In 1980, a 32 years-old Madagascan female developed a pulmonary tuberculosis, bacteriologically confirmed. She cured with right apical cavitary sequellae. In 1989, she presented haemoptysis again. Antituberculous treatment was adopted without bacteriological confirmation and did not improve clinical symptoms. In 1991 and 1992 cultures from sputa and bronchi aspiration yielded acid-fast bacilli identified as Mycobacterium shimoïdei. M. tuberculosis could not be detected. The patient died during treatment. This case is the fourth one in the literature. Whereas previous cases have been reported in Europe, Australia, Asia, this new case shows M. shimoïdei is also present in Africa.
