title: Assignment of two new host range types to the P2 family of temperate coliphages.
abstract: Six non-inducible coliphages which grow on Escherichia coli C but not on K12 (C-specific) were shown to be antigenically related to P2. All six were shown to be P4 helpers and some of them could also recombine with P2.
