Abstract
A persistent 8-year infection by a Beijing Mycobacterium tuberculosis strain from a previous outbreak after importation from West Africa obliged us to investigate secondary cases. We developed a multiplex PCR method based on whole-genome sequencing to target strain-specific single nucleotide polymorphisms (SNPs). In 1 week, we analyzed 868 isolates stored over 6 years. Only 2 cases (immigrants from Guinea Conakry) harbored the strain, which ruled out transmission-despite opportunities-and challenged some of the advantages associated with Beijing strains.Entities:
