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.
