From: Characterization of Mycobacterium tuberculosis Beijing isolates from the Mediterranean area
Comparative analysis of IS 6110 -RFLP (A), MIRU-15 (B), and MIRU-15+5 (C) in the 26 clinical Beijing isolates. aOrder of QUB loci: QUB 11a, QUB 3232, and QUB 18. bOrder of VNTR loci: VNTR3820 and VNTR4120. The clustered cases are indicated within boxes. C1 and C2 refer to the cases included in the two clusters defined by RFLP. In some cases, the large size of some products obtained in QUB and the VNTR loci did not allow precise assignation of alleles. In these cases we could only estimate that the number of repetitions was higher than 20 (> 20). When we observed products differing in size in groups of isolates with more than 20 repetitions, we sub-labeled them > 20a, > 20b, > 20c and > 20d.
