INTRODUCTION: Infections caused by β-lactamase-producing gram-negative bacteria, such
as Klebsiella pneumoniae, are increasing globally with high morbidity and mortality. The aim …

The present study describes integron mediated multiple antibiotic resistance in extended-
spectrum β-lactamase producing clinical isolates of Klebsiella pneumoniae. One hundred …

Twenty-eight Klebsiella pneumoniae clinical isolates that exhibited an extended-spectrum
cephalosporin-resistance profile from a city in the Northeast of Brazil were analysed by PCR …

SUMMARY OBJECTIVE: Beta-lactams resistance is a major clinical problem in treating
pneumonia. This study aimed to detect the extended-spectrum beta-lactamases (ESBL) …

Objectives The aim of this study was to characterize the KPC-type carbapenem-hydrolysing
β-lactamase, extended-spectrum β-lactamases (ESBLs) and class 1 integrons among …

INTRODUCTION: The prevalence of cephalosporins and carbapenem-resistant Klebsiella
pneumoniae strains is rising in Brazil, with potential serious consequences in terms of …

Introduction The high prevalence of Klebsiella pneumoniae infections is related to the ability
of K. pneumoniae to acquire and disseminate exogenous genes associated with mobile …

INTRODUCTION Antibiotic resistance in carbapenemase-producing Klebsiella pneumoniae
is acquired and disseminated mainly by plasmids. Therefore, we aimed to investigate the …

Introduction: The increasing incidence of multi-resistant microorganisms has been
considered a public health problem. One of the routines included in hospital practice is the …

AbstrAct Introduction: Infections caused by Gram negative bacteria, producing extended-
spectrum β-lactamase, including Klebsiella pneumoniae are increasing all over the world …
