Fig. 4From: The evolution and population structure of Lactobacillus fermentum from different naturally fermented products as determined by multilocus sequence typing (MLST)Minimum spanning tree analysis of 203 L. fermentum isolates based on allelic profiles of 11 gene fragments and according to food-type origin. Each circle represents the sequence type, the size of the circle is proportional to the number of isolates within any given ST. The strength of links are: black line = strong relationship; grey line = intermediate relationship; dotted line = weak relationship. STs belonging to the same clonal complex, are indicated by the surrounding shading. Gray line was drawn as boundaries of each groupBack to article page
