2. Blood in the stools
Bloody diarrhea is usually called dysentery, and it is important to differentiate whether it is caused by E. coli, Shigellosis, or amebae. When bloody diarrhea is caused by E. coli, the type of strains usually associated with this problem is either enteroinvasive or enterohemorrhagic E. coli. They cause a severe inflammatory response in the gastrointestinal tract, and the lab would also report a high leukocyte count in the stools. These patients typically display fever as well, and they are often dehydrated.
