2012-07-27 Avian polyomavirus (APV) infections have been reported to cause fatal disease in a wide range of psittacine species. Here we demonstrate APV infections in buzzards (Buteo buteo) and in a falcon (Falco tinnunculus) found dead in Germany, and in lovebirds (Agapornis pullaria) with fatal disease, wild-caught in … Avian polyomavirus (APV) was diagnosed in a single bird at the authors’ institution (Estrin et al., manuscript in preparation). The adult female presented with unilateral periorbital swelling and discrete subcutaneous nodules, predominantly on the neck, thorax, and wings (Fig.
In psittacine birds with enlarged kidneys and other minor changes, glomerulopathy with a positive PAS (periodic acid-Schiff) reaction may indicate infection with avian Polyomavirus . The PAS reaction in Polyomavirus occurs due to the, sometimes massive, deposition of immune complexes [ 12 ]. Circella E, Caroli A, Marino M, et al. Polyomavirus Infection in Gouldian Finches (Erythrura gouldiae) and Other Pet Birds of the Family Estrildidae.

In Australia, flocks of wild cockatoos may have a disease prevalence of 20% and a seroprevalence of 60% to 80% and infection is probably maintained in a population by diseased birds and contaminated nest hollows.
