Exploring the relationship between gut microbial ecology and inflammatory disease: An insight into health and immune function

Table 2 Longitudinal distribution of gut microbes in the human gastrointestinal tract with respect to the pO₂ and pH of different regions

Gastrointestinal tract	Prevalence in human	Prevalence in mouse
Stomach	Cardiac, fundic, body, pylorus, pH-1.5 to 3.5	Fore stomach, body, pylorus, pH-3 to 4
Small intestine	6 m, pH-6.4 to 7.3	350 mm, pH-4.7 to 5.2
Colon	Ascending, transcending and descending colon, pH-6.7	Undivided, No fermentation, pH-4.4 to 5.0
