Since the advent of the acquired immunodeficiency syndrome (AIDS) numerous M. avium intracellulare disseminated infections have been recognised. Blood culture is a convenient method for diagnosing these infections. At Pitié-Salpêtrière hospital AIDS patients with persistent unexplained fever each had three blood cultures. The blood samples, taken on 3 consecutive days without taking in account fever peaks, were collected in the Isolator-10 lysis-centrifugation system and inoculated onto Lowenstein-Jensen medium with and without 0.25% sodium pyruvate. From February 1986-September 1987, 564 samples taken from 165 patients were cultivated for the detection of mycobacteria. Sixty one (10.8%) taken from 19 patients (11.5%) were positive. M. avium intracellulare was the most frequently isolated mycobacterial species. In 10 patients, the positive blood culture was the only or the first positive culture for mycobacteria.
