Abstract
Endemic (nonvenereal) syphilis is relatively common in nonindustrialized regions of the world. We describe a case of local transmission in Canada and review tools available for confirming a diagnosis. Improved molecular tools and global clinical awareness are needed to recognize cases of endemic syphilis imported to areas where it is not normally seen.

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.
