Figure
Figure. Phylogenetic tree of 19Neisseria gonorrhoeae isolates, including 2 from patients in France, compared on the basis of their main resistance determinants. The phylogenetic tree was built from 10,907 total core single-nucleotide polymorphism positions. The F95 and F96 isolates from 2 patients in France were compared with ceftriaxone-resistant and extensively drug-resistantN. gonorrhoeae isolates from Europe, Australia, Cambodia, Japan, and the United States. The tree is rooted onN. gonorrheae FA1090, a laboratory reference strain. Scale bar indicates the branch length corresponding to genetic change.
