Pneumonia due to Mycoplasma in gnotobiotic mice. IV. Localization and identification of Mycoplasma pulmonis in the bronchi of infected gnotobiotic mice by immunofluorescence and by light microscopy.

Abstract:

:The model of pneumonia produced by intranasal inoculation of Mycoplasma pulmonis in gnotobiotic mice provided the opportunity to study the localization and identification of the infecting organisms in the tissues by immunofluorescence techniques. Frozen sections of pneumonic mouse lung were fixed in acetone, layered with rabbit anti-M. pulmonis serum, washed, layered again with fluorescein-isothiocyanate-labeled goat anti-rabbit globulin, washed again, and examined by fluorescence microscopy. A bright line of fluorescence was seen at the bronchial epithelial surface, usually in a continuous layer. Occasional masses of fluorescence were seen in the polymorphonuclear leukocytic exudate in the bronchial lumen. Sections of tissues fixed in Helle's or 10% Formalin fixatives and stained with hematoxylin and eosin were reviewed by light microscopy and revealed a zone of blue-staining material composed of tiny coccoid bodies in the same locations at the bronchial epithelial surface as in the immunofluorescent preparations and in previously reported electron microscope studies.
