Bile solubility Test Strip  

Description:

The test is used as a presumptive identification test for S. pneumonia. Sodium deoxycholate is a surface-active bile salt. It acts upon the cell wall of pneumococci, resulting in cell lysis. The test is performed with alpha-hemolytic streptococcal colonies. Oxgall is dehydrated bile that can be used, but sodium deoxycholate is preferred.  It can be used together with other test products flexibly.  

Directions:

Step1 Each Bile Solubility test strip for one colonyunder test.

Step2 Drop a few bile salt solution into one tube, add the same amount of sterile physiological saline to other tube.

Step3 Incubate at 35°C for 15-20 minutes.

Step4 Observe for appearance of becoming clear or fall of turbidity.
