B.I.—B. influenzæ. S.P.A.—Staphylococcus pyogenes aureus. M. pharyog—Micrococcus pharyngis siccus. Br.—Bronchus. Phago.—phagocytosis. Ht.-Heated blood agar. B. W.—B. welchii. Staphylococci develop opaque, paint-like colonies of varying size, with or without hemolysis, and so do other less frequently found bacteria give more or less distinctive colonies. The heated blood agar does not show these differences.
