By the 12th serial passage in medium, infectivity of B anserina for chicks was lost. Electron microscopy did not reveal structural differences between non-infective and infective cultured organisms. Changes in the protein profiles were found by electrophoresis as the organisms were passed in culture.}, number={1}, journal={RESEARCH IN VETERINARY SCIENCE}, author={LEVINE, JF and DYKSTRA, MJ and NICHOLSON, WL and WALKER, RL and MASSEY, G}, year={1990}, month={Jan}, pages={64–69} }
