| baylisascaris procyonis encephalitis in patagonian conures (cyanoliseus patagonus), crested screamers (chauna torquata), and a western canadian porcupine (erethizon dorsatum epixanthus) in a manitoba zoo. | neurological disease occurred in 4 patagonian conures (cyanoliseus patagonus), 2 crested screamer chicks (chauna torquata), and 1 western canadian porcupine (erethizon dorsatum epixanthus) at a manitoba zoo. baylisascaris procyonis, the common raccoon roundworm, not previously identified in manitoba, is considered the likely cause of neural larval migrans in these cases. | 2008 | 19043485 |
| reovirus infection in two species of psittaciformes recently imported into italy. | an outbreak of reovirus infection with high mortality in two groups of recently imported psittacine birds is reported. the disease in the two species involved, african grey parrots (psittacus erithacus erithacus) and australian king parrots (alisterus scapularis), had differences in clinical presentation and gross lesions. reovirus particles were observed by electron microscopy and ultrastructural examination of tissues, and two viruses were isolated in cell culture, one from each bird species. ... | 2001 | 19184872 |
| severe neurologic disease and chick mortality in crested screamers (chauna torquata) infected with a novel gyrovirus. | gyroviruses are small, single stranded dna viruses in the family anelloviridae. in chickens, the type virus (chicken anemia virus; cav) causes epidemic disease in poultry flocks worldwide. in 2007 and 2008, young crested screamers (chauna torquata) at a zoo in wisconsin, usa, died of neurologic disease with clinical and pathological features resembling cav infection. conventional diagnostics were negative, but molecular analyses revealed coinfection of an affected bird with three variants of a n ... | 2018 | 29852412 |
| mortality of four captive-born crested screamer chicks (chauna torquata). | crested screamers, a unique, mainly terrestrial avian species native to south america, are known to have a markedly high chick mortality rate in captivity, ranging from 61% to 94%; however, there is very limited information on this species' natural history within the literature, and even less about common diseases that affect them. four captive-born crested screamer chicks (chauna torquata) at a u.s. zoological institution died acutely from different causes over the course of 2.5 months. althoug ... | 2019 | 31360650 |
