Summary:

DNA fingerprint techniques have been developed to type Mycobacterium tuberculosis isolates for studying the molecular epidemiology of tuberculosis. The previous concerted action projects have promoted optimal communication between EU partners, thus enabling standardisation of these methods, and meaningful interpretation and comparison of results from epidemiological studies in different areas. In this project, the plan is to maintain the established network in Europe and to use the DNA fingerprint database to trace transmission of (resistant) strains internationally, and to study the natural history and control of tuberculosis. Furthermore, the consortium aims to test the potential of novel genetic markers, derived from the recently established genome sequence of M. tuberculosis, and to explore the DNA chip and microarray technology to allow the use of multiple genetic markers with different molecular clocks.

Problem:

The treatment of a multidrug resistant tuberculosis case is not only very costly, but also an enormous burden for the concerned patient because of the long term treatment (often many years), the required compliance, the severe side effects caused by the use of multiple drugs, and the containment required at the infectious stage of the disease.  Furthermore, treatment is not always successful. Prevention is therefore of vital importance and the surveillance of transmission of (resistant) strains is crucial.
