一个新种，丹毒丝菌扁桃体，提出无毒丹毒丝菌菌株血清型7，这是经常分离出的扁桃体表面健康的猪。该种在形态学和生物化学上与迄今为止表征的丹毒丝菌rhusiopathiae菌株无法区分。7株E.属于血清型7的扁桃体对猪是无毒的，除了菌株T-334，其在接种部位诱导局部荨麻疹病变。小鼠半数致死量范围为1.0 ~ 6.9 × 105 CFU。急诊血清型2（6株）、6（1株）、11（1株）、12（1株）和16（1株）的rhusiopathiae菌株皮内接种后引起全身或局部荨麻疹病变，血清型12的菌株T-312除外，其在小鼠中显示50%致死剂量值≤2.5 × 10 CFU。E.扁桃体是36至40摩尔%鸟嘌呤加胞嘧啶。该物种的菌株与E. rhusiopathiae（ATCC 19414）。E.扁桃体是T-305 T（ATCC 43339）。
A new species, Erysipelothrix tonsillae, is proposed for avirulent Erysipelothrix strains of serotype 7, which is frequently isolated from tonsils of apparently healthy pigs. This species is morphologically and biochemically indistinguishable from the Erysipelothrix rhusiopathiae strains characterized to date. Seven strains of E. tonsillae that belonged to serotype 7 were avirulent for swine, except for strain T-334, which induced a local urticarial lesion at the site of inoculation. The 50% lethal dose values in mice ranged from 1.0 CFU to 6.9 × 105CFU. The E. rhusiopathiae strains belonging to serotypes 2 (six strains), 6 (one strain), 11 (one strain), 12 (one strain), and 16 (one strain) induced generalized or local urticarial lesions after intradermal inoculation, except for strain T-312 of serotype 12, which showed 50% lethal dose values of ≤2.5 × 10 CFU in mice. The deoxyribonucleic acid base composition of E. tonsillae is 36 to 40 mol% guanine plus cytosine. Strains of this species have little deoxyribonucleic acid homology (15 to 43%) with the type strain of E. rhusiopathiae (ATCC 19414). The type strain of E. tonsillae is T-305T(ATCC 43339).
