| Summary: | Jianhua Guo,1 Lina Covaleda,1 J Jill Heatley,1 John A Baroch,2 Ian Tizard1, Susan L Payne,11Texas A&M University, College Station, TX, USA; 2USDA/APHIS Wildlife Services, Fort Collins, CO, USAAbstract: Avian bornavirus (ABV) matrix (M) genes were detected by RT-PCR on brain tissue obtained from 192 mute swans harvested from several Northeastern states. A RT-PCR product was detected in 45 samples. Sequencing of the PCR products confirmed the presence of ABV belonging to the ‘goose’ genotype. The prevalence of positive samples ranged from 28% in Michigan to 0% in northern New York State. Two Rhode Island isolates were cultured. Their M, N, and X-P gene sequences closely matched recently published sequences from Canada geese.Keywords: avian bornavirus, proventricular dilatation disease, reverse transcription, polymerase chain reaction, mute swans |
