title: Brain capillary blockage produced by a virulent strain of rodent malaria.
abstract: A sudden enhancement in virulence of a mild Plasmodium berghei yoelii 17 x strain resulted in fulminating and fatal infections in CF1 and A/J mice. The virulent strain has maintained its characteristics after ten cyclical transmissions through Anopheles stephensi. The visible expression of virulence of the mutated strain is its ability to cross the blood-brain barrier and cause intravascular sequestration of injected erythrocytes and blockage of brain capillaries. We, therfore, believe that the virulent line of Plasmodium berghei yoelii 17 x could serve as a useful laboratory model for the study of "cerebral malaria."
