Fig. 2From: Comparative genomic characterization of multidrug-resistant Citrobacter spp. strains in Fennec fox imported to ChinaA core-genome analysis of 277 Citrobacter strains, including four isolates from this study and 273 strains downloaded from NCBI genome database. The year of the isolation is labelled in the outer ring. The source of the strains is presented in the middle ring. The location of the isolates is colored in the inner ring. Isolates identified in this study were colored in red. NA, details regarding the region of the strains is not available. The bar shows 100,000 nucleotide substitution per positionBack to article page
