Quantitative assessment of protection in experimental syphilis.
Protection in experimental rabbit syphilis has been previously assessed by lesion development following intradermal challenge with Treponema pallidum. We have recently reported that passive immunization using monoclonal antibody M131 conveys partial protection as evidenced by significant lesion delays following intradermal challenge. To determine whether such delays in time to lesion appearance...
متن کاملQuantitative microhaemagglutination assay for Treponema pallidum antibodies in experimental syphilis.
The quantitative microhaemagglutination assay for Treponema pallidum antibodies (MHA-TP) was studies in 52 untreated and treated rabbits with experimental syphilis. Rabbits with incubating experimental syphilis were cured or inadequately treated with penicillin G and some cured rabbits were later reinfected. MHA-TP conversion occurred within 45 days in untreated rabbits. Titres reached peak lev...

1. The size of the dose of the infecting material exerts an appreciable effect upon the duration of the incubation period in experimental syphilis of the rabbit. Other things being equal, the larger the dose the shorter is the incubation period. 2. The size of the inoculum was not found to exercise any marked effect upon the course of the disease as a whole. 3. In individual rabbits inoculated ...
متن کاملExperimental Syphilis in the Rabbit
In a series of more than 200 rabbits in which generalized lesions were observed following local inoculation with Treponema pallidum, there were a number of animals in which characteristic lesions were noted upon mucous membranes or along mucocutaneous borders. These lesions were distributed with about equal frequency between the nose or nasolacrimal system and the eyelids on the one hand, and t...
