Experimental infection with the protozoan parasite Encephalitozoon cuniculi induced an augmentation of pulmonary natural killer cell (NK) activity in C57BL/6 mice. Enhanced clearance of 51Cr-labelled YAC-1 lymphoma cells peaked on day 4 of infection and returned to normal levels by the tenth day of infection. Infected mice also demonstrated heightened resistance to pulmonary tumor formation compared to uninfected control mice following challenge with lung-homing B16F10 melanoma cells.
