The SCV subpopulation expands more slowly in the presence of gentamicin. S. aureus SH1000 was inoculated into TSB with or without gentamicin (Gent), and the total number of CFU and SCV CFU was determined over time (t) (shown in hours). Data were split into 2 graphs (0 to 8 h [A and C]; 0 to 72 h [B and D]) to improve resolution and highlight growth dynamics during the early and late stages of culture. Data points represent the averages of 8 independent cultures, and error bars represent the standard deviations of the means. Those data points from gentamicin-grown cultures that are significantly different (P ≤ 0.05) from the corresponding values in the gentamicin-negative cultures are represented by black symbols.
