【摘要】 目的探索草绿色链球菌Ａ１９抑制脑膜炎双球菌生长的机理。方法采用半定量接种， 活菌与死菌不同生长阶段的草绿色链球菌Ａ１９抑菌效果比较的方法。结果抑制作用由草绿色 链球菌Ａ１９的代谢产物引起，且稳定持久。结论揭示从草绿色链球菌Ａ１９的代谢产物中提取抑 菌成分的可能性。更多还原

【Abstract】 Objective To explore the mechanism for streptococcus viridans A19’s inhibiting the growth of neisseria menigitidis A19. Methods Incubacted living or dead streptococcus viridans A19 by semi-qualtity, specific analysis effection of anti-bacteria in the different growth stages. Result The inhibitory activity was caused by metabolite of streptococcus viridans A19 and was stable. Conclusion it was proposed that a chemical substance could be extracted from the metabolite and used in clinical practice.更多还原
