Различный уровень данного состояния у новорожденного и взрослого организмов животных должны быть основаны на том, что плод и новорожденный после рождения впервые вступает в контакт с антигеном, тогда как взрослый организм уже имеет частичную сенсибилизацию. Хроническое носительство возбудителей у животных и их влияние на распространение инфекционного процесса это насущная проблема современной ветеринарной медицины. Возможность применения вакцинации у новорождённых ограничивается присутствием материнских антител, которые оказывают иммуносупрессивное действие. Высокий уровень функциональных резервов беременного организма важное значение в профилактике внутриутробного инфицирования. Инфицирование в пренатальный период развития сказывается на процессах роста и развития плода с одной стороны, а с другой - происходит изо-иммунизация материнского организма антигенами плода, сопровождающаяся повышением чувствительности организма с преобладающим проявлением клеточных феноменов, при отсутствии усиленного синтеза антител. Учитывая высокую значимость функциональных резервов новорожденного организма важное значение имеет внутриутробное развитие и полноценность плацентарного барьера. Выявление носительства инфекционного агента в неактивной фазе в период беременности различного гестационного периода необходимо рассматривать с позиций авидности и серопозитивности беременных животных. Высокое разнообразие клинических проявлений внутриутробного инфицирования требует разработки малоинвазивных методов антенатального и интранатального прогнозирования, позволяющих на этапе беременности и/или родов оценить не столько наличие возбудителя, сколько риск развития инфекционного заболевания плода и новорожденного, осложнений раннего неонатального периода.</p></abstract><trans-abstract xml:lang="en"><p>Changes of immunological reactivity to viral and bacterial antigens can cause increased susceptibility to infectious diseases. Different levels of this changes in newborn and adult animal organisms should be based on the fetus and newborn reactivity, first coming into contact with the antigen after birth, whereas the adult organism already has partial sensitization. Chronic vectors of pathological agents in animals and their influence on the spread of infectious process is a persisting problem of modern veterinary medicine. The ability to use vaccination in newborns is limited by the presence of ma ternal antibodies that have immunosuppressive effects. High level of functional abilities of pregnant organism is important in prevention of intrauterine infection. Infection in the prenatal period of development affects fetal growth and development processes on the one hand, and on the other - isoimmunization of the maternal organism with fetal antigens occurs, accompanied by increased sensitivity of the organism with predominant manifestation of cellular phenomena, in the absence of increased synthesis of antibodies. Given the high importance of the functional reserves of the newborn organism, the intrauterine development and completeness of the placental barrier are important. Detection of the transportation of infectious agent in inactive phase during pregnancy of different gestational period should be considered from the point of view of avidity and seropositivity of pregnant animals. The high variety of clinical manifestations of intrauterine infection requires the development of minimally invasive methods of antenatal and intranatal prediction, which allow at the stage of pregnancy and/or childbirth to assess the presence of an agent in a very small amount as the risk of the future development of infectious disease of the fetus and newborn, or complications of the early neonatal period.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>иммунобиологический статус</kwd><kwd>иммунологическая ареактивность</kwd><kwd>феномен конкуренции антигенов</kwd><kwd>беременные животные</kwd><kwd>immunobiological status</kwd><kwd>immunological a-reactivity</kwd><kwd>antigen competition phenomenon</kwd><kwd>pregnant animals</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">A novel real-time pcr assay for quantitative detection of campylobacter fetus based on ribosomal sequences / G.
