FIGURE 2.

Differentially abundant bacteria associated to lactation stage. Differentially abundant OTUs between the early (n = 33) and late (n = 43) groups. (A) Fold change (FC log₂) in relative abundance of significantly different (DESeq2) OTUs between groups and their normalized mean counts. Species are grouped by phylum. The dashed red line indicates “infinite” fold change, where an OTU had detectable counts in samples from only a single group. (B) An illustration of species-level differentially abundant bacteria between milk of early (blue) and late (red) lactation stages. Raw abundance is represented. The complete OTU table including relative abundance, annotation, count distribution, blast statistics, alternative database hits, and sequences are provided in Supplementary File 1.
