Canine bladder epithelial cells in culture: susceptibility to canine distemper and measles viruses

A canine bladder epithelial cell strain was established in culture for the study of canine distemper virus. Epithelial cells were scraped off the bladder with a scalpel and were cultured in enriched Eagle's medium. Cells were enzymatically dispersed and passed over 46 population doublings which covered a period of more than 3 years. The cells were heteroploid when karyotyped at passage level 5 and 42. This cell strain permitted direct isolation of canine distemper virus and also showed susceptibility to laboratory strains of measles virus. Seemingly, establishment of cell strains from canine bladder epithelium can be accomplished without difficulty.
