Explanation of fields used in the table
| Shorthand | Longhand | Significance |
|---|---|---|
| Coloniser | Colonises lower intestine | Whether the organism can colonise the bowel and/or the lower smaller intestine, at least temporarily. |
| Alt Name | Alternative name | A synonym (homotypic or heterotypic); old name; common name |
| O2 Tolerance | Ability to tolerate oxygen (classified as strictly aerobic, aerobic, facultative anaerobic, microaerobic, aerotolerant, anaerobic or strictly anaerobic). | |
| Spore | Endospore or exospore | Whether the organism produces internal spores, external spores or none. |
| DNA GC (%) | Proportion of GC content in DNA (%) | The percentage of the guanine:cytosine pair in bacterial DNA. |
| Bile Tolerance (%) | Ability to cope with presence of bile | Some bacteria are sensitive to the emulsifying effects of bile, which disrupts membranes, denatures proteins and chelates iron and calcium ions (Urdaneta2017). Evolved commensals (and pathogens) have developed mechanisms to cope with this potentially lethal substance. |
| Temperature Tolerances | Optimum temperature for growth; growth temperature range. | Ability to tolerate and grow at different temperatures. |
| pH Tolerances | Optimum pH for growth; growth pH range. | Ability to tolerate and grow at different pH ranges. |
| Salt Tolerances | Optimum salt (%) for growth; growth salt (%) range. | Ability to tolerate and grow at different salt concentrations (%). |
