title: Restriction endonuclease analysis and physical mapping of the genome of porcine adenovirus type 5.
abstract: The HNF61 and HNF70 isolates of porcine adenovirus type 5 (PAV-5) were cultivated in PK-15 cells, and viral DNA was extracted from the infected cells by a modified Hirt procedure. The DNAs were digested by each of 9 restriction endonucleases, and fragments representing the entire genomes were cloned. Based on the sizes of the restriction enzyme fragments, the genome of each isolate was estimated to be 33.2 kb. Physical maps for the 9 restriction endonucleases were constructed. The physical maps of the two isolates were identical for 5 of the restriction endonucleases, but 4 enzymes revealed differences in restriction sites occurring mainly between map units 78 and 83, which may include the E3 region of the genome. There were no similarities between the physical maps of PAV-5 and those described for the other 4 serotypes of PAV.
