Genetic hybrids of Plasmodium falciparum identified by amplification of genomic DNA from single oocysts

Mol Biochem Parasitol. 1991 Dec;49(2):239-43. doi: 10.1016/0166-6851(91)90067-g.

Abstract

Individual oocysts from Plasmodium falciparum-infected Anopheles gambiae and Anopheles stephensi mosquitoes have been examined by the PCR technique, after their removal from the midgut. The DNA obtained from these oocysts has been amplified using oligonucleotide primers specific for part of the merozoite surface antigen MSA-1 gene. This technique distinguishes oocysts which are the products of self-fertilisation events from those which are the products of cross-fertilisation between different parasite clones.
