Commercially available disc paper used for antibiotic sensitivity tests was shown to contain an unidentified, water-soluble agent inhibitory to Bacillus stearothermophilus which gave false positive results in an antimicrobial assay for milk. The agent however, was found to be inactive against a range of common pathogenic bacteria. It was easily removed by washing the discs in distilled water before use.
用于抗生素敏感性测试的市售圆纸片被证明含有一种未知的水溶性物质，该物质对嗜热脂肪芽孢杆菌有抑制作用，在牛奶抗菌检测中会产生假阳性结果。然而，该物质对一系列常见病原菌无活性。在使用前用蒸馏水清洗圆纸片即可轻松去除该物质。
