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. © 2011 Jambou et al; licensee BioMed Central Ltd.
