Selective and differential agar would be the most helpful in isolating a specific pathogen from amongst a variety of normal microbiota, as it contains specific nutrients and chemicals that inhibit the growth of certain microorganisms while promoting the growth of others, allowing for the isolation and identification of the target pathogen. Nutrient agar and blood agar would not be selective enough to target a specific pathogen, while differential media would only be useful if the target pathogen had a specific metabolic characteristic that could be identified through a color change or other observable difference.
