Nineteen strains of nutritionally variant streptococci (NVS) were tested for bacteriolytic activity and for their production of and sensitivity to streptococcal bacteriocinlike inhibitory substances (BLIS). None appeared to produce BLIS. An inverse relationship was found between the sensitivity to BLIS and the production of bacteriolytic activity against Micrococcus luteus. All but one of the 14 Streptococcus defectivus isolates were sensitive to the BLIS of S. pyogenes P5, and these isolates were nonlytic. The five S. adjacens isolates were not sensitive to any BLIS tested, and all of these isolates displayed bacteriolytic activity. Sensitivity to the BLIS of S. agalactiae P3 separated the nonlytic S. defectivus strains into two categories.
对19株营养变异型链球菌（NVS）进行了溶菌活性检测，以及它们对链球菌类细菌素抑制物质（BLIS）的产生和敏感性检测。似乎没有菌株产生BLIS。发现对BLIS的敏感性与对藤黄微球菌的溶菌活性产生之间呈负相关。14株缺陷链球菌分离株中，除1株外，其余均对化脓性链球菌P5的BLIS敏感，且这些分离株无溶菌活性。5株毗邻链球菌分离株对所检测的任何BLIS均不敏感，且所有这些分离株均表现出溶菌活性。对无乳链球菌P3的BLIS的敏感性将无溶菌活性的缺陷链球菌菌株分为两类。
