Isolation of blaNDM-producing Enterobacteriaceae in a public hospital in Salvador, Bahia, Brazil BJID
Barberino,Maria Goreth; Cruvinel,Silvia de Araujo; Faria,Célio; Salvino,Marco Aurélio; Silva,Marcio de Oliveira.
ABSTRACT Carbapenemases have great importance in the global epidemiological scenario since infections with carbapenemase-producing bacteria are associated with high mortality, especially in hospitalized patients in intensive care units. This study describes two microorganisms producers of the New Delhi Metallo-b-lactamase, Klebsiella pneumoniae and Citrobacter freundii, from two patients admitted to a public hospital in Salvador, Bahia. These are the first clinical cases of New Delhi Metallo-b-lactamase described in microorganisms in the north and northeast Brazil. The isolates were characterized by antimicrobial susceptibility test, with resistance to all β-lactams including carbapenems, negative Modified Hodge Test and the synergy test with...

Direct identification from positive blood broth culture by matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF MS) BJID
Barberino,Maria Goreth; Silva,Marcio de Oliveira; Arraes,Ana Carolina Palmeiras; Correia,Luís Cláudio; Mendes,Ana Verena.
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 therapy that will lead to better clinical outcomes. Blood culture is one of the most relevant tests for microbiological diagnosis of bacterial infections. The introduction of the MALDI-TOF microbiological diagnosis significantly decreased the time of identifying microorganisms. However, it depends on the growth on solid culture medium. In this study, 538 bottles of positive blood cultures were evaluated to test the accuracy of an in house modified...

Evaluation of blood stream infections by Candida in three tertiary hospitals in Salvador, Brazil: a case-control study BJID
Barberino,Maria Goreth; Silva,Nanci; Rebouças,Carla; Barreiro,Katarine; Alcântara,Ana Paula; Netto,Eduardo M.; Albuquerque,Lígia; Brites,Carlos.
Invasive infections caused by Candida spp. are an important problem in immunocompromised patients. There is scarce data on the epidemiology of blood stream candidiasis in Salvador, Brazil. This study evaluates the risk factors associated with candidemia, among patients admitted to three tertiary, private hospitals, in Salvador, Brazil. We conducted a case-control, retrospective study to compare patients with diagnosis of candidemia in three different tertiary hospitals in Salvador, Brazil. Patients were matched for nosocomial, acquired infections, according to the causal agent: cases were defined by positive blood cultures for Candida species. Controls were those patients who had a diagnosis of systemic bacterial infection, with a positive blood culture to...
