Karazhas to the study of the epidemiology of opportunistic infections. To solve the upcoming tasks, N.V. Karazhas first of all developed and put into practice methods of serological diagnosis of two opportunistic infections - cytomegalovirus and mycosis pneumocystosis, without which it is impossible to account for the incidence of these infections. Using these methods, she revealed the widespread occurrence of asymptomatic forms of pneumocystosis in Russia, primarily among patients with bronchopulmonary pathology and in persons with immuno-deficient conditions. In asymptomatic cytomegalovirus infection, the possibility of developing manifest forms against the background of immunodeficiency was revealed, and a high probability of nosocomial spread of this infection was shown. Currently, N.V. Karazhas continues to work on studying the epidemiological features of different forms of cytomegalovirus and pneumocystosis, including the combinations with HIV infection, herpesvirus infections in patients with tuberculosis are being studied, and CMI in patients with respiratory tuberculosis is being studied. In addition to her main activities, Natalia Vladimirovna created the Museum of the History of the Gamalei Institute on a voluntary basis.</abstract><kwd-group xml:lang="en"><kwd>history of medicine</kwd><kwd>opportunistic infections</kwd><kwd>epidemiology</kwd><kwd>cytomegalovirus infection</kwd><kwd>serological diagnostics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>история медицины</kwd><kwd>оппортунистические инфекции</kwd><kwd>эпидемиология</kwd><kwd>цитомегаловирусная инфекция</kwd><kwd>серологическая диагностика</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Савинков П.А., Рыбалкина Т.Н., Каражас Н.В. и др.
