The immunosuppressants tacrolimus (FK506) and cyclosporine A inhibit calcineurin and have potent antifungal activity. In this study, 24% of Cryptococcus neoformans isolates from solid-organ transplant patients exhibited altered sensitivity to these drugs, which may have an impact on the infectious course but does not appear to be the consequence of immunosuppressive therapy.
