Re-Discovery of : Genomic and Functional Analysis of Viruses from Isolates.

Giardiasis, caused by the protozoan parasite , is an intestinal diarrheal disease affecting almost one billion people worldwide. A small endosymbiotic dsRNA viruses, virus (GLV), genus , family , might inhabit human and animal isolates of . Three GLV genomes have been sequenced so far, and only one was intensively studied; moreover, a positive correlation between GLV and parasite virulence is yet to be proved.
