During abdomen palpation are noticed spasms and soreness of the colon, mostly frank in sigmoid colon area which is palpated in the form of thick binder.

Bowel movement occurs more often, dejections initially have fecal character, then they have mixture of mucus and blood., then is effused a little amount of mucus with threads of blood. Duration of the disease is from 1 to 9 days.

Recognition
For the recognition is used data of epidemiological anamnesis. clinical manifestations such as common intoxication, frequent dejection with mucus or blood, cramp-like pains in abdomen in left side. Important role plays rectosigmoidoscopy which helps to detect signs of mucus inflammation in distal areas of rectum. Release of dysenteric microbes during bacteriological examination of excrement proves the diagnosis.

Treatment
Dysenteric patients may be treated in a contagious hospital and at home as well. It is necessary to take antibiotics such as tetracycline ((0,2-0,3g four times daily), laevomycetin (0,5g four times daily during 6 days).

However, microbes resistance to antibiotics was increased greatly and their effectiveness has reduced. Also are used furasolidone, nitrofurantoin 0.1g four times a day during 5 – 7 days. Vitamins are recommended. In severe cases is made detoxification therapy.
