The evolution of the classes of specific immunoglobulins (IgG, IgM, IgA, IgE) of 40 cases of human trichinosis was followed over a nine month period by means of an indirect immunofluorescence test (IF) and ELISA. Specific IgG and IgM appear between 4 and 6 weeks after infection and were still demonstrable after 9 months (respectively in 87.5% and 38.5% of the patients with IF, in 85% and 87.5% with ELISA). Specific IgA were mainly seen on the 2nd month and specific IgE were detected in 37.5% of the patients on the 4th month. In this outbreak, specific antibodies seem to appear later than in a second outbreak observed a few weeks later.
