First report of a left ventricular assist device infection caused by Staphylococcus schleiferi subspecies coagulans: a coagulase-positive organism

Diagn Microbiol Infect Dis. 2012 Sep;74(1):68-9. doi: 10.1016/j.diagmicrobio.2012.05.027. Epub 2012 Jun 27.


Staphylococcus schleiferi subspecies coagulans is often misclassified as S. aureus given the production of a pseudocoagulase turning the tube coagulase test positive. It is therefore infrequently reported in the literature. We describe the first case of S. schleiferi subspecies coagulans left ventricular assist device infection in a patient awaiting heart transplantation.
