静磁场对犬型钩端螺旋体生长及细胞分裂的影响
Effects of Static Magnetic Field on Growth of Leptospire, Leptospira interrogans serovar canicola: Immunoreactivity and Cell Division
摘要：
研究了暴露于恒定磁场（永磁铁氧体磁体的磁通量密度= 140 mT）的细菌犬型钩端螺旋体的影响。钩端螺旋体细胞暴露于该领域后的变化，确定其生长行为和凝集免疫反应性的变化的基础上，使用暗视野显微镜与视觉成像的同源抗血清。结果表明，暴露组钩端螺旋体细胞密度和凝集反应性均低于对照组。有趣的是，一些暴露的钩端螺旋体细胞显示出异常的形态，如大的长度。我们讨论了这些观察结果的一些可能原因。
英文摘要：
The effects of the exposure of the bacterium, Leptospira interrogans serovar canicola to a constant magnetic field with magnetic flux density from a permanent ferrite magnet = 140 mT were studied. Changes in Leptospira cells after their exposure to the field were determined on the basis of changes in their growth behavior and agglutination immunoreactivity with a homologous antiserum using darkfield microscopy together with visual imaging. The data showed that the exposed Leptospira cells have lower densities and lower agglutination immunoreactivity than the unexposed control group. Interestingly, some of the exposed Leptospira cells showed abnormal morphologies such as large lengths. We discussed some of the possible reasons for these observations.
