Abstract

Only a limited number of disinfectants are capable of inactivating coccidia oocysts, and in Japan, ortho-phenylphenol-based disinfectants (a combination of cresol and 1,2-dichlorobenzene) are mainly used. However, resistance of oocysts to ortho disinfectants has been reported. Previously, we demonstrated a synergistic enhancement of microbicidal activity by adding food-additive-grade calcium hydroxide with a mean particle size of 10 µm to a quaternary ammonium compound. In the present study, we found that the addition of calcium hydroxide and a quaternary ammonium compound to the ortho disinfectant synergistically and significantly enhanced its oocysticidal effect.
