Relative abundance of Escherichia/Shigella genus. a Relative abundance trends of fifteen amplicon sequence variants (ASVs) recovered from the broilers’ caeca and associated with the Escherichia/Shigella genus. Each dot represents the relative abundance mean of each ASV per time point. b Escherichia/Shigella relative abundance over time in ESBL-Ec− and ESBL-Ec+ broilers. No differential abundance of Escherichia/Shigella was observed over time between broilers' groups (ANCOM-BC, p > 0.05)
