title: Genotyping Taenia tapeworms by single-strand conformation polymorphism of mitochondrial DNA.
abstract: To overcome limitations in identifying tapeworms of the genus Taenia by traditional approaches, we have established a single-strand conformation polymorphism (SSCP) method utilizing two different regions of mitochondrial (mt) DNA as targets. The NADH dehydrogenase 1 and the cytochrome c oxidase subunit I genes were amplified from genomic DNA by polymerase chain reaction (PCR), denatured and subjected to electrophoresis in mutation detection enhancement gels. SSCP analysis achieved delineation among eight different species of Taenia from different hosts based on characteristic profiles and enabled the detection of intraspecific variability in profiles for some taxa. This SSCP-based typing method has important implications for taxonomy, diagnosis and for studying the genetic structure of Taenia populations.
