Bacterial composition in human milk samples of healthy mothers and mothers suffering sub-acute mastitis. The bar plot shows average percentage of abundance of the genus-level bacteria (DNA) and active bacteria (RNA) detected in the human milk samples by means of Illumina MiSeq sequencing of the 16S rRNA gene. Controls: DNA, n = 24; RNA, n = 23; SAM_t0: DNA, n = 23; RNA, n = 23; SAM_t1; DNA, n = 19; RNA, n = 19. t0 = samples during the course of the symptoms; t1 = samples after symptoms disappeared. Due to the small sample size (n = 3), acute mastitis samples were not included in the bar plots. Created in R software v 3.5.1 (2018–07-02) (https://www.R-project.org).
