Previous studies have shown that attenuated salmonellae utilized as vaccine vectors engender strong immune responses; however, balancing immunogenicity with reactogenicity remains problematic. Recent work in other bacteria has shown that photochemical treatment of DNA excision repair mutants (ΔuvrAB) renders organisms “killed but metabolically active” (KBMA). Here, we extend this concept toSalmonella typhimurium.A strain of attenuatedS. typhimuriumpreviously evaluated in human volunteers was further deleted foruvrABgenes and designated CKS362. Photochemical treatment of CKS362 resulted in significant inactivation. These KBMA organisms were metabolically active as shown by radioactive methionine incorporation and lactate dehydrogenase activity. In mice inoculated intraperitoneally, KBMA CKS362 was markedly less reactogenic and stimulated a humoral immune equivalent to its live counterpart. Because the parental strain has previously been found to elicit strong immune responses toSalmonellaantigens, we propose CKS362 as a prototype strain to test the immunogenicity of KBMA organisms in humans.
