Currently, I am seeing MDR TB patients in Swaziland and have come across the issue of Mycobacterium other than tuberculosis (MOTT) in some of our culture results. I am curious as to what clinicians have been doing with this information. If it is only one culture with this issue, we generally ignore it. But what to do if the patient has 2 or more cultures gorwing out MOTT. And how would you manage this in HIV co-infected cases? We are not able to speciate the MOTT as this time. Any kind of experience dealing with MOTT would be greatly appreciated.
