[Experimental sensitizing activity of Neisseria perflava].

In experiments conducted on guinea pigs the sensitizing activity of Neisseria perflava isolated from the mucous membranes of the bronchi of patients with infectious asthma was studied. A possibility of reproducing active skin anaphylaxis after Ovary and of the contraction-test of the tracheal-chain by the neisseria antigens was shown. Neisseria perflava was found to possess a greater sensitizing activity than Staphylococcus aureus and Klebsiella pneumoniae inhabiting the bronchi of patients with infectious asthma.
