INTRODUCTION: Infections due to multidrug-resistant (MDR) pathogens are a medical challenge. There is considerable apprehension among clinicians regarding pathogens reported as carrying New Delhi metallo-β-lactamase-1 (NDM) and Klebsiella pneumoniae carbapenemase (KPC) genes from their patients. In the face of extremely high rates of antimicrobial resistance, it is essential to gauge the clinical significance of isolation of pathogens carrying these genes from clinical samples. This study compares the outcome of patients infected with pathogens carrying NDM/KPC genes versus those without these genes...

BACKGROUND: Gram-negative bacilli are a cause of serious infections in the pediatric population. Carbapenem are the treatment of choice for infections caused by multidrug-resistant Gram-negative bacilli, but the emergence of carbapenem resistance has substantially reduced access to effective antimicrobial regimens. Children are a population vulnerable to bacterial infections and the emergence of resistance can worsen prognosis. The aim of this study is to describe the clinical and molecular characteristics of infections caused by carbapenem-resistant Gram-negative bacilli in pediatric patients from five tertiary-care hospitals in Medellín, Colombia...

Carbapenems are considered the last-resort antibiotics to treat infections caused by multidrug-resistant Gram-negative bacilli. The Klebsiella pneumoniae carbapenemase (KPC) enzyme hydrolyses β-lactam antibiotics including the carbapenems. KPC has been detected worldwide in Enterobacteriaceae and Pseudomonas aeruginosa isolates associated with transposon Tn4401 commonly located in plasmids. Acinetobacter baumannii has become an important multidrug-resistant nosocomial pathogen. KPC-producing A. baumannii has been reported to date only in Puerto Rico...

The increasing use of carbapenems for treating multidrug-resistant (MDR) Gram-negative bacterial infections has contributed to the global dissemination of carbapenem-resistant Enterobacteriaceae (CRE). Serine and metallo-β-lactamases (MBLs) that hydrolyze carbapenems have become prevalent and endemic in some countries, necessitating the use of older classes of agents, such as colistin. A total of 19,719 isolates of Enterobacteriaceae (excluding Proteeae and Serratia spp., which have innate resistance to colistin) were collected from infected patients during 2012 and 2013 in a global surveillance program and tested for antimicrobial susceptibility using CLSI methods...
