Abstract
The 18S rDNA genes of 10 Eimeria species from rodents (E. albigulae, E. arizonensis, E. falciformis, E. langebarteli, E. nieschulzi, E. onychomysis, E. papillata, E. reedi, E. separata, E. sevilletensis) were polymerase-chain-reaction (PCR)-amplified, digested with 12 restriction endonucleases, and electophoresed in agarose gels. The resulting fragment patterns (riboprints) distinguished all species except E. sevilletensis from E. falciformis, and E. arizonensis from E. albigulae; the sporulated oocysts of the latter two species and of E. onychomysis are often indistinguishable morphologically. When the restriction fragment data were analyzed using distance and parsimony phylogenetic methods a clade was found consistently, which contained E. arizonensis, E. albigulae, E. onychomysis, E. reedi, and E. papillata. This finding and other results of the phylogenetic analyses agreed and supplemented previous phylogenetic work on the Eimeria of rodents. Riboprinting appears to provide useful data for taxonomic and phylogenetic studies on the genus Eimeria and may be especially practical when samples do not contain enough oocysts for other molecular-based methods.
