Abstract
Serial passages of Echo 9 virus were carried out in 2 sets of monolayer tissue culture in Eagle's medium: (a) in primary monkey kidney (MK) cells (b) in monkey stable, (MS) kidney cells. After several passages, the virus lost most of its virulence for mice in MS cells but not in MK cells.Keywords
