title: Absence of interference during high-multiplicity infection by clonally purified vesicular stomatitis virus.
abstract: Stocks of vesicular stomatitis virus free of defective interfering particles were produced by serial clonal isolation. High-multiplicity infections with these stocks led to no interference or formation of defective interfering particles. Defective interfering particles were generated by three successive passages at high multiplicity.
