Here, we report a novel bat adenovirus strain isolated from apparently healthy bats of the species Rhinolophus cornutus in Japan. The genome of the isolate was 36,506 bp in length and encoded at least 33 proteins. Phylogenetic analysis of the DNA polymerase amino acid sequence, which provides one demarcation criterion for adenoviral species, indicated that the isolate belongs to the species Bat mastadenovirus C in the genus Mastadenovirus. Most of the encoded proteins shared high sequence similarity with those of known bat adenovirus C strains detected in different species of Rhinolophus, whereas the fiber protein and some E3- and E4-related proteins shared moderate similarity, and only the large E3 protein, which contains several host immune-suppression-related motifs, showed considerably lower similarity.
