Cross protection of mice and swine given live-organism vaccine against challenge exposure with strains of Erysipelothrix rhusiopathiae representing ten serovars.


Mice and swine vaccinated (subcutaneous inoculation) with live acriflavine-fast attenuated Erysipelothrix rhusiopathiae, strain Koganei 65-0.15 (serovar 2), were challenge exposed with 10 strains of E rhusiopathiae pathogenic for swine; the latter strains comprised serovars 9 and 10 and other previously undetermined. Vaccinated mice did not die after they were challenge exposed (subcutaneous inoculation) with serovars 4, 6, 7, 8, 9, 10, 15, 16, or N, but vaccinated mice challenge exposed with strain 2553 (serovar 20) had 30% mortality. Nonvaccinated control mice died after they were challenge exposed with all serovars tested. One of 2 vaccinated swine challenge exposed (intradermal inoculation) with each of strains 911 (serovar 8), 2179 (serovar 10), or 2553 developed localized urticarial lesion at the site of intradermal inoculation. Vaccinated swine challenge exposed with serovars 4, 6, 7, 9, 15, 16, or N did not have clinical signs of acute swine erysipelas. Nonvaccinated control swine developed localized lesions at the site of intradermal challenge inoculation.
