Figure 6.

Bacterial genera with increased relative abundance before or after radiotherapy plotted in a LEfSe. The plot bars inside the red box (a) correspond to the overall taxa that are significantly abundant either in pre-RT or mid-RT samples. No significant taxa were specified to the post-RT groups since no differences in β-diversity were observed between mid and one-month post-radiation. The not assigned bar corresponds to the family Pasteurellaceae, of which no specific genus could be identified. Data point visualization is shown here for the top five identified genera, including the mid-RT biomarkers, namely Streptococcus (b), Gemella (d) and the top pre-RT taxa Neisseria (c), Capnocytophaga (e) and Leptotrichia (f).
