У части больных животных зарегистрировали полный комплекс ярко выраженных симптомов, характерных для «классической» болезни слизистых оболочек крупного рогатого скота: эрозии и язвы на носовом зеркальце и языке, выделение пены из ротовой полости, серозные выделения из носа, геморрагическое воспаление и выраженные продольные эрозии на слизистой пищевода, сычуга и кишечника. Коровы абортировали на разных стадиях стельности. Коэффициент плодотворного осеменения снизился до 20%. Течение болезни осложнилось вовлечением в инфекционный процесс вируса герпеса крупного рогатого скота 4-го типа, бактерий семейства Pasteurellaceae и Clostridium spp. Геном BVDV-3 обнаружили в широком спектре внутренних органов абортированных плодов, телят и взрослых животных. По данным секвенирования возбудитель отнесли к субтипу 3а. Филогенетический анализ участка 5'-нетранслируемой области генома вируса (5'-UTR) показал близкое его родство со штаммами, выделенными в Италии и Бразилии, большинство из которых ранее идентифицированы как контаминанты эмбриональной сыворотки и живых вакцин против вирусных инфекций крупного рогатого скота. В настоящее время средства специфической профилактики против инфекции, вызванной BVDV-3, не разработаны, поэтому необходимы обновление и совершенствование методов диагностики, оптимизация противоэпизоотических мероприятий для недопущения распространения вирулентных штаммов возбудителя, контроль безопасности используемых вакцин.</p></abstract><trans-abstract xml:lang="en"><p>An outbreak of infection caused by Pestivirus H (virus of bovine viral diarrhea – mucosal disease of the third kind, BVDV-3) in a dairy farm with high morbidity and mortality in animals of different ages is described. In some sick animals a full complex of pronounced symptoms characteristic of "classical" bovine mucosal disease was registered: erosions and ulcers on the nasal mirror and tongue, foaming from the mouth, serous discharge from the nose, hemorrhagic inflammation and pronounced longitudinal erosions on the mucosa of the esophagus, rennet stomach and intestine. Cows miscarried at different stages of pregnancy. The coefficient of effective insemination decreased to 20%. The course of the disease was complicated by the involvement of the bovine herpes virus type 4, bacteria of the family Pasteurellaceae and Clostridium spp. in the infectious process. The BVDV-3 genome was found in a wide range of internal organs of aborted fetuses, calves, and adult animals. According to sequencing data, the pathogen was classified as subtype 3a. Phylogenetic analysis of the 5'-untranslated region of the virus genome (5'-UTR) showed its close relationship to the strains isolated in Italy and Brazil, most of which were previously identified as contaminants of fetal bovine serum and live vaccines against viral infections of cattle. No specific prophylaxis against BVDV-3 infection has been developed at this time, therefore, it is necessary to update and improve diagnostic methods, optimize control measures to prevent the spread of virulent strains of the pathogen, and control the safety of the vaccines used.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крупный рогатый скот</kwd><kwd>болезнь слизистых оболочек</kwd><kwd>Pestivirus H</kwd><kwd>ПЦР</kwd><kwd>филогенетический анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cattle</kwd><kwd>pestivirus H</kwd><kwd>mucosal disease</kwd><kwd>PCR</kwd><kwd>phylogenetic analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда, грант № 23-26-00006 «Генетическая изменчивость и разнообразие пестивирусов крупного рогатого скота, основные риски заноса новых генетических вариантов на территорию Российской Федерации».</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Russian Science Foundation, grant No. 23-26-00006 "Genetic variability and diversity of pestiviruses in cattle, the main risks of introducing new genetic variants into the territory of the Russian Federation"</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Глотов А.Г., Глотова Т.И., Нефедченко А.В., Котенева С.В.
