We explored cefditoren (CDN) total and free values of serum concentrations exceeding the MIC (t>MIC) related to efficacy in a mice sepsis model, and the effect of specific gammaglobulins on in-vitro phagocytosis and in-vivo efficacy. %U http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0012041
