Erinacine C protects indicator strains Lactococcus lactis and S. sanguinis from killing by S. mutans. Overnight cultures of S. mutans UA159 in THBY (with and without MIP or erinacine C) were spotted on THBY plates and incubated for 4–6 h. Then, the plates were overlaid with exponential phase cultures of indicator strains grown in THBY and suspended in soft agar (0.7%). After 20 h of incubation (37 °C, 5% CO2) the area of zone of inhibition was measured. The image is a compilation of single technical replicate (cropped from the incubated agar plates) for the indicator strains and compound treatment after 20 h incubation
