Caecal microbial community of 9-week-old layers, one week after IBV infection. Taxonomic composition is given at the genus level among the different lines, and according to their vaccine status: vaccinated and challenged (V-Ch, n = 48) vs non-vaccinated and challenged (NV-Ch, n = 45). Every bar corresponds to one individual. Only taxons with a mean relative abundance above 2% are displayed.
