E. E.  aIge production in infections with helminth parasites.  c1976  aLive worn parasites selectively but non-specifically stimulate heterologous antigen primed IgE responses. The evidence suggests that it may be this non-specific IgE response "per se" which leads to the great elevation of total serum IgE. The latter is about by the proliferation of IgE B cells and their differentiation into IgE producing plasma cells. T cells are required for this to occur and the present evidence suggests that parasite specific T cells produce a non-specific IgE stimulating factor in additionto having a parasite specific IgE helper effect.  aAnimal parasites and pests  aHelminths  aImmunology  aNematode infections  aParasitology  aRuminants  aHelminto  aImunologia  aParasitologia  aRuminante  aNematodeos  tImmunologygv. 4, p. 529-532, 1976.
