In a double-blind, placebo-controlled study in 10 healthy volunteers, lactulose powder 10 g/day for 26-33 days was an effective food-grade prebiotic (36). Fecal bifidobacteria increased significantly during lactulose intake, with a concomitant decrease in Clostridia.

To understand the role of antibiotics, it is important to understand their effects on the fecal flora. The normal flora consists of a complex bacterial population with 400-500 distinct species of bacteria (table 2a). More than 99% of the total organisms are accounted for by non-sporeforming anaerobic rods [28] the four major species are Bacteroides, bifidobacteria, eubacteria and peptostrepto-cocci [29], Other common species are Escherichia coli, Streptococcus viridans, Streptococcus salivarius and lacto-bacilli. Mette et al. [30] clarified the prevalence of species in fecal flora by listing the four most common anaerobes Bacteroides spp., Eubacterium spp., Bifidobacterium spp. and anaerobic cocci) and three common aerobes E. coli spp., Enterococcus spp. and Lactobacillus spp.) (table 2b).

The relative abundance of bifidobacteria within the human gut decreases with age, even if ecological analyses based on FISH and metagenomic studies estimated that their presence in the adult colon is around 4.3 4.4% of fecal microbes. In adult feces, B. adolescentis and B. catenulatum species were commonly detected, followed...
