Normal flora in the duodenum are both tolerant to acidic environments and similar to the microflora in the stomach. This is because the stomach and duodenum are both part of the upper gastrointestinal tract and have similar environmental conditions. However, unlike the stomach, the duodenum also has alkaline secretions from the pancreas and bile duct, so the normal flora in the duodenum must also be able to tolerate alkaline environments.
