Молодь получена в условиях неволи от самок, отловленных беременными из поволжских популяций. В крови сеголетков E. dione преобладали эозинофилы и базофилы, общее содержание мононуклеарных клеток (агранулоцитов) было меньше по сравнению с сеголетками N. tessellata и N. natrix. При этом виды рода Natrix различались по содержанию всех трех типов мононуклеарных клеток: доля азурофилов и моноцитов была выше у N. tessellata, а доля лимфоцитов – у N. natrix. Основной вклад в баланс мононуклеарных клеток вносили лимфоциты. Лейкоцитарный состав крови молоди не имел ярко выраженного лимфоцитарного профиля, вклад специфической составляющей в общую адаптивную реакцию организма сеголетков к окружающим условиям был небольшим. По содержанию лимфоцитов изученные виды расположились в порядке убывания в следующем ряду: N. natrix (Me – 60.00, IQR – 2.50) → N. tessellata (52.00, 6.00) → E. dione (40.00, 5.00). Повышенное значение индекса сдвига лейкоцитов у сеголетков E. dione свидетельствовало о преобладающей роли в иммунном ответе гранулоцитов при некотором отставании клеток лимфоцитарно-моноцитарного звена и более поздней активации эффекторного звена иммунного ответа (лимфоцитов) по сравнению с сеголетками N. natrix и N. tessellata. При снижении специфической реакции иммунной системы в организме E. dione наблюдалась компенсаторная активация неспецифической защитной системы крови. Повышение содержания в крови молодых змей гранулоцитов являлось характерным показателем возрастания средового стресса, оцениваемого по интегральному лейкоцитарному показателю – индексу соотношения гетерофилов и лимфоцитов. Интегральные лейкоцитарные индексы отражали несбалансированность адаптивного ответа системы крови у сеголетков, содержавшихся в неволе, по отношению к взрослым самцам и самкам из природных популяций.</p></abstract><trans-abstract xml:lang="en"><p>A comparative interspecific assessment of the leukocyte profile of young Elaphe dione, Natrix natrix and N. tessellata is given. Juvenile snakes were obtained in captivity from females captured, being pregnant, from Volga populations. Eosinophils and basophils predominated in the blood of young E. dione, the total content of mononuclear cells (agranulocytes) was lower compared to the young of N. tessellata and N. natrix. At the same time, the species of the genus Natrix differed in the content of all three types of mononuclear cells, namely: the proportion of azurophils and monocytes was higher in N. tessellata, and that of lymphocytes was higher in N. natrix. The main contribution to the balance of mononuclear cells was made by lymphocytes. The leukocyte composition of young snakes had no pronounced lymphocytic profile, the contribution of the specific reactivity of the organism to the overall adaptive response of the body of young snakes to environmental conditions was small. According to the content of lymphocytes, the studied species were arranged in descending order in the following row: N. natrix (Me – 60.00, IQR – 2.50) → N. tessellata (52.00, 6.00) → E. dione (40.00, 5.00). The increased value of the leukocyte shift index in E. dione young testified to the predominant role of granulocytes in the immune response with some lag of lymphocyte-monocyte cells and later activation of the effector link of the immune response (lymphocytes) compared with young of N. natrix and N. tessellata. While the specific reaction of the immune system decreased, a compensator activation of the nonspecific protective blood system was observed in the organism of E. dione. The increase in the content of granulocytes in the blood of young snakes was a characteristic indicator of an increase in environmental stress, assessed by the integral leukocyte index (the ratio of heterophiles and lymphocytes). Integral leukocyte indices reflected an imbalance of the adaptive response of the blood system in young snakes kept in captivity in relation to adult males and females from natural populations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Elaphe dione</kwd><kwd>Natrix natrix</kwd><kwd>Natrix tessellata</kwd><kwd>лейкоцитарная формула</kwd><kwd>лейкоцитарные индексы</kwd><kwd>иммунный статус</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Elaphe dione</kwd><kwd>Natrix natrix</kwd><kwd>Natrix tessellata</kwd><kwd>WBC (white blood cells)</kwd><kwd>leukocytes indexes</kwd><kwd>immune status</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">Ананьева Н.
