Abstract
Korman, RuthZ. (Cornell University, Ithaca, N.Y.). Coagulase-negative mutants ofStaphylococcus aureus: genetic studies. J. Bacteriol.86:363–369. 1963.—The behavior in mutation and transduction of pleiotropic coagulase-negative mutants ofStaphylococcus aureusPS 53 (NCTC 8511) was analyzed. Coagulase-positive colonies were recovered, as well as a novel phenotype resistant to some cell-wall inhibitors and differing in sugar fermentation pattern. The hypothesis that the coagulase-negative strains differ from the original propagating strain in the structure or organization of the cell wall is discussed.
