title: [Pathological anatomy of pneumonia in Mycoplasma pneumoniae infection in children].
abstract: A total of 43 section observations on acute respiratory viral diseases in children aged between 13 days to 13 years are described.  Using the direct and indirect fluorescent antibody test in 11 observations M. pneumoniae antigen was detected; in 4 observations this antigen was represented as monoantigen, and in 7 observations--in association with viruses of influenza, parainfluenza and adenovirus.  The characteristic features of mycoplasma pneumoniae were noted; very high blood filling of vessels of all calibres with the involvement of the system of microcirculation of the lungs, with phenomana of pronounced dilatation of the capillary net and with a tendency to thrombo-formation; diffuse lesions (dystrophic and inflammatory changes) of large and small bronchi and bronchioles; plasmocellular reaction in interstitia of the lungs, perbronchial follicles and bifurcated lymphatic nodes; the presence of M. pneumoniae antigen in histological sections of the lungs.  The author thinks it advisable to discard the term "M. pneumoniae-pneumonia" and replace it by "M. pneumoniae-infection" with predominent localization of the process in the lungs.
