title: Engineered BGMK cells for sensitive and rapid detection of enteroviruses.
abstract: Decay-accelerating factor (DAF) has been reported to be a cellular receptor for several enteroviruses. Buffalo green monkey kidney (BGMK) cells expressing human DAF (BGMK-hDAF cells) showed increased susceptibility and sensitivity to several types of enteroviruses compared to wild-type BGMK cells. When 17 frozen positive clinical samples were tested, BGMK cells detected 8 and BGMK-hDAF cells detected 16. Since the CaCo-2 cell line has been documented to support the replication of most enteroviruses, CaCo-2 cells were mixed with BGMK-hDAF cells in order to increase the number of viruses detected. Thirty-four frozen clinical samples that previously had tested positive for enteroviruses were tested, and the following numbers were detected: 33 of 34 by CaCo-2/BGMK-hDAF cells, 29 of 34 by CaCo-2/BGMK cells, 28 of 34 by H292/RD (E-mix A) and A-549/BGMK (E-mix B) cells, and 26 of 34 by MRC-5 and pRhMK cells.
