Increased susceptibility to ornithosis virus, administered by aerosol, was observed in white mice pretreated with x-rays. A shortening of the incubation period, observed in the irradiated, infected animals, depends on x- ray dose, virus dose and time interval between irradiation and infection. Ornithosis virus is retained longer and reaches higher titres in the lungs, liver and spleen of irradiated animals.
