Used as a selective and differential culture medium for the isolation and identification of Bordetella and Brucella species from clinical and environmental samples. Commonly employed in diagnostic laboratories to support the growth of fastidious organisms while inhibiting the growth of contaminating bacteria through the inclusion of antibiotics and other selective agents. Facilitates the detection of Bordetella pertussis and Bordetella parapertussis, the causative agents of whooping cough, in respiratory specimens. Also supports the cultivation of Brucella species, which are responsible for brucellosis in humans and animals. The medium provides essential nutrients and blood components that promote the growth of these slow-growing pathogens, enabling accurate diagnosis and epidemiological tracking.
