Assessment of parasite population dynamics in mixed infections of rodent plasmodia.
Cloned lines of the four rodent Plasmodium species can be differentiated by the RFLP pattern generated following Southern blotting and probing with PCsv4.1, a probe derived from a P. chabaudi chabaudi genomic library. Groups of CBA/Ca mice were inoculated simultaneously with cloned lines from two parasite species or strains. Six mixed species and three mixed strain infections using rodent malaria lines were initiated. The composition of the parasite population in each group was determined qualitatively and semi-quantitatively by analysis of the DNA purified from daily blood samples, thereby providing a dynamic representation of each mixed infection. Effects on the course of parasitaemias are presented and discussed.
