The growth of secondary immunodeficiency in the population and the increasing role of atypical pathogens against this background have set new challenges for doctors and researchers. Against this background, pneumonia becomes severe and protracted. Diagnosis of atypical pathogens such as Chlamydophila pneumoniae, Mycoplasma pneumoniae (M. pneumoniae), Legionella pneumophila is particularly difficult. Currently, there are no uniform standards for the diagnosis of these pathogens, and the available data are only advisory in nature.

Currently, tuberculosis remains one of the leading causes of death among infectious diseases worldwide. About 3 million people die from tuberculosis every year in the world, and in developing countries one out of every 5 deaths is associated with tuberculosis. But even in developed countries, tuberculosis has again become a serious problem in severe epidemic conditions, 50 - 52% of tuberculosis patients are detected in medical institutions of the general medical network when patients address complaints characteristic of inflammation of the bronchopulmonary system. Moreover, the majority of patients complain of an acute onset of the disease, cough with sputum, fever, weakness, and changes in the X-ray.
