Материалы и методы. В работе использованы флуоресцентный штамм Y. pestis КМ2083 – производный природного штамма филогенетической линии 4.ANT античного биовара основного подвида – и культура нематод, выделенные на одной территории Горно-Алтайского очага чумы. Систематическую принадлежность нематод определяли по участку гена 18S рРНК, филогенетический анализ проводили методом Maximum Likelihood на основе модели Tamura-Nei в программе Mega 7.0. Взаимодействие штамма Y. pestis КМ2083 и нематод изучали при культивировании на твердой агаровой среде NGM. Наблюдение за нематодами осуществляли с использованием микроскопов Stemi-2000C (Carl Zeiss, Германия) и Axio Imager Z2 (Carl Zeiss, Германия). Результаты и обсуждение. Установлено, что использованные в работе нематоды из ГорноАлтайского высокогорного очага чумы относятся к роду Panagrolaimus. Культивирование нематод на газоне штамма Y. pestis основного подвида античного биовара филогенетической линии 4.ANT в течение 24 ч не привело к сокращению продолжительности жизни нематод по сравнению с контрольным образцом, что свидетельствует об отсутствии токсичности использованного штамма по отношению к нематодам Panagrolaimus. На кутикуле нематод отмечено образование биопленки в области половых органов и хвоста, в пищеварительном тракте наблюдали скопления флуоресцентных клеток возбудителя чумы. Полученные данные могут свидетельствовать о способности нематод к переносу возбудителя чумы в почвенном биоценозе.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to study interaction of Yersinia pestis with soil nematodes isolated on the territory of the Gorno-Altai high-mountain plague focus. Materials and methods. We used the fluorescent Y. pestis strain KM2083, a derivative of the natural strain of the 4.ANT phylogenetic line, the antique biovar of the main subspecies, and a nematode culture isolated in the same area of the Gorno-Altai plague focus. The taxonomy of nematodes was determined by the region of the 18S rRNA gene; phylogenetic analysis was performed using the Maximum Likelihood method based on the Tamura-Nei model in the Mega 7.0 software. The interaction of the Y. pestis KM2083 strain and the nematodes was studied during cultivation on a solid NGM agar medium. Nematodes were observed using microscopes Stemi-2000C (Carl Zeiss, Germany) and Axio Imager Z2 (Carl Zeiss, Germany). Results and discussion. It has been established that the nematodes from the Gorno-Altai high-mountain plague focus used in the work belong to the genus Panagrolaimus. Cultivation of nematodes on the lawn of the Y. pestis strain of the main subspecies of antique biovar, the 4.ANT phylogenetic line for 24 hours did not lead to a reduction in the lifespan of nematodes compared to the control sample, which indicates the absence of toxicity of the used strain towards Panagrolaimus nematodes. On the cuticle of nematodes, the formation of a biofilm in the genital area and tail has been noted, and accumulations of fluorescent cells of the plague pathogen observed in the digestive tract. The data obtained can indicate the ability of nematodes to carry the plague pathogen in the soil biocoenosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>возбудитель чумы</kwd><kwd>Горно-Алтайский высокогорный очаг чумы</kwd><kwd>почвенные нематоды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>plague agent</kwd><kwd>Gorno-Altai high-mountain plague focus</kwd><kwd>soil nematodes</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">Goodrich-Blair H., Clarke D.J.
