Figure 3: Bacterial infection is alleviated by moxibustion. (a) Mice were injected intraperitoneally with 10 LD50 Staphylococcus aureus as an acute bacterial model. At 1 h later, mice were untreated or administered moxibustion as indicated. The parallel tests without bacterial infection were performed following the same procedures. Survival was monitored for 48 h after moxibustion ( mice/group) and the log-rank test was performed for the survival curve. , primed group versus 30 min moxibustion group. (b) Once mice died or were sacrificed at 48 h after moxibustion, peritoneal fluids were collected immediately and plated on LB agar to measure the activity of bacterial colony formation. .
