Abstract

An immunofluorescent study has been made of IgG, IgM and IgA in the stomach of uninfected minimal disease pigs and pigs infected with a single dose of 100,000 third stage infective Hyostrongylus rubidus larvae. Immunoglobulin-positive cells were present in both uninfected and infected animals. In infected animals both IgM and IgA immunocytes increased in numbers following infection and the numbers remained raised during the histotropic phase of worm development. No increase in IgG immunocyte numbers was noticed throughout the course of infection (100 days).
