Common Trends and Contradictions

The microbial characteristics of infants presented above are summarized in Figure 1. Although some variability exists depending upon the study, there are relatively clear trends evident. The most consistent trends associated with allergy are low numbers of bifidobacteria and high numbers of S. aureus and certain species of coliforms and clostridia. It should be pointed out that there are several aspects of these studies that complicate their interpretation. A fundamental downfall is the evaluation of intestinal microbiota by use of the feces, which may only be indicative of the composition of the microbial community in the lower bowel (52,53). Notably, it has been shown that the proportional quantities of specific strains in the colonic mucosa may differ from those in the feces (54). Moreover, the studies on fecal microbiota reveal little with respect to the composition of the small intestine, which immunologically may be more relevant than the large intestine. Another significant deficiency in these studies is the lack of more detailed characterization, especially at the species and strain level. It is well known that bacterial properties, including their immunological effects, vary between bacterial species
