molecular diagnosis of salmonella species in captive psittacine birds.	cloacal swabs were collected from 280 captive psittacine birds belonging to 13 species. samples of dna were tested by pcr using a pair of primers that amplify a 284 base pair fragment of the salmonella genus inva gene, and the pcr-positive samples were tested by standard microbiological techniques. thirteen per cent of the samples were positive by pcr, but negative by microbiological techniques. the infection rates were significantly different among the 13 species, the most commonly infected bei ...	2008	18567929
hepatic hemosiderosis in red-spectacled amazons (amazona pretrei) and correlation with nutritional aspects.	alimentary habits of free-living psittaciformes vary significantly among different species. amazona pretrei is under risk of extinction and has very specific free-living dietary habits, which are based on paraná pine seeds. hemosiderosis is a pathologic process characterized by intracellular accumulation of iron without other evident lesions. it is associated with increased prevalence of infections, neoplasms, and hepatopathies. the purpose of this study was to quantify hepatic hemosiderin depos ...	2010	21313859
development and characterization of novel microsatellite loci for the blue-fronted amazon (amazona aestiva, psittaciformes, aves) and cross-species amplification for other two threatened amazona species.	parrots are among the most threatened avian groups of the world, with illegal pet trade being a major threat to some amazon (amazona genus) and macaw (ara and anodorhynchus genera) species. population genetic studies and effective control of commercial breeders are important actions for the conservation of these parrot species; however, few microsatellite loci are available for most amazona species to date. in this study, 25 polymorphic microsatellite loci were identified in silico and character ...	2019	30617658
the identity of the mysterious "azara's parakeet" sittace flaviventris wagler, 1832.	sittace flaviventris wagler, 1832 was the name given to azara's no. 276 "maracaná cabeza y encuentro roxos", but since then the identity of the species has remained a mystery. based on a tail-less domestic individual, it has most often been attributed to an aberrant aratinga parakeet, and is currently considered a doubtful taxon. in this note the identity of "azara's parakeet" is confirmed as red-spectacled amazon amazona pretrei (temminck, 1830), a species that still occurs today in the region ...	2020	29947677
