Namaste sir,
Is Burkholderia cepacia grow on Nutrient agar?
Yes. Burkholderia cepacia is not fastidious and can grow on basic, non-selective media like Nutrient agar.
Burkholderia cepacia is a Gram-negative, non-spore-forming, rod-shaped bacterium known for its ability to survive in a variety of environments. Unlike fastidious bacteria that require specialized growth media or specific nutrients, B. cepacia typically can grow on simple, general-purpose media. Nutrient agar, which provides basic nutrients such as peptones and beef extract, is usually sufficient to support its growth.
When cultured on Nutrient agar, B. cepacia typically produces smooth, circular colonies. They may have a characteristic yellowish or greenish pigment. The bacteriumโs ability to thrive under relatively minimal nutritional conditions is one of the reasons itโs found widely in soil, water, and occasionally in hospital environments, posing risks to immunocompromised patients, especially those with cystic fibrosis.
