Differentiation Disc BBL™ Taxo™ P Optochin 5.0 µg

Taxo P Discs are impregnated with ethylhydrocupreine hydrochloride (optochin)

The growth of pneumococci, but not of other streptococci, is markedly inhibited by this chemical

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 P Discs are 6 mm discs made from high quality absorbent paper impregnated with approximately 5.0 µg of ethylhydrocupreine hydrochloride per disc
