Phenylethyl Alcohol Agar (PEA Agar) with 5% Sheep Blood is a selective and differential medium used for the isolation of Gram-positive organisms, particularly cocci such as Staphylococcus and Streptococcus species, from clinical or mixed flora specimens. It is especially effective in inhibiting the growth of Gram-negative bacilli, including Proteus and Pseudomonas, which can overgrow cultures and obscure diagnostic findings.
The presence of phenylethyl alcohol disrupts DNA synthesis in Gram-negative bacteria by altering membrane permeability, thus selectively suppressing their growth. The addition of 5% defibrinated sheep blood enhances the medium by enabling detection of hemolytic activity, allowing for the differentiation of hemolytic patterns among Gram-positive cocci.
Each plate is pre-poured with 20mL of sterile agar, ensuring optimal depth and surface area for streaking and incubation. These plates are widely used in diagnostic laboratories, hospitals, and microbiology research facilities for
- Selective for Gram-positive organisms, especially cocci
- Phenylethyl alcohol suppresses Gram-negative bacterial overgrowth
- 5% sheep blood enables hemolysis pattern identification
- 20mL fill ensures consistent growth and incubation conditions
- Supplied in packs of 10 plates for routine lab workflows
- Ideal for clinical diagnostics, specimen screening, and pathogen differentiation
PEA Agar with Sheep Blood is a trusted tool in clinical microbiology, enabling clearer, more accurate isolation of clinically significant Gram-positive bacteria from complex specimens.
