Columbia Agar is used with or without blood for the isolation and cultivation of a wide variety of fastidious microorganisms. Supplementation with blood (5 - 10%) provides additional growth factors for fastidious microorganisms, and aids in determining hemolytic reactions. Hemolytic patterns may vary with the source of animal blood and the type of basal medium used. In general, blood agar bases are relatively free of reducing sugars, which have been reported to adversely influence the hemolytic reactions of -hemolytic streptococci. Columbia Agar is a nutritiously rich general purpose medium This medium contains a mixture of peptones, which provides a blend of nitrogenous compounds and amino acids to enhance growth. Columbia Agar can be supplemented with 5 - 10% sheep, rabbit, or horse blood for use in isolating, cultivating, and determining hemolytic reactions of fastidious pathogenic microorganisms. The addition of antibiotics, kanamycin or gentamicin, to Columbia Agar suppresses the growth of certain Gram-negative and Gram-positive microorganisms. Columbia Agar can provide an anaerobic environment when supplemented with growth factors, hemin, vitamin K1, and sheep blood.
