We compare the prevalence of H2O2--producing Lactobacillus species in women with or without bacterial vaginosis. H2O2--producing facultative Lactobacillus species were found in the vaginas of 37 (92.5%) of 40 normal women and 3 (4.1%) of 72 women with BV. Anaerobic Lactobacillus species (which do not produce H2O2) were isolated from 12 (16.6%) of 72 women with BV and 1 (2.5%) of 40 normal women. The production of H2O2 by Lactobacillus species may represent a nonspecific antimicrobial defence mechanism of the normal vaginal ecosystem.
我们比较了患有或未患有细菌性阴道病的女性中产生过氧化氢的乳酸杆菌种类的流行情况。在40名正常女性的阴道中，有37名（92.5%）发现了产过氧化氢的兼性乳酸杆菌种类，而在72名患有细菌性阴道病的女性中，只有3名（4.1%）发现了此类细菌。从72名患有细菌性阴道病的女性中分离出了厌氧乳酸杆菌种类（不产生过氧化氢），有12名（16.6%）；而在40名正常女性中，只有1名（2.5%）分离出此类细菌。乳酸杆菌产生过氧化氢可能代表了正常阴道生态系统的一种非特异性抗菌防御机制。
