RECOMBINANT CHIMERIC POLYPEPTIDES, CARRYING EPITOPES OF VARIOUS IMMUNODOMINANT PROTEINS OF SPIROCHAETA OF BORRELIA BURGDORFERI SENSU LATO COMPLEX, AND SERUM DIAGNOSTIC TECHNIQUE FOR IXODIC TICK-BORNE BORRELIOSIS Russian patent published in 2014 - IPC C07K19/00 C07K14/235 G01N33/53 G01N33/68 

Abstract RU 2514230 C1

FIELD: medicine.

SUBSTANCE: there are presented recombinant chimeric polypeptides rmBmpA-frp83, rmOspA-frp83, rmDbpB-rmOspA, rmFlaA-frFlaB and rmOspCBg-rmOspCBa, prepared on the basis of gene expression amplified by PCR on the DNA of Borrelia garinii 20047T Western-Siberian isolate or in case of the protein rmOspCBa, on the DNA of Borrelia afzelii isolate.

EFFECT: invention extends the range of recombinant polypeptides applicable for the serum diagnosis of ixodic tick-borne borreliosis, providing higher specificity and sensitivity of the ITBB, including the differential diagnosis of the early stage and the stage of a disseminated infection in the territories of Borrelia burgdorferi s1 Western-Siberian isolates.
