Abstract
The increasing antimicrobial drug resistance of Salmonella typhimurium has been a major public health problem in many countries. The type III secretion system (TTSS) of S typhimurium is an attractive target for the development of new antibiotics against this bacterium. In this study, we determined whether berberrubine derived from Berberis vulgaris could inhibit TTSS expression in S typhimurium. Berberrubine inhibited TTSS expression at a concentration of 60.9 µM. Additionally, TTSS-related mRNA expression of sipA, sipB, sopA, and sopD was downregulated in the presence of berberrubine. Collectively, we anticipate that berberrubine can be a useful tool to prevent the risks of infections caused by pathogenic bacteria.
