RESISTANCE TO PNEUMOCOCCUS INFECTION IN RABBITS FOLLOWING IMMUNIZING INJECTIONS OF HEAT-KILLED PNEUMOCOCCUS SUSPENSIONS.
The degree and duration of the active resistance against pneumococcus infection have been determined in rabbits which received intravenous injections of a heat-killed suspension of pneumococci of the three principal types. The resistance induced by the immunization procedure varied in degree and in duration with each type of Pneumococcus.
