Fig. 2. Evolutionary relationships of por gene of TRNG and non-TRNG isolated in Korea during 2006 (A) and 2010–2011 (B). The phylogenetic tree was drawn by MEGA6 software using the Neighbor-Joining method. Allele numbers belonging to TRNG are marked with a red dot. TRNG, high-level tetracycline-resistnat Neisseria gonorhoeae; MEGA6, Molecular Evolutionary Genetics Analysis version 6.
