Prevalence of Mycobacterium lentiflavum in cystic fibrosis patients, France

Abstract : Background: Mycobacterium lentiflavum is rarely isolated in respiratory tract samples from cystic fibrosis patients. We herein describe an unusually high prevalence of M. lentiflavum in such patients. Methods: M. lentiflavum, isolated from the respiratory tract of cystic fibrosis patients, was identified using both rpoB partial sequencing and detected directly in the sputum by using real-time PCR targeting the smpB gene. Results: M. lentiflavum emerged as the third most prevalent nontuberculous mycobacterial species isolated in cystic fibrosis patients in Marseille, France. Six such patients were all male, and two of them may have fulfilled the American Thoracic Society clinical and microbiological criteria for M. lentiflavum potential lung infection. Conclusions: M. lentiflavum was the third most common mycobacteria isolated in cystic fibrosis patients, particularly in six male patients. M. lentiflavum outbreaks are emerging particularly in cystic fibrosis patients.
