GNPDA1 and disseminated candidiasis: To assess whether Gnp1/2/3-mediated amino acid uptake is required for full fungal virulence in vivo, we tested the gnp1Δ, gnp2Δ, and gnp3Δ strains; the corresponding revertant strains; and the gnp1Δ/gnp2Δ/gnp3Δ strain in a murine model of disseminated candidiasis.
