Adaptation-based resistance to siderophore-conjugated antibacterial agents by Pseudomonas aeruginosa.

abstract：:Therapeutic treatment for systemic mycoses is severely hampered by the extremely limited number of antifungals. The difficulty of treatment of fungal infections in the central nervous system is further compounded by the poor central nervous system (CNS) penetration of most antifungals due to the blood-brain barrier. O...
