Alkali Scientific Columbia CNA Agar, 500 Grams
Supplier: Alkali Scientific OLU001CP
Columbia CNA Agar is a selective medium used for the isolation and identification of Gram-positive bacteria, particularly those in the genus Streptococcus. The medium contains colistin and nalidixic acid, which inhibit the growth of Gram-negative bacteria while supporting the growth of Gram-positive organisms. Columbia CNA Agar is enriched with blood, allowing for the observation of hemolytic reactions, such as alpha, beta, and gamma hemolysis. This medium is commonly used in clinical microbiology labs for the isolation of pathogens from clinical specimens and for differentiating bacteria based on their hemolytic properties.
