Abstract:
We used restriction-fragment-length-polymorphism (RFLP) DNA fingerprinting to document exogenous reinfection with a multidrug-resistant strain of Mycobacterium tuberculosis in an immunocompetent patient. Molecular epidemiologic studies using RFLP analysis may elucidate the epidemiology of exogenous reinfection with M. tuberculosis.
