Полученные результаты демонстрируют выраженные антигенные свойства рекомбинантных белков и подтверждают перспективность созданных штаммов-продуцентов для получения стандартизированных антигенных препаратов, пригодных для использования в ИФА-тест-системах диагностики микоплазмозов сельскохозяйственных животных.</p></abstract><trans-abstract xml:lang="en"><p>The article describes production of recombinant strains-producers of Escherichia coli synthesizing recombinant proteins of M. bovis and M. hyopneumoniae and evaluation of antigenic properties of membrane proteins synthesized by them.
