P.5 box 2: "Concentration of Bacteria in the Colon-The most widely used approach for measuring the bacterial cell density in the colon is by examining bacteria content in stool samples. This assumes that stool samples give adequate representation of colon content. [Investigators] return to this assumption in the discussion. The first such experiments date back to the 1960s and 1970s [refs 20,21]. In those early studies, counting was based on direct microscopic clump counts from diluted stool samples. Later experiments [refs 22,23] used DAPI [4',6-diamidino-2-phenylindole] nucleic acid staining and fluorescent in situ hybridization [FISH] to bacterial 16S RNA. Values are usually reported as bacteria per gram of
dry stool. For [their] calculation, [they] are interested in the bacteria content for the wet rather than dry content of the colon. To move from bacteria/g dry stool to bacteria/g wet stool [they] use the fraction of dry matter as reported in each article. Table 2 reports the values [they] extracted from 14 studies in the literature and translated them to a common basis enabling comparison." See notes beneath table |
