It is used to inhibit facultative gram-negative rods, preventing Enterobacteriaceae from overgrowing the anaerobes and inhibiting swarming of Proteus andClostridium septicum (6, 7). PEA agar is used for purulent specimens and when mixed infections are suspected (7). TABLE 1.
1 lis 2011 · Protocol (PDF) Phenylethyl alcohol (PEA) agar allows growth of gram-positive organisms, particularly cocci, while inhibiting most gram-negative bacteria and fungi. Specifically, PEA agar is a selective medium that is used for the isolation of gram-positive Staphylococcus species and Streptococcus species from clinical specimens or specimens ...
5 lip 2024 · Phenylethyl alcohol agar (PEA) is a specialized growth medium extensively used in microbiology. Its importance lies in its ability to selectively isolate certain types of bacteria while inhibiting others, which makes it a vital tool for clinical and research laboratories.
Phenylethyl alcohol agar (PEA) is a selective medium that permits the growth of gram-positive cocci while inhibiting most gram-negative organisms. PEA alters the membrane permeability, of Gram-negative bacteria allowing influx of otherwise blocked molecules.
Phenylethyl Alcohol Agar is a selective medium used for the isolation of gram-positive organisms such as Staphylococci and Streptococci. Phenylethyl alcohol exert inhibitory bacteriostatic action on gram-negative bacteria by inhibiting their DNA synthesis.
1 lis 2011 · A phenylethyl alcohol (PEA) agar plate inoculated with a mixture of gram-positive (Staphylococcus aureus) and gram-negative (Escherichia coli) bacteria. Only growth of the gram-positive bacteria is seen on the PEA agar. When inoculated on tryptic soy agar plates, both bacterial types show growth.
Remel Phenylethyl Alcohol Agar (PEA) is a solid medium recommended for use in qualitative procedures for selective isolation of gram- positive cocci. SUMMARY AND EXPLANATION
