What is KPC beta lactamase?
Carbapenemases are β-lactamases with versatile hydrolytic capacities. They have the ability to hydrolyze penicillins, cephalosporins, monobactams, and carbapenems. Of these, the KPC carbapenemases are the most prevalent, found mostly on plasmids in Klebsiella pneumoniae.
What is KPC producing bacteria?
Klebsiella pneumoniae carbapenemase (KPC)-producing bacteria are a group of emerging highly drug-resistant Gram-negative bacilli causing infections associated with significant morbidity and mortality.
How does KPC work?
Polymyxins achieve concentration-dependent bactericidal killing and are often the only agents active against KPC-producing bacteria that achieve adequate levels in the serum to treat serious bloodstream infections.
Is Klebsiella resistant to beta lactam antibiotics?
Klebsiella pneumoniae is an Enterobacteriaceae member which often displays resistance towards β-lactam antibiotics, particularly through β-lactamase expression of which the most important are cephalosporinases, such as extended-spectrum β-lactamases (ESBLs) and carbapenemases [6].
Do all gram negative bacteria produce beta-lactamase?
Beta-lactam antibiotics are typically used to treat a broad spectrum of Gram-positive and Gram-negative bacteria. Beta-lactamases produced by Gram-negative organisms are usually secreted, especially when antibiotics are present in the environment….Beta-lactamase.

Is KPC a beta-lactamase?
Recently, Klebsiella pneumoniae carbapenemase (KPC), a class A beta-lactamase, has emerged and is spreading worldwide, challenging the therapeutic management of infected patients. KPC enzymes confer resistance to penicillins, cephalosporins, carbapenems, and most beta-lactamase inhibitors.
Is KPC a CRE?
The term CRE refers to carbapenem-resistant and carbapenemase-producing Enterobacteriaceae. Currently, the most common type of carbapenemase in the United States is the Klebsiella pneumoniae carbapenemase (KPC).
What KPC means?
Knowledge, Practices and Coverages. KPC. Kokomo Police Cadets. KPC. Key Purchasing Criteria.
How do you get KPC?
In healthcare settings, Klebsiella bacteria can be spread through person-to-person contact (for example, from patient to patient via the contaminated hands of healthcare personnel, or other persons) or, less commonly, by contamination of the environment. The bacteria are not spread through the air.
Is Klebsiella pneumoniae resistance to penicillin?
Klebsiella pneumoniae (K. pneumoniae) is a common cause of health-care associated infections (HAIs) and has high levels of antibiotic resistance.
What antibiotic treats Klebsiella pneumoniae?
K pneumoniae UTI Complicated cases may be treated with oral quinolones or with intravenous aminoglycosides, imipenem, aztreonam, third-generation cephalosporins, or piperacillin/tazobactam. Duration of treatment is usually 14-21 days.
How does KPC-2 contribute to antibiotic resistance?
One key mechanism of resistance is the breakdown of β-lactam antibiotics by β-lactamase enzymes. KPC-2 is a β-lactamase that inactivates carbapenems and β-lactamase inhibitors (e.g., clavulanate) and is prevalent around the world, including in the United States.
What kind of bacteria is Klebsiella pneumoniae ( kpc )?
Klebsiella pneumoniae carbapenemase (KPC)-producing bacteria are emerging, highly drug-resistant pathogens whose incidence is rapidly increasing in a variety of clinical settings.
Is there any treatment for KPC-producing bacteria?
With the spread of KPC-producing bacteria, clinicians are becoming increasingly dependent on polymyxins and tigecycline for treatment of these infections. Some experts suggest that high-dose continuous infusion of a carbapenem may be helpful, though clear evidence of efficacy is lacking.
What kind of transposon is the KPC gene?
KPCs are encoded by the gene bla KPC, whose potential for inter-species and geographic dissemination is largely explained by its location within a Tn3-type transposon, Tn4401. This transposon is a genetic element which is capable of inserting into diverse plasmids of Gram-negative bacteria.
