Microbial Translocation: from Myth to Mechanism

Abstract

The microbial flora of the normal human gastrointestinal (GI) tract is enormously complex. The number of organisms that normally reside along the mucosal surface stretching from the oropharynx to the rectum exceeds the total number of cells in the human body by a factor of ten [1]. Careful studies of the nature of this flora have shown that it consists of upwards of 600 separate microbial species, each tending to associate with a specific anatomical niche in the GI tract, yet the total population is remarkably stable over time [2]. Under normal circumstances, this flora exists in a symbiotic relationship with the adjacent epithelial cells of the GI mucosa, and remains located on the luminal surface where it prevents colonization by potentially pathogenic organisms [3] and even modulates the immunological activity of epithelial cells of the host [4]. However a variety of pathological conditions can disrupt the relationship between the indigenous flora of the GI tract and the gut epithelium, and organisms can gain entrance to deeper tissues; this process has been termed “bacterial (or more appropriately “microbial”) translocation”.
