Carbapenem-Resistant Klebsiella pneumoniae Exhibiting Clinically Undetected Colistin Heteroresistance Leads to Treatment Failure in a Murine Model of Infection
Antibiotic resistance is a growing crisis and a grave threat to human health. It is projected that antibiotic-resistant infections will lead to 10 million annual deaths worldwide by the year 2050. Among the most significant threats are carbapenem-resistant Enterobacteriaceae (CRE), including carbapenem-resistant Klebsiella pneumoniae (CRKP), which lead to mortality rates as high as 40 to 50%. F...
متن کاملColistin heteroresistance in carbapenemase-producing Klebsiella pneumoniae.
Sir, Klebsiella pneumoniae is an important pathogen that causes severe and life-threatening infections. Most isolates demonstrate resistance to various antimicrobial agents. Carbapenems have been widely used to treat serious infections with multidrug-resistant K. pneumoniae. However, the increasing use of these compounds has led to the emergence of carbapenem-resistant isolates via acquired gen...
متن کاملGentamicin therapy for sepsis due to carbapenem-resistant and colistin-resistant Klebsiella pneumoniae.
OBJECTIVES Antimicrobial therapy for sepsis caused by carbapenem- and colistin-resistant Klebsiella pneumoniae is not well established. We hypothesized that the early use of gentamicin in cases due to susceptible organisms would decrease the crude mortality rate of this infection. METHODS This retrospective cohort study examined 50 cases of sepsis caused by carbapenem-resistant K. pneumoniae ...
متن کاملLimiting and controlling carbapenem-resistant Klebsiella pneumoniae
Carbapenem-resistant Klebsiella pneumoniae (CRKP) is resistant to almost all antimicrobial agents, is associated with substantial morbidity and mortality, and poses a serious threat to public health. The ongoing worldwide spread of this pathogen emphasizes the need for immediate intervention. This article reviews the global spread and risk factors for CRKP colonization/infection, and provides a...
متن کاملEvaluation and Identification of Carbapenem Resistant Klebsiella pneumoniae Isolated from Hospitalized Patients in Qom City, (Iran)
Background and Objectives: Klebsiella pneumonia is a facultative anaerobe bacterium from enterobacteriaceae family, which causes a wide range of diseases, such as urinary tract infections, cystitis, pneumonia, surgical wounds infections, infectious endocarditis, and diffused infections, especially in patients with HIV infection and immunosuppression. The aim of this study was to identify carbap...
