The properties of Escherichia isolated from the bodies of mice in bacterial translocation after immobilization stress

As revealed in experiments on mice, 6-hour immobilization stress initiates the process of the translocation of intestinal flora to mesenteric lymph nodes and the blood. This process is accompanied by the infection of parenchymatous organs (the liver, the spleen, the kidneys, the lungs) and the increase of the concentration of E. coli in the proximal sections of the digestive tract (the duodenum and the jejunum). As the result of the comparative analysis of the phenotypic signs of bacterial isolates obtained from intestinal and "extraintestinal" E. coli populations, the accumulation of clones with highly pronounced seroresistance and such persistence characteristics as anticomplementary and antilysozume signs, as well as resistance to the bactericidal action of leukocytic cation protein with a molecular weight of 11.0-11.5 kD, has been found to occur in the body (the blood, parenchymatous organs and the small intestine).
