conclusions our study showed that the prevalence of esbl-producing k. pneumoniae at king khalid hospital was significantly high. routine detection of esbl-producing microorganisms is required by each of the laboratory standard detection methods to control the spread of these infections and allow a proper therapeutic strategy. for detection, the phenotypic confirmatory disc diffusion test is sim...

BACKGROUND There is no information regarding the resistance mechanisms of extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae in community setting in Cameroon. The current study aimed to determine the proportion of ESBLs in Enterobacteriaceae isolated in the community and to analyse some risk factors associated with ESBL carriage. METHODS Faecal samples were collected from 208 d...

BACKGROUND Preterm infants are at high risk for extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E) sepsis and neonatal intensive care unit (NICU) outbreaks. Maternal colonization with ESBL-E may be precursory to maternal-neonatal transmission. However, there is no consensus regarding surveillance of pregnant women for ESBL-E colonization. AIM To identify pairs of mothers a...

INTRODUCTION Extended-spectrum β-lactamase (ESBL)-producing strains of Enterobacteriaceae are considered to be emerging pathogens. They are a major problem in hospitalized as well as community-based patients. Major outbreaks involving ESBL strains have been reported from all over the world. Recurrent urinary tract infection (UTI) is one of the risk factors for infection with ESBL-producing E. c...

BACKGROUND & OBJECTIVES Information about the genetic diversity of the extended-spectrum β-lactamases (ESBLs) and the clonal relationship of the organisms causing neonatal infections is limited, particularly from India where neonatal mortality is high. This study was undertaken to investigate the molecular epidemiology and risk factors associated with neonatal septicaemia caused by ESBL-produci...

The amperometric detection of extended-spectrum β-lactamase (ESBL) with carbon screen-printed sensors was investigated in the presence of the Nitrocefin, a commercially-available β-lactamase chromogenic cephalosporin substrate. Using an ESBL isolated from a clinical sample, it was shown for the first time that the intensity of a specific anodic pic current (EP = ∼+0.3 V vs. Ag/AgCl) resulting f...

In South Western Indian ocean (IO), Extended-Spectrum β-Lactamase producing Enterobacteriaceae (ESBL-E) are a main public health issue. In livestock, ESBL-E burden was unknown. The aim of this study was estimating the prevalence of ESBL-E on commercial farms in Reunion, Mayotte and Madagascar and genes involved. Secondly, risk factors of ESBL-E occurrence in broiler, beef cattle and pig farms w...

A case-control study, involving patients with positive blood cultures for Klebsiella pneumoniae (KP) or Escherichia coli (EC) EC and controls with positive blood cultures for non-ESBL-KP or EC, was performed to assess risk factors for extended-spectrum-beta-lactamase (ESBL) production from nosocomial bloodstream infections (BSIs). Mortality among patients with BSIs was also assessed. The study ...

OBJECTIVES To investigate the epidemiological and clinical findings of extended-spectrum beta-lactamase (ESBL)-producing Providencia stuartii infections in a large Italian university hospital. PATIENTS AND METHODS All consecutive episodes of P. stuartii infection that occurred during 1999-2002 were included in the study. For each patient, we recorded the area of hospitalization and drug susce...

To assess public health risks from environmental exposure to Extended-Spectrum β-Lactamases (ESBL)-producing bacteria, it is necessary to have insight in the proportion of relative harmless commensal variants and potentially pathogenic ones (which may directly cause disease). In the current study, 170 ESBL-producing E. coli from Dutch wastewater (n = 82) and surface water (n = 88) were characte...
