What is the typical colony count of flora in the stomach?

Explanation:
The stomach normally hosts only a small number of bacteria because the highly acidic environment and rapid turnover limit microbial growth. A typical gastric flora count is on the order of 10^3 CFU per milliliter, so 1000 CFU/mL reflects that low, baseline level of colonization. Counts as low as 10 CFU/mL would be unrealistically sparse for resident flora, while much higher numbers like 10^5 or 10^8 CFU/mL would indicate heavy colonization, often due to altered acidity or disease. In healthy individuals, around 10^3 CFU/mL captures the usual situation.
