| phenotypic and genotypic characterization of clinical and intestinal enterococci isolated from inpatients and outpatients in two brazilian hospitals. | the phenotypic and genotypic characteristics of clinical and intestinal enterococcal isolates recovered from inpatients and outpatients of two brazilian hospitals, located in niterói city, rio de janeiro, brazil, were compared. a total of 601 strains were studied, including 253 isolated from different clinical sources and 348 intestinal strains (205 isolated from inpatients and 143 from outpatients) recovered from fecal specimens. isolates were identified by using conventional physiological test ... | 2003 | 12820802 |
| geographical differences in bacteria detected in endodontic infections using polymerase chain reaction. | the polymerase chain reaction (pcr) is an innovative nucleic acid-based assay that has the highest sensitivity of any microbiological technique for the detection of bacteria. the purpose of this study was to use pcr to detect the presence of specific species of bacteria in samples collected from two geographical locations. microbial samples from abscesses of endodontic origin were collected from patients in portland, oregon, and rio de janeiro, brazil. pcrs with species-specific oligonucleotide ... | 2004 | 15055430 |
| 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 we evaluated the distribution of species and antimicrobial susceptibility among enterococcal isolates recovered from food obtained in retai ... | 2007 | 18060316 |
| emergence and characterisation of vanb vancomycin-resistant enterococcus faecalis in rio de janeiro, brazil. | here we describe the detection and characterisation of three isolates of vancomycin-resistant vanb-type enterococcus faecalis. sequence analysis suggested that these isolates harboured the vanb1 gene. the isolates were susceptible to the majority of antimicrobial agents tested, with the exception of chloramphenicol, erythromycin and vancomycin, and showed distinct profiles of high-level resistance to aminoglycosides. analysis of the clonal relatedness of the vanb e. faecalis isolates showed simi ... | 2012 | 22666871 |
