TABLE 1.

Characteristics of bacterial isolates^a

^aSample number, name, origin, and reference(s) for isolates subjected to GeneChip analysis. The final five columns list isolates' genetic characterization according to spoligotype (where black or white squares indicate the presence or absence, respectively, of 43 specific spacer sequences in the direct repeat region), allele combination at katG codon 463 and gyrA codon 95 (principal genetic group 1 has katG463 CTG and gyrA95 ACC; principal genetic group 2 has katG463 CGG and gyrA95 ACC), base pair composition of pks15/1 (which either has deletions of 6 bp or 7 bp or remained intact), and presence (+) or absence (−) of TbD1.

^bSN68 represents an M. africanum-like isolate presenting an M. bovis-like phenotype (22).
