title: Unique virus-related DNA sequences in sheep progressive pneumonia lung.
abstract: Hybridization studies with [3H]-cDNA of progressive pneumonia, maedi and visna viruses demonstrate that lung DNA from sheep afflicted with progressive interstitial pneumonia possesses virus-related sequences not present in normal sheep lung DNA.
