This current study was conducted to compare four cell lines for their yield of C. burnetii. Four different isolates of C. burnetii (Henzerling, Arandale, Cumberland and Timony) were grown in DH82, L929, Vero and XTC-2 cell lines. The DH82 and XTC-2 cells lines produced the highest C. burnetii yield which was slightly less than the yields achieved in recently published studies using cell free media. The Arandale isolate of C. burnetii produced a significantly higher yield in DH82 cells compared to XTC-2 cells (P 0.03).展开更多
