Test microorganisms used according to usp 51 test are Staphylococcus aureus, E.coli, Ps.aeruginosa, Candida albicans and Aspergillus brasiliensis (Aspergillus niger).Additional test organisms can also be tested.

Surviving microorganism are counted at 7, 14 and 28 days of the challenge using standard microbiology microorganisms counting techniques. Test microorganisms count and log reduction is calculated at each time interval (7, 14 and 28 days).
