dc.description.abstract Bovine adenovirus type 3 (BAV3) is a medium size DNA virus that causes respiratory and gastrointestinal disorders in cattle. The viral genome consists of a 35,000 base pair, linear, double-stranded DNA molecule with inverted terminal repeats and a 55 kilodalton protein covalently linked to each of the 5' ends. In this study, the viral genome was cloned in the form of subgenomic restriction fragments. Five EcoRI internal fragments spanning 3.4 to 89.0 % and two Xb a I internal fragments spanning 35.7 to 82.9 % of the viral genome were cloned into the EcoRI and Xbal sites of the bacterial vector pUC19. To generate overlap between cloned fragments, ten Hi n dIll internal fragments spanning 3.9 to 84.9 and 85.5 to 96% and two BAV3 BamHI internal fragments spanning 59.8 to 84.9% of the viral genome were cloned into the HindllI and BamHI sites of pUC19. The HindlII cloning strategy also resulted in six recombinant plasmids carrying two or more Hi ndII I fragments. These fragments provided valuable information on the linear orientation of the cloned fragments within the viral genome. Cloning of the terminal fragments required the removal of the residual peptides that remain attached to the 5' ends of the genome. This was accomplished by alkaline hydrolysis of the DNA-peptide bond. BamH I restriction fragments of the peptide-free DNA were cloned into pUC19 and resulted in two plasmids carrying the BAV3 Bam HI terminal fragments spanning 0 to 53.9% and 84.9 to 100% of the viral genome. en_US
