Fig. 1From: Multilocus sequence typing of Streptococcus thermophilus from naturally fermented dairy foods in China and MongoliaMinimum-spanning tree analysis of 239 Streptococcus thermophilus isolates and 18 reference strains based on the allelic profiles of 10 genes. Each circle corresponds to a sequence type (ST), and the circle size denotes the number of strains sharing the same ST. Colored zones between some groups of circles indicate that these profiles belong to the same clonal complex (CC). The strength of the link (bold, plain, or discontinuous) is related to the genetic similarity (number of common alleles) between profiles. Black line was drawn as boundaries of each branchBack to article page
