BACKGROUND: Infection with Plasmodium berghei is a widely used model of murine malaria and a powerful tool for reverse genetic and pathogenesis studies. However, the efficacy of in vitro reinvasion of erythrocytes is generally low, limiting in vitro studies. METHODS: Plasmodium berghei ANKA-infected blood obtained from a susceptible infected mouse was cultured in various conditions and in vitro parasitaemia was measured every day to evaluate the rate of reinvasion. RESULTS: High quality culture media were used and reinvasion rates were improved by vigorous orbital shaking of the flask and increasing density of the medium with gelatin. DISCUSSION: Using these settings, reinvasion of normal mouse erythrocytes by the parasite was obtained in vitro over two weeks with preservation of the infectivity in vivo.
