E-cigarette aerosols did not affect the growth patterns of S. mutans. (A) Overnight cultures of S. mutans were diluted 1:10 into e-cig aerosol-pretreated medium. Optical density was measured every 5 min over the course of 8 h. The average was calculated and plotted for OD₆₀₀ (top) and log₂ transform (bottom). (B) Slopes for linear regression of S. mutans are presented based on the derivative of the log₂ transform. Data are representative of one biological replicate (n = 3) repeated at least twice.
