Abstract
Summary
CF-1 female mice 4 weeks of age were exposed 6 days a week to 0.5, 1 or 2 r γ radiation/day. After 4 to 39 weeks exposure they were challenged by intraperitoneal inoculation of graded doses of Pseudomonas aeruginosa. No detectable effect on host resistance to this experimental bacterial infection was demonstrated.
The authors express their grateful appreciation to the following members of Depts. of Medicine and Radiology, Univ. of Chicago: Dr. Leon O. Jacobson for use of the cobalt-60 room in Argonne Cancer Research Hosp. USAEC: Lawrence H. Lanzl for assistance in planning arrangements and for the dosimetric determinations; and George A. Sacher, Argonne Nat. Lab., Lemont, Ill. for many helpful suggestions.
