13. Impact of the introduction of an automated microbiologic system on the clinical outcomes of bloodstream infections caused by Enterobacteriaceae strains
INTRODUCTION: Enterobacteriaceae strains are a leading cause of bloodstream infections (BSI). The aim of this study is to assess differences in clinical outcomes of patients with BSI caused by Enterobacteriaceae strains before and after introduction of an automated microbiologic system by the microbiology laboratory. METHODS: We conducted a retrospective coh

14. Shewanella infection of snake bites: a twelve-year retrospective study
OBJECTIVE: Infections of snake bite wounds by Shewanella are rarely discussed in the medical literature. This study aims to characterize the presentation and management of Shewanella infections in snake bite wounds. METHOD: We retrospectively investigated the microbiology, clinical features, and outcomes of patients with Shewanella infected snake bite wounds

15. Impacto da introdução do sistema microbiológico automatizado Phoenix na evolução clínica das infecções de corrente sanguínea hospitalares por Enterobacteriaceae / Impact of the introduction of the Phoenix automated microbiology system on clinical outcomes of nosocomial bloodstream infections caused by Enterobacteriaceae
The family Enterobacteriaceae is an important cause of bloodstream infections (BSI). The increasing antimicrobial resistance is a complicating factor in treating these infections, thus the minimum inhibitory concentration (MIC) plays a key role in the analysis of susceptibility. Until August 2007, the antimicrobial susceptibility testing (AST) of blood cultu

16. Epidemiologia e caracterização molecular do vírus da Influenza em quatro espécies de pinguins na Região Antártica. / Epidemiology and molecular characterization of the influenza virus in four penguin species of the antartic region.
Epidemics and pandemics of influenza usually refer to infections in human beings. The influenza virus is not, however, restricted to humans and can cause infirmity and death in other species including horses, swine, marine mammals, birds, and others. Ecological studies of viral infections have led to the hypothesis that the influenza viruses that attack mamm

17. Evaluation of different detection methods of biofilm formation in the clinical isolates
BACKGROUND: Microorganisms growing in a biofilm are associated with chronic and recurrent human infections and are highly resistant to antimicrobial agents. There are various methods to detect biofilm production like Tissue Culture Plate (TCP), Tube method (TM), Congo Red Agar method (CRA), bioluminescent assay, piezoelectric sensors, and fluorescent microsc

18. Atividade de ¦Â-carbolina-3-carb¨®xi e de derivados ¦Â-carbolina-3-carboxamida em Leishmania amazonensis
Leishmanioses são causadas por esp¨¦cies pertencentes ao g¨ºnero Leishmania e produzem grande impacto na sa¨²de p¨²blica, especialmente em pa¨ªses de clima tropical e subtropical. Infecções causadas por esp¨¦cies de Leishmania provocam um amplo espectro de doenças em humanos, com v¨¢rias manifestações c

19. Evaluation of oxacillin and cefoxitin disks for detection of resistance in coagulase negative staphylococci
Coagulase-negative Staphylococcus spp. was considered nonpathogenic until the emergence of multiresistance and the demonstration of their participation as infectious agents. In Brazil, oxacillin resistance may be present in over 80% of isolates, and the Clinical and Laboratory Standards Institute standardized a diskdiffusion method to predict this resistance

20. Structural studies of the Enterococcus faecalis SufU [Fe-S] cluster protein
Background: Iron-sulfur clusters are ubiquitous and evolutionarily ancient inorganic prosthetic groups, the biosynthesis of which depends on complex protein machineries. Three distinct assembly systems involved in the maturation of cellular Fe-S proteins have been determined, designated the NIF, ISC and SUF systems. Although well described in several organis

21. Estudo comparativo de fatores de virulência em isolados clínicos de Pseudomonas aeruginosa produtores e não produtores de metalo- ß-lactamase SPM-1
The invasion abilities, colonization and tissue damage presented by P. aeruginosa are due to the multiples virulence factors produced by the microorganism during the pathogenesis. Clinical isolates of SPM-1 metallo-β-lactamase Pseudomonas aeruginosa (SPM-1 MβL) from nosocomial infections present high rates morbidity and mortality and represent epid

23. Estudo da variabilidade genética e dos fatores de virulência de isolados de Ureaplasma diversum. / Study of genetic variability and virulence factors of Ureaplasma diversum isolates.
The aim of the present study was the study of genetic variability and virulence factors of U. diversum clinical isolates. The strains were submitted to sequencing for 16S rRNA and urease genes. Moreover, the strains were analyzed to the virulence factors: capsule, phospholipase C, IgA protease and adhesion and invasion into Hep-2 cells. The sequencing of par

24. Estudo epidemiólogico-molecular e de fatores de virulência de Staphylococcus aureus associados à mastite bovina em propriedades de exploração leiteira dos Estados de São Paulo e Pernambuco. / Molecular epidemiology and virulence factors of Staphylococcus aureus associated to bovine mastitis in dairy herds from São Paulo and Pernambuco state.
A total of 107 S. aureus isolated from bovine milk, udder skin, milkers and milking machine, from São Paulo and Pernambuco herds was typed by molecular techniques. PCR-RFLP coa gene and PCR spa gene distinguished six amplicons. All strains amplified coa, spa, icaA genes and, 69% produced in vitro glucose-induced biofilm. PFGE identified 31 pulsotypes, 12 li
