Resources for healthcare professionals about the national TB strain typing service.
The national strain typing service involves prospectively typing TB isolates using 24 loci mycobacterial interspersed repeat units - variable number tandem repeats (MIRU-VNTR). The results of this are used in local or national investigation of suspected TB transmission incidents.
TB strain typing results combined with epidemiological data can:
- help identify TB patients potentially involved in the same chain of recent TB transmission
- assist in initiating timely and appropriate control measures following cluster and outbreak investigations
- provide an opportunity to better understand the epidemiology of TB in a given setting
