Usually, fecal macrophages are found in the feces of patients suffering from bacillary dysentery, enteritis, and rectal cancer, and their morphology is characterized by their large size, which can be dispersed or distributed in clusters. When bacteria or viruses invade the human intestines and release toxins or cause damage to the intestinal mucosa, macrophages will phagocytose the bacteria, viruses, and necrotic tissues, dissolve them, and then excrete the residues outside the cells. The morphology of phagocytes in feces is characterized by the large volume of phagocytes, which is 3 times or more than the volume of small phagocytes, irregular shape, often with protrusions at the edge, small nucleus, not lobed, and the cells contain phagocytosed particles, but also phagocytosis of erythrocytes, bacteria, viruses and so on, which can be scattered in distribution or distributed in groups. For the results of fecal examination, you should find a regular hospital doctor to analyze and judge, do not blindly seek methods, so as not to delay the treatment process.
