过去一般认为人类食物中毒型肠炎杆菌属(沙门氏菌属)感染主要累及小肠,但其所致腹泻的病理生理学材料目前还很少。大部份可靠资料来自动物实验,据此假定为一种小肠疾患,称为沙门氏菌肠炎。在许多病人临床表现为大量水样腹泻伴有腹部脐周绞痛,符合小肠性腹泻的特点。但另一些患者则有小量血性大便、里急后重、乙状结肠部位触痛等痢疾样特征。

Clinical manifestations in many patients with large amounts of watery diarrhea associated with abdominal umbilical colic, in line with the characteristics of intestinal diarrhea. However, other patients have a small amount of bloody stool, tenesmus, sigmoid colon tenderness and other diarrhea-like features.
