Finer snapshot of circulating Mycobacterium tuberculosis genotypes in Guadeloupe, Martinique, and French Guiana.

ABSTRACT

This study shows the benefit of spoligotyping coupled to mycobacterial interspersed repetitive-unit (MIRU) typing to pinpoint circulating Mycobacterium tuberculosis genotypes in Guadeloupe, Martinique, and French Guiana. We hereby propose reduced 4-locus and 6-locus subsets for LAM and Haarlem lineage strains that predominate in South America and the Caribbean, retaining 99.35% and 99.64% of the total discriminatory power of the 12-locus scheme, respectively.
