Carriage and colonization of C. difficile in preterm neonates: A longitudinal prospective study
Fig 2
Minimum-spanning tree representation of Multi-Locus Variable-number tandem-repeat Analysis (MLVA) data of the 199 C. difficile isolates.
The circles represent unique MLVA types and are scaled to member count. The numbers between the circles represent the STRDs (summed tandem repeat differences) between MLVA-types. Grey areas represent genetically related MLVA types (STRD ≤10). MLVA-types linked by a plain line are part of the same clonal complex (STRD ≤2). PCR-ribotypes are color-coded; * toxigenic strains.
