| Polyomavirus infection in canary (Serinus canaria) colony |
| Polyomavirus was diagnosed in the canary (Serinus canaria) colony with debilitation and mortality of young -six- weeks old and adult birds which rarely survive longer than two years. Main pathological changes in necropsied canaries were splenomegaly, hepatomegaly and kidney swelling. Microscopically intranuclear inclusion bodies were observed in the liver and kidneys and necrotic and inflammatory changes were present in that organs. In red and black gloster less susceptibility was observed, also agate canaries were quite resistant. Concurrent infections, like mycobacteriosis, coccidiosis, atoxoplasma and bornavirus were detected in individual birds. Diagnosis was confirmed by nested PCR test. Polyomavirus was considered as primary etiological agent of the disease and immunosuppression. |
