[Complement fixation reaction (CFR) in adenovirus infections of calves].
Studied was the complement-fixation reaction in the diagnosis of the adenovirus infections in calves. It was found that the test is specific and sensitive. A virus suspension of tissue cultures was used as an antigen, its titer varying from 1:8 up to 1:16. Specific complement-fixing antibodies were detected mainly in survivals at serum dilution of up to 1:64. Specific antibodies were established in undiluted sera too taken from animals of infected herds. In some of the tested sera there were both complement-fixing and precipitating antibodies. In calves treated with a live vaccine against adenoviruses the dynamics of the complement-fixing antibodies was followed up.
