Carbapenem-resistant Pseudomonas aeruginosa: association with virulence genes and biofilm formation

Braz. j. microbiol; 48 (2), 2017
Abstract Pseudomonas aeruginosa is an opportunistic pathogen that causes frequently nosocomial infections, currently becoming more difficult to treat due to the various resistance mechanisms and different virulence factors. The purpose of this study was to determine the risk factors independently associa...

Draft genome sequence of a multidrug-resistant beta-lactamase OXA-357-producing Acinetobacter pittii ST865 clinical isolate from China

Braz. j. microbiol; 48 (2), 2017
Abstract Worldwide increasing emergence of carbapenem-resistant Acinetobacter spp. has rendered the limited availability of effective antimicrobial agents and has become a major public health concern. In this study, we report the draft genome sequence of A. pittii TCM156, a multidrug-resistant isolate th...

Draft genome sequence of a GES-5-producing Serratia marcescens isolated in southern Brazil

Braz. j. microbiol; 48 (2), 2017
Abstract Serratia marcescens is a Gram-negative rod intrinsically resistant to polymyxins and usually associated with wound, respiratory and urinary tract infections. The whole genome of the first GES-5-producing S. marcescens isolated from a Brazilian patient was sequenced using Ion Torrent PGM System. ...

Modified Carba NP test for the detection of carbapenemase production in gram-negative rods: optimized handling of multiple samples

Braz. j. microbiol; 48 (2), 2017
Abstract The modified Carba NP test presented here may be a valuable tool for laboratories interested in investigating a large number of carbapenemase-producing bacteria in a less-costly way. The test was evaluated against 48 carbapenemase-producing and carbapenemase-non-producing gram-negative bacteria....

Urinary tract infection caused by community-acquired extended-spectrum β-lactamase-producing bacteria in infants

J. pediatr. (Rio J.); 93 (3), 2017
Abstract Objective: Urinary tract infection (UTI) caused by resistant strains of bacteria is increasingly prevalent in children. The aim of this study was to investigate the clinical characteristics and risk factors for UTI caused by community-acquired extended-spectrum β-lactamase (CA-ESBL)-produc...

Distribution of the bla OXA, bla VEB-1, and bla GES-1 genes and resistance patterns of ESBL-producing Pseudomonas aeruginosa isolated from hospitals in Tehran and Qazvin, Iran

Abstract INTRODUCTION: Pseudomonas aeruginosa is one of the most common nosocomial pathogens. The emergence of extended spectrum β-lactamases (ESBLs) has been increasingly reported as a major clinical concern worldwide. The main aim of the present study was to determine the distribution of bla OXA,...

Molecular detection of β-lactamase and integron genes in clinical strains of Klebsiella pneumoniae by multiplex polymerase chain reaction

Abstract INTRODUCTION: Infections caused by β-lactamase-producing gram-negative bacteria, such as Klebsiella pneumoniae, are increasing globally with high morbidity and mortality. The aim of the current study was to determine antimicrobial susceptibility patterns and the prevalence of antibiotic r...

Escherichia Coli productora de Nueva Delhi metalo-β-lactamasa en Colombia: reporte de caso

Infectio; 21 (2), 2017
Notificamos un caso de infección por Escherichia coli productora de Nueva Delhi metalo-b-lactamasa (NDM) en un paciente que desarrolló un absceso subcapsular hepático como complicación de una colecistectomía laparoscópica. La NDM es una carbapenemasa adquirida tipo Ambler B, que confiere resistenci...

Colonización por Klebsiella pneumoniae productora de carbapenemasa tipo KPC en un hospital universitario
KPC-producing Klebsiella pneumoniae colonization at a University Hospital

Medicina (B.Aires); 77 (2), 2017
Se realizó un estudio de vigilancia en un Hospital Universitario de la Ciudad Autónoma de Buenos Aires con el fin de determinar la prevalencia de colonización por cepas de Klebsiella pneumoniae productora de carbapenemasa, bacterias de gran importancia epidemiológica. A tal fin, se investigó su pres...
