From: Propagation of Asian isolates of canine distemper virus (CDV) in hamster cell lines
Growth profiles of CDV strains of Ond and 007Lm in HmLu cells. Viruses were harvested at every passage as cell-free viruses of Ondestepoort (open circle), or 007Lm (open diamond) and cell-associated viruses of Ondestepoort (black circle), or 007Lm (black diamond) and were titrated on Vero-DST cells as described in Materials and Methods. The obtained virus titers (PFU/ml) were plotted against passages number.
