BACKGROUND AND OBJECTIVE The production of carbapenemases especially Klebsiella pneumoniae carbapenemase (KPC) is the most important mechanism of enzymatic resistance in isolated Enterobacteriaceae such as K. pneumoniae . The purpose of this study was detected of the carbapenemase producer K. pneumoniae strains with phenotypic and genotypic methods. METHOD Out of 800 strains, 270 K. pneumonia...
OBJECTIVES Production of carbapenemase, especially Klebsiella pneumoniae carbapenemases (KPC), is one of the antibiotic resistance mechanisms of Enterobacteriaceae such as Klebsiella oxytoca. This study aimed to investigate and identify KPC-producing K. oxytoca isolates using molecular and phenotypic methods. METHODS A total of 75 isolates of K. oxytoca were isolated from various clinical sam...
Background: Multidrug-resistant Acinetobacter baumannii is associated with life threatening nosocomial infections and hospital outbreaks. The organism is resistant to most commonly used antibiotics including carbapenems. Aim and Objectives: To study carbapenemase production among multidrug-resistant clinical isolates of A. baumannii. Material and Methods: Fifty multidrug-resistant A. baumannii ...
In the United States, the production of the Klebsiella pneumoniae carbapenemase (KPC) is an important mechanism of carbapenem resistance in Gram-negative pathogens. Infections with KPC-producing organisms are associated with increased morbidity and mortality; therefore, the rapid detection of KPC-producing pathogens is critical in patient care and infection control. We developed a real-time PCR...
Background Carbapenemase-producing Enterobacteriaceae (CPE), including KPC-producing Klebsiella pneumoniae (KPC-Kpn), are an increasing threat to patient safety. Objectives To use WGS to investigate the extent and complexity of carbapenemase gene dissemination in a controlled KPC outbreak. Materials and methods Enterobacteriaceae with reduced ertapenem susceptibility recovered from rectal s...
OBJECTIVES This study examined Klebsiella pneumoniae clinical isolates and their bla(KPC) plasmids to determine potential relatedness of the isolates and their plasmids harbouring carbapenem resistance mechanisms. METHODS K. pneumoniae carbapenemase (KPC)-producing K. pneumoniae from New York City (NYC) (n = 19) and Toronto (n = 2) were typed by PFGE and multilocus sequence typing (MLST). bla...
Fourteen out of 16 carbapenem-resistant quinolone-susceptible Enterobacter cloacae isolates were found to carry qnrB2 and bla(KPC-2) genes encoded on the same plasmid. One isolate also carried the aac(6')-Ib-cr gene. Coexistence of quinolone resistance determinants and bla(KPC-2) on the same plasmid in quinolone-susceptible E. cloacae isolates may have important clinical implications.
Increased incidence of infections due to Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KPC-Kp) was noted among patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) at a single hospital. An epidemiologic investigation identified KPC-Kp and non-KPC-producing, extended-spectrum β-lactamase (ESBL)-producing Kp in cultures from 2 endoscopes. Genotypi...
We describe the first outbreak of Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-KP), the infection control measures adopted and the shift in resistance patterns of isolates during antibiotic treatment. The ST258 KPC-KP strain exhibited a multiresistant antibiotic phenotype including co-resistance to gentamycin, colistin and tigecycline intermediate susceptibility. Isolates be...
We performed whole genome sequencing on a clinical multidrug-resistant Klebsiella pneumoniae strain 223/14. Investigation into its draft genome revealed the presence of KPC-6 variant, suggesting carbapenemase is present in this isolate. We found a plasmid-borne KPC gene (882 bp) inserted between two transposase genes in the genome of K. pneumoniae 223/14.
