GVPC Agar – selective medium for the enumeration and confirmation of Legionella spp. and Legionella pneumophila in water

Bio-Rad GVPC agar is a selective medium for the enumeration and confirmation of Legionella spp. and Legionella pneumophila in water: water intended for human consumption, hot water for sanitation purposes, water for industrial use, natural mineral water for thermal purposes, water for recreational activities. The principle of the medium relies on the ability of Legionella to multiply on buffered agar containing yeast extract, activated charcoal, L-cysteine, alpha-ketoglutarate and iron. Legionella form grey-blue colonies varying sometimes to yellow, green, white, brown, purple and pink. Due to the presence of cycloheximide, this medium inhibits yeast Vancomycin and polymyxin inhibit the growth of Gram-negative bacteria and the majority of Gram-positive. The medium is available as ready-to-use plates.
