Developmental characteristics and infectivity of P. berghei-P. vivax parasites in A. stephensi mosquitoes^a

Parasite	% of midgut infected	No. of oocysts/midgut	% of salivary gland infected	No. of sporozoites/salivary gland (103)	% of mice infected after mosquito bitesb
P. berghei-P. vivax	80.72	54.76	75	8.5	100
P. berghei ANKA	75.14	42.25	66	10	100

^aMean of 3 experiments, with at least 20 mosquitoes examined in each experiment.

^bThree infected mosquitoes were allowed to feed on C57BL/6 mice for 3 min. Blood-stage parasitemia was assessed 5 days later.
