Lactobacillus elicits a 'Marmite effect' on the chicken cecal microbiome

Microbial diversity of 1572 cecal samples from chicken. a Relative abundance of the most abundant genera by chicken breeds. Number on top of bars represent the number of sequencing samples for each breed, note that certain samples are pooled from multiple chicken cecal samples (see supplementary table 1). Only taxa present at greater than 1% were included. b Principal-coordinate analysis plot of unweighted UniFrac distances coloured according to hypervariable region. Numbers in brackets are the number of samples sequenced using each hypervariable regio
