Acute watery diarrhea is most commonly seen with traveler's diarrhea caused by enterotoxigenic E. coli (ETEC), parasite-induced diarrhea from Giardia and Cryptosporidium spp. and, in cases of food poisoning (ingestion of preformed toxins), from B. cereus and S. aureus.
Watery diarrhea is the main symptom regardless of the severity of the infection, although it may not be present in every patient. Some patients are carriers of the organism and do not develop an active infection. These individuals may shed the organism and cause environmental contamination. Generally, mild C. diff infection (in addition to diarrhea) may result in: 1  abdominal pain and cramping, 2  bloating, 3  nausea, 4  vomiting, 5  fatigue, and. 6  fever.
