Upper respiratory disease may be underrecognized in hedgehogs

Upper respiratory disease may be more common in hedgehogs’ noses than vets assumed

Respiratory disease in European hedgehogs sent to rehabilitation is often investigated as a lung problem, but a new Veterinary Pathology study suggests the upper airway deserves much more attention. In necropsies of 50 rehabilitating hedgehogs that died after showing respiratory signs, 56% had upper respiratory tract disease, according to the study abstract provided by the journal. Additional background from the authors’ earlier project updates suggests upper and lower respiratory disease were found at broadly similar rates in this population, with upper airway cases often presenting as severe rhinitis associated with gram-negative bacterial colonies, and with trauma, dental disease, or foreign bodies considered possible contributors. The work comes from Yannick Van de Weyer, Steve Bexton, and Joanna Mihr, with links to the University of Liverpool and RSPCA wildlife rehabilitation centers. (ewda.org)

Why it matters: For veterinary professionals, especially those handling wildlife casualties or advising rehabilitators, the study is a reminder not to anchor on pneumonia alone when a hedgehog presents with tachypnea, lethargy, or other respiratory signs. Prior literature already showed respiratory disease is a common cause of morbidity and mortality in European hedgehogs in rehabilitation, and recent work has highlighted how frequent parasitic lower respiratory disease can be. This new paper appears to widen the diagnostic frame: nasal cavity disease, rhinitis, oral disease, trauma, and mixed or secondary bacterial processes may all be part of the picture, which could affect workups, treatment decisions, and prognosis discussions.

What to watch: Watch for the full paper’s methods and organism-level findings to shape how wildlife hospitals prioritize nasal and oral exams, imaging, microbiology, and triage protocols in hedgehogs with respiratory signs. (ewda.org)
