OBJECTIVES Incompatibility group N (IncN) plasmids have been associated with the dissemination of antimicrobial resistance and are a major vehicle for the spread of bla(VIM-1) in humans and bla(CTX-M-1) in animals. A plasmid multilocus sequence typing (pMLST) scheme was developed for rapid categorization of IncN plasmids. METHODS Twelve fully sequenced IncN plasmids available at GenBank were ...
SummaryBackground Wastewater-based monitoring represents a useful tool for antibiotic resistance surveillance. Aim To investigate the prevalence and abundance of genes (ARGs) in hospital wastewater over time. Methods Wastewater from two hospitals Finland (HUS1 HUS2) was monitored weekly nine weeks (weeks 25–33) summer 2020. A high-throughput real-time polymer...
Beta-lactamase producing strains of Pseudomonas aeruginosa are important etiological agents of hospital infections. Carbapenems are among the most effective antibiotics used against Pseudomonas infections, but they can be rendered infective by group B β -lactamase, commonly called metallo-beta lactamase. In this study, the antimicrobial sensitivity patterns of P. aeruginosa strains isolated fro...
OBJECTIVES We describe 12 VIM-1-producing strains (7 Enterobacter cloacae, 2 Klebsiella pneumoniae and 3 clonal Klebsiella oxytoca strains) detected among clinically relevant Enterobacteriaceae isolates from routine cultures at the Hospital del Mar (Barcelona, Spain) from December 2006 to May 2007. METHODS Susceptibility to carbapenems was evaluated with the MicroScan system. beta-Lactamases ...
Carbapenem susceptibility in Enterobacteriaceae (M9921, M9959) revealed the presence of MBLs bla(VIM-2) (M9959) and bla(IMP-8) (M9921), both as first cassettes of class-1-integrons. ESBL bla(PER-2) was detected in both strains and M9921 also harboured qnrB10, aac(6')-Ib and aac(6')-Ib-cr. This is the first report of MBLs in Enterobacteriaceae from Argentina.
Objective(s): Resistance to carbapenems as the last line for controlling resistant bacteria is increasing due to production of carbapenemase. The aim of this study was to detect the plasmid-encoded carbapenemases using phenotypic methods and multiplex PCR among the multi-drug resistant (MDR) isolates from patients with urinary tract infection (UTI) in northern Iran.<br...
A plasmid-encoded class II transposon element was identified in a carbapenem-resistant Pseudomonas putida isolate. Tn1332, closely related to Tn1331, harbored the metallo-beta-lactamase gene bla(VIM-2) in addition to four other antibiotic resistance genes, aacA4, aadA1, bla(OXA-9), and bla(TEM-1), and two novel insertion sequences, ISPpu17 and ISPpu18.
We report the first description of the metallo-β-lactamase VIM-31, a new variant of VIM-2 with Tyr224His and His252Arg mutations, in Enterobacter cloacae 11236, which was isolated from blood specimens of a patient with colonic adenocarcinoma in Belgium. bla(VIM-31) was found on a class 1 integron located on a self-transferable but not typeable 42-kb plasmid. Compared to values published elsewhe...
introduction: pseudomonas aeruginosa is one of the leading causes of nosocomial infections, and antibiotic resistance of this pathogen is an important concern in treating such infections. the current work was conducted to investigate the prevalence of bla-imp, and bla-vim metallo-beta-lactamase (mbl) among clinical and environmental p. aeruginosa isolates obtained from icus of different hospita...
Pseudomonas aeruginosa COL-1 was identified in a blood culture of a 39-year-old-woman treated with imipenem in Marseilles, France, in 1996. This strain was resistant to beta-lactams, including ureidopenicillins, ticarcillin-clavulanic acid, cefepime, ceftazidime, imipenem, and meropenem, but remained susceptible to the monobactam aztreonam. The carbapenem-hydrolyzing beta-lactamase gene of P. a...
