Mouse Response

• Vaccine Immune Response Type: VO_0000286
• Immune Response: Intranasal immunization with a pDNA mixture coding the four adhesins triggered significant levels of specific serum and mucosal Ig that inhibited S. aureus adhesion to cow mammary gland epithelial cells in vitro. Splenocytes of immunized mice challenged in vitro with S. aureus extracts showed a strong proliferative response (Castagliuolo et al., 2006).
• Efficacy: In non immune mice or mice injected with empty vectors, a large number of bacteria was recovered from the mammary glands. Whereas, in mice immunized with the genetic vaccine coding the four S. aureus adhesins, the amount of bacteria recovered from the mammary glands was significantly decreased (Castagliuolo et al., 2006).
