| Abstract: | Endocarditis caused by Staphylococcus warneri and necessitating valve replacement occurred in a previously healthy 32-year-old patient following vasectomy. No sign of an underlying valvular defect was noted during the operation. S. warneri is a recently identified species of coagulase-negative staphylococci. Endocarditis caused by coagulase-negative staphylococci is uncommon in young, healthy patients with normal heart valves and has not previously been described as a complication of vasectomy. Similarly, infections caused by S. warneri have not previously been described in humans. |
