CATC Agar is widely used in microbiology for the selective isolation and cultivation of anaerobic bacteria, particularly from clinical specimens. It supports the growth of fastidious organisms while inhibiting contaminants through selective agents. The medium is especially useful in diagnosing infections involving anaerobes, such as those from abscesses, wounds, and respiratory or gastrointestinal sources. Its formulation enhances colony morphology and facilitates easier identification. CATC Agar is often employed in research and diagnostic labs where reliable anaerobic culture conditions are required.
