| a papova-like virus infection of splendid parakeets (neophema splendida). | the lesions associated with a papova-like virus infection in two splendid parakeets (neophema splendida) are described. the most obvious microscopic lesion in both birds was enlargement of renal medullary collecting-duct epithelial cells. the nuclei of these cells were also enlarged, pleomorphic, and often bizarre, and intranuclear and intracytoplasmic virus-like particles (48 nm in diameter) were demonstrated within them. one bird also had a hepatopathy characterized by hepatocyte enlargement a ... | 2004 | 3675434 |
| a survey of a mixed species aviary provides new insights into the pathogenicity, diversity, evolution, host range, and distribution of psittacine and passerine adenoviruses. | a bourke's parrot (neopsephotus bourkii) originating from an aviary in australia, containing two species of parrots, five species of finch and a species of dove, was presented for necropsy. the bourke's parrot died from gastritis caused by macrorhabdus ornithogaster, but also had an interstitial nephritis and ureteritis with adenovirus-like inclusion bodies within collecting duct epithelial cells. the adenovirus causing the lesions was shown to be psittacine adenovirus-2 (psadv-2) using a pcr as ... | 2019 | 31081348 |
| development and validation of 2 probe-hybridization quantitative pcr assays for rapid detection of a pathogenic coxiella species in captive psittacines. | avian coxiellosis is an emerging cause of morbidity and mortality among captive psittacines, and the utility of a rapid detection test using easily obtained samples is paramount in a clinical setting. new sequences were obtained from 3 genes: groel, dnak, and rpob. we developed probe-hybridization quantitative pcr (qpcr) assays using groel and dnak genes. samples, including splenic aspirates, liver aspirates, whole blood, and choanal, conjunctival, and cloacal swabs, were collected from 4 psitta ... | 2020 | 32188352 |
| novel siadenovirus infection in a cockatiel with chronic liver disease. | a 15-year-old female cockatiel (nymphicus hollandicus) undergoing long term management for hepatopathy died and underwent necropsy. microscopic findings were consistent with chronic liver disease characterized by distorted hepatic architecture, fibrosis and biliary proliferation. the additional finding of large intranuclear inclusion bodies within hepatocytes and renal tubular epithelium prompted diagnostic next generation sequencing. the assembled sequences isolated from pooled kidney and liver ... | 2019 | 30711577 |
