[Cell-cooperation integrated test for the detection of immune reactivity to Shiga-toxin in patients with acute intestine infection].

Described are the results of approbation of the cell-migration screening test reflecting the outcome of cooperation between T- and B-cells and macrophages. It was shown, in adults and children with intestine infection, to be a highly-effective tool for the detection of suppressed immune response during early disease stages at stimulation in vitro by Shiga toxin at nano- and picogram concentration; it can also be used for the evaluation of the shaping specific anti-Shiga-toxic immune response. The parameters of the migration activity of peripheral-blood leucocytes at exacerbation and convalescence were demonstrated to correlate with the age of sick children and with the severity of intestine infection as well as with the level of a Shiga-like toxin detected in coprofilters and circulating immune complexes.
