title: Evaluation of a vaccine for control of streptococcic lymphadenitis of swine.
abstract: Three tirals were conducted to evaluate the use of a vaccine for control of streptococcic lymphadenitis of swine. Clinically normal swine were vaccinated orally, according to the manufacturer's instructions. Unvaccinated controls and the vaccinated pigs were subsequently inoculated with a virulent strain of the etiologic agent, group E Streptococcus, serotype IV. At necropsy, 47 of the 51 vaccinated pigs (92.1%) were free of cervical abscesses, whereas 20 of the 21 control pigs (95.2%) developed cervical abscesses.
