By using plasmids containing the CRISPR/Cas9 components adapted to the closely related parasite Toxoplasma gondii, we successfully knocked out a green fluorescent protein (GFP) in an Nc-1 GFP-expressing strain, and efficiently disrupted the NcGRA7 gene in the Nc-Spain7 isolate by insertion of a pyrimethamine resistance cassette. The successful use of this technology in N. caninum lays the foundation for an efficient, targeted gene modification tool in this parasite. %~
