[Mycoplasma hominis as an agent of respiratory tract diseases].

Respiratory organs of newborn rats inoculated intranasally with broth culture of Myc. hominis were studied by the histological, histochemical and immunofluorescence methods. Tracheitis and development of purulent and interstitial pneumonia with a hemorrhagic component were revealed 24 hours after the infection. These changes were observed up to the 7th day of the experiment. At the same period a specific fluorescence of the Myc. hominis antigen was found by the antibody fluorescent test. The present study pointed to the pathogenicity of the Myc. hominis for the respiratory tract of the newborn rats.
