RT Journal Article SR Electronic T1 Endocarditis caused by Staphylococcus warneri on a normal aortic valve following vasectomy JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 211 OP 213 VO 131 IS 3 A1 M. Dan A1 G. J. Marien A1 G. Goldsand YR 1984 UL http://www.cmaj.ca/content/131/3/211.abstract AB 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.
