BD Identification

Blank Discs, 1/4" diam. S&S-470

Taxo A discs are impregnated with a low level of bacitracin. According to the work of Maxted, of Levinson and Frank, and others, the group A streptococci may be differentiated from the other Lancefield groups of hemolytic streptococci by the formation of a zone of inhibition around the disc.

Taxo P Discs are impregnated with ethylhydrocupreine hydrochloride (optochin), a drug used for pneumonia therapy before sulfonamides became available. The growth of pneumococci, but not of other streptococci, is markedly inhibited by this chemical.^1,2 Pneumococci may, therefore, be differentiated from other alpha-hemolytic streptococci by the formation of a zone of inhibition around a Taxo P disc placed on a blood agar plate heavily inoculated with a pure culture suspected to be Streptococcus pneumoniae.

Taxo™ ONPG Discs are used for the detection of lactose fermenters, especially those that do not promptly ferment lactose in some routine identification media such as Triple Sugar Iron Agar (TSI Agar) or Kligler Iron Agar.

These discs are used for semi-quantitative in vitro susceptibility testing by the agar disc diffusion test procedure of common, rapidly growing and certain fastidious bacterial pathogens. These include the Enterobacteriaceae, Staphylococcus spp., Pseudomonas spp., Acinetobacter spp., Enterococcus spp., Vibrio cholerae and, by modified procedures, Haemophilus influenzae, Neisseria gonorrhoeae, Streptococcus pneumoniae and other streptococci. NOTE: Special procedures are required for testing pneumococci, enterococci and methicillin/oxacillin-resistant staphylococci, for performing ß-lactamase tests and for screening and confirmatory tests for ESBLs; see the “RESULTS” section.
