Taxo™ P Discs are recommended for use in the presumptive identification of pneumococci, and are intended for use with pure cultures. Taxo™ P Discs are recommended for use in the presumptive identification of pneumococci, and are intended for use with pure cultures. 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.2 Taxo P Discs are impregnated with ethylhydrocupreine hydrochloride (optochin), a drug used for pneumonia therapy before sulfonamides became available.

The use of S. pneumoniae ATCC™ 6305 is recommended to demonstrate zone formation (14 mm or larger in diameter) and S. pyogenes ATCC 12384 is recommended for use as a negative (no zone) control. Quality control requirements must be performed is accordance with applicable local, state and/or federal regulations or accreditation requirements and your laboratory's standard Quality Control procedures. It is recommended that the user refer to pertinent NCCLS guidance and CLIA regulations for appropriate Quality Control practices. Taxo P Discs are 6 mm discs made from high quality absorbent paper impregnated with approximately 5.0 µg of ethylhydrocupreine hydrochloride per disc. The last disc in each cartridge is marked "X" and contains the agent as coded. For in vitro Diagnostic Use. Observe aseptic techniques and established precautions against microbiological hazards throughout all procedures. After use, test plates and other contaminated materials must be sterilized by autoclaving before discarding. | |||||||||
