Abstract
Summary
Three phage isolates from live virus vaccines were characterized and found to be indistinguishable. The phage, ϕV-1, is a small isometric coliphage with a broad host range, an edge-to-edge distance of 54 nm, and contains double-stranded DNA with a molecular weight of about 27 × 106. It is difficult to grow in large volumes; but is very stable in bovine serum.
