[Dynamics of maternal and post-infection adenovirus antibodies in fowl].

The epizootological study of the adenovirus infections of poultry, conducted with the use of the serum virus-neutralizing test, gives a picture of the distribution of various serotypes of avian adenoviruses in the poultry population, or in the largest poultry stocks in Czechoslovakia. There is a description of the occurrence of type-specific antibodies in serums of different age categories of poultry acting against seven available virus serotypes. An ascending trend in positive findings of adenovirus antibodies was observed with increasing age of the birds. The dynamics of yolk or maternal antibodies was studied under experimental conditions after the application of virus antigen.
