Abstract

Intravenous injection of anti-asialo GM 1 antibody into mice infected with Trichinella pseudospiralis resulted in rapid acute illness or death accompanied by a dramatic rise in hematocrit values in these animals. The described antibody-induced changes were reversible by intravenous infusion of Hanks' balanced salt solution (HBSS). These effects were not seen in uninfected mice or in Trichinella spiralis-infected mice injected with anti-asialo GM 1 antibody. Viability of T. spiralis or T. pseudospiralis infective L1 larvae, both isolated worms and those housed in muscle, was unaffected by exposure to anti-asialo GM 1 antibody and complement. Infectivity of larvae of T. pseudospiralis decreased significantly following exposure to anti-asialo GM 1 antibody. Release of protein by T. pseudospiralis infective L1 larvae during incubation in the presence of anti-asialo GM 1 antibody was significantly greater than that released by worms incubated in normal rabbit serum or HBSS. Protein released by infective L1 larvae of T. pseudospiralis was identified as Trichinella excretory/secretory antigens by immunoblot. Intravenous injection of T. pseudospiralis excretory/secretory products resulted in anaphylaxis in T. pseudospiralis-infected mice but not in uninfected or T. spiralis-infected mice. Excretory/secretory product-induced anaphylactoid response also was reversible by the intravenous injection of HBSS or by injection of an antihistamine. Significantly higher levels of total IgE were observed in sera from mice infected with T. pseudospiralis compared to uninfected or T. spiralis-infected mice. Binding of anti-asialo GM 1 antibody to the surface of T. pseudospiralis muscle larvae induced release of excretory/secretory antigen by the parasite. This event led to degranulation of mast cells armed during the course of infection by IgE, leading to an anaphylactoid response in the host.
