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.
进行了三项试验以评估一种疫苗用于控制猪链球菌性淋巴结炎的效果。根据制造商的说明，对临床正常的猪进行口服疫苗接种。随后，未接种疫苗的对照组和接种疫苗的猪均接种了致病因子E群链球菌IV型的强毒株。尸检时，51头接种疫苗的猪中有47头（92.1%）没有颈部脓肿，而21头对照猪中有20头（95.2%）出现了颈部脓肿。
