Abstract

Abstract : The immunosuppression induced by thermal injury renders the burned victim susceptible to infection. A mouse model was developed to examine the immunosuppression, which was possible to induce even at a minor thermal insult of 6% total body surface area. After induction of the burn (48 hr) a depression of leukocytes in the peripheral blood was found of the burned mice. This depression was due to a reduction in the polymorphonuclear cells. The burned mice were not able to clear a Pseudomonas aeruginosa wound infection, since the infection spread to the blood as compared to mice only infected with P. aeruginosa subcutaneously. The burn model offers an opportunity to study infections under these conditions. The present model can also be used to examine new antibiotics and immune therapy. Our animal model resembling the clinical situation is useful in developing new treatments of burn wound victims. © 2017 by John Wiley & Sons, Inc.
