Reptile and bird hosts of malaria parasites (Plasmodium) have nucleated erythrocytes. Infected blood thus contains a mix of abundant host and scant parasite DNA which has prevented identification of Plasmodium microsatellites. We developed a protocol for isolation of microsatellite markers for Plasmodium mexicanum, a parasite of lizards. The ATT repeat was common in the genome of P. mexicanum, but most (87%) of these repeats were exceptionally long (50-206 + repeats). Seven microsatellite markers with polymerase chain reaction primers are described. The protocol should allow discovery of microsatellites of malaria parasites (with AT-rich genomes) infecting bird and reptile hosts.
