Streptococcus ferus is a mutans-like streptococcus originally isolated from wild rats fed with sugar cane. Taxonomically, this species has not been studied extensively. Ten Gram-positive coccal strains, isolated from the tonsils and nasal conchae of piglets, were identified as S. ferus by 16S rDNA sequencing, tRNA-intergenic spacer length polymorphism analysis (tDNA-PCR), whole-cell protein profiling using SDS-PAGE, G+C content determination and extensive biochemical testing. In all these tests, the type strain of S. ferus (LMG 16520T), from a rat, was included. The results of the tests are described and an emended species description is presented.
野生链球菌是一种变形链球菌样链球菌，最初从喂食甘蔗的野生大鼠中分离出来。在分类学上，该物种尚未得到广泛研究。通过16S rDNA测序、tRNA基因间隔区长度多态性分析（tDNA-PCR）、使用SDS-PAGE的全细胞蛋白质谱分析、G+C含量测定和广泛的生化测试，从仔猪扁桃体和鼻甲中分离出的10株革兰氏阳性球菌菌株被鉴定为野生链球菌。在所有这些测试中，均纳入了来自大鼠的野生链球菌模式菌株（LMG 16520T）。描述了测试结果并给出了修订后的物种描述。
