Prevalencia de β -lactamasas de espectro extendido en enterobacterias causantes de sepsis neonatal y factores asociados

Rev. chil. infectol; 36 (4), 2019
Resumen Introducción: Las infecciones causadas por enterobacterias productoras de β-talactamasas de espectro extendido (EP-BLEE) tienen implicaciones sobre la morbilidad y mortalidad neonatal. Objetivo: Describir la prevalencia de EP-BLEE en sepsis neonatal y los factores asociados. Métodos: Es...

Complete genome sequence of human pathogen Kosakonia cowanii type strain 888-76T

Braz. j. microbiol; 49 (1), 2018
ABSTRACT Kosakonia cowanii type strain 888-76T is a human pathogen which was originally isolated from blood as NIH group 42. In this study, we report the complete genome sequence of K. cowanii 888-76T. 888-76T has 1 chromosome and 2 plasmids with a total genome size of 4,857,567 bp and C+G 56.15%. This g...

Comparative genomics reveals diverse capsular polysaccharide synthesis gene clusters in emerging Raoultella planticola

Mem. Inst. Oswaldo Cruz; 113 (10), 2018
Raoultella planticola is an emerging zoonotic pathogen that is associated with rare but life-threatening cases of bacteremia, biliary tract infections, and urinary tract infections. Moreover, increasing antimicrobial resistance in the organism poses a potential threat to public health. In spite of its im...

Estudio de susceptibilidad a cefalosporinas de primera generación en enterobacterias aisladas de urocultivo, según criterios CLSI y EUCAST

Rev. chil. infectol; 35 (3), 2018
Resumen Actualmente se recomienda el uso de cefazolina para determinar la susceptibilidad a cefalosporinas orales de primera generación en cepas de enterobacterias en ITU no complicada. Nuestro objetivo fue establecer la susceptibilidad a cefalosporinas orales en cepas urinarias según puntos de corte p...

Ceftolozane-tazobactam activity against drug-resistant Enterobacteriaceae and Pseudomonas aeruginosa causing healthcare-associated infections in Latin America: report from an antimicrobial surveillance program (2013-2015)

Braz. j. infect. dis; 21 (6), 2017
ABSTRACT This study evaluated the in vitro activity of ceftolozane-tazobactam and comparator agents tested against Latin American isolates of Enterobacteriaceae and Pseudomonas aeruginosa from patients with health care-associated infections. Ceftolozane-tazobactam is an antipseudomonal cephalosporin comb...

The Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) identification versus biochemical tests: a study with enterobacteria from a dairy cattle environment

Braz. j. microbiol; 48 (1), 2017
Abstract Mastitis adversely affects milk production and in general cows do not regain their full production levels post recovery, leading to considerable economic losses. Moreover the percentage decrease in milk production depends on the specific pathogen that caused the infection and enterobacteria are ...

Phenotypic methods for screening carbapenem-resistant Enterobacteriaceae and assessment of their antimicrobial susceptibility profile

Abstract INTRODUCTION: In this study, we used phenotypic methods to screen carbapenem-resistant Enterobacteriaceae (CREs) and evaluated their antimicrobial sensitivity profile. METHODS: One hundred and seventy-eight CREs were isolated at a university hospital in south Brazil in a one-year period. Samp...

High prevalence rate of extended-spectrum beta-lactamases (ESBL) among Enterobacteriaceae in a small Brazilian public hospital

Braz. j. pharm. sci; 47 (4), 2011
The production of extended-spectrum beta-lactamases (ESBL) is considered one of the most important resistance mechanisms that impair antimicrobial treatment of infections caused by Enterobacteriaceae. Data on culture and susceptibility tests were collected from the Clinical Analyses and Research Laborato...

Expressäo do flagelo em sorotipos imóveis de Escherichia coli enteroinvasora

No presente estudo, a observação de dez sorotipos imóveis de EIEC em microscópio eletrônico levou à descoberta de flagelos em todos os sorotipos estudados, em quantidades que variaram de um a cinco filamentos. A produção do flagelo de EIEC (FLIEC) não foi influenciada pela temperatura, mas o ní...
