Comments P.207 right column top paragraph: "Although the anaerobic bacteria in the bowel outnumber E. coli by 100/1 to 10,000/1 (primary source), E. coli is the predominant aerobic organism in the gastrointestinal tract." Primary source p.432 right column top paragraph: "Thus, obligate anaerobes (e.g. Bacteroidis fragilis) are 100- to 1000- fold more numerous than facultative anaerobes (e.g. Escherichia coli and other coliforms), the organisms commonly cultured as indicators of human fecal contamination."
