Método rápido para la detección de la sensibilidad a cefotaxima en enterobacterias
Rapid test for detection of susceptibility to cefotaxime in Enterobacteriaceae

Rev. argent. microbiol; 48 (4), 2016
En este trabajo se evalúa una prueba rápida in house para la detección de enterobacterias sensibles a cefotaxima, basada en el cambio de pH del rojo fenol debido a la hidrólisis de este antibiótico. Las cepas de enterobacterias procedentes de 1.947 urocultivos se evaluaron mediante los paneles Micro...

Clinical and microbiological characteristics of OXA-23- and OXA-143-producing Acinetobacter baumannii in ICU patients at a teaching hospital, Brazil

Braz. j. infect. dis; 20 (6), 2016
ABSTRACT Background: Carbapenem-resistant Acinetobacter baumannii (CRAb) is an important cause of nosocomial infections especially in intensive care units. This study aimed to assess clinical aspects and the genetic background of CRAb among ICU patients at a Brazilian teaching hospital. Methods: 56 cri...

Factores asociados a infecciones urinarias producidas por enterobacterias productoras de β -lactamasas de espectro extendido: una cohorte prospectiva

Rev. chil. infectol; 33 (6), 2016
Background: Urinary tract infections (UTIs) caused by extended-spectrum betalactamases (ESBL) are an increasingly common problem. Aim: To develop an association model to allow an early detection of ESBL-producing microorganisms. Methods: A prospective observational cohort study was undertaken among patie...

Relación clonal y detección del gen blaKPC en cepas de Klebsiella pneumoniae resistentes a carbapenémicos, en un hospital de Venezuela

Rev. chil. infectol; 33 (5), 2016
In order to study the clonal relationship and blaKPC gene detection in clinical isolates of Klebsiella pneumoniae resistant to carbapenems, we analyzed 22 clinical isolates of K. pneumoniae with resistance to imipenem and/ or meropenem, isolated in the laboratory of bacteriology at the University Hospita...

CTX-M extended-spectrum ß-lactamase-producing Klebsiella spp, Salmonella spp, Shigella spp and Escherichia coli isolates in Iranian hospitals

Braz. j. microbiol; 47 (3), 2016
Abstract This study was conducted in Iran in order to assess the distribution of CTX-M type ESBLs producing Enterobacteriaceae. From January 2012 to December 2013, totally 198 E. coli, 139 Klebsiella spp, 54 Salmonella spp and 52 Shigella spp from seven hospitals of six provinces in Iran were screened fo...

First report of TEM-104-, SHV-99-, SHV-108-, and SHV-110-producing Klebsiella pneumoniae from Iran

Abstract: INTRODUCTION: Extended-spectrum beta-lactamases (ESBLs) are bacterial enzymes capable of hydrolyzing beta-lactams. The aim of this study was to describe the prevalence of TEM- and SHV-type ESBL-producing Klebsiella pneumoniae strains in Zahedan, Southeast Iran. METHODS: A total of 170 non-rep...

Characterization of a small outbreak of Salmonella enterica serovar Infantis that harbour CTX-M-65 in Ecuador

Braz. j. infect. dis; 20 (4), 2016

Detecção de betalactamase de espectro estendido em isolados de enterobactérias provenientes de um hospital da Região de Santa Teresa-ES

A produção das chamadas Betalactamases de espectro estendido (ESBLs) entre membros da família Enterobacteriaceae tem se tornado comum, sendo cada vez mais identificadas em pacientes hospitalizados, o que representa um importante problema de saúde pública. Detectar a produção das enzimas ESBL em en...

Clinical and microbiological features of infections caused by Pseudomonas aeruginosa in patients hospitalized in intensive care units

Abstract: INTRODUCTION: The spread of multidrug-resistant Pseudomonas aeruginosa in Brazilian hospitals has greatly impacted upon the morbidity and mortality of individuals in intensive care units. Given the lack of information regarding the dynamics of multidrug resistance in northern Brazil, we analyz...

Occurrence and characteristics of extended spectrum beta-lactamases-producing Enterobacteriaceae from foods of animal origin

Braz. j. microbiol; 47 (2), 2016
Abstract Presence of extended spectrum beta-lactamases (ESBL) in bacteria is a growing health concern of global significance. The local, regional, national, and international epidemiological studies for extended spectrum beta-lactamases-producing Enterobacteriaceae and their encoding genes in foods are s...
