Plain-English summary
An adult Blue Fronted Amazon parrot was brought to the vet because it was vomiting, lethargic, and had undigested seeds in its droppings, along with severe anemia. After about two months of treatment, tests confirmed the presence of Avian Polyomavirus (APV) in both its blood and feces, while other viruses were ruled out. Fortunately, after six months, follow-up tests showed that the parrot was no longer shedding the virus in its droppings. This case highlights how APV can cause unusual symptoms like severe anemia in birds, and it underscores the importance of specific testing for accurate diagnosis.

Abstract
An adult Blue Fronted Amazon parrot (A. aestiva) presenting with emesis, apathy, undigested seed in feces, and severe anemia was treated for approximately 2 months. Upon radiographic examination, an enlarged kidney was the only alteration. PCR for avian Bornavirus, Circovirus, and Polyomavirus was performed for the feces and blood. The results were positive for APV in both samples and negative for the other viruses. After 6 months, the feces from the same animal were negative for APV. Because the animal was positive for APV in both the feces and the blood, it is likely that these clinical symptoms were due to Polyomavirus infection. Severe anemia is an unusual clinical sign of Polyomavirus, and this study aims to identify novel differential diagnostic criteria for the disease.
