OBJECTIVES To analyse the ongoing epidemiology of KPC-producing Enterobacteriaceae after a non-ST258 KPC-3-producing Klebsiella pneumoniae outbreak in a university hospital in Madrid, Spain. METHODS Enterobacterial isolates (one per patient based on bacterial identification and typing patterns) with carbapenem MICs higher than the EUCAST epidemiological cut-off values, a positive modified Hod...

The present study aims to detect the production of extended-spectrum beta-lactamases (ESBL) by enterobacteria isolated from samples of fresh shrimp and fish obtained from the retail trade of the city of Sobral, Ceará State, Brazil. All bacterial isolates were submitted to identification and antimicrobial susceptibility testing using aminopenicillin, beta-lactamase inhibitors, carbapenem, 1st, 2...

INTRODUCTION Plasmid-mediated quinolone resistance (PMQR) is a growing clinical concern worldwide. The main aims of this study were to detect qnr-encoding genes and to evaluate the clonal relatedness of qnr-positive Enterobacter cloacae isolates. METHODS A total of 116 E. cloacae isolates that were not susceptible to quinolone were obtained from seven hospitals in Tehran, five hospitals in Qa...

Diacetyl, a high value product that can be extensively used as a food ingredient, could be produced from the non-enzymatic oxidative decarboxylation of α-acetolactate during 2,3-butanediol fermentation. In this study, the 2,3-butanediol biosynthetic pathway in Enterobacter cloacae subsp. dissolvens strain SDM, a good candidate for microbial 2,3-butanediol production, was reconstructed for diace...

In December 1992, Enterobacter cloacae was isolated from the oropharynx and respiratory tract of six ventilated neonates hospitalized in the intensive care unit (ICU) of our hospital. To establish the spread of the outbreak, 41 strains of E. cloacae were analyzed for genotypic markers by three methods: plasmid profile analysis, ribotyping with EcoRI or PvuII endonuclease, and arbitrarily primed...

OBJECTIVES To perform the first multinational Enterobacter cloacae clonality study, using the MLST scheme newly developed in Japan. METHODS The analysis included 195 rectal carriage E. cloacae isolates resistant to expanded-spectrum cephalosporins (ESCs), collected from patients in 12 hospital units across Europe and Israel. All of the isolates were typed by PFGE and 173 isolates were subject...

Neonatal septicaemia (NS) is a haunting problem for neonatologists all over the world with considerable morbidity and mortality. The bacteriological profile of NS is constantly changing along with the source of infection. This clinical entity is more commonly associated with preterm and low birthweight babies. In the Indian scenario, members of Enterobacteriaceae continue to be a challenging pr...

AIMS To evaluate the interaction between selected yeasts and bacteria and associate their metabolic activity with secondary cucumber fermentation. METHODS AND RESULTS Selected yeast and bacteria, isolated from cucumber secondary fermentations, were inoculated as single and mixed cultures in a cucumber juice model system. Our results confirmed that during storage of fermented cucumbers and in ...

Recently, low-level quinolone resistance has been associated with DNA acquired from transferable plasmids. Several studies showed a worldwide dissemination of QnrA determinants among enterobacterial isolates (1, 5). However, the presence of the qnr gene in clinical isolates from outpatients has not been hitherto reported for Brazil. The aim of this study was to determine the occurrence of the q...

Electricity can be directly generated by bacteria in microbial fuel cells (MFCs) from many different biodegradable substrates. When cellulose is used as the substrate, electricity generation requires a microbial community with both cellulolytic and exoelectrogenic activities. Cellulose degradation with electricity production by a pure culture has not been previously demonstrated without additio...
