Clinical significance of coagulase-negative staphylococci isolates from nosocomial bloodstream infections.

Background: Identification of coagulase-negative staphylococci (CoNS) as nosocomial pathogens or contaminants is significant for microbiologists and clinicians. This study aimed to determine the frequency of isolation and antimicrobial resistance patterns of CoNS isolates from nosocomial bloodstream infections (BSIs) and to identify risk factors associated with true bacteremia caused by these emerging pathogens in a Saudi tertiary care hospital.

Methods: All CoNS-positive cultures from inpatients were identified using the standard methods during a 10-month period.
