| 内容記述 | Objective: Streptococcus (S.) pyogenes is common cause of acute tonsillitis. Lipoteichoic acid (LTA), which is a common constitute of the cell surface of most gram positive bacteria, is known to act as a substance of bacterial site for adherence to epithelium and antiserum to LTA is reported to inhibit bacterial attachment to epithelial cells in vitro. Cholera toxin subunit B (CT-B) is known to be a mucosal adjuvant. The purpose of this study is to investigate whether intranasal immunization with LTA and CT-B may be a possible candidate for vaccine formulation. Methods: Six-week-old male BALB/c mice were assigned to 3 experimental groups, mice immunized with LTA and CT-B, with LTA alone and with phosphate buffered saline (PBS) as a control. Immunizations were performed intranasally every 2 days for 2 weeks in every group. At the 21 days after immunization, sera, pharyngeal washings and pharyngeal epithelial cells were taken. The levels of serum IgG and pharyngeal IgA antibodies to LTA were measured by enzyme-linked immunosorbent assay (ELISA). The adherence rates of S. pyogenes pretreated by pharyngeal washings to pharyngeal epithelial cells from the mice were determined by in vitro adherence assay. Results: The serum anti-LTA IgG antibody levels of either mice immunized with LTA and CT-B or mice immunized with LTA alone were significantly higher than those of mice administered with PBS alone. The pharyngeal anti-LTA IgA antibody levels of the mice immunized with LTA and CT-B were significantly higher than those of either mice with LTA alone or mice with PBS alone. The streptococcal adherence rates to pharyngeal epithelial cells were significantly decreased by pretreatment with pharyngeal washings from the mice immunized with LTA and CT-B as compared to pretreatment with those from either mice with PBS or mice with LTA alone. Conclusions: These data shows that intranasal immunization with LTA nd CT-B evokes a good pharyngeal IgA response as well as systemic IgG response to LTA and inhibits streptococcal adherence to pharyngeal epithelial cells, suggesting that intranasal immunization with LTA and CT-B may be an effective approach to prevent streptococcal tonsillitis. | |||||||||||
