Etiología y resistencia a antimicrobianos de la infección no complicada del tracto urinario
Etiology and antimicrobial resistance of uncomplicated urinary tract infections

Medicina (B.Aires); 77 (4), 2017
La infección urinaria no complicada en mujeres es un motivo frecuente de consulta e indicación de antimicrobianos. El objetivo de este estudio fue definir etiología y resistencia a antimicrobianos en episodios de infección urinaria no complicada. Este estudio prospectivo incluyó mujeres premenopáus...

Phenol degradation and genotypic analysis of dioxygenase genes in bacteria isolated from sediments

Braz. j. microbiol; 48 (2), 2017
Abstract The aerobic degradation of aromatic compounds by bacteria is performed by dioxygenases. To show some characteristic patterns of the dioxygenase genotype and its degradation specificities, twenty-nine gram-negative bacterial cultures were obtained from sediment contaminated with phenolic compound...

Direct identification from positive blood broth culture by matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS)

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Bloodstream infections (BSIs) are among the most concerning bacterial infections. They are one of the leading causes of morbidity and mortality, and occur in 30-70% of critical care patients. The prompt identification of the causative microorganism can help choosing the appropriate antimicrobial...

Resistance among Gram-negative ESKAPE pathogens isolated from hospitalized patients with intra-abdominal and urinary tract infections in Latin American countries: SMART 2013-2015

Braz. j. infect. dis; 21 (3), 2017
ABSTRACT Gram-negative ESKAPE pathogens (Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) are important etiologic agents of nosocomial infection that are frequently resistant to broad-spectrum antimicrobial agents. Gram-negative ESKAPE pathogens were colle...

Etiología aerobia de apendicitis aguda en adultos: Estudio multicéntrico de la sepsis abdominal en Argentina
Aerobic etiology of acute appendicitis in adults. Multicenter study of abdominal sepsis in Argentina

Medicina (B.Aires); 77 (2), 2017
El tratamiento antibiótico de las apendicitis agudas se decide empíricamente basándose en la información epidemiológica. Las resistencias son variables entre regiones y los datos de Argentina son escasos. En el contexto de un estudio multicéntrico, observacional, de infecciones abdominales, se efec...

Evaluación de la susceptibilidad directa desde hemocultivos positivos utilizando el sistema Vitek 2: comparación de dos protocolos rápidos

Rev. chil. infectol; 34 (2), 2017
Antimicrobial susceptibility testing using Vitek® 2 (bioMérieux) cards inoculated directly from positive blood cultures was compared with the standard method for gramnegative rods. Two different protocols for the inoculum preparation were evaluated. Protocol 2 was faster and easier to perform. Rapid su...

Changes in the conjunctival bacterial flora of patients hospitalized in an intensive care unit

Arq. bras. oftalmol; 80 (1), 2017
ABSTRACT Purpose: To identify the changes in aerobic conjunctival bacterial flora and to correlate culture results with physical health and the duration of patients' hospitalization in an intensive care unit (ICU). Methods: Patients hospitalized in the ICU were included in this study. Conjunctival cult...

β-lactamase-producing Gram-negative bacteria in an intensive care unit in southern Brazil

ABSTRACT The present study evaluated the antimicrobial susceptibility profile, β-lactamase production, and genetic diversity of Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter spp. using phenotypic identification, antimicrobial susceptibility testing, and β-lactamase phenotypic detection....

Secondary bacterial isolates from previously untreated Buruli ulcer lesions and their antibiotic susceptibility patterns in Southern Nigeria

Abstract INTRODUCTION: Mycolactones, secreted by Mycobacterium ulcerans, were previously believed to prevent super infection in Buruli ulcer lesions. However, little is known about secondary bacterial infections in these lesions. This study evaluated contaminating bacterial flora and their antibiotic su...
