Abstract

The susceptibility of Capnocytophaga ochracea, Eikenella corrodens, Eubacterium yurii, Fusobacterium nucleatum, Peptostreptococcus micros, Prevotella intermedia, Selenomonas sputigena, Wolinella recta to hypothiocyanite (OSCN-) produced by the lactoperoxidase system was tested. Results showed a decrease of bacterial survival rate after OSCN- exposure, with an intra- and inter-species variability from 0 to 95% for C. ochracea, 34-100% for E. corrodens, 0-83% for E. yurii, 1-15% for F. nucleatum, 8-61% for P. micros, 0-100% for P. intermedia, 0-44% for S. sputigena and 0-8% for W. recta. The survival rate did not correlate with the NADH/OSCN- oxidoreductase activity present in the lysed bacteria (r = -0.3248; N = 15; NS).

厌氧微生物对乳酸过氧化物酶产生的次硫氰酸盐的敏感性。

测定了赭绿脓毒杆菌、腐蚀艾肯氏菌、尤利真杆菌、核梭杆菌、微型胃链球菌、中间普雷沃氏菌、脓硒单胞菌、直Wolinella recta对乳酸过氧化物酶系统产生的下硫氰酸酯(OSCN-)的敏感性。结果表明，暴露于OSCN后，细菌存活率下降，其种内和种间变异率为0 ~ 95%，锈蚀菌为34 ~ 100%，玉氏菌为0 ~ 83%，核仁菌为1 ~ 15%，微孢子菌为8 ~ 61%，中间芽孢菌为0 ~ 100%，sputigena为0 ~ 44%，W. recta为0 ~ 8%。存活率与NADH/OSCN-氧化还原酶活性无关(r = -0.3248;N = 15;NS)。
