Alpha haemolytic colonies were processed with optochin sensitivity and bile solubility test. If optochin test and bile solubility was positive, the organisms were identified as Pneumococci.
pneumoniae were subcultured and identified by using the optochin disk (Oxoid, Hampshire, UK) and bile solubility test. (14) All strains were stored at -80[degrees]C in 40% glycerol broth medium until further analysis.
For example, when the procedure manual states that a bile solubility test is used to differentiate Streptococcus pneumoniae from viridans streptococci in sputum cultures, the results of that test should be recorded on the worksheet.
