Reduction index (R)
T5/HA 0.34 * 0.38 * 0.04 1.73 0.08
T-S/HA 0.14 * 0.25 * 1.28 1.90 0.25
TNF6C/HA 0.43 * 0.37 * 0.06 0.18 * 0.05

Biocidal activity of specimen is observed when R ≥ 2 (>99%). R = Ut – At, where Ut is the common logarithm of the number of bacteria in the untreated microbial suspension and At is the common logarithm of the number of bacteria in the treated microbial suspension. * no significant increase in microbial growth (<10%).
