[Localization in cells of Neisseria perflava and Klebsiella pneumoniae of antigens in common (cross-reacting) with tissues of the human bronchopulmonary apparatus].

A study was made of localization in the cells of Neisseria perflava and Klebsiella pneumoniae of antigens common with the tissues of the human broncho-pulmonary apparatus. A study was made of cross reactions of some structures of Neisseria perflava and Klebsiella pneumoniae cells (capsule, walls, cytoplasmic structure fraction, hyaloplasm) in the complement fixation test with antilung sera. Antigens cross reacting with the antilung sera were localized not only in the surface structures (walls) of bacterial cells, but also in the "deep" components (cytoplasm fraction rich in ribonucleoproteids) of the microbe.
