В работе показана эффективность применения аминоэтилэтиленимина в качестве инактиванта вируса ящура. Определены скорость снижения титра инфекционности при выбранных параметрах процесса инактивации, влияние аминоэтилэтиленимина на стабильность вируса в процессе инактивации и на иммуногенность вакцин после хранения при температуре 2–8 °С. Представлен метод вычисления пятидесятипроцентной инактивирующей кон- центрации аминоэтилэтиленимина (К50), позволяющей определять качественную характеристику вируссодержащей суспензии, сравнивать активность инактивантов и их способность обеспечивать авирулентность препарата в заданный промежуток времени. В результате проведенных исследований было установлено, что значение К50 для неочищенной и очищенной вируссодержащих суспензий было одинаковым – 0,0045%, а уровень безопасности после 12 ч инактивации составил одну ТЦД50 в 109 –1011 л вируссодержащей суспензии. Также было выявлено, что увеличение времени инактивации в два раза повысило вирулицидную активность аминоэтилэтиленимина: для типа О – в 1,8 раза, для типа А – в 2,4 раза. В то же время очистка от клеточного дебриса на процесс инактивации не оказывала существенного влияния. Аминоэтилэтиленимин не разрушает 146S частицы вируса, что и было подтверждено при исследовании иммуногенной активности вакцин в процессе хранения. Таким образом, аминоэтилэтиленимин, выпускаемый в виде 15%-го водного раствора российской фирмой ООО «Биохимресурс» (г. Владимир), соответствует высоким стандартам качества. При исследовании иммуногенности эмульсионной бивалентной противоящурной вакцины для крупного рогатого скота в остром опыте установили, что активность препарата составила 10,08 защитных доз в прививном объеме 2 см3.</p></abstract><trans-abstract xml:lang="en"><p>Inactivation is the loss by a virus of ability to reproduce and infect susceptible animals while retaining its antigenic properties. In this paper, the effectiveness of aminoethylethanolamine when used as an FMDV inactivant is shown. The inactivation rates under selected parameters, effect of aminoethylethanolamine on virus stability during inactivation and on vaccine immunogenicity after storage at 2–8 °С were determined. The method for calculation of 50% aminoethylethanolamine inactivating concentration (IC50) which enables to determine quality parameters of the virus-containing suspension, to compare the inactivating agent activities and their ability to ensure the vaccine innocuity within the given period of time is presented. It was established that IC50 for purified and non-purified virus-containing suspensions was identical (0.0045%), and its safety after 12 h of inactivation was one TCID50 per 109–1011 L of the virus containing suspension. It was also found that double increase in inactivation time increased the virucidal activity of aminoethylethanolamine by a factor of 1.8 for serotype O and 2.4 for serotype A. At the same time, the removal of cell debris had no significant effect on the inactivation process. Aminoethylethanolamine does not destroy 146S virus particles and it was confirmed by immunogenicity testing of the vaccines during storage. This means that 15% aqueous solution of aminoethylethanolamine, manufactured by Russian Company OOO “BIOKHIMRESURS” (Vladimir) complies with high quality standards. Immunogenicity test of bivalent FMD vaccine for cattle by challenging demonstrated that its potency was 10.08 protective doses per 2 cm3 of the vaccination dose.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вирус ящура</kwd><kwd>вирулицидная активность</kwd><kwd>инактивант</kwd><kwd>вакцина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>foot and mouth disease virus</kwd><kwd>virucidal activity</kwd><kwd>inactivating agent</kwd><kwd>vaccine</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств ФГБУ «ВНИИЗЖ» в рамках тематики научно-исследовательских работ «Ветеринарное благополучие».</funding-statement><funding-statement xml:lang="en">The study was funded by the FGBI “ARRIAH” within the framework of “Veterinary Welfare” research work.</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">Сергеев В.
