Lead the defense against multi-drug resistant pathogens with CHROMagar™ COL-APSE. Engineered as an advanced, highly sensitive selective chromogenic culture medium, this formulation is designed for the qualitative direct detection and presumptive differentiation of colistin-resistant (COL-R) Gram-negative bacteria. Whether screening for plasmid-mediated resistance (mcr genes) or chromosomal mutations, this powerful tool allows labs to isolate, count, and differentiate critical superbugs directly from mixed flora within 18–24 hours.
