Description:
Bowers and Jeffries1 have shown that there is complete correlation between bile-solubility and full `Optochin’ susceptibility for the differentiation of Streptococcus pneumoniae from other streptococci. Oxoid `Optochin’ Discs are paper discs ready impregnated with `Optochin’ (ethylhydrocuprein hydrochloride) which provide a convenient and reliable alternative to the bile-solubility test. Pneumococciare sensitive to `Optochin’ so that a culture shows a zone of inhibition around the impregnated disc, whilst streptococci either grow right up to the edge of the disc or, occasionally, show a very small zone of inhibition.
For the differentiation of Streptococcus pneumoniae.
