The research concerned the antagonistic activity of oral and pharyngeal bacterial flora in 44 children, of both sexes, aged 4-15. These properties were estimated basing upon in vitro inhibition of the growth of the standard indicator strains Staphylococcus aureus 209P and Escherichia coli K-12. Bacteria, both aerobic as well as anaerobic, inhibiting the growth of S. aureus 209P were found in every sample. The median percentages of bacteria showing these properties were not significantly different in both environments and they ranged from 25% to 33%. The antagonistic activity of oral and pharyngeal bacterial flora against the indicator strain E. coli K-12 was significantly lower when compared with the activity against the staphylococcal strain.
该研究关注了44名4至15岁男女儿童口腔和咽部细菌菌群的拮抗活性。这些特性是基于对标准指示菌株金黄色葡萄球菌209P和大肠杆菌K-12生长的体外抑制作用来评估的。在每个样本中都发现了抑制金黄色葡萄球菌209P生长的需氧菌和厌氧菌。在两种环境中显示这些特性的细菌的中位数百分比没有显著差异，范围在25%至33%之间。与对葡萄球菌菌株的活性相比，口腔和咽部细菌菌群对指示菌株大肠杆菌K-12的拮抗活性显著较低。
