Extract

1. In intact rats infected with P. berghei spontaneous eradication of infection has occurred by about 4 months after the day of inoculation.

2. These recovered rats show a strong residual immunity to reinfection with a heterologous strain, but this has begun to wane by 15–18 months after cure of the initial infection.

I owe many thanks to Miss W. J. Wall and Miss J. Wrugh of the Ross Institute for maintenance of the rats and assistance with the blood films.
