Candida albicans is the most common human opportunistic pathogen, and also one of the main sources of infection in hospital-acquired fungal disease. The ability of iron acquisition is important for colonization, survival and the establishment of infections in the hostile environment, which is considered as a prerequisite for C. albicans morphogenesis and pathogenesis. The multicopper oxidase (MCO) genes are key components of high-affinity iron uptake (HAIU) systems in C. albicans. A genome survey reveals th...
