We attempted to find the possibility of determining the minimum inhibitory concentration and minimum bactericidal concentration needed for nano-silver base inorganic anti-microbial agent (Novaron(®) AG 300, AG 1100) against Streptococcus mutans in vitro using broth dilution assay.
An ampoule of freeze-dried S. mutans NCTC reference strain was revived, and the colony-forming units (CFU) were calculated. The MIC and MBC was determined by broth dilution assay using different concentrations of Novaron(®) AG 300 and Novaron(®) AG 1100 against 1 × 10(5) CFU/ml of S. mutans.
The MIC and MBC of Novaron(®) AG 300 and Novaron(®) AG 1100 against S. mutans were found to be 40 μg/ml.
Novaron(®) has anti-bacterial effect against S. mutans. Further studies are needed to explore the applicability of these silver-supported anti- microbial agents in clinical dentistry.
我们试图通过肉汤稀释法,找出测定纳米银基无机抗菌剂(诺瓦龙(®)AG 300、AG 1100)对变形链球菌的体外最低抑菌浓度和最低杀菌浓度的可能性。
复苏一支冻干的变形链球菌NCTC参考菌株安瓿,计算菌落形成单位(CFU)。采用肉汤稀释法,使用不同浓度的诺瓦龙(®)AG 300和诺瓦龙(®)AG 1100,针对1×10⁵CFU/ml的变形链球菌测定最低抑菌浓度(MIC)和最低杀菌浓度(MBC)。
发现诺瓦龙(®)AG 300和诺瓦龙(®)AG 1100对变形链球菌的最低抑菌浓度和最低杀菌浓度均为40μg/ml。
诺瓦龙(®)对变形链球菌有抗菌作用。需要进一步研究以探索这些载银抗菌剂在临床牙科中的适用性。
