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. We combined morphological and molecular diagnostic(More)
Regarding the findings of Vanstreels et al. (2014), later analyses revealed that the blood sample of a tropical screech owl (Megascops choliba) that had been analyzed 4 weeks earlier at the same laboratory yielded a Haemoproteus sp. cyt-b sequence that was 100% identical to that obtained for penguin 586. This owl had been sampled in 2009 at Carapicuíba, SP,(More)
This study is the first report on mortality of Spheniscus magellanicus, penguin of South America, caused by Plasmodium tejerai, which was identified using morphological and molecular analyses. Blood stages (trophozoites, meronts and gametocytes) were reported and illustrated. The necropsy revealed marked splenomegaly and pulmonary edema, as well as moderate(More)
Avian malaria is a mosquito-borne disease caused by Plasmodium spp. Avian plasmodia are recognized conservation-threatening pathogens due to their potential to cause severe epizootics when introduced to bird populations with which they did not co-evolve. Penguins are considered particularly susceptible, as outbreaks in captive populations will often lead to(More)
A novel avipoxvirus caused diphtheritic lesions in the oesophagus of five and in the bronchioli of four Magellanic penguins (Spheniscus magellanicus) and also cutaneous lesions in eight Magellanic penguins housed in outdoor enclosures in a Rehabilitation Centre at Florianópolis, Santa Catarina State, Brazil. At the same time, another avipoxvirus strain(More)
The hyacinth macaw (Anodorhyncus hyacinthinus), considered the largest psittacine bird species in the world, is an endangered species, with a remaining population of approximately 6500 birds in the wild. To establish hematologic and plasma biochemical reference ranges and to verify differences related to sex, samples from 29 hyacinth macaws (14 males, 15(More)
Magellanic penguins (Spheniscus magellanicus) breed on the Atlantic and Pacific coasts of the southernmost parts of South America and migrate northward as far as Peru and Brazil. Serum samples (n = 100) from Magellanic penguins from three zoos and two rehabilitation centers (RCs) in Brazil were assayed for the presence of antibodies to Toxoplasma gondii by(More)
Cetacean lacaziosis-like disease or lobomycosis-like disease (LLD) is a chronic skin condition caused by a non-cultivable yeast of the order Onygenales, which also includes Lacazia loboi, as well as Paracoccidioides brasiliensis and P. lutzii, respectively responsible for lacaziosis and paracoccidioidomycosis in humans. Complete identification and(More)
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(More)
