North Carolina State University chemists have created a compound that makes existing antibiotics 16 times more effective against recently discovered antibiotic-resistant "superbugs."
These so-called superbugs are actually bacterial strains that produce an enzyme known as New Delhi metallo-β-lactamase (NDM-1). Bacteria that produce this enzyme are practically impervious to antibiotics because NDM-1renders certain antibiotics unable to bind with their bacterial targets. Since NDM-1 is found in Gram-negative bacteria like K. pneumoniae, which causes pneumonia, urinary tract, and other common hospital-acquired infections, it is of particular concern.
