Post-vaccination immunity to acute respiratory virus infections in calves with intestinal disorders
This article discusses the formation of highly specific immune response in calves and the dependence of the antibody productions with the biosynthetic capabilities of cells of the immune system, mechanisms of depletion of biosynthetic resources and reduction of resistance of an organism at pathological processes in the gastrointestinal tract of non-infectious origin. The author analyzed the typical features of the formation of the immune response against pathogens of acute respiratory viral infections (ARVI) in young cattle with digestive disorders of infectious etiology in spring and summer. Identified and the necessity of preventive measures aimed at prevention of development of alimentary dyspepsia in calves the first month of life with the purpose of formation of a full immune response to the active specific immunization against SARS-diseases and prevent the spread of field strains of SARS among the animal population. Titers of antibodies to the causative agent of SARS was diagnosed in 80% of animals undergoing non- communicable disorders of the gastrointestinal tract of the surveyed, was at the projective level. Calves with nutritional dyspepsia violations occur biosynthetic processes in the antibody productions.
