RT Journal Article T1 Spoligotyping Profile Change Caused by Deletion of a Direct Variable Repeat in a Mycobacterium tuberculosis Isogenic Laboratory Strain A1 Aranaz Martín, Alicia A1 Romero Martínez, Beatriz A1 Montero Serra, Natalia A1 Álvarez Sánchez, Julio A1 Bezos Garrido, Javier A1 Juan Ferré, Lucía De A1 Mateos García, Ana Isabel A1 Domínguez Rodríguez, Lucas José AB Spoligotyping is a major tool for molecular typing of Mycobacterium tuberculosis complex organisms. For epidemiological purposes, strains are considered clonal only when their spoligotyping patterns are identical. We report a change in the spoligotyping profiles of truly isogenic strains (a clinical isolate and a subculture derived in the laboratory) caused by deletion of a direct variable repeat. Without the information about the relationship between them, a link between these strains would have gone unnoticed. Evolutionary events should be taken into account in the interpretation of spoligotyping results and in the design of databases.
