Abstract
Although the introduction of automated blood culture systems has dramatically reduced laboratory personnel bench time, 48 to 72 h is still
required for the identification of pathogens such as methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus
(MSSA) and the accurate determination of antimicrobial sensitivities for prompt optimal patient therapy and infect
