Figure 1.
Microbiota composition in the inoculum and caeca of inoculated and control chicks. Real time PCR was used to quantify probiotic strains in complex populations. The inoculum was dominated by Bacteroides caecicola, Bacteroides plebeius, Megasphaera stantonii and Sutterella massiliensis (Panel A). Ratios calculated only for the probiotic strains showed that composition of the inoculum only partially influenced caecal colonisation (Panel B). Used probiotic strains were completely absent from the caeca of control chicks (Panel C).
