Centrifugation enhanced the infectivity of invasive Escherichia coli and Yersinia enterocolitica for HEp-2 cells. Noninvasive bacteria were not endocytosed after centrifugation. The centrifugation procedure may increase the sensitivity of testing for bacterial invasiveness in cell culture without causing false-positive results.
离心处理增强了侵袭性大肠杆菌和小肠结肠炎耶尔森菌对人喉表皮样癌细胞(HEp-2细胞)的感染性。离心处理后,非侵袭性细菌不会被内吞。离心操作可能会提高细胞培养中细菌侵袭性检测的灵敏度,且不会产生假阳性结果。
