[Pathomorphology of chronization and outcomes of experimental mycoplasma-viral pneumonia].
Pathomorphology of pneumonia induced by successive contamination of the Syrian hamsters with a pathogenic strain of Mycoplasma pneumoniae and an influenza virus A/PR8/34 as well as after contamination with an influenza virus against the background of a previous administration of the mycoplasma membrane fractions was studied. Mixed Mycoplasma-viral infection results in a tumor-like bronchiolar epithelium proliferation having a morphological similarity with bronchiolo-alveolar or acinar carcinoma, influenza virus infection against the background of a previous administration of protein fractions of mycoplasma membranes resulted in a chronization of pneumonia with development of several types of morphological changes: reversible tumour-like proliferation of the bronchiolo-alveolar epithelium, "inflammatory" pseudotumours and sarcoid-like granulomas.
