В 2015 году в США был обнаружен цирковирус третьего типа, вызывающий у животных системное воспаление неясной этиологии. Впоследствии были опубликованы данные о выявлении вируса в Азии, Европе и Южной Америке. Проведен анализ литературных данных о современной эпизоотической обстановке по вызванной вирусом третьего типа цирковирусной инфекции за рубежом, а также отражены вопросы клинических и патолого-анатомических проявлений заболевания. В работе представлены результаты молекулярногенетических исследований биоматериалов от свиней из 51 хозяйства 28 регионов Российской Федерации. При исследовании 280  проб биоматериала различного происхождения (органы, ткани, мертворожденные поросята) от домашних свиней с патологией респираторной, репродуктивной и нервной систем, признаками истощения, дерматитами геном цирковируса третьего типа был обнаружен в 11 образцах из 9 хозяйств 5 областей Российской Федерации. Цирковирус третьего типа был выявлен в тканях легких, бронхиальных и средостенных лимфоузлов, селезенки поросят групп доращивания и откорма, взрослых животных и абортированного плода. Положительные пробы по содержанию ДНК цирковируса третьего типа с помощью молекулярных методов (ПЦР, ПЦР в реальном времени) были исследованы на наличие других патогенов. В 6 из 11  проб (55%) были также обнаружены Actinobacillus pleuropneumoniae, Mycoplasma hyorhinis, Streptococcus suis, Haemophilus parasuis, Mycoplasma hyopneumoniae и Pasteurella multocida, а также в одной пробе цирковирус второго типа. Представленные результаты исследований свидетельствуют о возможности смешанной этиологии респираторных патологий и репродуктивных нарушений у обследованных свиней, которые приводят к возникновению широкого спектра клинических признаков. Установлено, что наиболее подвержены заболеванию цирковирусом третьего типа поросята в возрасте доращивания и откорма. Для выявления реального патогенного потенциала цирковируса третьего типа и изучения его распространения на территории Российской Федерации необходимы дальнейшие исследования.</p></abstract><trans-abstract xml:lang="en"><p>Diseases associated with porcine circoviruses (mainly with porcine circovirus type 2) have various manifestations, are common in pigs in countries having well-developed pig industry and responsible for significant economic losses. Porcine circovirus type 3 (PCV-3) causing systemic inflammation of unknown etiology in animals was detected the USA in 2015. Later, data on PCV-3 detection in Asia, Europe and South America were published. Analysis of literature data on current epidemic situation on PCV-3 infection in foreign countries as well as the disease clinical manifestations and postmortem lesions are described. Results of molecular and genetic tests of biomaterials collected from pigs in 51 holdings located in 28 regions of the Russian Federation are presented. A total of 280 samples of biological materials of different types (organs, tissues, stillborn piglets) collected from domestic pigs with respiratory, reproductive and neurological disorders, dermatitis and from emaciated pigs were tested and PCV-3 genome was detected in 11 samples from 9 holdings located in 5 regions of the Russian Federation. Porcine circovirus type 3 was detected in lung, bronchial and mediastinal lymph node, spleen tissues from grower and fattening piglets, adult pigs and aborted fetuses. Samples that were positive for PCV-3 DNA when tested with molecular methods (PCR, real-time PCR) were tested for other pathogens. The following pathogens were also detected in 6 out of 11 samples (55%): Actinobacillus pleuropneumoniae, Mycoplasma hyorhinis, Streptococcus suis, Haemophilus parasuis, Mycoplasma hyopneumoniae and Pasteurella multocida. Porcine circovirus type 2 was detected in one sample. Presented test results are indicative of probable combined etiology of respiratory and reproductive disorders in tested pigs that results in various clinical manifestations. Grower and fattening piglets were found to be the most susceptible to PCV-3-associated disease. Further studies are required for identification of actual PCV-3 pathogenicity and its prevalence in the territory of the Russian Federation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полимеразная цепная реакция</kwd><kwd>цирковирус 3-го типа (ЦВС-3)</kwd><kwd>свиньи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymerase chain reaction</kwd><kwd>porcine circovirus type 3 (PCV-3)</kwd><kwd>pigs</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">Использование аэросила А-300 и фильтров GF/F (GF/C) для очистки фрагментов ДНК, ДНК-плазмид и РНК / О.
