13. Antimicrobial resistance profiles of enterococci isolated from poultry meat and pasteurized milk in Rio de Janeiro, Brazil
The enterococci are important nosocomial pathogens with a remarkable capacity of expressing resistance to several antimicrobial agents. Their ubiquitous nature and resistance to adverse environmental conditions take account for their ability to colonize different habitats and for their potential for easy spreading through the food chain. In the present study

14. Diversidade genética e resistência aos antimicrobianos de amostras de enterococos isoladas na região Sul do Brasil
Foram estudadas 455 amostras de enterococos isolados de pacientes moradores da cidade de Porto Alegre, Rio Grande do Sul, Brasil, durante o período de julho 1996 a junho 1997 e foram identificados ao nível de espécies por testes fisiológicos convencionais e analisados sua susceptibilidade aos agentes antimicrobianos. A diversidade genética foi avaliada

15. Sensibilidade aos antimicrobianos entre amostras de Enterococcus isolados na cidade de Porto Alegre, RS, Brasil
A resistência a várias classes de agentes antimicrobianos é uma característica marcante dos enterococos observada em diferentes regiões geográficas. Informações sobre amostras isoladas na região sul do Brasil ainda são limitadas. No presente estudo, 455 enterococos isolados consecutivamente de pacientes moradores na cidade de Porto Alegre, Brasil,

17. Detection of pathogenic bacteria in skin lesions of patients with chiclero's ulcer: reluctant response to antimonial treatment
We investigated the bacterial flora present in skin lesions of patients with chiclero's ulcer from the Yucatan peninsula of Mexico using conventional culture methods (11 patients), and an immunocolorimetric detection of pathogenic Streptococcus pyogenes (15 patients). Prevalence of bacteria isolated by culture methods was 90.9% (10/11). We cultured, from chi

18. Diversity of Domain V of 23S rRNA Gene Sequence in Different Enterococcus Species
The highly conserved central loop of domain V of 23S RNA (nucleotides 2042 to 2628; Escherichia coli numbering) is implicated in peptidyltransferase activity and represents one of the target sites for macrolide, lincosamide, and streptogramin B antibiotics. DNA encoding domain V (590 bp) of several species of Enterococcus was amplified by PCR. Twenty enteroc

19. Evaluation of MicroScan for identification of Enterococcus species.
Emerging drug resistance of the enterococci necessitates differentiation from group D streptococci and accurate species identification. MicroScan (Baxter Healthcare Corp., West Sacramento, Calif.) has recently developed a microdilution system for identification and antibiotic susceptibility testing of gram-positive cocci. To evaluate the ability of this syst

20. Apparent Increased Prevalence of High-Level Aminoglycoside-Resistant Enterococcus durans Resulting from False Identification by a Semiautomated Software System
Identification of enterococci by using a semiautomated system (PASCO; Difco Laboratories, Detroit, Mich.) in the AHEPA University Hospital, Thessaloniki, Greece, revealed a high proportion of Enterococcus durans, particularly among isolates highly resistant to gentamicin and streptomycin. When 14 isolates were further tested by a conventional biochemical sch

21. Pseudo-outbreak of Enterococcus durans infections and colonization associated with introduction of an automated identification system software update.
Enterococci are an important cause of hospital-acquired infections. Since 1989, there has been an increase in the number of nosocomial enterococcal infections caused by strains resistant to vancomycin in the United States. Although many enterococcal species can colonize humans, only Enterococcus faecalis, E. faecium, E. raffinosus, and E. casseliflavus have

22. Acidification of methyl-alpha-D-glucopyranoside: a useful test to differentiate Enterococcus casseliflavus and Enterococcus gallinarum from Enterococcus faecium species group and from Enterococcus faecalis.
Enterococcus gallinarum and E. casseliflavus are difficult to differentiate from other enterococci, particularly E.faecium. The former two species were found to produce acid from methyl-alpha-D-glucopyranoside in phenol red broth, while E.faecalis strains and strains of the E.faecium species group, including E.faecium, E.durans, E. hirae, and E.mundtii, fail

23. Application of tRNA Intergenic Spacer PCR for Identification of Enterococcus Species
tRNA intergenic spacer PCR (tDNA-PCR) was evaluated for its usefulness in the differentiation of enterococcal species of human and animal origin. This technique was carried out for 124 strains belonging to 17 enterococcal species and generated DNA fragments, which were separated by capillary electrophoresis. tDNA-PCR enabled us to discriminate for all specie

24. Identification of Enterococcus Species and Phenotypically Similar Lactococcus and Vagococcus Species by Reverse Checkerboard Hybridization to Chaperonin 60 Gene Sequences
Data from four recent studies (S. H. Goh et al., J. Clin. Microbiol. 36:2164–2166, 1998; S. H. Goh et al., J. Clin. Microbiol. 34:818–823, 1996; S. H. Goh et al., J. Clin. Microbiol. 35:3116–3121, 1997; A. Y. C. Kwok et al., Int. J. Syst. Bacteriol. 49:1181–1192, 1999) suggest that an approximately 600-bp region of the chaperonin 60 (Cpn60) gene, amp
