A comparison of antibody titres in mouse uterine fluid after immunization by several routes, and the effect of the uterus on antibody titres in vaginal fluid.
Measurements of specific antibody titres in uterine fluid of mice immunized by different routes indicated that two immunizations in the pelvic presacral space using aluminium hydroxide as adjuvant was a simple and effective way to elicit a significant IgA and IgG response. Higher IgA and IgG titres were produced in uterine fluid by subcutaneous immunization with antigen in Freund's complete adjuvant followed by intravaginal boosting without adjuvant, but this immunization involved both a toxic adjuvant and repeated applications of large doses of antigen in the vagina. Intragastric immunization produced an IgA response in the uterus but no IgG. Local intravaginal priming and boosting with large doses of antigen without adjuvant produced an IgA response in uterine fluid, but was less effective for IgG and was inefficient in terms of time and the amount of antigen used. Hysterectomy reduced the concentration of specific IgA in vaginal fluid of immunized mice to no more than 5% of normal, indicating that most of the IgA in vaginal fluid originates in the uterus. In contrast, IgG titres were not significantly different in hysterectomized and intact mice. IgA titres in vaginal fluid were at least partly restored to normal levels in sham-hysterectomized mice.
