[Formation and persistence of latex-agglutination-inhibiting IgG- and IgM-antibodies in rabbits inoculated with poliomyelitis, Coxsackie and encephalomyocarditis viruses (author's transl)].

The formation and presistence of virus specific IgG- and IgM-antibodies produced in rabbits after a single dose of poliomyelitisvirus, coxsackievirus or encephalomyocarditisvirus were tested comparatively by latex-agglutination-inhibition test, hemagglutination-inhibition test and neutralization test. The animals were immunized either intravenously alone or with Freund's complete adjuvant. The IgM-antibodies were only detectable for a short time by the three tests. In the IgG-fraction and in the unfractionated serum the neutralizing antibodies persisted without any loss in titer during the period observed, whereas the latex-agglutination-inhibiting and hemagglutination-inhibiting antibodies showed a significant decrease. The hemagglutination-inhibiting antibodies required 23 weeks (Figure 5), the latex-agglutination-inhibiting antibodies 7 weeks (without Freund's complete adjuvant; Figure 1 and 3) or about 16 weeks (with Freund's complete adjuvant; Figure 2, 4 and 5) respectively to decline to 25% of their maximum titer.
