Incidence of Pigeon Circovirus in Eurasian Colared-Dove (Streptopelia decaocto) Detected by Nested PCR

摘要

The paper describes the first demonstration of pigeon circovirus in Eurasian collared-dove (Streptopelia decaocto). Nested PCR was used to examine birds of the Columbiform.es family. Pigeon circovirus DNA was identified in the bursa of Fabricius of anaccidentally caught dove by nested PCR after the second reaction. Impaired feathers and other clinical signs observed could not, however, be attributed to circoviral infection. The sequence of the amplified PCR product - middle of the capsid protein gene - was compared against all available circovirus sequences. Both the nucleotide and the derived amino acid sequence have a very close similarity to pigeon circovirus sequences. It may therefore be concluded that the sample was demonstrated to contain pigeon circovirus or another very similar virus. We therefore assume that pigeon circovirus may infect doves, too. Whether it is a special subtype or whether doves may be infected by common pigeon circovirus strains cannot be concluded with certainty fromthe existing results.
