# Overlap between *B. cereus* group typing methods

Below is a schematic overview (using Venn diagrams) of the strain overlap between the 3 typing methods for the

*B. cereus* group: MultiLocus Sequence Typing (MLST), Amplified Fragment Length Polymorphism (AFLP), and MultiLocus Enzyme Electrophoresis (MLEE). As of August 1, 2019, the total number of isolates that have been typed by any one method is 5886. In addition, overviews of the overlaps among the 5 MLST schemes and among the 3 AFLP studies are shown. In each figure, the number of strains shared for all combinations of methods, schemes, or studies is given in the yellow boxes.

MLST schemes are abbreviated as follows:

**TH, Tourasse-Helgason; H, Helgason; K, Ko; P, Priest; CS, Candelon-Sorokin**.

AFLP studies are abbreviated as follows:

**AFLP1, Ticknor; AFLP2, Hill; AFLP3, Guinebretiere**.

After removal of the 0 isolates that exhibit conflicting data, the detailed breakdown of strain overlap for the remaining 5886 isolates and for all combinations of methods is given in the table below. Click on the number of isolates to get the list and information about the isolates shared by a given method combination. Methods are given in alphabetical order.
