Product Summary and Explanation
Ellner et al. described Columbia CNA Agar as a variation of Columbia Blood Agar Base that is selective for Gram-positive cocci. Colistin and Nalidixic Acid are added to the formula, selecting for Gram-positive organisms and fungi by suppressing Gram-negative bacteria. Columbia CNA Agar is used as a primary plating medium for urine cultures.
