title: Use of a DNA probe to analyse the dynamics of infection with rodent malaria parasites confirms that parasite clearance during crisis is predominantly strain- and species-specific.
abstract: A DNA probe, PCsv4.1, isolated from Plasmodium chabaudi chabaudi AS, generates in Southern blotting experiments restriction fragment length polymorphisms specific to a particular rodent malaria parasite line. It was used to develop an assay which allows identification and semi-quantitative compositional analysis of sample parasite populations in which one or more strains, subspecies or species were present. In experiments where mechanisms effecting parasite clearance during crisis were studied, the assay was used to determine the composition of parasite populations present in P. c. chabaudi AS infected mice challenged during crisis with homologous or heterologous parasites. It was thus confirmed that clearance mechanisms during crisis operate in a predominantly specific manner.
