Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. Gram Stain Reaction. The Gram stain reaction, named after the Danish bacteriologist Hans Christian Gram, was originally devised in 1882.. Gram staining is based on the ability of the bacterial cell wall to retain the crystal violet dye. . Pharyngitis. Group 4. UPPER RESPIRATORY TRACT INFECTIONS. Rhinitis. Sinusitis.
