... Coagulase-negative Staphylococci were considered as contaminants of bacterial cultures. However, this group especially S. epidermidis has emerged as an important pathogen and a major cause of serious ... See full document

... The data demonstrate that patients enter the hospital colonized with slime-producing strains of coagulase-negative staphylococci and that during hospitalization the staphylococcal skin b[r] ... See full document

... Coagulase-negative staphylococci (CNS) are important causes of infective endocarditis (IE), but their microbiological profiles are poorly described. We performed DNA target sequencing and ... See full document

... Unlike prior studies, where ST2 was predominant among linezolid-resistant S. epidermidis strains (27), 42% of the linezolid- resistant S. epidermidis isolates investigated herein were ST23, and no isolates were ST2 ... See full document
