Cellular immune responses to amoebic liver abcess in the guinea-pig.
Guinea-pigs infected in the liver with the Biswas strain of Entamoeba histolytica showed no dermal hypersensitivity but showed positive lymphocyte transformation and macrophage-migration inhibition. The time sequence showed an activated response at 4 days after infection, a full response at 8 days when the liver abscesses were resolving and a waning response at 12 days when the abscesses had healed.
