Influence of coffee (Coffea arabica) and galacto-oligosaccharide consumption on intestinal microbiota and the host responses
After mice consumed coffee and GOS, their intestines were sampled, and the bacterial counts were measured with quantitative RT-PCR. Results showed that GOS consumption significantly increased Although Escherichia coli and Clostridium spp. A bacterial growth inhibition assay was also conducted, and the results showed that E. coli growth was inhibited only by a coffee agar. In conclusion, coffee has antibiotic effects, and GOS significantly decreased E. coli
