Endogenous lipid pneumonia is a rare inflammatory, non-infectious lung disease characterized by the accumulation of endogenous lipids in alveolar macrophages. It has been associated with bronchial obstruction, chronic lung inflammation, alveolar proteinosis and lipid storage disorders. A...

Microbiological studies of the sanitary and health status of psittacine birds that will be reintroduced is important in evaluating whether these animals act as carriers of pathogenic agents to other animals and humans. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry...

Among the parrots (Psittacidae family) kept as pets, the cockatiels (Nymphicus hollandicus), budgerigars (Melopsittacus undulatus) and lovebirds (Lovebirds spp.) stand out. Although the benefits from the presence of these birds in a household environment are acknowledged, little is known about the...

The black lion tamarin (Leontopithecus chrysopygus) is an endangered primate species, restricted to the Atlantic Forest fragments of São Paulo state, Brazil, with an estimated wild population of ~1600 individuals. Integrative studies between zoo (ex situ) and wild (in situ) animals are crucial to...

Bacterial diseases are common in ornamental fish, more frequently associated with ubiquitous bacteria from the aquarium environment. The disease can lead to fish mortality and cause high economic losses if not rapidly controlled. The aim of this study was to identify the main causative bacterial...

The avian beak is a dynamic structure in constant growth that is constituted by the maxillary and mandibular bones and covered by epidermic hems. Examples of acquired problems include malformations, necrosis of the beak or traumas such as perforations, lacerations, cracks and avulsions. A...

The feather mite genus Protonyssus Trouessart (Xolalgidae: Ingrassiinae) has included four species associated with Neotropical and Old World parrots. In this article, two new species are described from Brazilian parakeets: Protonyssus mironovi sp. nov. from Psittacara leucophthalmus (Statius...
