Final answer:
The specimen labeled 'pharyngeal pseudomembrane' should be inoculated on BAP, PEA, mannitol salt agars. Mannitol Salt Agar is a selective medium for staphylococci and other halotolerant bacteria, allowing determination of the bacterial growth characteristics and mannitol fermentation ability.
Step-by-step explanation:
The specimen labeled 'pharyngeal pseudomembrane' should be inoculated on options C. BAP, PEA, mannitol salt agars.
Mannitol Salt Agar (MSA) is a selective medium for staphylococci and other halotolerant bacteria. It contains a high concentration of salt to inhibit the growth of bacteria susceptible to osmotic stress. The medium also includes mannitol as a fermentable substrate, and phenol red as an indicator for acid. If the bacteria can ferment mannitol, there will be a color change from red to yellow in the medium.
Therefore, by inoculating the specimen on BAP (Blood Agar Plate), PEA (Phenylethyl Alcohol Agar), and MSA, you can determine the growth characteristics and mannitol fermentation ability of the bacteria in the pharyngeal pseudomembrane.
