    Abstract:
    A biological assay based upon the induction of abscesses in mice injected subcutaneously with Trichomonas vaginalis was shown to be a valid method for comparing the virulence of two isolates of T. vaginalis cultured from two patients, one suffering from severe vaginitis and the other exhibiting only mild disease. The data showed excellent correlation between the physical dimensions of abscesses in mice injected with each trichomonad isolate and the severity of vaginitis produced in the women from whom the isolates were obtained. The assay employed in our study incorporated measurement of the mean abscess volumes from day 1 to day 6 post-inoculation with T. vaginalis. We found that the abscess assay was clearly superior to a murine intraperitoneal assay for virulence evaluation of trichomonad isolates. We then used the murine abscess assay to determine the susceptibility of different strains of mice to infection with a virulent T. vaginalis isolate so as to test whether the genetic constitution of the host would influence the pathogenesis of the disease. BALB/c (H-2d) mice were susceptible to infection with T. vaginalis, but both CBA/CaH (H-2k) and BALB/c-H-2k mice were shown to be resistant. The quantitation of abscess formation in these inbred and congeneic resistant mouse strains demonstrates that the severity of infection with T. vaginalis is governed by genes mapping within the major histocompatibility complex.
