Molecular Characterization of a Reemergent Parasite in Sri Lanka, Suggestive of a Novel Strain.

Sri Lanka achieved elimination status for lymphatic filariasis in 2016; still, the disease remains a potential public health issue. The present study is aimed at identifying a subperiodic parasite which has reemerged in Sri Lanka after four decades via molecular-based analysis. Polymerase chain reaction performed with pan-filarial primers specific for the internal transcribed spacer region-2 (ITS-2) of the rDNA of filarial parasites isolated from human, canine, and feline blood samples yielded a 615 bp band establishing the species identity as .
