BORDET GENGOU AGAR BASE 500 grams/bottle

Bordet-Gengou Agar Base is used with the addition of horse blood for isolating Bordetella pertussis and other Bordetella species. The genus Bordetella consists of 4 species, all being respiratory pathogens: Bordetella pertussis, B. parapertussis, B. bronchiseptica and B. avium. Potato infusion and Proteose peptone provide nitrogen, vitamins, minerals and amino acids essential for growth. Glycerol provides carbon. Sodium chloride supplies essential electrolytes for transport and osmotic balance, and Bacteriological agar is the solidifying agent. The addition of blood provides extra growth nutrients for Bordetella species. Starch from the potato infusion absorbs fatty acids from nasal secretions on cotton swabs which inhibit growth of B. pertussis.
