High-level ceftriaxone resistance due to transfer of penA allele 60.001 into endemic gonococcal lineages in Hangzhou, China.

Here, we report continued transmission of gonococcal strains associated with the FC428 clone or containing penA allele 60.001 in Hangzhou. A major concern for public health is the acquisition of penA allele 60.001 by successful endemic lineages, which might enhance the transmission of this high-level ceftriaxone resistance trait.
