Respiratory diseases, diagnostics, and treatment of marsupials

Primary respiratory disease is uncommon in marsupials, but generalized disease often involves the respiratory tract in these animals. Other disease entities may spread to involve the respiratory system secondarily. Treatment is challenging because most animals are severely compromised on presentation. Bacteria, viruses, parasites, fungi and yeasts, trauma, and neoplasia all can affect the respiratory systems of marsupials. Some of these conditions are only incidental findings, whereas others are pathogenic. Many therapies and diagnostic procedures are extrapolated from those in companion animal medicine and surgery. Despite the problems associated with the diagnosis and treatment of respiratory disease in marsupials, new therapeutic agents and diagnostic techniques are making these tasks easier and ultimately more successful.
