• We studied the effect of muramyl dipeptide (MDP) on enhancing resistance to local bacterial challenge in starved mice. The challenge consisted of the intramuscular insertion of a suture laden with Klebsiella pneumoniae. Mice that had been pretreated with MDP had a statistically lower rate of bacterial recovery at the site of the challenge, had consistently fewer bacteria in the blood, and had improved short-term survival. By enhancing local bacterial containment, MDP pretreatment of immunocompromised animals reduces the level of bacteremia and subsequent mortality.
