[Humoral immunity aspects of meningococcal infection. I. A method of performing and the characteristics of the immune bacteriolysis reaction].
Immune bacteriolysis test with meningococcus, group A, was used for the purpose of serum antibody study. Meningococcus cultures with a bright orange fluorescence of the colonies in oblique illumination (the I type) proved to possess the greatest lysability. Guinea pig serum sorbed with meningococcus suspension was found to be the best source of the complement. Sera obtained after 1 to 3 days of rabbit immunization, containing mostly IgM antibodies, had the greatest bactericidal capacity. Only those fractions which contained IgM possessed bactericidal activity in the hyperimmune rabbit sera with a high IgG antibody concentration. No lytic activity was displayed against meningococcus by unfractionated hyperimmune sera.
