@article { , title = {Vetreccr R1 Text Final AL 27May21}, abstract = {Pinnae are vital structures for echolocation and survival in many species of bats. Pinnal lesions have been described as common in captive bats, but information on specific diseases affecting the pinnae is scarce. A collection of histological sections of lesional pinnae from 10 bats, archived by bat conservation centers worldwide, was examined to identify potential aetiologies of disease. No neoplastic changes were seen but all pinnae showed inflammation, most commonly intraepidermal pustular dermatitis, deep perivascular dermatitis, nodular and/or diffuse dermatitis, and panniculitis. All bats with deep inflammation had concurrent pinnal perichondritis and cartilage necrosis. Microbial overgrowth was frequent, and pyoderma was confirmed in two bats based on histopathological and culture findings. Keratinocytes with features characteristic of koilocytes were noted in five bats, however immunohistochemistry would be required to confirm viral infection. Although no single aetiological agent was identified, deep inflammation was common and severe highlighting the potential detriment to affected bats and the need for future study of these delicate structures.}, issn = {0042-4900}, journal = {Veterinary Record Case Reports}, publicationstatus = {Accepted}, publisher = {BMJ Publishing Group}, url = {https://rvc-repository.worktribe.com/output/1549119}, author = {Loeffler, Anette and Boone, Johann and Boone, Johann and Fountain, Kay and Williams, Jonathan and Lloyd, David H. and Killick, Rowena and Rodriguez Barbón, Alberto and Stidworthy, Mark F. and Loeffler, Anette} }
