Figure 1

Composition of chicken microbiota with or without of S. Enteritidis infection. The cecal microbiota in young chickens were dominated by representatives of the family Lachnospiraceae (phylum Firmicutes) followed by Ruminococcaceae (Firmicutes) and Enterobacteriaceae (Proteobacteria). Infection of chickens with S. Enteritidis repeatedly increased representatives of Lactobacillaceae. Panel A, experiment 1, for which the figures were generated by averaging the microbiota composition of all time points i.e. from day 7, 10, 13, 16 and 19. Panel B - experiment 2, in which the luminal and mucus associated microbiota were characterized separately. 1 – Lachnospiraceae, 2 – Ruminococcaceae, 3 – Enterobacteriaceae, 4 – unclassified Clostridiales, 5 – Lactobacillaceae, 6 – Catabacteriaceae, 7 – Clostridiaceae, 8 - Bifidobacteriaceae.
