Rapid Differentiation of Filariae in Unstained and Stained Paraffin-Embedded Sections by a High-Resolution Melting Analysis PCR Assay.

Background: Apart from infection with human filariae, zoonotic filariasis also occurs worldwide, and the numbers of cases have been increasing steadily. Diagnosis of intact filariae in tissues or organs depends on histological identification. The morphology of parasites in tissue-embedded sections is poor and shows high levels of homoplasy.
