Non-viral microbial keratitis in adults: clinical and laboratory aspects

Braz. j. microbiol; 49 (supl.1), 2018
Abstract This study compares patients with and without non-viral microbial keratitis in relation to sociodemographic variables, clinical aspects, and involved causative agent. Clinical aspects, etiology and therapeutic procedures were assessed in patients with and without keratitis that were diagnosed in...

Klebsiella pneumoniae productora de carbapenemasas en Perú: reporte de caso y discusión de la resistencia a los antimicrobianos

Medwave; 18 (2), 2018
Las carbapenemasas son uno de los mecanismos enzimáticos de resistencia antimicrobiana, que compromete la mayor parte de los antibióticos betalactámicos. Por lo general, su producción se debe al uso indiscriminado de antimicrobianos. A nivel mundial, la expansión de este mecanismo de resistencia es ...

Nuevas cefalosporinas

Rev. chil. infectol; 35 (5), 2018
Resumen La resistencia bacteriana se ha incrementado en América Latina y el mundo, por lo que se requiere investigación y creación de nuevos antimicrobianos capaces de erradicar a los microorganismos resistentes. Se realizó una revisión acerca de nuevas cefalosporinas y sus combinaciones con un inhi...

Sepsis neonatal tardía nosocomial en una unidad de terapia intensiva: agentes etiológicos y localización más frecuente

Rev. chil. infectol; 35 (5), 2018
Resumen Introducción: La sepsis neonatal nosocomial (SNN) es una entidad frecuente en las unidades de cuidados intensivos, donde causa una gran morbimortalidad. La ubicación más frecuente es bacteriemia, seguido de neumonía asociada a ventilador mecánico y vía urinaria. Objetivo: Conocer la etiol...

Epidemiología de las infecciones urinarias asociadas a catéter y no asociadas a catéter en un hospital universitario de tercer nivel

Rev. chil. infectol; 35 (3), 2018
Resumen Introducción: Las infecciones urinarias asociadas a la atención de la salud (ITU-AAS) representan un importante problema sanitario, siendo poco conocidas sus características cuando no están asociadas a cateterización urinaria u ocurren fuera de unidades de cuidados intensivos (UCI). Objeti...

Do different strains of E. faecalis have the same behavior towards intracanal medications in in vitro research?

Abstract: The aim of this study was to evaluate the antimicrobial action of different endodontic pastes against Enterococcus faecalis ATCC 29212, isolated from the urinary tract, and compare the action with E. faecalis ATCC 4083, isolated from the root canal. For this purpose, dentin blocks were infected...

Detection of blaNDM-1 in Stenotrophomonas maltophilia isolated from Brazilian soil

Mem. Inst. Oswaldo Cruz; 113 (6), 2018
This study reports the presence of the blaNDM-1 gene in an isolate of Stenotrophomonas maltophilia obtained from a Brazilian soil, inside an IncA/C plasmid with ~ 45 Kb. To the best of our knowledge, this is the second report in the world and the first in Brazil of NDM-producing bacterium isolated from s...

Characterization of avian pathogenic Escherichia coli isolated from free-range helmeted guineafowl

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Avian pathogenic Escherichia coli (APEC) isolates from apparently healthy free range helmeted guineafowl were characterized. Most of them had a high frequency of virulence associated genes, multi drug resistance and high pathogenicity. We demonstrated that helmeted guineafowl have potential to t...

Detection of virulence and β-lactamase encoding genes in Enterobacter aerogenes and Enterobacter cloacae clinical isolates from Brazil

Braz. j. microbiol; 49 (supl.1), 2018
ABSTRACT Enterobacter cloacae and E. aerogenes have been increasingly reported as important opportunistic pathogens. In this study, a high prevalence of multi-drug resistant isolates from Brazil, harboring several β-lactamase encoding genes was found. Several virulence genes were observed in E. aero...

Analysis of the antimicrobial and anti-caries effects of TiF4 varnish under microcosm biofilm formed on enamel

J. appl. oral sci; 26 (), 2018
Abstract Titanium tetrafluoride (TiF4) is known for interacting with enamel reducing demineralization. However, no information is available about its potential antimicrobial effect. Objectives This study evaluated the antimicrobial and anti-caries potential of TiF4 varnish compared to NaF varnish, chlor...
