Primary source [7] abstract: "Escherichia coli was isolated from more than 2300 non-domesticated vertebrate hosts living in Australia." Primary source [12] abstract: "Fecal samples from 1032 infants at 1 month of age, who were recruited from the KOALA Birth Cohort Study in the Netherlands, were subjected to quantitative real-time polymerase chain reaction assays for the enumeration of bifidobacteria, Escherichia coli, Clostridium difficile, Bacteroides fragilis group, lactobacilli, and total bacterial counts. Information on potential determinants of the gut microbiotic composition was collected with repeated questionnaires. The associations between these factors and the selected gut bacteria were analyzed with univariate and multivariate analyses." |

P.207 right column bottom paragraph: "In humans, the prevalence is more than 90% [primary sources 11,12], but it is only 56% in wild mammals, 23% in birds and 10% in reptiles [primary source 7]. " From Wikipedia-"Prevalence in epidemiology is the proportion of a particular population found to be affected by a medical condition (typically a disease or a risk factor such as smoking or seat-belt use)." |
