title: Oligonucleotide fingerprinting of the RNA of different strains of infectious bronchitis virus.
abstract: 11  distinct oligonucleotide fingerprints were obtained in studies of the RNA of 13 isolates of IBV. Different serotypes had distinct fingerprints, but so did varieties within a serotype; allowing a greater degree of strain differentiation than was previously possible. Some conclusions can be drawn from the fingerprints concerning theories of origin and spread of IBV.
