Abstract
Bovine adenovirus type 7 (BAdV-7) is one of the most important respiratory and enteric pathogens in the cattle industry. Although live attenuated vaccines are used to control the virus in Japan, limited information is available on the genomic regions that determine viral pathogenicity. We determined the complete genome sequence of the attenuated BAdV-7 strain TS-GT. The genome is 30,052 bp long and contains 45-bp inverted terminal repeats and 30 predicted genes. A genome sequence comparison showed that 99.9% of the TS-GT genome is identical to the prototypic and pathogenic BAdV-7 strain Fukuroi; however, the TS-GT genome contains a novel mutation and four indels. We describe here potential relationships between these genomic changes and the biological characteristics of BAdV-7.

Molecular characterization of a bovine adenovirus type 7 (Bovine Atadenovirus F) strain isolated from a systemically infected calf in Germany. Virol J 2022; 19:89.

Abstract
Bovine adenovirus 7 (BAdV-7) is an unclassified member of the genus Atadenovirus with a worldwide distribution and has been reported to induce clinical disease of varying severity in infected cattle, ranging from asymptomatic infections to severe enteric or respiratory disease. In this study, we used next-generation sequencing to obtain the first complete genome sequence of a European strain of BadV-7, from pooled spleen and liver tissue obtained from a deceased newborn Limousin calf. Histopathological analysis and electron microscopy showing systemic lesions in multiple organs with intranuclear amphophilic inclusions observed in endothelial cells in multiple peripheral tissues. Virus isolation was readily achieved from tissue homogenate using bovine esophagus cells (KOP-R), a strategy which should facilitate future in vitro or in vivo BAdV-7 studies. Phylogenetic analysis of available genome sequences of BAdV-7 showed that the newly identified strain groups most closely with a recent BAdV-7 strain, SD18-74, from the USA, confirming that this newly identified strain is a member of the Atadenovirus genus. The fiber gene was found to be highly conserved within BAdV-7 strains but was highly divergent in comparison to Ovine adenovirus 7 (OAdV-7) (39.56% aa sequence identity). Furthermore, we report a variable region of multiple tandem repeats between the coding regions of E4.1 and RH5 genes. In summary, the presented pathological and molecular characterization of this case suggests that further research into the worldwide molecular epidemiology and disease burden of BAdV-7 is warranted.

Abstract
We present the first complete genome sequence of an aviadenovirus Oriolus adenovirus (OrAdV) sequenced from the cloaca of a Oriolus chinensis (a passerine bird widely distributed in Asia), which was collected from an island off the east coast of China. Thirty-one protein coding genes were predicted in this 40425-bp-long genome. OrAdV genome is highly divergent and has only 57% average protein identity compared with other aviadenovirus genomes. Comparative genomic analysis indicates that this passerine virus is a new species of aviadenovirus. One unique thymidylate kinase gene was discovered in OrAdV genome. This gene is absent in other adenovirus genomes and usually reported to occur in herpesvirus. Protein sequence alignment against all known proteins indicates that this gene may be originated from ancient horizontal gene transfer event between virus and parasitic eukaryote like protozoan. This new aviadenovirus genome enriches the genomic information of adenovirus and suggests that there is a large unknown space of adenovirus world.

Identification and genetic characterization of an isolate of bovine adenovirus 7 from the United States, a putative member of a new species in the genus Atadenovirus. Arch Virol 2021; 166:2835-2839. [PMID: 34319454 DOI: 10.1007/s00705-021-05184-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Accepted: 06/04/2021] [Indexed: 11/25/2022]
Abstract
The bovine adenovirus 7 (BAdV-7) isolate SD18-74 was recovered from lung tissue of calves in South Dakota. The 30,043-nucleotide (nt) genome has the typical organization of Atadenovirus genus members. The sequence shares over 99% nt sequence identity with two Japanese BAdV-7 sequences, followed by 74.9% nt sequence identity with the ovine adenovirus 7 strain OAV287, a member of the species Ovine atadenovirus D. SD18-74 was amplified in both bovine and ovine primary nasal turbinate cells, demonstrating greater fitness in bovine cells. The genomic and biological characteristics of BAdV-7 SD18-74 support the inclusion of the members of the BAdV-7 group in a new species in the genus Atadenovirus.
