| multicenter study of prevalence of nontuberculous mycobacteria in patients with cystic fibrosis in france. | we performed a multicenter prevalence study of nontuberculous mycobacteria (ntm) involving 1,582 patients (mean age, 18.9 years; male/female ratio, 1.06) with cystic fibrosis in france. the overall ntm prevalence (percentage of patients with at least one positive culture) was 6.6% (104/1,582 patients), with prevalences ranging from 3.7% (in the east of france) to 9.6% (in the greater paris area). mycobacterium abscessus complex (mabsc; 50 patients) and mycobacterium avium complex (mac; 23 patien ... | 2009 | 19846643 |
| mycobacterium avium complex common-source or cross-infection in aids patients attending the same day-care facility. | to delineate the epidemiology of mycobacterium avium complex (mac) infection in acquired immunodeficiency syndrome patients, we studied 32 case patients with disseminated mac infection who attended the same daycare facility during a period of 13 months. pulsed-field gel electrophoresis analysis showed very low similarity between mac strains, suggesting that, despite close contacts between the patients, nosocomial cross-transmission or exposure to a common source of mac did not occur. | 1998 | 9801289 |
