The pathogen Pasteurella multocida (as one of the most frequent pathogenic agents involved in both isolated and combined radiation-biology lesions of agricultural animals) was used as a model of a biological agent to reproduce experimental biological research. We employed the \u201cChinchilla\u201d rabbits of 2.5\u20133.0\u2009kg body weight as a biological model for doing combined radiation Pasteurella lesion. When determining the optimal model of combined radiation-biology (Pasteurella) lesion, we consider that in the joint action of various pathological agents on the organism, there is a synergistic effect of explosion agents, previously specifying minimal doses of external \u03b3-radiation and pasteurellosis pathogen that in the joint action of nonfatal doses would be lethal. The first stage of the experiments determined the minimal doses of gamma rays and pasteurellosis pathogen that in joint action causes combined radiation-biology pathology. We examined 66 rabbits divided into 11 groups of 6 animals each to determine minimal doses of infectious agent-pasteurellosis pathogen. The animals of the first 9 groups were given subcutaneously Pasteurella species at doses 1\u00b7109, 1\u00b7108, 1\u00b7107, 1\u00b7106, 1\u00b7105, 1\u00b7104, 1\u00b7103, 1\u00b7102, and 1\u00b7101 of microbial cells per animal of 0.3\u2009ml suspension in volume; the 10th group of animals were given saline solution; the 11th served as a biological control group. In determining the minimal doses of gamma rays, we conducted experimental tests on 36 rabbits, which have been exposed to external \u03b3-radiation in the \u201cPUMA\u201d system with a 137Cs radiation source of the exposure dose of 5.38\u2009R\/min at doses 2.0, 4.0, 6.0, 8.0, 10, and 12\u2009Gy. To specify the optimal model of radiation-pasteurellosis lesion, we used the rabbits subjected to a combined radiation-biology effect using minimal doses of gamma rays and pasteurellosis agent, leading to a lethal effect during their complex action. The researches revealed that 50% of the death of rabbits infected with pasteurellosis occurs using Pasteurella at a dose of 3.7\u00b7104 microbial cells per kilogram (LD50\u2009=\u20093.7\u2219104\u2009m.c.\/kg), and 50% of radiation death in rabbits occurs when irradiated their gamma rays at a dose of 8.0\u2009Gy (LD50\u2009=\u20098.0\u2009Gy). The combined effect of nonlethal doses of the studied agents in the indicated doses on rabbits led to the aggravation of the course of radiation and pasteurellosis infection, causing the death of animals from combined radiation-pasteurellosis pathology. The model combined radiation-pasteurellosis disease ran its course rapidly, and the animals died 3 to 6 days after the onset. The autopsy of the animals that died from acute radiation-pasteurellosis pathogen had found swelling of the subcutaneous tissue in the pharynx and intermaxillary space of the neck, hyperemia, lymphoid nodular hyperplasia, numerous hemorrhages on the serous and mucous membranes and in the tissues of the parenchymal organs, serous or serous-fibrinous exudate, and in the chest and abdominal regions, pulmonary edema. The research stated that gamma radiation of rabbits at a dose of 8.0\u2009Gy conducted before exposure with Pasteurella at LD50 (3.7\u00b7104\u2009m.c.\/kg) declined the course of the pasteurellosis process, facilitated its generalization, and fastened the death of animals. Combined radiation-pasteurellosis infection ran its course rapidly, and the animals died within 3 to 6 days after the onset of the disease. The autopsy showed the pathologicoanatomic factors of the acute pasteurellosis: swelling of the subcutaneous tissue, purulent-catarrhal bronchopneumonitis, and pulmonary edema.<\/jats:p>","DOI":"10.1155\/2022\/9433032","type":"journal-article","created":{"date-parts":[[2022,9,9]],"date-time":"2022-09-09T02:35:09Z","timestamp":1662690909000},"page":"1-7","source":"Crossref","is-referenced-by-count":1,"title":["Development of an Optimal Model of Combined Radiation and Biological Lesions"],"prefix":"10.1155","volume":"2022","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3832-883X","authenticated-orcid":true,"given":"Timur R.","family":"Gaynutdinov","sequence":"first","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Konstantin N.","family":"Vagin","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yagafar M.","family":"Kurbangaleev","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kamil T.","family":"Ushmukhametov","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Farit Kh","family":"Kalimullin","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanentina A.","family":"Guryanova","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilnar R.","family":"Yunusov","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksey V.","family":"Frolov","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fanil R.","family":"Vafin","sequence":"additional","affiliation":[{"name":"Federal Center for Toxicological, Radiation and Biological Safety, Nauchnyi Gorodok-2, Kazan 420075, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1126\/sciadv.aay5478"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1080\/08998280.2020.1725731"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1517\/17460441.2015.1023290"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1080\/17460441.2019.1591364"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1088\/1755-1315\/723\/4\/042008"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1080\/09553002.2020.1793020"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.18632\/aging.103815"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1007\/s13205-017-0925-0"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.3201\/eid2502.180641"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.3201\/eid2406.171998"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1128\/MMBR.00014-19"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1089\/vbz.2019.2558"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.21608\/kvmj.2016.108683"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1080\/20008686.2019.1604064"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-017-14601-8"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1186\/s12917-018-1565-2"},{"key":"17","first-page":"14328","article-title":"Study of radioprotective properties of E.Coli metabolites","volume":"8","author":"A.
