SUPPRESSION OF THE FIRST ATTACK WITH SUBSEQUENT RELAPSE: AN IMMUNE PHENOMENON IN EXPERIMENTAL RELAPSING FEVER

In five splenectomized squirrels and chipmunks which were reinoculated with a strain of Spironema recurrentis which had previously been present in their blood, the first attack was entirely suppressed because the animals were immune to the strain of spirochetes inoculated; but after the interval which usually occurred between attacks, a relapse ensued, in which the strain of spirochetes present in the blood was different from the strain inoculated.
