1. The occurrence of Aeromonas in drinking water, tap water and the Porsuk River
The occurrence of Aeromonas spp. in the Porsuk River, public drinking water and tap water in the City of Eskisehir (Turkey) was monitored. Fresh water samples were collected from several sampling sites during a period of one year. Total 102 typical colonies of Aeromonas spp. were submitted to biochemical tests for species differentiation and of 60 isolates w

2. Cross-transmission of vancomycin-resistant Enterococcus in patients undergoing dialysis and kidney transplant
The objective of this study was to investigate the occurrence of vancomycin-resistant Enterococcus (VRE) cross-transmission between two patient groups (long-term dialysis and kidney transplant patients). Molecular typing, by automated ribotyping with the RiboPrinter Microbial Characterization System (Qualicon, USA), was used to analyze VRE isolates from 31 f

3. Salmonella enteritidis de origem aviária: determinação de padrões de resistência antimicrobiana, detecção de mutação no gene gyrA de cepas resistentes ao ácido nalidíxico, fagotipagem e ribotipagem
Este trabalho foi conduzido com o objetivo de gerar dados de resistência a agentes antimicrobianos de Salmonella Enteritidis (SE) isoladas de amostras clínicas e do ambiente criatório de aves, nos anos de 1999, 2000 e 2001, de cortes de frango, no ano de 1996, ambos na região Sul, bem como de carcaças de frango, nos anos de 2004 e 2005, na região Norde

4. Isolation and identification of lactobacillus and bifidbacteria in probiotic foods avaliable in the brazilian market. / Isolamento e identificação de lactobacilos e bifidobacterias em alimentos probioticos disponiveis no mercado brasileiro.
In the period between March and May 2001, a series of lactic cultures were isolated from 11 different brand products purchased from regular retail outlets located in Campinas (SP, Brazil). The sample types collected included 3 yogurts, 5 fermented milks, 2 dairy beverages and 1 symbiotic dry mix. The strains were identified by phenotypic and genotypic charac

5. Comparison of an Automated Ribotyping System to Restriction Endonuclease Analysis and Pulsed-Field Gel Electrophoresis for Differentiating Vancomycin-Resistant Enterococcus faecium Isolates
The RiboPrinter Microbial Characterization System was compared with pulsed-field gel electrophoresis (PFGE), restriction endonuclease analysis (REA), and epidemiological data for typing 45 vancomycin-resistant Enterococcus faecium (VRE) isolates. In 21 clinically related isolates, 90 to 100% were similar by PFGE and REA, but only 57% were similar by the Ribo

6. Characterization of Members of the Legionellaceae Family by Automated Ribotyping
In order to implement a new and reliable method for characterizing different species of Legionella, a genetic fingerprinting study with an automated ribotyping system (RiboPrinter) was completed with members of this genus which were deposited at the American Type Culture Collection. The RiboPrinter examined the different patterns of EcoRI digestion fragments

7. Methicillin-Resistant Staphylococcus caprae in a Neonatal Intensive Care Unit
Staphylococcus caprae, a hemolytic coagulase-negative staphylococcus that is infrequently associated with humans, was initially detected in specimens from six infants in our neonatal intensive care unit due to phenotypic characteristics common to methicillin-resistant Staphylococcus aureus. These isolates were subsequently identified as S. caprae by the Auto

8. Evaluation of the Discriminatory Powers of the Dienes Test and Ribotyping as Typing Methods for Proteus mirabilis
A total of 63 clinical isolates of Proteus mirabilis collected over a 19-month period were typed by the Dienes test and ribotyping. Ribotyping was performed using the fully automated RiboPrinter Microbial Characterization System (Qualicon, Wilmington, Del.). Isolates that were indistinguishable by the Dienes test and/or ribotyping were characterized further

9. Automated Ribotyping Provides Rapid Phylogenetic Subgroup Affiliation of Clinical Extraintestinal Pathogenic Escherichia coli Strains
Using the automated Riboprinter system, we have initiated the construction of an electronic Riboprint database composed of 72 ECOR reference strains and 15 archetypal virulent strains in order to provide a new simple molecular characterization method. More than 90% of the ECOR strains clustered in their original phylogenetic group. All but one of the archety

10. Comparison of emm Typing and Ribotyping with Three Restriction Enzymes To Characterize Clinical Isolates of Streptococcus pyogenes
A total of 336 Streptococcus pyogenes isolates recently recovered from patients with pharyngitis from 13 countries were characterized by emm typing and riboprinting using an automated Riboprinter (Dupont/Qualicon) based on the patterns produced by three restriction enzymes, EcoRI, PstI, and HindIII. Three enzymes were necessary to increase the discrimination

11. Identification of Strains of Alcaligenes and Agrobacterium by a Polyphasic Approach
The number of stable discriminant biochemical characters is limited in the genera Alcaligenes and Agrobacterium, whose species are consequently difficult to distinguish from one another by conventional tests. Moreover, genomic studies have recently drastically modified the nomenclature of these genera; for example, Alcaligenes xylosoxidans was transferred to

12. Comparison of Rapid, Automated Ribotyping and DNA Macrorestriction Analysis of Burkholderia pseudomallei
An automated ribotyping device (RiboPrinter) was used to determine the ribotypes of a collection of Burkholderia pseudomallei isolates. In a preliminary evaluation with the restriction enzymes BamHI and EcoRI, the protocol with EcoRI was more discriminating. The reproducibilities of the ribotypes obtained with EcoRI (EcoRI ribotypes) were determined by testi
