Taxo A Bacitracin Disc. 10 Cartridges (10/pk)

Used for the presumptive identification of group A beta-hemolytic streptococci. Contains 50 discs. Must be stored at -20°C to +8°C. Shelf life: 548 Days . The BD Taxo A Bacitracin Disc is used for the presumptive identification of group A beta-hemolytic streptococci after overnight incubation. Group A beta-hemolytic streptococci are sensitive to small amounts of bacitracin while beta-hemolytic streptococci of other serologic groups are more resistant. Therefore, if a zone of inhibition forms around the Taxo A disc, the organism is a presumptive group A streptococcus. Please note that the BD Taxo A Bacitracin Disc is for presumptive testing and results should be followed with more specific physiological and/or serological tests. Each disc is impregnated with approximately 0.04 units of bacitracin. Configuration Options.
