Fig. 3: Phylogeny of the global S. sonnei isolates with a heatmap showing the distribution of AMR determinants.
From: A Shigella sonnei clone with extensive drug resistance associated with waterborne outbreaks in China
The region covered by color patches on the evolutionary tree represents the outbreak strains in different regions, and the two bands at the left of the heatmap indicate the information of the country and province of the strains, respectively. Blue stripes represent the identity of different types of AMR genes, showing genes with only more than 90% coverage and 70% identity. GyrA mutations, including S83L, D87Y, and D87G, are separately indicated by the colors red, gamboge, and yellow. Source data are provided as a Source Data file. cefRaziR coresistance to ceftriaxone and azithromycin, AMR antimicrobial resistance.
