Jan 5, 2022 · Blood agar is an enriched nutritious medium that supports the growth of fastidious organisms by supplementing it with blood or as a general medium without the blood. The blood added to the base provides more nutrition to the medium by providing additional growth factors required for these fastidious organisms.

Aug 10, 2022 · Blood Agar (BA) are enriched medium used to culture those bacteria or microbes that do not grow easily. Such bacteria are called “fastidious” as they demand a special, enriched nutritional environment as compared to the routine bacteria.

Blood agar consists of a base containing a protein source (e.g. tryptones), soybean protein digest, sodium chloride (NaCl), agar, and 5% sheep blood. Blood contains inhibitors for certain bacteria such as Neisseria and Haemophilus genera, so the blood agar must be heated to inactivate these inhibitors and to release essential growth factors (e ...
