Formatted Abstract/Summary
Psittacine beak and feather disease (PBFD), caused by beak and feather disease virus (PBFDV) is the most significant infectious disease in psittacine birds. The virus infects and kills the cells of the feather and beak as well as cells of the immune system, causing irreversible feather dystrophy and loss, beak abnormalities and variable degrees of immunosuppression which may result in lethal secondary infection. Spontaneous recovery does occur although most chronically affected birds do not recover. Clinically the disease can present as acute or chronic, affecting both young and mature birds. Acute infections are usually accompanied by signs of illness with severe mortality and feather abnormalities in young birds, whereas chronic infections can be insidious in progression, making diagnosis difficult. In these cases, infection with PBFD must be differentiated from avian polyomavirus and, to a lesser extent, herpesvirus, which appears to be a recent introduction to Australia, with very little as yet known about its incidence and distribution.

The aim of this study was to use current serological diagnostic tools and a qPCR detection assay to investigate virus excretion in different sample types collected from PBFD-infected lorikeets over a period of 18 months. Only lorikeets were studied in order to minimise the impact of possible virus genotypes affecting detection of the virus.
