Nippostrongylus brasiliensis infection in the rat: effects of surgical removal of Peyer's patches, mesenteric lymph nodes and spleen.

The influence of the surgical removal of Peyer's patches, mesenteric lymph nodes and spleen has been examined on the host response to Nippostrongylus brasiliensis infection in the rat. In animals subjected to these procedures, no effects were observed on whole blood or plasma histamine levels, peripheral blood leucocytosis or reaginic antibody levels, intestinal mast cell numbers or histamine content, nor on faecal egg output.
