This study aimed to reassess rates of syphilis azithromycin resistance in Dublin. Of the 104 samples, 36 (34.6%) were positive for Treponema pallidum DNA by polymerase chain reaction. Thirty samples were analyzed for A2058G mutation, 29 samples sequenced. Of the 29 samples, 27 (93.1%) had the mutation. Azithromycin cannot be recommended for the treatment of syphilis in Dublin.
Dublin continues to have a very high proportion of azithromycin resistant syphilis isolates. Azithromycin cannot be recommended for syphilis treatment in those who have acquired their syphilis in Ireland.

The rate of azithromycin resistance in Dublin remains high. Azithromycin cannot be recommended for syphilis treatment in Dublin, or for the epidemiological treatment of syphilis.
