title: Rifampicin resistance in tuberculosis outbreak, London, England.
abstract: Mycobacterium tuberculosis isolates cultured from 6 patients associated with an isoniazid-resistant M. tuberculosis outbreak acquired rifampicin resistance. The rpoB gene sequence showed that resistance was associated with rare mutations in each isolate. Three isolates had a mutation outside the rifampicin resistance-determining region.
