Effectiveness of Multistrain Probiotic Formulation on Common Infectious Disease Symptoms and Gut Microbiota Modulation in Flu-Vaccinated Healthy Elderly Subjects

Figure 4

Taxa bar plot representing the most representative genera composing the faecal microbiota in elderly subjects identified by V3-V4 16S rRNA amplicon sequencing during the study period (T0-T28-T56). The cumulative relative abundance of specific ASVs belonging to the probiotics or to the placebo groups is shown: each bar represents a study period and each colored box a bacterial taxon. The order from the top to the bottom of each ASVs at the phylum level corresponding to a different colored box represents the percentage of relative abundance of bacteria within the group.
