- Aspergillosis in albatrossesPublication . Melo, Aryse Martins; Silva Filho, Rodolfo Pinho da; Poester, Vanice Rodrigues; Fernandes, Cristina Gevehr; von Groll, Andrea; Stevens, David A; Sabino, Raquel; Xavier, Melissa OrzechowskiAspergillosis is a respiratory fungal disease of importance in captive marine birds. The aim of this study was to describe the occurrence of aspergillosis in Thalassarche melanophris during rehabilitation events and to identify the etiological agent. All the albatrosses that were received for rehabilitation and died within a 2-year period were included in the study. The proportionate mortality rate caused by aspergillosis was 21.4% (3/14). One of the etiological agents was Aspergillus flavus/oryzae lineage, and the other was A. fumigatus sensu stricto. Our study suggests that aspergillosis can act as a limiting factor in the rehabilitation of albatrosses.

- Aspergillosis in free-ranging aquatic birdsPublication . Melo, Aryse Martins; Silva-Filho, Rodolfo Pinho da; Poester, Vanice Rodrigues; von Groll, Andrea; Fernandes, Cristina Gevehr; Stevens, David A.; Sabino, Raquel; Xavier, Melissa OrzechowskiDue to the difficulty in the access to free-ranging birds, data regarding Aspergillus infections in wild avian species is rare compared to captive wild and domestic birds. Objective: report three cases of Aspergillus section Fumigati causing fungal disease in free-ranging aquatic birds, with the identification of the causal agent to the species level. Case reports: The diagnosis of aspergillosis was performed by macroscopic lesions found during the necropsy and confirmed by culture. Molecular identification by partial sequencing of the calM and benA genes allowed to confirm Aspergillus fumigatus sensu stricto as the etiological agent of aspergillosis in Procellaria aequinoctialis (White-chinned petrel) (n = 1), Nannopterum brasilianus (Neotropical cormorant) (n = 1) and Chroicocephalus maculipennis (Brown-hooded gull) (n = 1). Conclusion: Larger studies regarding the importance of aspergillosis in free-ranging aquatic birds are necessary, as well as it potential role in the One Heath context.
