Irrational antibiotic usage has led to vast spread resistance to available
antibiotics, but we refuse to slide back to "preantibiotic era." The threat is
serious with the "Enterococcus, Staphylococcous, Klebsiella, Acinetobacter,
Pseudomonas and Enterobacter" organisms causing nosocomial infections that are
difficult to treat because of the production of extended spectrum ?-lactamases,
carbapenamases and metallo-?-lactamases. Facing us is a situation where soon
multidrug resistance would have spread across the globe with no antibiotics to
withstand it. The infectious disease society of America and Food and Drug
Administration have taken initiatives like the 10 × '20 where they plan to
develop 10 new antibiotics by the year 2020. Existing classes of antibiotics
against resistant bacteria include the carbapenems, oxazolidinones,
glycopeptides, monobactams, streptogramins and daptomycin. Newer drugs in
existing classes of antibiotics such as cephalosporins, aminoglycosides,
tetracyclines, glycopeptides and ?-lactamase inhibitors continue to get
synthesized. The situation demands newer targets against bacterial machinery.
Some of them include the peptidoglycantransferase, outer membrane protein of
Pseudomonas, tRNA synthase, fatty acid synthase and mycobacterial ATP synthase.
To curb the irrational and excessive usage of presently available antibiotics
should be a priority if they are still to be kept in usage for the future.
