1.2.3 建立幽门螺杆菌感染AGS细胞模型:收集对数生长期的AGS细胞接种于6孔培养板中,按1 ×106个细胞/孔,每孔加1ml培养液。用PH7. 2的PBS 收集平板上的幽门螺杆菌,稀释菌液浓度至1 ×109CFU /ml。按照25:1、50:1、100:1、200:1的感染复数 (MOI,细菌数: 细胞数)加入幽门螺杆菌菌液到AGS细胞中,混合培...
The recipient 10-week-old male C57BL/6 mice were gavaged with 109 CFU of K.pn (W14 or TH1) or E.coli in 200 μL culture medium once every two days for 4 weeks. K.pn EVs (50 ng/mouse) by tail vein injection every 2 days for 4 weeks, then blood pressure was measured using ...
plantarum NJAU-01 at 107 CFU/g and 109 CFU/g significantly lowered the protein carbonyl content and protein surface hydrophobicity compared with the control (P < 0.05). The total sulfhydryl contents in L. plantarum NJAU-01 groups were significantly higher than that of the group without...
However, utilizing refrigerated storage, cell counts exceeded 7 log cfu/g for both free and immobilized cells, reaching populations greater than 109 cfu per share during the 10-day period, with no detectable spoilage. An investigation was conducted into the potential resistance of novel, fortified ...

For the probiotic group, a 0.2 mL solution containing 10 to the power of 8 colony-forming units (CFU) of LGG was administered orally each day until the animals were sacrificed. For radiation therapy (RT), a single 14 Gy dose was directed at the abdominopelvic area using a 6 mega-...
heating at approximately 37 °C. Finally, using a cell phone camera, we detect label-free drug-resistant bacteria as low as 104cfu/mL, which is higher than clinically required threshold (>105cfu/mL) by enhancing 1000 times of the limit of detection (LOD) of colorimetric nitrocefin assay. ...
We show that the limit of quantitation is 1.9×105 CFU/mL with this simple device, which is more than 10,000-times lower than is achieved with electrochemical impedance spectroscopy (EIS) and matrix-assisted laser desorption ionisation time-of-flight mass spectrometry (MALDI-ToF) on the same ...
