Although there is currently a shortage of new drugs in the antimicrobial realm, there are a few antibiotics currently being studied and tested for the treatment of serious Gram-negative bacterial infections. These include cephalosporins, ceftobiprole, ceftarolin and FR-264205. The lack of newly

emerging antimicobrial drugs have resulted in the revisit of old antibiotic drugs such as colistin (Polymyxins) and fosfomycin, which are traditionally considered to be toxic but have gained a principal role in the treatment of the most problematic MDR Gram-negative pathogens including

development of adaptive resistance mechanisms by bacteria; a lack of responsible antimicrobial stewardship such that the use of multiple broad-spectrum agents has helped perpetuate the cycle of increasing resistance; and a lack of good infection control practices.

isolates. Subsequently, carbapenems are sometimes not active against those serious infections. That is why clinicians around the world have reconsidered the use of older antimicrobial agents, including
