Avaliação microbiológica de superfícies em terapia intensiva: reflexões sobre as estratégias preventivas de infecções nosocomiais

Objetivo: determinar o perfil microbiológico de bactérias isoladas e identificadas nos leitos e bombas infusoras na unidade de terapia intensiva de um hospital universitário do Estado do Rio de Janeiro. Método: foram coletadas nove amostras de grades das camas dos pacientes e oito de teclados de bomb...

Time of catheter removal in candidemia and mortality

Braz. j. infect. dis; 22 (6), 2018
ABSTRACT Background: The impact of central venous catheter (CVC) removal on the outcome of patients with candidemia is controversial, with studies reporting discrepant results depending on the time of CVC removal (early or any time during the course of candidemia). Objective: Evaluate the effect of tim...

Increasing prevalence and dissemination of invasive nontyphoidal Salmonella serotype Typhimurium with multidrug resistance in hospitalized patients from southern Brazil

Braz. j. infect. dis; 22 (5), 2018
ABSTRACT Introduction: Nontyphoidal Salmonella serotypes are the main cause of human food-borne infection, including several hospitalization cases in the developing countries. Aim: To detect the main serotypes and to characterize the antibiotic resistance of human non-enteric and enteric nontyphoidal S...

Ralstonia mannitolilytica bacteremia in a neonatal intensive care unit

Abstract Ralstonia mannitolilytica, a Gram-negative bacterium, is rarely isolated in clinical laboratories. It has been associated with outbreaks due to its ability to survive in liquid media and hospital devices. We describe three cases of bacteremia caused by R. mannitolilytica in a neonatal intensive ...

Molecular analysis, biofilm formation, and susceptibility of methicillin-resistant staphylococcus aureus strains causing community- and health care-associated infections in central venous catheters

Abstract INTRODUCTION: The behavior of methicillin-resistant Staphylococcus aureus (MRSA) isolated from central venous catheter-related infection was evaluated to determine its biofilm potential, antimicrobial resistance, and adhesion genes. METHODS: A total of 1,156 central venous catheters (CVC) we...

Multidrug-resistant Acinetobacter baumannii clones persist on hospital inanimate surfaces

Braz. j. infect. dis; 22 (5), 2018
ABSTRACT Acinetobacter baumannii is one of the most frequent Gram-negative opportunistic pathogens associated with hospital-acquired infection worldwide. We briefly describe A. baumannii isolates that were recovered from surrounding ICU bed surfaces, exhibiting multidrug resistance phenotype and belongin...

Perfil microbiológico de neumonías asociadas a ventilación mecánica en el Hospital de Talca

Rev. méd. Maule; 33 (2), 2018
INTRODUCTION: Ventilator-associated pneumonia is the sixth nosocomial infection most frequent in Chile. Considering the high mortality associated in this infection, it is important to know the local agents and their respective resistances and susceptibilities to choose and appropriate management. OBJECTI...

Changes in antimicrobial susceptibility of commonly clinically significant isolates before and after the interventions on surgical prophylactic antibiotics (SPAs) in Shanghai

Braz. j. microbiol; 49 (3), 2018
Abstract Surveillances and interventions on antibiotics use have been suggested to improve serious drug-resistance worldwide. Since 2007, our hospital have proposed many measures for regulating surgical prophylactic antibiotics (carbapenems, third gen. cephalosporins, vancomycin, etc.) prescribing practi...

Inadequate use of antibiotics and increase in neonatal sepsis caused by resistant bacteria related to health care assistance: a systematic review

Braz. j. infect. dis; 22 (4), 2018
ABSTRACT Background Technologies and life support management have enhanced the survival of preterm infants. The immune system of newborns is immature, which contributes to the occurrence of healthcare-associated infections. The overlap of several conditions with neonatal sepsis and the difficulty of dia...

Ventilator-associated pneumonia agents in Brazilian Neonatal Intensive Care Units - a systematic review

Braz. j. infect. dis; 22 (4), 2018
ABSTRACT Introduction Ventilator-associated pneumonia (VAP) is one of the most common healthcare-associated infections (HAI) in neonates admitted in neonatal intensive care units (NICUs). Methods We did a systematic review using PRISMA methodology to identify the main etiological agents in Brazilian NI...
