OXOID
GVPC stands for Glycine–Vancomycin–Polymyxin B–Cycloheximide, the selective agents incorporated into the medium to inhibit the growth of non-Legionella organisms such as Gram-positive bacteria, Gram-negative bacilli, and fungi. The base of the medium is Buffered Charcoal Yeast Extract (BCYE) agar, which provides essential nutrients—such as L-cysteine and iron salts—required for Legionella growth. Activated charcoal in the formulation neutralizes toxic compounds that may interfere with bacterial recovery.
Typical Composition (per liter):
Appearance:
Application:
Used for selective isolation of Legionella spp. from water, air-conditioning systems, cooling towers, and respiratory clinical specimens. After inoculation, plates are incubated at 35–37 °C for 2–5 days in a humidified atmosphere containing 2.5–5% CO₂. Colonies of Legionella typically appear as gray-white to blue-green, glistening colonies with a ground-glass appearance.
Storage:
