Abstract
We demonstrate that a set of previously described polymerase chain reaction primers used for detection of hemogregarines in reptiles will also amplify the same region of the 18S rRNA gene of reptiles, amphibians, mammals, and insects and thus should not be used for molecular diagnosis. These same primers have also been used to differentiate 2 species of Plasmodium that infect lizards. We provide evidence that the observed variance may have been dependent on parasitemia and not representative of actual molecular differences between the 2 parasite species.
