  • Urine Culture with E. Coli: Meaning ... - New Health

    2021-7-29 · The presence of E. coli in urine usually indicates a urinary tract infection, but it may not always cause visible symptoms. When symptoms appear, they may include a burning sensation while urinating, a strong urge to urinate, passing small amounts of urine, passing strong-smelling urine, and urine that appears cloudy or red.

    E. coli were detected and quantified in artificial urine (obtained from Innovating Science™) with similar sensitivity to buffer; the LOD was also 12 CFU mL −1 in this matrix. Although the percent change in the R CT was slightly lower for detection of these bacteria in milk (216% change in the normalized R CT for 10 7 cells), a similar LOD and range of detection is maintained ( Fig. 3a ).
