Abstract

Immunological aspects of the relationship in the functional system “mother-fetus” are consciously important both in the scientific and practical direction of the life of living organisms. The formation of the main parameters of isoimmunization is an equivalent aspect in relation to the basics of the formation of artificial tolerance mechanisms. Changes in immunological reactivity to viral and bacterial antigens may cause increased susceptibility to infectious diseases. Different levels of this condition in newborn and adult animal organisms should be based on the fact that the fetus and newborn after birth first comes into contact with the antigen, while the adult body already has partial sensitization. Chronic carrier of pathogens in animals and their influence on the spread of the infectious process is an urgent problem of modern veterinary medicine. The possibility of vaccination in newborns is limited by the presence of maternal antibodies that have an immunosuppressive effect.The immunological relationship between the fetal mother’s body in a non-inbred population should be considered in two aspects: the effects caused by maternal antigens in the fetus; the effect of fetal antigens on the mother’s body. Level of functional reserves of the pregnant body is important in the prevention of intrauterine infection.
