novel 10-bp deletion in the translational attenuator of a constitutively expressed erm(a) gene from staphylococcus epidermidis.	alterations in the erm(a) regulatory region of six clinical isolates of staphylococcus epidermidis and one of staphylococcus haemolyticus displaying a constitutive resistance phenotype were investigated. anovel deletion of 10 bp with respect to the corresponding sequence of tn554 was identified in the attenuator of a constitutively expressed erm(a) gene of one of the s. epidermidis isolates. thus far, this is the smallest deletion conferring constitutive resistance in the translational attenuato ...	2007	17661294
differentiation of staphylococcus spp. by terminal-restriction fragment length polymorphism analysis of glyceraldehyde-3-phosphate dehydrogenase-encoding gene.	classical phenotypic and biochemical testing do not lead to correct identification of the distinct staphylococcus species. therefore, the aim of our study was to develop a method for the reliable and accurate determination of distinct staphylococcus species. in the present study, the 931-934-bp partial sequences of the glyceraldehyde-3-phosphate dehydrogenase-encoding (gap) gene of 28 validly described staphylococcus species were amplified and sequenced. by using the respective sequence informat ...	2007	17681623
in vitro activity of daptomycin and tigecycline against coagulase-negative staphylococcus blood isolates from bone marrow transplant recipients.	multi-resistant coagulase-negative staphylococci (cns) may cause systemic infections in patients undergoing bone marrow transplantation. daptomycin, a new lipopeptide, and tigecycline, a new glycylcycline, have excellent activity against gram-positive bacteria including methicillin-resistant staphylococci. this study presents the in vitro activity of daptomycin and tigecycline compared to vancomycin and fosfomycin against 105 cns isolated from 76 bone marrow transplant patients with symptomatic ...	2007	17714506
persistent strains of coagulase-negative staphylococci in a neonatal intensive care unit: virulence factors and invasiveness.	coagulase-negative staphylococci (cons) are the major cause of nosocomial bacteraemia in neonates. the aim of this study was to investigate whether persistent strains of cons possess specific bacterial characteristics as compared with sporadic non-cluster isolates. in total, 180 blood culture isolates (95 contaminants and 85 invasive isolates) obtained from a single neonatal unit over a 12-year period were studied. pulsed-field gel electrophoresis (pfge) identified 87 persistent cons strains (en ...	2007	17850346
evolution of slime production by coagulase-negative staphylococci and enterotoxigenic characteristics of staphylococcus aureus strains isolated from various human clinical specimens.	the present study was designed to determine the slime production of coagulase-negative staphylococci (cons) and the enterotoxigenic properties of staphylococcus aureus strains, and to evaluate the clinical importance of slime-producing cons and enterotoxigenic s. aureus strains isolated from various human clinical specimens. for this purpose, a total of 120 staphylococcus strains were isolated and identified, and further characterized for their slime production and enterotoxigenicity. of the cli ...	2007	17893164
distribution of staphylococcal cassette chromosome mec (sccmec) types i, ii, iii and iv in coagulase-negative staphylococci from patients attending a tertiary hospital in southern brazil.	coagulase-negative staphylococci (cons) are now recognized as the aetiological agents of an important range of infections in humans. most developed countries have reported an increase in cons infections in hospitalized patients that are resistant to meticillin and other antibiotics. staphylococcal cassette chromosome mec (sccmec) typing is essential for understanding the molecular epidemiology of meticillin-resistant staphylococcus strains. sccmec elements are currently classified into types i t ...	2007	17893169
development of a real-time pcr assay for the detection and identification of staphylococcus capitis, staphylococcus haemolyticus and staphylococcus warneri.	staphylococcus capitis, staphylococcus haemolyticus and staphylococcus warneri are coagulase-negative staphylococci. each species has different characteristics, and a difference in pathology is also seen in compromised hosts. therefore, the development of a species-specific simple detection method for the identification of these staphylococci is important. here, a species-specific real-time pcr assay is reported that targets the superoxide dismutase a-encoding gene of these bacteria. primers wer ...	2007	17893172
