Widespread Environmental Contamination with Mycobacterium tuberculosis Complex Revealed by a Molecular Detection Protocol.

Environmental MTCcontamination was detected in all types of samples The proportion of MTC-positive samples in the bTB-infected area was higher (0.32, CI 95 0.20–0.49) than in the bTB presumed negative area (0.18, CI 95 0.08–0.34), although this difference did not reach statistical significance (p = 0.15, Pearson’s χ 2 ) ( Table 1 ).
