Abstrakt: Vacuolizing toxin (VacA) Helicobacter pylori is an important factor of pathogenicity of Helicobacter pylori and a basic marker in the diagnosis of helicobacteriosis and related diseases. A coagulation-based diagnostic test-system was elaborated for the detection of VacA in clinical samples. A fragment of vacA was cloned, for the purpose, in Escherichia coli and expressed in preparative quantities; the coded protein was purified and used in raising the diagnostic serum. The thus designed coagulating test-system was successfully tested under the modeling conditions with clinical samples. Therefore, the designed express method can be used for the invasion-free determination of VacA in patients with gastric and duodenal pathologies.
