摘要
目的 监测在液体培养基中生长的溶脲脲原体 ( U u)细胞内微量 ATP的变化趋势 ,方法 运用生物化学发光技术 ,建立 ATP定量法。结果 Uu标准血清型 1( U1 )在孵育后的 3~ 12 h内其 ATP曲线呈活跃的上升趋势 ,且不受青霉素的影响 ,12 h后培养液内 ATP的总量已达到为 3.15 41× 10 - 1 1 mol,接近预期的标准。结论 U1 的 ATP曲线在质控范围内 ,培养 12小时后 ,其生长速度已接近对数生长期。因此 ,3~ 12小时这一时段适合观察抗生素对 Uu生长的影响 ,从而为体外客观而快速地进行
Developed a ATP micro-quantitative system based on bioluminescence,which can monitor the growth of broth-cultured ureaplasma urealyticum(Uu)indicated by ATP fluctuation The result showed that ATP curve of Uu standard serovar-1(U 1)ascended actively without the inhibition of penicillin during the 3~12 hours of incubation Comparison with the maximum ATP synthesis of Uu,3 1541×10 -11 mol ATP after 12 hours of U 1 culture suggests the exponential growth phase will coming. In conclusion,the 3~12 h ATP biolumine-scence system is well controllable,which is eminently suited for the observation of antibiotic influence on the Uu growth and further evaluation of thd Uu susceptibility in vitro
