Abstract
Summary
A partial pattern of dissociation into color-type and phase variation emerged after aging a strain of Staphylococcus. From the smooth yellow (aureus), a mucoid yellow and a rough yellow colony form were derived, and in addition a smooth white type (albus) and its mucoid white phase. Thus far the dissociative pattern is analogous with that of G. tetragena and Pneumococcus as regards type and phase variation and interconvertibility. It may apply to Staphylococcus in general.
