\". Robust exoerythrocytic schizogony with extensive cell growth and DNA replication was observed for P. falciparum mei2- liver stages in human liver-chimeric mice. However, P. falciparum mei2- liver stages failed to complete development and did not form infectious exoerythrocytic merozoites, thereby preventing their transition to asexual blood stage infection. Therefore, P. falciparum mei2- is a replication-competent, attenuated human malaria parasite strain with potentially increased potency, useful for vaccination to protect against P. falciparum malaria infection.\"

Normal infectivity of sporozoites to hepatocytes in vitro and in vivo. Mutant parasites develop into large, mature liver stages with extensive nuclear division and expression of merozoite specific proteins, such as msp1 and ama1. Most of the parasites arrest growth, however, just before the formation of infective merozoites. Only after intravenously infection of mice with high doses of sporozoites (2x10(5)) some of the mice (3 out of 10) developed blood infections with a greatly prolonged prepatent period (12-14 days).
