Abstract

To the Editor:

I read the recent publication by Lin et al¹ on urinary Mycobacterium szulgai infection with a great interest. Indeed, this nontuberculosis (non-TB) Mycobacterium infection, similar to other non-TB agents, is well described for induction of lung infection. Thomson and Yew² noted that attention to pulmonary hygiene and underlying diseases without immediate antimycobacterial therapy may be more appropriate in some cases. Thomson and Yew² also noted that a considerable proportion of apparently immunocompetent patients with this infection appeared to be rising.² Focusing on the urinary atypical Mycobacterium infection, there are continuous case reports. For example, the first case report of urinary Mycobacteria gordonae infection was reported in January 2009. It seems that there will be increased reports on urinary atypical Mycobacterium infections.³ This might be due to more concern of the present physician on these neglected Mycobacterium infections.
