Case Reports

Staphylococcus intermedius is a zoonotic coagulase-positive Staphylococcus that may be underreported by clinical microbiology laboratories. We present a case of S intermedius identified as a coagulase-negative Staphylococcus causing line-related bacteremia. The use of coagulase testing alone for identification of coagulase-positive Staphylococcus species may result in underreporting of S intermedius.
