When the intestine is infected by this bacterium, it will not only affect the absorption and peristaltic function of the intestine causing diarrhea, but the intestine will also secrete some pus and exudate due to the stimulation caused by the bacterium, which are green in color, and when the secretion is too much the feces will appear green. When there are too many secretions, the feces will appear green. During an attack of acute enteritis, the stool is acidic in nature because it is retained in the intestine for a longer period of time, and part of the bilirubin is converted into bilirubin by the action of intestinal bacteria, so the stool will be light green in color. Most people with a cold spleen and stomach will have loose stools, and once these people consume too much green vegetables, it will affect the color of their stools, so they will have green loose stools during defecation.
