Fig. 3

Titer of three different soiling conditions from 0 to 16 h. Lines are not the result of any regression but help to visualize trends in the data. Solid lines are between points in which all replicates were above the detection limit. Dashed lines indicate the next point had a replicate at or below the detection limit. Each point represents the geometric mean of two technical replicates and two biological replicates (n = 4). Error bars represent the standard deviation. Asterisks indicate at least one replicate was at or below the detection limit
