Immunotherapeutic effect of the lactobacillus vaccine, Solco Trichovac, in trichomoniasis is not mediated by antibodies cross reacting with Trichomonas vaginalis.

    According to the producers of the lactobacillus vaccine, Solco Trichovac, its therapeutic effect in trichomoniasis is achieved by antibodies that are induced by the vaccination and cross react with Trichomonas vaginalis. Common antigens of Lactobacillus acidophilus from Solco Trichovac vaccine and T vaginalis were therefore sought by three different seroreactions. Immune serum against Lacidophilus obtained by vaccinating two healthy human volunteers and two rabbits with the original Solco Trichovac vaccine, as well as hyperimmune rabbit antiserum to T vaginalis, were tested with each of the two micro-organisms. No evidence of antigenic similarity between L acidophilus and T vaginalis was obtained with either serum in any of the three serological tests. A non-specific immunostimulatory effect therefore seems to be a more probable explanation of the mode of action of Solco Trichovac vaccine.
