CAP1 and infection: Cap1 is required for virulence of C. albicans in nematode model. Strains lacking CAP1 induced Dar phenotype less frequently with attenuated virulence compared with the wild-type strain. Worms that could not produce ROS due to a mutation in the host oxidase showed early signs of disease and succumbed to an infection with the cap1Δ/Δ null mutant
