Evaluation of the Sensitivities of DNA Extraction and PCR Methods for Detection of Giardia duodenalis in Stool Specimens

摘要

Sensitivities of DNA extraction methods and PCR methods for Giardia duodenalis were evaluated. A combination of the most sensitive methods, i.e., FTA filter paper and a PCR protocol using RH11/RH4 and GiarF/GiarR primers, showed no significant differences compared to immunofluorescence assay in terms of their sensitivities and specificities.
