OVA-specific serum IgG1, IgG2a, and IgE levels in OVA-sensitized mice.

<p>Mice were OVA-sensitized as described in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0022004#pone-0022004-g002" target="_blank">Figure 2</a> and treated with PBS and challenged with PBS (OVA/PBS/PBS),,treated with <i>A. baumannii</i> and challenged with OVA (OVA/<i>A. baumannii</i>/OVA), treated with formalin-fixed <i>A. baumanii</i> and challenged with OVA (OVA/ffAb/OVA), or treated with PBS and challenged with OVA (OVA/PBS/OVA). Groups of 5 mice were euthanized five days after i.n. OVA challenge, and serum was collected. The OVA-specific IgG1, IgG2a and IgE levels were measured using ELISA. Each data point represents the mean OD value ± SD of five mice in each group.
