| heart failure in a macaw with atherosclerosis of the aorta and brachiocephalic arteries. | a female severe macaw (ara severa) that was at least 11 years old was evaluated for sudden onset of exercise intolerance and dyspnea. radiography revealed a large heart silhouette, an increase in prominence of the brachiocephalic arteries, and a diffuse increase in opacity of the lungs. lateral nonselective angiography revealed dilatation of both chambers of the right side of the heart and incomplete emptying of the right atrium. alterations in the shape and position of the left-side heart chamb ... | 1996 | 8870741 |
| diabetes mellitus concurrent with hepatic haemosiderosis in two macaws (ara severa, ara militaris). | diabetes mellitus was diagnosed in a 5-year-old male chestnut-fronted macaw (ara severa) and an 8-year-old female military macaw (ara militaris) based on persistent hyperglycaemia and glucosuria. hepatic biopsies showed marked hepatic haemosiderosis, while pancreatic biopsies showed no inflammatory lesions. repeatable and titratable responses to bovine or porcine protamine zinc insulin were recorded in both patients, who were followed up for more than 2 years. in addition, iron-elimination thera ... | 2007 | 17620181 |
| bacillus cereus infection outbreak in captive psittacines. | this study reports an uncommon epizootic outbreak of bacillus cereus that caused the sudden death of 12 psittacines belonging to the species anodorhynchus hyacinthinus (1 individual), diopsittaca nobilis (1 individual), ara severa (1 individual) and ara ararauna (9 individuals) in a brazilian zoo. post-mortem examination of the animals reveled extensive areas of lung hemorrhage, hepatic congestion, hemorrhagic enteritis and cardiac congestion. histopathological examination of the organs showed t ... | 2012 | 22902190 |
| sex determination in 58 bird species and evaluation of chd gene as a universal molecular marker in bird sexing. | the aim of this research was to test the chd gene (chromo helicase dna-binding gene) as a universal molecular marker for sexing birds of relatively distant species. the chd gene corresponds to the aim because of its high degree of conservation and different lengths in z and w chromosomes due to different intron sizes. dna was isolated from feathers and the amplification of the chd gene was performed with the following sets of polymerase chain reaction (pcr) primers: 2550f/2718r and p2/p8. sex de ... | 2015 | 22553188 |
| fatal proventricular dilatation disease in captive native psittacines in brazil. | an outbreak of proventricular dilatation disease (pdd), a fatal inflammatory disease of psittacines (aves: psittaciformes), is described in native brazilian psittacines. twenty captive psittacines that died of suspected pdd were necropsied and 10 were submitted to histopathology, reverse transcriptase pcr (rt-pcr), and immunohistochemistry (ihc) for avian bornavirus (abv). examined species were one pileated parrot (pionopsitta pileata), three vinaceous-breasted parrots (amazona vinacea), two blu ... | 2014 | 24758135 |
| cross-species amplification and optimization of microsatellite markers for use in six neotropical parrots. | short amplicon primers were redesigned for 17 microsatellite loci developed in st. vincent's amazon and six loci developed in blue-and-yellow macaw and tested using six species of neotropical parrot. polymorphism was observed at 12 loci in blue-and-yellow macaw, 10 in red-and-green macaw, 11 in scarlet macaw, 10 in chestnut-fronted macaw, 11 in red-bellied macaw and 16 in mealy parrot. number of alleles per locus ranged from two to 23 and expected heterozygosity ranged from 0.05 to 0.95. the res ... | 2008 | 21585906 |
