Table 1. Inactivation of bacteria by FdCa (OH)₂ in feces during their recovery by PBS, within min.

Concentration of FdCa (OH)2	RFa)
	E. coli	S. Infantis
5%	≥4.59 ± 0.00b)	≥4.53 ± 0.00
10%	≥4.59 ± 0.00b)	≥4.53 ± 0.00
20%	≥4.59 ± 0.00b	≥4.53 ± 0.00

Chicken feces were inoculated with bacteria in conical centrifuge tubes, and then, different amounts of FdCa (OH)₂ powder was added on them and mixed properly, and soon thereafter, the remaining bacteria were harvested by adding 10 ml PBS. a) Reduction factor=log₁₀ (titer of control/ml) −log₁₀ (titer of treated samples/ml). b) Data represent mean ± standard deviation of three individual reactions.
