MAST Colistin Sulphate 25µg Antibiotic Test Discs – 5 × 50 Discs

MAST Colistin Sulphate 25µg Antibiotic Test Discs are antibiotic-impregnated paper discs designed for specialized microbiology research and non-clinical laboratory investigations involving Colistin Sulphate. Each disc contains 25 micrograms of Colistin Sulphate, a polymyxin-class antibacterial agent that acts primarily by disrupting the outer cell membrane of susceptible Gram-negative bacteria. Colistin is particularly relevant to microbiological research involving multidrug-resistant Gram-negative organisms, including selected Pseudomonas aeruginosa, Acinetobacter baumannii and Enterobacterales isolates. Manufactured by MAST Group, these discs provide standardized antibiotic content in convenient dispensing cartridges for appropriate laboratory research procedures. Important: Colistin disc diffusion cannot reliably establish clinical susceptibility or resistance. For clinical testing, validated broth microdilution methods should be used instead.
