Bacteroides fragilis is not typically found in the stomach; it is primarily located in the human colon as part of the normal gut microbiota. While it can occasionally be present in the stomach under certain conditions, such as in cases of dysbiosis or gastrointestinal disease, its primary habitat is the lower gastrointestinal tract. Its presence in other areas, like the stomach, can indicate an imbalance in the gut flora.
Bacteroides fragilis typically has seven copies of the 16S rRNA gene in its genome. Each copy of this gene plays a crucial role in the identification and classification of the bacterium.
