PCR Procedures used for species and lineage identification of M. tuberculosis complex isolates obtained in this study.

PCR polymerase chain reaction; RD = regions of difference;+ = locus intact; − = locus deletedOTCF = Other than Cameroon family; CF = Cameroon familyWAfri = West-African type. nd = not determined.聚合酶链式反应（Polymerase Chain Reaction，PCR）；差异区域（Regions of Difference，RD）：“+”代表基因座完整（Locus Intact），“−”代表基因座缺失（Locus Deleted）；OTCF（非喀麦隆家系，Other than Cameroon Family）；CF（喀麦隆家系，Cameroon Family）；WAfri（西非型，West-African Type）。nd（未确定，Not Determined）。
