Klebsiella pneumoniae productora de carbapenemasas tipo KPC es uno de los principales agentes causante de infecciones nosocomiales a nivel mundial. En Venezuela se han identificado aislados de esta bacteria, sin embargo, se conoce poco sobre su dispersión. El objetivo de este estudio fue realizar la epi...
Abstract Staphylococcus aureus and Staphylococcus saprophyticus are the most common and most important staphylococcal species associated with urinary tract infections. The objective of the present study was to compare and to evaluate the accuracy of four phenotypic methods for the detection of beta-lacta...

Abstract INTRODUCTION: We compared the prevalence and antimicrobial susceptibility of non-fermenting gram-negative bacilli (NFGNB) isolated from clinical samples at a Brazilian tertiary care hospital in 2008 and 2013. METHODS: Collected data included patient's name, age, sex, inpatient unit, laborato...
A molecular survey was conducted in Cochabamba, Bolivia, to characterize the mechanism involved in the resistance to clinically relevant antibiotics. Extended Spectrum β-lactamase encoding genes and plasmid-mediated quinolone resistance (PMQR) markers were investigated in a total of 101 oxyimino-cep...
Abstract The mechanisms involved in the uncommon resistance phenotype, carbapenem resistance and broad-spectrum cephalosporin susceptibility, were investigated in 25 Pseudomonas aeruginosa clinical isolates that exhibited this phenotype, which were recovered from three different hospitals located in São...

Abstract: Metallo-beta-lactamase production is an important mechanism for carbapenem resistance of Pseudomonas aeruginosa , which represents an emerging public health challenge. We report the case of a patient admitted to an intensive care unit, with sepsis caused by multidrug-resistant São Paulo Metall...
Objetivo: Caracterizar las infecciones de vías urinarias (IVU) producidas por enterobacterias productoras de betalactamasas de espectro extendido (BLEE) en Duitama (Colombia) durante 2010-2015. Metodología: Se realizó un estudio descriptivo en 2 instituciones prestadoras de salud a partir de los aisl...
ABSTRACT The present study evaluated the antimicrobial susceptibility profile, β-lactamase production, and genetic diversity of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. using phenotypic identification, antimicrobial susceptibility testing, and β-lactamase phenotypic detection....
Among its innumerous applications in Bacteriology, the Matrix-Assisted Laser Desorption Ionization-Time of
Flight Mass Spectrometry (MALDI-TOF MS) technique is evolving as a powerful tool for bacterial identification
and antimicrobial resistance investigation. Publications have evaluated the MALDI-TOF MS...
ABSTRACT During the last 30 years there has been a dissemination of plasmid-mediated β-lactamases in Enterobacteriaceae in Brazil. Extended spectrum β-lactamases (ESBL) are widely disseminated in the hospital setting and are detected in a lower frequency in the community setting. Cefotaximases ...
