Sixteen kinds of pathogenic bacteria, including Escherichia, Salmonella, Corynebacterium, Neisseria, Streptococcus, Staphylococcus, Diplococcus, Pseudomonas and Vibrio, showed full growth in media containing 5〜100μg/ml of thiamine propyldisulfide. It may be concluded that thiamine propyldisulfide has no effect on the growth of bacteria.
