1. Maldi-tof mass spectrometry for the identification and detection of antimicrobial activity of lactic acid bacteria isolated from local cheeses
Abstract In this study, 21 traditionally made cheeses were used. A total of 150 lactic acid bacteria (LAB) isolates were obtained from cheeses. 100 of them were identified at genus levels as Leunoconostoc (10), Lactobacillus (46) and Enterococcus (44) using biochemical tests. 71 strains were identified as Enterococcus durans (6), E. faecalis (18), E. faeciu

2. Microbial characterization and diversity of artisanal Ranchero cheese with emphasis in Lactococcus strains
Abstract The aim of this work is to characterize the natural microflora of artisanal Ranchero cheese and to identify Lactococcus isolates. Ten artisanal Ranchero cheese samples made with raw milk were obtained from local producers located in different geographical areas. Aerobic mesophilic, Staphylococci, Psychrophilic , total coliforms, molds, yeast and, l

3. Molecular characterization of microbial contaminants isolated from Umbilical Cord Blood Units for transplant
ABSTRACT Disposal of Umbilical Cord Blood Units due to microbial contamination is a major problem in Cord Blood Banks worldwide as it reduces the number of units available for transplantation. Additionally, economic losses are generated as result of resources and infrastructure used to obtain such units. Umbilical Cord Blood Units that showed initial microbi

4. Enterococcus spp. isolated from root canals with persistent chronic apical periodontitis in a Chilean population
Abstract Aim: To isolate and identify in a Chilean population,Enterococcus spp. from root canals with persistent chronic apical periodontitis (CAP) and to investigate the potential correlation between the bacteria and the observed clinical features. Methods: Twenty patients with indication for endodontic retreatment due to persistent CAP were selected. Dat

5. Performance of the Vitek 2 system software version 5.03 in the bacterial identification and antimicrobial susceptibility test: evaluation study of clinical and reference strains of Gram-positive cocci
Introduction. The genera Enterococcus, Staphylococcus and Streptococcus are recognized as important Gram-positive human pathogens. The aim of this study was to evaluate the performance of Vitek 2 in identifying Gram-positive cocci and their antimicrobial susceptibilities. Methods. One hundred four isolates were analyzed to determine the accuracy of the au

6. The genus Enterococcus as probiotic: safety concerns
Species from the genus Enterococcus have been used as probiotic for humans or animals, although this genus is not considered "generally recognized as safe" (GRAS). While enterococci are considered "positive" in food technology, isolates of this genus have emerged as opportunistic pathogens for the humans. The aim of this review is to summarize the characteri

7. Species distribution and antimicrobial susceptibility of enterococci isolated from broilers infected experimentally with Eimeria spp and fed with diets containing different supplements
Resistant bacteria in animal can be spread to environment and to humans. Poultry feed and infections caused by Eimeria spp. are important factors in determining the intestinal microbial communities. The aim of this study was to verify the prevalence of species and antimicrobial susceptibility of Enterococcus isolated from broilers fed with different suppleme

8. Bacteria of the genus Enterococcus in coalho cheese : influence of the processing on microbial selection, technological profile and implications in food safety / Bacterias do genero Enterococcus em queijo de coalho : influencia do processamento na seleção microbiana, perfil tecnologico e implicações em segurança de alimentos
Bacteria of the genus Enterococcus occur naturally as a lactic microbiota in a variety of chesses. This presence may be related to contamination however may have positive character due to the technological properties described for the genus. This work aimed to evaluate the influence of coalho cheese processing in the selection of bacteria of the genus Entero

9. Identification, antimicrobial resistance and genotypic characterization of enterococcus spp. isolated in Porto Alegre, Brazil
In the past two decades the members of the genus Enterococcus have emerged as important nosocomial pathogens worldwide. In the present study, we evaluated the antimicrobial resistance and genotypic characteristics of 203 Enterococcus spp. recovered from different clinical sources from two hospitals in Porto Alegre, Rio Grande do Sul, Brazil. The species were

10. Enterococcus gallinarum carrying the vanA gene cluster: first report in Brazil
In 2000, Enterococcus faecalis resistant to vancomycin was first reported at a tertiary hospital in Porto Alegre, southern Brazil. The resistance spread to other hospitals and surveillance programs were established by hospital infection committees to prevent the spread of vancomycin-resistant enterococci. In February 2002, an isolate initially identified at

11. 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

12. Isolation and identification of Lactobacillus spp., Bifidobacterium spp., Enterococcus spp., Pediococcus spp. and Lactococcus spp. from the intestinal microbiota of Blue-fronted Parrot (Amazona aestiva) / Isolamento e identificação de Lactobacillus spp., Bifidobacterium spp., Enterococcus spp., Pediococcus spp. e Lactococcus spp. da microbiota intestinal de Papagaio-verdadeiro (Amazona aestiva)
In Brazil, Blue-fronted Parrot (Amazona aestiva) has been widely owned as a pet bird and, therefore, one of the Brazilians birds most frequently traded illegally in the Black Market. There are few reports in the current literature regarding to the microbiota of wild birds. The gastrointestinal tract of these birds has a wide variety of bacterial species; mos
