donor mice	No. host mice	Donor egress rate	Host egress rate
1	2	5	14 ± 2	12 ± 2
2	3	4	17 ± 4	18 ± 3
3	3	7	20 ± 4	8 ± 1

^*Donor and host egress rates (percentage of parasites egressing per hour) are calculated similarly (see Methods), except that the host egress rate is multiplied by the (host cells)/(donor cells) ratio to correct for undetected reinvasion events occurring in host cells. Exp., experiment. No., number.
