MOLECULAR EPIDEMIOLOGY OF TREPONEMA PALLIDUM IN BORDER REGION OF RUSSIAN FEDERATION (TUVA REPUBLIC).

[Article in English, Russian]

Abstract

The 111 strains of T. pallidum subsp. pallidum collected in Tuva Republic in 2013-2016 were typed by the arp, tpr (E, G, J) and tp0548 genes. The 7 subtypes were identified, in which the 14 d/f type was predominant (90.1%). The minor subtypes 14 b/f, 14 c/f, 14 d/g and 14 i/f constituted 0.9-1.8%. Single strains of 4 d/f H 9 d/f types (each 0.9%) previously described in China were detected in 2015. Both 9 and 14 arp gene variants were found in 3 clinical specimens for the first time in 2015-2016. Similarities in the molecular epidemiology of syphilis in Tuva Republic and Russia were demonstrated as well as differences from the T. pallidum subsp. pallidum population in China and Western Europe.
