Functional morphology and microflora in chicken intestine after infection by Escherichia coli

The authors estimate the effect of pathogenic strains of Escherichia coli on morphology of digestion organs and also on composition and number of microflora in chicken intestine. It was shown, that experimental infection of chicken by E. coli result in qualitative and quantitative changes of intestine microflora which are typical for dysbacteriosis (an increase in the number of bacteria with low lactase activity or hemolytic properties and a decrease in the number of lactose positive bacteria among the strains of E. coli and Bifidobacterium ).
