[Role of dysbacteriosis in the development of surgical infection]. 
The intestinal microflora was examined in 230 patients operated on for abdominal abnormalities and injuries.  There were profound intestinal microbiocenotic impairments as appeared as lower bifidobacteria, intensive growth of opportunistic (coccal) microorganisms.  A direct relationship was established between the severity of dysbacteriosis and the incidence of pyoinflammatory complications in the postoperative period.  The use of live bacterial preparations in the complex therapy of patients with expected and emergency abdominal diseases or injuries reduced the number of pyoinflammatory complications and improved the therapeutic outcomes of patients with peritonitis.
