Complete DNA sequence of canine adenovirus type 1

MD Morrison, DE Onions and L Nicolson Department of Veterinary Pathology, University of Glasgow Veterinary School, UK. gvpa15@udcf.gla.ac.uk The complete DNA sequence of a field strain of canine adenovirus type 1 was determined by sequencing random fragments of viral DNA cloned into pBluescript. The virus has a genome of 30536 bp flanked by two identical 161 bp inverted terminal repeats. Thirty ORFs have been identified, based on genomic location or sequence identity with published adenoviruses. These are arranged into similar discrete regions found in the human adenoviruses. ORFs in the late region show greatest identity with published human adenovirus sequences, whereas the E3 and E4 ORFs show little or none.
