Clinical scoring was based on the evaluation (0 4) from the last two parameters: 0, formed stool and absence of blood trace; 1, diarrhea; 2, diarrhea and presence of blood trace in stool; 3, diarrhea and rectal bleeding; 4, diarrhea and rectal bleeding with rectal prolapse.
The cheapest and least invasive is the fecal occult blood test, which looks for traces of blood in stool.
The most commonly used screening test for colon cancer checks for traces of blood in stool samples.
Moreover, detection of traces of blood in stool was in particular among Shigella-infected children.
Thus, only with one accurate method traces of blood in stool might associate with bacillary dysentery (Table 2).
The main difference concerned fecal occult blood, while with all etiologic agents the presence of traces of blood in stool had been less frequent, and the number of Shigella infected children was higher than expected (P < 0.001).
Advanced polyps and cancers bleed intermittently and the faecal occult blood test (FOBT) is used to detect trace amounts of haemoglobin in stool samples.
The Shigella species carrying sen/ospD3 gene for ShET-2 enterotoxin hemolysin were more frequent in children that had traces of blood in stools (P = 0.042).
Disease activity scores for DSS treated mice were based on the cumulative scores (0 10) from 3 different parameters: Stool consistency (0 = normal, 1 = soft but still formed, 2 = very soft, 3 = diarrhea), presence of blood in stool (0 = negative heamocccult, 1 = positive hemoccult, 2 = blood traces visible in stool, 3 = rectal bleeding) and histological changes (0 4).
No significant differences were observed in stool form as determined by use of the Bristol stool scale.
