[Disseminated aspergillosis in a loon]

Area of Science:

• Veterinary Mycology
• Avian Pathology
• Wildlife Disease

Background:

• Aspergillosis is a significant fungal disease affecting birds.
• Generalized mycosis can be fatal in avian species.
• Fungal infections pose a threat to both captive and wild bird populations.

Purpose of the Study:

• To document a fatal case of generalized aspergillosis in a diver bird (Gavia arctica).
• To detail the mycological and histopathological findings of Aspergillus fumigatus infection.
• To review the prevalence of aspergillosis in various bird groups.

Main Methods:

• Mycological culture and identification of the causative agent.
• Histopathological examination of affected tissues, primarily the lungs.
• Literature review of reported aspergillosis cases in birds.

Main Results:

• A case of generalized aspergillosis caused by Aspergillus fumigatus in Gavia arctica is described.
• Significant histopathological changes were observed in the lungs.
• The infection proved fatal due to extensive organ damage.

Conclusions:

• Aspergillus fumigatus can cause severe, fatal generalized mycosis in diver birds.
• Detailed mycological and histopathological analysis is crucial for diagnosing avian aspergillosis.
• Aspergillosis is a recognized threat across diverse avian orders, including wild species.
