A 26 year-old woman with fever and dyspnea due to disseminated Mycobacterium kansasii infection is reported. Mycobacterium kansasii was isolated in sputum, gastric juice and bone marrow cultures. Unlike the fatal termination in other reported cases of this type of disease, our patient responded completely to rifampicin, ethambutol, cycloserinum and ethionamidum therapy. The bacilli showed in vitro sensitivy to these four antibiotics.
Infection with Mycobacterium kansasii is rarely reported compared to other acid-fast organisms in Japan, and this case is the first case of Disseminated Mycobacterium kansasii Infection in our country.
