Serological Surveillance and Risk Factor Analysis for Parrot Bornavirus in Taiwan [PDF]

Transboundary and Emerging Diseases, Volume 2024, Issue 1, 2024.
Parrots are traded globally and pose a substantial risk for disease transmission involving parrot‐specific pathogens. Parrot bornavirus (PaBV) belongs to the Bornaviridae family and encompasses two clades: alphapsittaciforme (PaBV‐1 to ‐4, PaBV‐7, and ‐8) and betapsittaciforme (PaBV‐5 and PaBV‐6). These clades cause proventricular dilatation disease, a

Experimental induction of proventricular dilatation disease in cockatiels (Nymphicus hollandicus) inoculated with brain homogenates containing avian bornavirus 4 [PDF]

Virology Journal, 2009
Background Proventricular dilatation disease (PDD) is a fatal disorder of psittacine birds worldwide. The disease is characterized by lymphoplasmacytic infiltration of the central and peripheral nervous systems, leading to gastrointestinal motility and ...

Surveillance of Parrot Bornavirus in Taiwan Captive Psittaciformes [PDF]

Viruses
Parrot bornavirus (PaBV) is an infectious disease linked with proventricular dilatation disease (PDD) with severe digestive and neurological symptoms affecting psittacine birds. Despite its detection in 2008, PaBV prevalence in Taiwan remains unexplored.

Distinct 5′ UTR Requirements for Translation of the Bicistronic X/P mRNA Among Avian Orthobornaviruses [PDF]

Microbiology and Immunology, Volume 70, Issue 2, Page 80-90, February 2026.
ABSTRACT Orthobornaviruses express X and the phosphoprotein (P) from a bicistronic X/P mRNA, and these proteins regulate polymerase activity. In mammalian orthobornaviruses, the 5′ untranslated region (5′ UTR) of the X/P mRNA controls the translational balance between X and P and thereby promotes efficient replication.
