Etiology and pathogenesis of bloodstream infections associated with the use of long-term central vascular catheter (CVC) in patients who undergone gastrointestinal surgery BJID
Brito,Cristiane Silveira; Gondim,Bruna Amâncio; Diogo Filho,Augusto; Gontijo Filho,Paulo P..
CVC is the main factor of risk of bloodstream infections. This study purpose was determining both etiology and pathogenesis of these infections in 80 patients who undergone gastrointestinal surgery and who worn long lasting CVC, in the institution HC-UFU. Cultures were made in nostril, skin of the insertion site, tip and catheter hub, in addition to hemoculture in those suspects of sepsis. The colonization incidence rate of the catheter tip was 12.5/ 1,000 catheter days and the CVC associate infection rate was 3.1/1,000 catheter days. Frequencies of skin, hub and catheter tip colonization were 13.8%, 8.9% and 13.3%, respectively. Coagulase-negative Staphylococci were the most found microorganisms in nostril (74%), skin (45.4%) and hub (75%) and...

Direct matrix-assisted laser desorption ionization time-of-flight mass spectrometry and real-time PCR in a combined protocol for diagnosis of bloodstream infections: a turnaround time approach BJID
Quiles,Milene Gonçalves; Boettger,Bruno Cruz; Inoue,Fernanda Matsiko; Monteiro,Jussimara; Santos,Daniel Wagner; Ponzio,Vinicius; Carlesse,Fabianne; Cappellano,Paola; Carvalhaes,Cecilia Godoy; Pignatari,Antonio Carlos Campos.
ABSTRACT Bloodstream infections (BSIs) are serious infections associated with high rates of morbidity and mortality. Every hour delay in initiation of an effective antibiotic increases mortality due to sepsis by 7%. Turnaround time (TAT) for conventional blood cultures takes 48 h, forcing physicians to streamline therapy by exposing patients to broad-spectrum antimicrobials. Our objective was (1) to evaluate the accuracy and TAT of an optimized workflow combining direct matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) and in-house real-time polymerase chain reaction (PCR) for bacterial identification and antimicrobial resistance profiling directly from positive blood bottles for diagnosing bloodstream infections...

Nosocomial infections caused by Elizabethkingia meningoseptica: an emergent pathogen BJID
Pereira,Graziella H.; Garcia,Doroti de Oliveira; Abboud,Cely Saad; Barbosa,Vera Lucia de Barros; Silva,Paulo Sérgio Lucas da.
We hereby describe the clinical and epidemiological features and, outcomes of nine patients with Elizabethkingia meningoseptica infections in two hospitals over a 2-year period. All infections caused by this pathogen were nosocomial, or healthcare associated infections, in hemodialysis settings whereas none was correlated with hospital outbreaks.

Kara,Ahu; Devrim,İlker; Bayram,Nuri; Katipoğlu,Nagehan; Kıran,Ezgi; Oruç,Yeliz; Demiray,Nevbahar; Apab,Hurşit; Gülfidan,Gamze.
Background:Vancomycin-resistant enterococci colonization has been reported to increase the risk of developing infections, including bloodstream infections.Aim:In this study, we aimed to share our experience with the vancomycin-resistant enterococci bloodstream infections following gastrointestinal vancomycin-resistant enterococci colonization in pediatric population during a period of 18 months.Method:A retrospective cohort of children admitted to a 400-bed tertiary teaching hospital in Izmir, Turkey whose vancomycin-resistant enterococci colonization was newly detected during routine surveillances for gastrointestinal vancomycin-resistant enterococci colonization during the period of January 2009 and December 2012 were included in this study. All...

Epidemiology of healthcare-associated infections among patients from a hemodialysis unit in southeastern Brazil BJID
Albuquerque,Silvia Eduara Kennerly de; Cavalcante,Ricardo de Souza; Ponce,Daniela; Fortaleza,Carlos Magno Castelo Branco.
Patients submitted to hemodialysis are at a high risk for healthcare-associated infections (HAI). Presently there are scarce data to allow benchmarking of HAI rates in developing countries. Also, most studies focus only on bloodstream infections (BSI) or local access infections (LAI). Our study aimed to provide a wide overview of HAI epidemiology in a hemodialysis unit in southeastern Brazil. We present data from prospective surveillance carried out from March 2010 through May 2012. Rates were compared (mid-p exact test) and temporally analyzed in Shewhart control charts for Poisson distributions. The overall incidence of BSI was 1.12 per 1000 access-days. The rate was higher for patients performing dialysis through central venous catheters (CVC), either...

Complete substitution of the Brazilian endemic clone by other methicillin-resistant Staphylococcus aureus lineages in two public hospitals in Rio de Janeiro, Brazil BJID
Chamon,Raiane Cardoso; Ribeiro,Sthefanie da Silva; Costa,Thaina Miranda da; Nouér,Simone Aranha; Santos,Katia Regina Netto dos.
Abstract Staphylococcus aureus is an important cause of bloodstream infections. Therefore, the main purpose of this work was to characterize a collection of 139 S. aureus isolates from bloodstream infections in two public hospitals in relation to their antimicrobial susceptibility profile, staphylococcal cassette chromosome mec types, and clonal relationship. Methicillin resistance and resistance to other 12 agents were accessed by the disk diffusion test. Minimum inhibitory concentration to mupirocin was also determined. The SCCmec types were accessed by multiplex PCR, and the clonal relationship was determined by pulsed field gel electrophoresis method and restriction modification system characterization. Besides, multilocus sequence typing was performed...

OBJECTIVE: The present studywas designed to evaluate the molecular epidemiology of CTX-M producing Klebsiella pneumoniae, Enterobacter cloacae and Escherichia coli isolated from bloodstream infections at tertiary care hospitals in the State of Rio de Janeiro, Brazil. MATERIAL AND METHODS: A total of 231 nonduplicate Enterobacteriaceae were isolated from five Brazilian hospitals between September 2007 and September 2008. The antimicrobial susceptibility testing was performed by disk diffusion method according to the Clinical Laboratory Standard Institute. Isolates showing resistance to third-generation cephalosporins were screened for ESBL activity by the double-disk synergy test. The presence of blaCTX-M , blaCTX-M-15 and blaKPC genes was determined by...

Clinical and microbiological characteristics of bloodstream infections in a tertiary hospital in Maceió, Alagoas, Brazil BJID
Tenório,Maria Tereza Freitas; Porfírio,Zenaldo; Lopes,Antonio Carlos; Cendon,Sonia.
We observed the clinical and microbiological characteristics of several stages of bloodstream infections (BSI), as well as the mortality attributed to it in a tertiary hospital in the northeast of Brazil (in the city of Maceió, Alagoas). A prospective cohort of 143 patients who had at least one positive blood culture was enrolled in the study. Their clinical evolution was followed up for 30 days from October 2005 to December 2006. The relation among the qualitative variables was verified through Chi-square test. The significance level was 5%. The statistical package adopted was SPSS 15.0 for Windows. Up to the thirtieth day, 30.1% of the patients presented bacteremia and 69.9% developed sepsis.Among these, 20.3% developed severe sepsis and 10.5% septic...
