I read the 'Manual of Clinical Microbiology', published by ASM, a while ago,
but I seem to remember that coagulase negative Staphs can take even weeks to
grow particularly from prosthetic heart valves. We sign out our negative
cultures in 3 days but hold the broth cultures for 7 days, screening them daily
for growth before we discard them. We hold blood cultures for 5 days before
reporting them as negative. For more information, I suggest you read the
chapter on Staph in the 'Manual of Clinical Microbiology'.
