Fig. 4: Selection for intI1 by Ciprofloxacin.

Significant selection for intI1 by ciprofloxacin is seen at concentrations of 15.625 µg/L (p = 0.0634, Gamma GLM) and higher. *Significant positive selection to 90% confidence in comparison to the no antibiotic control. **Significant positive selection to 95% confidence in comparison to the no antibiotic control. n = 5 replicates per concentration. Boxplot follows the Tukey’s representation.
