Microorganisms in dental plaque live in constant association with saliva. The role of saliva in the adherence of bacteria to the teeth and the antibacterial properties of saliva have been well investigated; less interest has been shown in the possible role of saliva as a substrate for oral microorganisms. In this study it was shown that saliva can serve as a growth medium for oral Streptococcus spp. and Actinomyces viscosus. The cell production of these organisms on saliva was carbohydrate limited. The doubling times for growth on glucose-supplemented saliva (4 to 5 mmol/liter) ranged from 1.6 to 4.0 h. The availability of carbohydrate sources for the oral microflora is discussed in relation to microbial growth in the oral cavity.
牙菌斑中的微生物一直与唾液密切相关。唾液在细菌黏附于牙齿方面的作用以及唾液的抗菌特性已得到充分研究;而对于唾液作为口腔微生物底物的潜在作用,人们的关注较少。本研究表明,唾液可作为口腔链球菌属和黏性放线菌的生长培养基。这些微生物在唾液上的细胞增殖受碳水化合物限制。在补充葡萄糖的唾液(4至5毫摩尔/升)上生长的倍增时间为1.6至4.0小时。本文结合口腔微生物在口腔中的生长情况,讨论了口腔微生物碳水化合物来源的可利用性。
