| Method |
Primary source abstract: "[Investigators] have applied fluorescence in situ hybridization of pre-16S rRNA to Escherichia coli cells growing in vitro in extracts from two different compartments of the mouse intestine: the caecal mucus layer, where E. coli grew rapidly, and the contents of the caecum, which supported much slower bacterial growth." |
| Comments |
P.208 left column top paragraph: "Although the concentrations of these sugars in the intestine are low [ref 17], E. coli maximizes its growth by using micro-aerobic and anaerobic respiration in the intestine [ref 18]. This results in a 30 minute generation time in vitro on intestinal mucus [primary source] compared with 40–80 minutes in the intestines of streptomycin-treated mice, in which the cells in the luminal content are static [BNID 116915 ref 14], and 120 minutes when the mice are 'conventionalized' by removing the streptomycin and feeding them with mouse caecal content [ref 20]. This change in growth rate in the presence of other species illustrates that E. coli competes with those other species." |
