mechanism of acquired immunity in experimental giardiasis

ABSTRACT

Giardia-spontaneously cured mice were rendered resistant to challenge infection. This was documented by the decreased cyst excretion rate comparable to the control ones. Endoxan and irradiation treatment caused a breakdown in both humoral and cellular immunity. Immune-depressed mice were more susceptible to Giardia infection, thus proving the active role of antibodies and cell-mediated immune response in giardiasis
