O-acetylation is necessary for an effective protective vaccine response in a murine pyelonephritis model. Female CD-1 mice (20/group) were immunized three times with 0.01 mcg of O-acetylated (native) CP5-CRM197 with AlPO4, de-O-acetylated CP5-CRM197 with AlPO4, or AlPO4 alone, then challenged with S. aureus. Bacterial burden in the kidneys was determined two days after challenge.
