С их помощью в ИФА исследовано 152 культуры Bactec с микобактериальным и немикобактериальным ростом от больных с заболеваниями легких.</p></sec><sec><title>Результаты</title><p>Результаты. При обработке КС протеиназой К (prK) содержание белка снижается в 10 раз, при гидролизе NaOH – более чем в 30 раз. В иммуноблоттинге отмечается сужение спектра распознаваемых антигенов сыворотками гипериммунных мышей (по сравнению с цельными КС), что свидетельствует о снижении их иммуногенности. Модификация КС M. tuberculosis дезавуирует антиген 54 кДа, на который развивается сильный ответ IgG1-подкласса.</p><p>Диагностическая эффективность в ИФА с культурами Bactec возрастает при использовании иммуноглобулинов, полученных против антигенов, обработанных протеиназой К ‒ 79,14% (Pr.A) и 86,68% (Pr.G), при сравнении с иммуноглобулинами против исходного препарата ‒ 70,69% (Pr.A) и 69,11% (Pr.G). Специфичность значительно возрастает при использовании IgG1-антител после иммунизации КС обработанными prK (71,92% против 25,93% в исходном препарате). Таким образом, идентифицированы новые антигены M. tuberculosis, против них созданы новые антительные препараты для диагностики в микробиологических культурах.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The objective</title><p>The objective: using double-site enzyme immunoassay (ELISA) to evaluate the specificity of the antigens of digestive and chemically modified cell walls (CW) of M. tuberculosis.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. Hyperimmune sera of mice were obtained against modified CW antigens; immunoglobulins of different subclasses were isolated from them. With their help, 152 Bactec cultures with mycobacterial and non-mycobacterial growth from patients with lung diseases were tested by ELISA.</p></sec><sec><title>Results</title><p>Results. When CW was treated with proteinase K (prK), the protein content decreased by 10 times, and upon hydrolysis of NaOH, by more than 30 times. In immunoblotting, there was a narrowing of the spectrum of recognized antigens by the sera of hyperimmune mice (compared with whole CW), which indicated a decrease in their immunogenicity. Modification of WC of M. tuberculosis disavows 54 kDa antigen, causing a strong IgG1 subclass response.</p><p>Diagnostic efficacy in ELISA with Bactec cultures increases with the use of immunoglobulins obtained against antigens treated with proteinase K – 79.14% (Pr.A) and 86.68% (Pr.G), when compared with immunoglobulins against the original drug – 70.69% (Pr.A) and 69.11% (Pr.G). Specificity increases significantly when using IgG1 antibodies after immunization with CW treated with prK (71.92% versus 25.93% in the initial preparation). Thus, new antigens of M. tuberculosis were identified, new antibody preparations for diagnosis in microbiological cultures were created against them.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>моноклональные антитела</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>микобактериальные антигены</kwd><kwd>двусайтовый ИФА</kwd><kwd>иммуноблоттинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>monoclonal antibodies</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>mycobacterial antigens</kwd><kwd>two-site ELISA</kwd><kwd>immunoblotting</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">Авдиенко В.
