IRP scientists describe potential antibody approach for treating multidrug-resistant Klebsiella pneumoniae
Promising concept may lead to an alternative to antibiotics
Researchers are developing a promising alternative to antibiotic treatment for infections caused by Klebsiella pneumoniae bacteria resistant to carbapenem antibiotics. The approach uses antibodies to target the K. pneumoniae protective capsule polysaccharide, allowing immune system cells called neutrophils to attack and kill the bacteria. The early stage, in vitro research was conducted by scientists at the National Institute of Allergy and Infectious Diseases’ (NIAID) Rocky Mountain Laboratories and the New Jersey Medical School-Rutgers University.
Klebsiella bacteria cause about 10 percent of all hospital-acquired infections in the United States. A carbapenem-resistant K. pneumoniae strain known as multilocus sequence type 258 (ST258) is one of the antibiotic-resistant organisms labeled an urgent threat by the Centers for Disease Control and Prevention. ST258 is particularly concerning because it is resistant to most antibiotics. It is a significant cause of mortality among people with bloodstream infections.
