Rapidly destructive Staphylococcus epidermidis endocarditis.

A 29-year-old man with rapidly destructive Staphylococcus epidermidis endocarditis after mitral valve reconstruction is presented. Resistance to rifampin and teicoplanin occurred during antibiotic treatment resulting in clinical failure and valve destruction. Subsequently, the patient was successfully treated, by combining valve replacement with antibiotic therapy including quinupristin/dalfopristin, levofloxacin, and vancomycin. In conclusion, S. epidermidis can cause rapid valve destruction with large vegetations, and combination of surgery and antibiotic therapy may be necessary.

Altered muropeptide composition in Staphylococcus aureus strains with an inactivated femA locus.

Tn551 inactivation of femA, a factor involved in methicillin resistance of Staphylococcus aureus, caused the production of peptidoglycan in which the fraction of monoglycyl- and serine-containing muropeptides was increased at the expense of pentaglycyl muropeptides. femA mutants have a specific block in the biosynthesis of pentaglycine cross bridges after the addition of the first glycine residue.
