Abstract:
:Recent studies on antibacterials have focused on the development of antimycobacterial agents and antibacterial peptides, and on furthering the understanding of agents that have been available for several decades, including imidazoles, beta-lactams and quinolones. New areas of research include antisense oligonucleotides, antibacterial peptides and a new class of agents, oxazolidinones.
