title: [Macrolide resistance in Treponema pallidum subsp. pallidum in the Czech Republic and in other countries].
abstract: Treponema pallidum subsp. pallidum (TPA) is the causative agent of the sexually transmitted disease syphilis. In the Czech Republic, several hundred cases of syphilis are reported annually; e.g. in 2012, 696 syphilis cases were documented. In the last decades, an increasing prevalence of macrolide resistant TPA strains harboring A2058G or A2059G mutations in the 23S rRNA gene has been reported. Macrolides were used (and rarely are still being used) in the Czech Republic for the treatment of syphilis in patients allergic to penicillin. While 37% of TPA strains were resistant to macrolides between 2004 and 2010, this rate increased to 67% between 2011-2013. High prevalence of A2058G or A2059G mutations and increasing rates of macrolide resistant TPA strains have also been documented in other developed countries. Therefore, macrolides should not be used in the treatment of syphilis.
