Abstract Backgrounds The aim of this study was to confirm the propagation of various canine distemper viruses (CDV) in hamster cell lines of HmLu and BHK, since only a little is known about the possibility of propagation of CDV in rodent cells irrespective of their epidemiological importance.Methods The growth of CDV in hamster cell lines was camo iphone se case monitored by titration using Vero.dogSLAMtag (Vero-DST) cells that had been proven to be susceptible to almost all field isolates of CDV, with the preparations of cell-free and cell-associated virus from the cultures infected with recent Asian isolates of CDV (13 strains) and by observing the development of cytopathic effect (CPE) in infected cultures of hamster cell lines.Results Eleven of 13 strains grew in HmLu cells, and 12 of 13 strains grew in BHK cells with apparent CPE of cell royal nomadic 5413 rug fusion in the late stage of infection.

Two strains and a strain of Asia 1 group could not grow in HmLu cells and BHK cells, respectively.Conclusion The present study demonstrates at the first time that hamster cell lines can propagate the majority of Asian field isolates of CDV.The usage of two hamster cell lines suggested to be useful to characterize the field isolates biologically.
