Interim Results about examinations regarding various viruses:
Translated from the German periodical "Die Brieftaube" (2004, Nr. 8):
The presence of various viruses in pigeons suffering from Young Bird Sickness was determined at the Universities of Leipzig and Gießen.
- Adenovirus and Polyomavirus PCR (polymerase chain reaction) tests of the livers were negative as were subsequent attempts at culturing.
- PCR tests regarding Herpesvirus was positive in 15% which could also be confirmed through cultures.
- The presence of Circovirus could be confirmed in 90% with the PCR test and 100% of all blood tests were positive as were all tests of the oil gland.
The trigger of young bird sickness is the Circovirus in connection with other disease-causing agents. At the FCI-level a related study is running that concentrates itself on how Circovirus is spread. From this comes the question of how one can most effectively fight the virus.
