Detection of avian polyomavirus from psittacine birds in Klang Valley
Avian polyomavirus (APV) primarily affects young birds and can cause mortality in wide range of psittacine and non-psittacine birds.Adult birds typically are resistant to infection; they will seroconvert and shed the virus for up to 90 days, then clear the infection. The typical presentation of APV-...
