1. A method for manufacturing viruses in an in vitro cell culture, comprising the following steps: a) providing a cell culture of avian epithelial cells chosen from at least one of the cell cultures deposited under deposition numbers DSM ACC3345, DSM ACC3346, DSM ACC3347, DSM ACC3348, DSM ACC3349; b) infecting at least some of the cells in the cell culture with virus particles; c) incubating the cells for a first period of time; and d) recovering viruses produced by the cell culture from a supernatant of the cell culture.
