The reliability of the bacitracin inhibition test to differentiate between 125 Lancefield group A and 122 non-group A beta-haemolytic streptococci was studied. Bacitracin discs containing 0-02, 0-04, or 0-1 international units and the conditions recommended by both the Association of Clinical Pathologists and the Federal Drug Administration for routine sensitivity testing were used. The results suggest that the presence or absence of a zone of inhibition around a 0-04 unit disc can be used routinely for the presumptive identification of group A streptococci and that a specific zone size can be used for reading the test only with a 0-1 unit disc.
研究了杆菌肽抑制试验对125株A群兰斯菲尔德链球菌和122株非A群β溶血性链球菌进行鉴别的可靠性。使用了含0.02、0.04或0.1国际单位的杆菌肽纸片，以及临床病理学家协会和联邦药物管理局推荐的常规药敏试验条件。结果表明，0.04单位纸片周围有无抑菌圈可常规用于A群链球菌的初步鉴定，只有0.1单位纸片可使用特定的抑菌圈大小来判读试验结果。
