После 10-часового прогревания при температуре 98 °С из 50 % проб такого молока выделены микобактерии туберкулеза с дефектной клеточной стенкой (cell wall deficient – CWD).Штаммы CWD МБТ выдерживали пятичасовое прогревание при температуре 98 °С.При нагревании закономерно изменялась морфология клеток, возрастала их кислотоустойчивость вплоть до появления полностью кислотоустойчивых клеток. Посев прогретых суспензий на специальную питательную среду во всех случаях дал рост CWD МБТ, не отличавшихся от исходных культур. Это подтверждает уникальную термическую устойчивость МБТ и указывает на то, что даже такое экстремальное термическое воздействие не решает проблему биобезопасности молока.</p></abstract><trans-abstract xml:lang="en"><p>The DNA of Mycobacterium tuberculosis (MBT) was found in the milk of cows that did not reacted to tuberculin. After 10 hours of warming up at 98 °С cell wall deficiency (CWD) mycobacterium tuberculosis was isolated from 50% of samples of such milk.Strains of CWD MBT withstood 5 hour warming up at 98 °С.The morphology of cells naturally changed during warming, their acid-fastness increased up to the appearance of completely acid-fast cells. Sowing of warmed suspensions on a special nutrient medium in all cases gave growth of CWD MBT which did not differ from the initial strains, which confirms the unique thermal stability of MBT and indicates that even such extreme thermal exposure does not solve the problem of biosafety of milk.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>туберкулез крупного рогатого скота</kwd><kwd>скрытая туберкулезная инфекция</kwd><kwd>микобактерии туберкулеза с дефектной клеточной стенкой</kwd></kwd-group><kwd-group xml:lang="en"><kwd>bovine tuberculosis</kwd><kwd>latent tuberculosis</kwd><kwd>cell wall deficient tuberculosis mycobacteria</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">Ferran, J.
