Risk of acquisition was greatest for nurses and medical receptionists. Active tuberculosis later developed in one healthcare worker and one hospitalized patient. Nosocomial transmission was supported by epidemiological evidence and DNA fingerprinting. The outbreak strain of\n Mycobacterium tuberculosis<\/jats:italic>\n differed from other isolates at this hospital, but its DNA hybridization pattern was highly similar to that of the multidrug-resistant outbreak strain W that has been prevalent in New York City, suggesting a common strain ancestry. However, the Tennessee isolates were susceptible to all first-line antituberculous agents.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n This report suggests the possibility that a molecular characteristic(s) shared by these successful outbreak strains is associated with increased transmissibility or pathogenicity and emphasizes the need for continued vigilance for tuberculosis
