Aspergillosis in free-ranging aquatic birds.

Unlabelled: Due to the difficulty in the access to free-ranging birds, data regarding infections in wild avian species is rare compared to captive wild and domestic birds.

Objective: report three cases of section 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.

Aspergillosis in albatrosses.

Aspergillosis 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.

Tuberculosis caused by Mycobacterium pinnipedii in a wild South American sea lion Otaria flavescens stranded in southern Brazil.

Tuberculosis (TB) in pinnipeds is typically caused by Mycobacterium pinnipedii, which has also been associated with infections in other species, such as cattle and humans. As a result, this pathogen has zoonotic potential and is a public health concern. In 2016, a female South American sea lion Otaria flavescens in southern Brazil presented with emaciation and severe dyspnea and died within 3 h of capture.

INCIDENCE DENSITY, PROPORTIONATE MORTALITY, AND RISK FACTORS OF ASPERGILLOSIS IN MAGELLANIC PENGUINS IN A REHABILITATION CENTER FROM BRAZIL.

Aspergillosis, an opportunistic mycosis caused by the Aspergillus genus, affects mainly the respiratory system and is considered one of the most significant causes of mortality in captive penguins. This study aimed to examine a 6-yr period of cases of aspergillosis in penguins at the Centro de Recuperação de Animais Marinhos (CRAM-FURG), Rio Grande, Brazil. A retrospective cohort study was conducted using the institution's records of penguins received from January 2004 to December 2009.

Epidemiology and pathology of avian malaria in penguins undergoing rehabilitation in Brazil.

Seabird rehabilitation is a valuable strategy to mitigate the impacts of oil pollution and other anthropogenic factors, and can significantly contribute to the conservation of penguins. However, infectious diseases such as avian malaria (Plasmodium spp.) can hamper the success of rehabilitation efforts.

Survival and movements of Magellanic penguins rehabilitated from oil fouling along the coast of South America, 2000-2010.

Oil pollution is a significant conservation concern. We examined data from six institutions along the coast of South America: Emergency Relief Team of the International Fund for Animal Welfare, Fundación Mundo Marino, Centro de Recuperação de Animais Marinhos, Natura Patagonia, Associação R3 Animal, and Mar del Plata Aquarium and data from resightings in Argentina, Brazil, Chile and Falkland/Malvinas Islands. From 2000 to 2010, 2183 oiled Magellanic penguins were rehabilitated as part of the routine activities of these institutions or during emergency responses to eight oil spills in which they were involved; all rehabilitated penguins were flipper banded and released.

Magellanic penguin mortality in 2008 along the SW Atlantic coast.

Magellanic penguins migrate from Patagonia reaching northern Argentina, Uruguay, and southern Brazil on their winter migration, in parallel with the seasonal pulse of anchovy spawning. In 2008, Magellanic penguins went further north than usual. Many died and a few swam nearly to the Equator.
