Four products derived from Staphylococcus aureus cultures were partially purified and tested for inhibitory activity against staphylococcal phage. Phage inhibition, a specific stable phenomenon, was concentration dependent. All inhibitory products contained carbohydrate and amino acids, the most active (phage 73 lysate product) having a high carbohydrate content. Galactose, glucosamine, five or six amino acids, and possibly 3-O-methylglucose and a uronic acid were found as components in all active preparations. However, the exact nature of the active material remains undetermined.
从金黄色葡萄球菌培养物中提取的四种产物经过部分纯化，并测试了其对葡萄球菌噬菌体的抑制活性。噬菌体抑制是一种特定的稳定现象，呈浓度依赖性。所有抑制性产物均含有碳水化合物和氨基酸，活性最高的（噬菌体73裂解产物）碳水化合物含量很高。在所有活性制剂中均发现半乳糖、氨基葡萄糖、五种或六种氨基酸，以及可能的3-O-甲基葡萄糖和一种糖醛酸作为成分。然而，活性物质的确切性质仍未确定。
