Table 1: Identification of differentially expressed proteins of carbapenem-resistant strain (RS 307) of A. baumannii under iron overload growth condition with reference to that of iron-free condition. Differential expression is shown as fold change (p-value e 0.05). Negative sign of fold change showed that it is down-regulated in the presence of iron or over-expressed in the absence of iron.
