Brucellosis is an important bacterial zoonotic infection worldwide responsible for economic losses in livestock industries which represents a considerable and increasing public health burden. The disease is caused by Brucella which possess the ability to invade and replicate within phagocytes and may result to chronic infection, leading to difficulty in medical therapy of the disease. The treatment for brucellosis employs conventional principles that have been applied for a long time and a combination of antibiotics is currently used due to low efficacy of monotherapies. However, vital effects with respect to health and safety are neglected. Nevertheless, the preventive methods and treatments for brucellosis using traditional medicine have not yet been thoroughly studied, hence, alternative therapies such as the use of natural plant extracts as traditional medicine that are safe, efficient and economical should be explored in order to identify candidates that eliminate complications due to brucellosis. Coptis chinensis Franch (Huanglian) is a traditional Chinese medicinal herb and its extract has been known to possess strong antibacterial activity. In this study, the antibacterial effects of C. chinensis Franch extracts, and the major components of the herb namely berberine and palmatine, were investigated on B. abortus. The C. chinensis Franch ethanol extracts (CCFE) showed bactericidal effects at 1,000 μg/ml concentration and berberine at 100 μg/ml concentration. However, C. chinensis Franch and its components did not affect invasion and intracellular growth of B. abortus in RAW 264.7 cells. In conclusion, C. chinensis Franch ethanol extracts, water extract and its major components such as berberine and palmatine would be a beneficial antimicrobial agent without affecting phagocytic pathway within macrophages, and further study for the precise mechanisms of antibacterial effect would be necessary.
