Goose hemorrhagic polyomavirus (GHPV) is the viral agent of hemorrhagic nephritis enteritis of geese (HNEG), a lethal disease of goslings. Although death is the most common outcome, geese that recover from HNEG are persistently infected. Here, we present the development of real-time SYBR Green real-time PCR targeted to GHPV and its use to assess the prevalence of GHPV infection in French geese flocks.

By using metagenomics, we identified a novel avian gammacoronavirus associated with this disease that is distantly related to turkey coronaviruses. Fatal respiratory diseases in humans have recently been caused by coronaviruses of animal origin.

Diseased birds displayed an acute severe dyspnoea, leading to death by asphyxia of more than 5% of the flock. The most specific pathological feature was a constant diffuse infraorbital sinusitis, along with a focal necrotic exudate inside the lumen of the upper respiratory tract, characterized microscopically as a mixed fibrinous and leucocytic material.

It was recently shown that GHPV can also be detected in Muscovy and mule ducks. The goal of the present study was to investigate the pathobiology of GHPV in ducks.
