In vitro culture of Plasmodium berghei-ANKA maintains infectivity of mouse erythrocytes inducing cerebral malaria
Malaria Journal, 2011•Springer
Abstract 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.

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 …

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.
