The four chimeric recombinant antigens CBD-CFP10, CBD-ESAT6, ESAT6-CFP10 and CBD-P38 contained aminoacid sequences of full-size proteins ESAT6, CFP10 and matured protein P38 of M. tuberculosis, joined with aminoacid sequences of cellulose bind domain of endogluconase A (CBD) from Cellumonas fimi have been obtained by gene engineering methods. Recombinant proteins were purified by affine chromatography in column with Ni-NTA-sepharose 6В-CL and as PPDN-3 were used for detection of their antigenic activity in indirect ELISA for TB serological diagnostics. The sera from patients with lung tuberculosis (n = 321), from persons who had professional contacts with TB patients (n = 42), from healthy blood donors (n = 366) and from patients with lung diseases of non-TB etiology were tested. It was detected that there was positive correlation between antibodies level for all studied antigens compared by pair. It has been demonstrated that although antigens were different by antigenic and immunobiological characteristics they add each other in the content of antigenic diagnostics compositions. Thus, all these antigens can be used in the test kits for serological diagnostics of TB. Using of these antigens will allow to detect persons infected by TB and patients with active tuberculosis. </p></abstract><trans-abstract xml:lang="ru"><p/><p/><p/><p><bold>Резюме</bold>. Методами генной инженерии получено четыре химерных рекомбинантных антигена: CBD-CFP10, CBD-ESAT6, ESAT6-CFP10 и CBD-P38, содержащих аминокислотные последовательности полноразмерных белков ESAT6 и CFP10 и зрелого белка P38 M. tuberculosis, состыкованные с аминокислотной последовательностью целлюлозосвязывающего домена эндоглюконазы А (CBD) из Cellumonas fimi. Рекомбинантные белки были очищены методом аффинной хроматографии на колонке с Ni-NTA-сефарозе 6В-CL и, наряду с PPDN-3, были использованы для определения их антигенной активности в непрямом варианте ИФА при серодиагностике ТБ. В работе исследовались сыворотки, полученные от больных туберкулезом легких (n = 321), от лиц, имеющих профессиональный контакт с больными ТБ (n = 42), от здоровых доноров (n = 366) и от больных заболеваниями легких нетуберкулезной этиологии (n = 68). Было выявлено наличие достоверной положительной корреляции между уровнями антител против всех исследованных антигенов, сравниваемых попарно. Показано, что антигены существенно отличаются по своим антигенным и иммунобиологическим свойствам, но дополняют друг друга в составе антигенных диагностических композиций и могут найти применение в тест-системах для серодиагностики ТБ. Использование данных антигенов позволит выявлять лиц, инфицированных ТБ, а также выявлять больных с активным ТБ. </p></trans-abstract><kwd-group xml:lang="en"><kwd>M. tuberculosis</kwd><kwd>E. coli</kwd><kwd>synthetic genes</kwd><kwd>cloning</kwd><kwd>expression</kwd><kwd>P38</kwd><kwd>ESAT6</kwd><kwd>CFP10</kwd><kwd>antigenic characteristics</kwd><kwd>blood sera.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>tuberculosis</kwd><kwd>E. coli</kwd><kwd>синтетические гены</kwd><kwd>клонирование</kwd><kwd>экспрессия</kwd><kwd>P38</kwd><kwd>ESAT6</kwd><kwd>CFP10</kwd><kwd>антигенные свойства</kwd><kwd>сыворотки.</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
