Used in microbiology laboratories for the selective isolation and detection of Cronobacter sakazakii (formerly Enterobacter sakazakii) from powdered infant formula and other clinical or environmental samples. The agar allows for easy differentiation of Cronobacter species based on distinct colony color—typically blue to blue-green—due to the chromogenic substrate. This enables rapid identification without the need for additional confirmatory tests in early screening. It is especially important in food safety and quality control settings where early detection of this pathogen is critical to prevent infections in neonates and infants. The medium suppresses the growth of non-target bacteria, improving specificity and reducing false positives.
