The Thermo Scientific™ Oxoid™ Bacitracin Antimicrobial Susceptibility Discs are designed for manual antimicrobial susceptibility testing (AST) by the disc diffusion method. Each 6 mm paper disc is pre-impregnated with 10 units of bacitracin and is used to determine the in vitro sensitivity of bacteria, primarily Streptococcus pyogenes (Group A), to bacitracin.
The discs are housed in shatterproof spring-loaded cartridges for safe handling and precise placement. Each cartridge is individually sealed with a desiccant to maintain a moisture level of <2%, ensuring long-term stability and consistent performance.
These discs provide quantitative susceptibility data and allow visual assessment of microbial growth patterns and potential resistance mechanisms, making them ideal for routine use in clinical microbiology laboratories.
