1. Detection of vancomycin-resistant enterococci (VRE) in stool specimens submitted for Clostridium difficile toxin testing
Abstract The aim of this study was to determine the association between Clostridium difficile (C. difficile) and vancomycin-resistant Enterococcus (VRE) and efficacy of screening stools submitted for C. difficile toxin assay for prevalence of VRE. Between April 2012 and February 2014, 158 stool samples submitted for C. difficile toxin to the Marmara Universi

2. Comparison of culture and PCR methods in the diagnosis of bacterial meningitis
Abstract Our aim in this study is to compare the standard culture method with the multiplex PCR and the Speed-Oligo® Bacterial Meningitis Test (SO-BMT) – a hybridization-based molecular test method – during the CSF examination of the patients with the pre-diagnosis of acute bacterial meningitis. For the purposes of this study, patients with acute bacter

3. Response of Rhodococcus erythropolis strain IBBPo1 to toxic organic solvents
Abstract Recently, there has been a lot of interest in the utilization of rhodococci in the bioremediation of petroleum contaminated environments. This study investigates the response of Rhodococcus erythropolis IBBPo1 cells to 1% organic solvents (alkanes, aromatics). A combination of microbiology, biochemical, and molecular approaches were used to examine

4. Psychrotrophic bacteria in milk: How much do we really know?
The occurrence of psychrotrophic bacteria in raw milk is studied worldwide due to the difficulties associated with controlling their growth during cold storage and the consequent negative effects upon fluid milk or dairy products. Among the psychrotrophic bacteria, the genus Pseudomonas (represented primarily by P. fluorescens) has been highlighted as the ca

5. Application of MALDI-TOF MS for requalification of a Candida clinical isolates culture collection
Microbial culture collections underpin biotechnology applications and are important resources for clinical microbiology by supplying reference strains and/or performing microbial identifications as a service. Proteomic profiles by MALDI-TOF MS have been used for Candida spp. identification in clinical laboratories and demonstrated to be a fast and reliable t

6. Phenotypic, molecular and antimicrobial susceptibility assessment in isolates from chronic ulcers of cured leprosy patients: a case study in Southern Brazil
BACKGROUND:One of the most stigmatizing physical sequelaeof leprosy in cured patients is the development of chronic lower extremity ulcers. The bacterial diversity present in ulcers is considered one of the factors that can delay the healing process, as well as serve as a focus for severe secondary infections.OBJECTIVE:To identify the microbiota and antimicr

7. Análise e caracterização molecular, estrutural e populacional de proteases de HIV-1 do Estado de São Paulo. / Molecular, structural and populational analysis and characterization of HIV-1 proteases at Sao Paulo state.
Apesar dos esforços para controlar a infecção por HIV-1, na América do Sul, diversos recombinantes tem sido descritos, principalmente entre os subtipos B e F. Durante a tarefa coordenada de HIV-1 VGDN, foram encontrados diversos novos recombinantes BF no estado de São Paulo, sendo a maioria deles com a protease F. Técnicas filogenéticas usadas em inte

8. A procura de bactérias degradadoras de metamidofós. / Searching for methamidofos degrading bacteria.
Methamidophos is a strong acetylcholinesterase inhibitor and, therefore, a very toxic organophosphorus insecticide. This product has been widely employed for pest control in a variety of cultures, but little information is available about its biodegradation. 12 bacteria were isolated and characterized, from water and soil samples obtained from a site contami

10. 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

11. Microbial deterioration of vacuum-packaged chilled beef cuts and techniques for microbiota detection and characterization: a review
Gas production from microbial deterioration in vacuum-packs of chilled meat leads to pack distension, which is commonly referred as blown pack. This phenomenon is attributed to some psychrophilic and psychrotrophic Clostridium species, as well as Enterobacteria. The ability of these microorganisms to grow at refrigeration temperatures makes the control by th
