Patterns of multiple
. infections as obtained by RFLP and spoligotyping techniques. The first three isolates have only one band by RFLP (non-Beijing) and spoligotype T1; the 4th sample is a mixture of Beijing genotype (as obtained by RFLP) and spoligotype T1. The 5th sample has no RFLP banding pattern and an undefined spoligotype, whereas for the last three isolates no banding patterns were found by RFLP and spoligotyping, probably as a result of the presence of non-tuberculous mycobacteria (NTM).
