The NDM-1 enzyme is one of the class B metallo-beta-lactamase; other types of carbapenemase are class A or class D beta-lactamases. [11] (The class A Klebsiella pneumoniae carbapenemase is currently the most common carbapenemase, which was first detected in North Carolina, United States, in 1996 and has since spread worldwide. [12]
The other type of beta-lactamase is of the metallo type ("type B"). Metallo-beta-lactamases (MBLs) need metal ion(s) (1 or 2 Zn 2+ ions [2]) on their active site for their catalytic activities. [3] The structure of the New Delhi metallo-beta-lactamase 1 is given by 6C89. It resembles a RNase Z, from which it is thought to have evolved.
Between 2007 and 2011, the percentage of Escherichia coli isolates from Canadian hospitals that produce extended spectrum beta lactamases (ESBL) increased from 3.4% to 4.1%; among Klebsiella pneumoniae isolates ESBL producers increased from 1.5% to 4.0%.
Klebsiella causes a range of diseases like pneumonia and infections of the urinary tract, skin and wounds, and is responsible for about a fifth of all deaths attributed to drug-resistant superbugs.
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [3] Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913). Carl Friedlander described Klebsiella bacillus which is why it was termed Friedlander bacillus for many years.
Sulopenem/probenecid is indicated for the treatment of uncomplicated urinary tract infections caused by the designated microorganisms Escherichia coli, Klebsiella pneumoniae, or Proteus mirabilis in adult women who have limited or no alternative oral antibacterial treatment options. [1] [2]
Ceftazidime/avibactam is used for the treatment of: complicated intra-abdominal infections. In these cases it is often used in combination with metronidazole, which provides coverage for anaerobic pathogens. [7] complicated urinary tract infections, including acute pyelonephritis, in adults.
