BACKGROUND AND OBJECTIVES Avian tuberculosis is one of the most important infections affecting most species of birds. Mycobacterium avium can not only infect all species of birds, but also infect some domesticated mammals. The most crucial aspect of control and eradication scheme is identification of infection sources and transmission routs. Molecular techniques such as restriction fragment len...
This study investigated the changes in the major etiologic organisms and clinical phenotypes of nontuberculous mycobacterial lung disease (NTM-LD) over a recent 15-year period in Korea. The increase of number of patients with NTM-LD was primarily due to an increase of Mycobacterium avium complex (MAC) lung disease (LD). Among MAC cases, the proportion of M. avium increased compared with M. intr...
Recovery of Mycobacterium avium complex organisms from 412 lysis-centrifugation (Isolator) concentrates of blood specimens obtained from human immunodeficiency virus-positive individuals was attempted with the following media (and Isolator concentrate inoculum volumes): BACTEC 12B broth (0.2 and 1.0 ml), Lowenstein-Jensen slants (0.1 ml), and Middlebrook 7H10/11 agar (0.1 ml). A total of 42 M. ...
We prospectively studied 298 patients with cystic fibrosis (mean age 11.3 years; range 2 months to 32 years; sex ratio, 0.47) for nontuberculous mycobacteria in respiratory samples from January 1, 1996, to December 31, 1999. Mycobacterium abscessus was by far the most prevalent nontuberculous mycobacterium: 15 patients (6 male, 9 female; mean age 11.9 years; range 2.5-22 years) had at least one...
To evaluate the prognostic implications of computed tomography (CT) findings in assessing responses to treatment in Mycobacterium avium complex (MAC) pulmonary disease without underlying lung disease, high-resolution (HR)CT findings were correlated based on the results of sputum conversion after anti-MAC therapy. A total of 59 patients underwent HRCT before treatment and the therapeutic efficac...
One of the most important opportunistic pathogens associated with AIDS is the Mycobacterium avium complex. M. avium infections are found in up to 70% of individuals in advanced stages of AIDS. The deficiency in our knowledge of these mycobacteria presents an obstacle to the development of a rational approach for controlling these life-threatening infections in immunocompromised persons. It is a...
Comparison of antituberculosis drug regimens for lung disease caused by Mycobacterium avium complex.
A total of 123 patients with moderately advanced, cavitary lung disease caused by Mycobacterium avium complex untreated previously received different regimens of antituberculosis agents. The rate of sputum conversion (continuously negative cultures for six months or more) was compared among the regimens. It was shown that the regimens of rifampin + isoniazid + streptomycin and rifampin + isonia...
