AIM
To determine ability of lactobacilli strains indigenous for oral cavity of healthy persons to adhesion, autoaggregation, surface hydrophobicity, coaggregation and formation of biofilms.
MATERIALS AND METHODS
Twenty-three anatagonistically active isolates of lactobacilli, including 5 strains of Lactobacillus plantarum, 6--L. rhamnosus, 4--L. paracasei, and 8--L. fermentum, were studied. Characteristics of lactobacilli associated with adhesion, autoaggregation, surface hydrophobicity, coaggregation, and formation of biofilms were determined.
RESULTS
Bacteria were characterized by high and intermediate level of adhesion, autoaggregation, surface hydrophobicity, expressed ability to form biofilms and different coaggregation activity relative to test-strains Staphylococcus aureus, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, and Bacillus subtilis.
CONCLUSION
Studied characteristics of lactobacilli could be used for development of new probiotics aimed at stabilization of oral cavity normoflora.
目的
确定健康人口腔中的本土乳酸杆菌菌株的黏附、自聚集、表面疏水性、共聚集及生物膜形成能力。
材料与方法
研究了23株具有拮抗活性的乳酸杆菌分离株，包括5株植物乳杆菌、6株鼠李糖乳杆菌、4株副干酪乳杆菌和8株发酵乳杆菌。测定了与黏附、自聚集、表面疏水性、共聚集及生物膜形成相关的乳酸杆菌特性。
结果
这些细菌的特点是具有高和中等水平的黏附、自聚集、表面疏水性，表现出形成生物膜的能力，以及相对于测试菌株金黄色葡萄球菌、大肠杆菌、白色念珠菌、铜绿假单胞菌和枯草芽孢杆菌的不同共聚集活性。
结论
所研究的乳酸杆菌特性可用于开发旨在稳定口腔正常菌群的新型益生菌。
