Tumour or haemorrhage?: Differential diagnosis of an unknown mass within the brain of a budgerigar (Melopsittacus undulatus) using a novel imaging pipeline

Veterinary Record Case Reports, Volume 12, Issue 3, September 2024.
Abstract We report on a previously healthy zoo specimen of an adult budgerigar (Melopsittacus undulatus, obtained with permission from Southwick's Zoo) found deceased in its enclosure. To assess cause of death and ensure the absence of an infectious neoplasia, we used an integrated multiscale brain‐imaging workflow, previously only used on mammals. The

Circular RNA alterations are involved in resistance to avian leukosis virus subgroup-J-induced tumor formation in chickens

OncoTarget, 2017
Avian leukosis virus subgroup (ALV-J) is an oncogenic neoplasm-inducing retrovirus that causes significant economic losses in the poultry industry. Recent studies have demonstrated circular RNAs (circRNAs) are implicated in pathogenic processes; however,

Myxoid leiomyosarcoma of the oviduct and uterus in a Cockatiel (Nymphicus hollandicus)

Veterinary Medicine and Science, Volume 10, Issue 4, July 2024.
An 11‐year‐old female Cinnamon Cockatiel (Nymphicus hollandicus) was presented with an abdominal bulge. Exploratory celiotomy revealed a large intraluminal mass extending through the magnum to the uterus. Histopathological features of the mass, coupled with Masson's trichrome and Alcian blue special staining, and immunohistochemistry for α‐SMA, desmin,

The widespread keeping of wild pets in the Neotropics: An overlooked risk for human, livestock and wildlife health

People and Nature, Volume 6, Issue 3, Page 1023-1035, June 2024.
Abstract Zoonoses constitute a major risk to human health. Comprehensive assessments on the potential emergence of novel disease outbreaks are essential to ensure the effectiveness of sanitary controls and to establish mitigating actions. Through a continental‐scale survey of rural human settlements conducted over 13 years in 15 Neotropical countries ...
