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 ...200919846643
respiratory infections associated with nontuberculous mycobacteria in non-hiv patients.the incidence of nontuberculous mycobacteria (ntm) pulmonary diseases in hiv-negative patients was studied prospectively from january 1, 2001 to december 31, 2003 by 32 sentinel sites distributed throughout france. in total, 262 patients who yielded ntm isolates from respiratory clinical specimens, met the bacteriological, radiological and clinical criteria established by the american thoracic society for ntm respiratory disease. among the 262 ntm isolates, 234 were slow-growing mycobacteria (12 ...200617138678
mycobacterium avium complex common-source or cross-infection in aids patients attending the same day-care 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.19989801289
