Study of antibodies directed against antigens of the gut epithelium of Schistosoma mansoni using an immunofluorescence reaction. IV. Blocking action on immunity of an IgM monoclonal antibody

The inhibitory effect on immunity is demonstrated by passive transfer experiments in mice. It can be shown in a secondary infection with Schistosoma mansoni and also in primary infection. The results indicate that blocking activity probably interfers with non specific immunity mechanisms.
