This study was intended to investigate the effectiveness of static magnetic field on the growth of Escherichia coli () provided from two sources, the urine samples of patients with urinary tract infections and the reference strain ATCC 25922. Bacterial samples in Nutrient Broth were subjected to a range of magnetic intensities (2, 4, 6, 9, 14, 16, 18, and 20 mT) at various exposure times (0, 15, 30, 45, 60, 75, and 90 min). The survival rate was measured in the presence and absence of the magnetic field over time. The cell counts of uropathogenic did not statistically differed from those of the standard strain if exposed to the magnetic field. The fluctuation was observed in cell viabilities at different magnetic intensities below 18 mT. Both groups presented a significant decline in survival rate as exposed to 18 and 20 mT.
本研究旨在调查静磁场对来自两个来源的大肠杆菌（）生长的有效性，这两个来源分别是尿路感染患者的尿液样本和参考菌株ATCC 25922。将营养肉汤中的细菌样本在不同暴露时间（0、15、30、45、60、75和90分钟）下置于一系列磁场强度（2、4、6、9、14、16、18和20毫特斯拉）中。随着时间的推移，在有和没有磁场的情况下测量存活率。如果暴露于磁场中，尿路致病性大肠杆菌的细胞计数与标准菌株的细胞计数在统计学上没有差异。在低于18毫特斯拉的不同磁场强度下观察到细胞活力的波动。当暴露于18和20毫特斯拉时，两组的存活率均显著下降。
