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

An attempt was made of detecting antigenic similarity beyween the fraction of microsomes of the tissues of human broncho-pulmonary apparatus and the cells of microbes of human respiratory tract. Cross reactions of antimocrosomal sera were studied in the complement fixation test with Neisseria perflava and Klebsiella pneumoniae. Fixation of antibacterial antibodies and antibodies against the microsomal fraction of the lung tissues was studied on the sections of the lung tissues ahd human bronchi. The presence in the microsomal fraction of tissues of human bronchopulmonary apparatus of the antigens cross reacting with antimicrobial sera was demonstrated.
