Probiotic potential of Escherichia coli ŽP for the gut microbiota of chickens
The effect of oral administration of Escherichia coli ŽP strain carrying a conjugative plasmid encoding the colicin E7 on the composition of the intestinal chyme microbiota of chickens was studied. It was shown that E. coli ŽP was present in the chyme of chickens 6-24 days of age in all experimental...

In the microbiota of the control group (not administered with the ŽP strain) the Firmicutes phylum, as well as Proteobacteria (E. coli), Actinobacteria (Eubacterium spp.) and, to a lesser extent, Bacteroidetes were found.
