Test your understanding of Baird Parker Agar, a selective medium used for isolating Staphylococcus aureus. This mock exam covers key concepts including agar composition, colony morphology, and diagnostic applications. Try these questions to assess your microbiology knowledge!
The medium contains lithium chloride and tellurite to inhibit most bacteria except staphylococci, while egg yolk emulsion helps differentiate S. aureus (black colonies with halo) from S. epidermidis (black colonies without halo). Can you identify which organisms grow on Baird Parker Agar? E. coli is typically inhibited, whereas Staphylococcus species produce characteristic colonies. Commercial brands like HiMedia, Oxoid, and Merck supply this agar with slight variations in formulation.
How well do you know the principle and preparation of Baird Parker Agar? The base contains peptones, glycine, and pyruvate, supplemented with egg yolk tellurite after autoclaving. Incubation at 35–37°C for 24–48 hours allows optimal growth. Is this medium selective, differential, or both? Test yourself further with more questions on colony identification, uses in food microbiology, and common laboratory protocols related to this essential diagnostic tool.
