Abstract

The bark of Cinnamomum bejolghota (Buch.-Ham.) Sweet (C. bejolghota) is widely used as medicine to treat bacterial diarrhea in Myanmar. We previously reported that the bark extract of C. bejolghota significantly inhibited secretion effector proteins of the type three secretion system (T3SS) in Salmonella. This study is designed to investigate the anti-virulence potential of the C. bejolghota bark extract against Salmonella Typhimuriumin in in vivo and in vitro experiments. The results suggested that the polar fraction Fr.M1 inhibited the secretion of effector proteins SipA, SipB, SipC and SipD without affecting bacteria growth and the translocation of SipC into MDA-MB-231 cells. In addition, Fr.M1 alleviated inflammatory symptoms of mice in Salmonella-infected mouse model. Overall, the results provide evidence for medicinal usage of C. bejolghota bark to treat diarrhea in Myanmar.
