Fusaric acid (FA) is a virulence factor in mice. (A) Groups of 10 immunosuppressed Oncins France 1 male mice were inoculated with 10⁷ microconidia of the indicated strains by lateral tail vein injection. Percentage survival was plotted for 20 days. Data shown are from one representative experiment. Experiments were performed three times with similar results. (B) Four randomly chosen surviving mice inoculated with 10⁷ microconidia of the indicated strains were sacrificed at 5 days post‐inoculation (dpi) and homogenates obtained from the indicated organs were quantitatively cultured on potato dextrose agar (PDA). wt, wild‐type strain. *P < 0.05; **P < 0.001; ns, not significant.
