Influence of vaccination against reovirus tenosynovitis on the dynamics of immunomorphological and serological indicators of rearing chickens

Abstract

The article presents the results of the study of the immunomorphological changes in the replacement young hens, when using the domestic live vaccine from the strain KMIEV-V118 and the similar foreign vaccine, as well as the immunogenic activity of these vaccines. Our studies suggest that immunization rearing poultry against reovirus tenosynovitis both domestic vaccine and foreign counterpart in the chicken immune organs is a series immunomorfologicheskih changes, characterized by activation plazmotsitarnoy reaction in the bursa of Fabricius, spleen, cecal tonsils, as well as in lymphoid diverticulum. At the same time, a vaccinated livestock has a correlation of immunomorphological and serological parameters.
