Y. Naito et al., BACTERICIDAL EFFECT OF RAT CYSTATIN-S ON AN ORAL BACTERIUM PORPHYROMONAS-GINGIVALIS, Comparative biochemistry and physiology. Part C, Pharmacology toxicology & endocrinology, 110(1), 1995, pp. 71-75
We tested antibacterial and antiviral activities of rat cystatin S, a
cysteine proteinase inhibitor, belonging to the family 2 cystatins aga
inst 18 different bacterial species and poliovirus type 1 (Sabin). Rat
cystatin S specifically inhibited the growth of a human oral anaerobi
c bacterium Porphyromonas gingivalis due to a bactericidal effect.
