Bactericidal Activity of Serum for Klebsiella Rhinoscleromatis: Studies on Serum from a Patient with Rhinoscleroma and Sera Deficient in Antibody or Complement North, M. E. and Newton, C.

Experiments with C2-deficient and hypogammaglobulinaemic human sera suggested that killing depended on activation of the classical complement pathway, although the alternative pathway probably amplified the effect. Serum from a patient with active rhinoscleroma, and another cured of the disease, showed normal killing., language=, type=
