Why is this included? when sCreening for beta stretoccoccci, some microbiology laboratoriesvser up a phenylethyl alcohol (PEA) agar plate, which contains ethanol but doesn't have blood, in addition to BAP. Why is this included?Explanation / Answer
Actually the media as mentioned in the Q Phenylethyl Alcohol agar is a kind of enriched media which is a selective medium for the isolation of gram-ve flora like streptococci. Actually, the concerned media known to restricts the growth of the concerned bacteria selectively and reversibly inhibits DNA synthesis and thus select for gram positives i.e. beta stretoccoccci.
BAP (i.e. Blood Agar Plate) is both differential and enriched medium. We know that the activity of the concerned bacteria to produce streptolysin which is known to lyse the RBCs with subsequent release of haemoglobin, therefore the concerned bacterium growing in the blood agar plate can be readily detected.
