Fifty-eight clinical strains of S. lugdunensis representing single patient isolates were used in this study. The strains were characterized with regard to putative fibrinogen binding and hemolysin genes and compared to their phenotypic correlates. Strains with a complete hemolysis were interpreted as positive (+). Strains producing no hemolysis (-) were compared to the negative control S. carnosus TM 300. Strains with a strong hemolysis after 48 h similar to that of S. aureus Cowan I were interpreted as producing strong hemolysis (++); + = positive; - = negative; (+) = weakly positive; ++ = strongly positive; ±* = test result indeterminate; pyrrolidonyl arylamidase (PYR); ornithine decarboxylase (ODC).
