Bacterial colony morphologies and identification. (a) We observed a variety of colonies on the agar plates and classified the colonies into four major colony forms, morphologically. Representative bacteria composed of each colony were visualized with their Gram-stain images. (b) Major colony forms, identified bacteria, and frequencies (incidence and % total). (c) Identified bacteria, their localization, and pathogenicity in humans.
