Differentiate between bile soluble Streptococcus pneumoniae and other insoluble alpha-hemolytic streptococci using Thermo Scientific™ Remel™ BactiDrop™ Desoxycholate (10%). In 1900, Neufeld used a bile salt sodium desoxycholate to detect autolysis, that differentiated bile-soluble S. pneumoniae from bile-insoluble alpha-hemolytic streptococci1. Evans employed 10% bile to lyse broth cultures of pneumococci2. Hawn and Beebe evaluated the effectiveness of applying bile salts directly to a blood agar plate culture of pneumococci3.
