Columbia Broth (Powder)

Formulated to enhance recovery of aerobic and anaerobic organisms from blood cultures. Eller et al. first described Columbia Broth. It was designed to produce rapid and luxuriant growth of a range of organisms due to its high nutrient content. It contains meat peptone, casein peptone and yeast extract all of which are highly nutritious components. The meat peptone contains sufficient sulfonamide antagonists to prevent sulfonamide inhibition of growth. Columbia Broth, in the presence of CO2 and supplemented with SPS, is an excellent blood culture medium. , Microbiological Analysis:, Bacteroides fragilis ATCC 25285: Good, Escherichia coli ATCC 25922: Good, Neisseria meningitides ATCC 13090: Good, Pseudomonas aeruginosa ATCC 27853: Good, Streptococcus pneumonia ATCC 6305: Good, Streptococcus pyogenes ATCC 19615: Good, Appearance: Beige, homogeneous, free flowing powder.
