Fig 2. Effects of roemerine on the growth of bacteria colonies.
Roemerine, vancomycin and oxacillin were added to cell cultures containing S. aureus ATCC29213, MRSA XJ75302, Mu50, or LAC, respectively, with addition of an equal volume of sterile water as a control. Aliquots of each culture were collected at 0, 3, 6, 12, and 24 h, and were then diluted and inoculated on solid agar. The number of colony-forming units (CFUs) was calculated from the number of colonies growing on plates, and the data are the means for three replicates. CON, control; ROE, roemerine; VAN, vancomycin; OXA, oxacillin. *P<0.05, **P<0.01, ***P<0.001 versus Control.
