FIG. 3.
Nasopharyngeal colonization by strain TN106.P2 in BALB/c mice immunized with rCBD derived from GST fusion proteins. (A) Bacterial colonization in mice vaccinated with rCBDP860295. (B) Bacterial colonization in mice vaccinated with rCBDN187. (C) Bacterial colonization in mice vaccinated with rCBDTN106. In panel A, an asterisk indicates significant difference from D-PBS control and two asterisks indicates significant difference from D-PBS plus CT-E29H and D-PBS plus vaccine buffer controls. In panels B and C, an asterisk indicates significant difference from D-PBS control and two asterisks indicates significant difference from D-PBS plus CT-E29H control. The x axis represents the detection limit of the assay, and each bar represents the standard error of the means.
