Auntie - I think we discussed this before. It is spelled MYCOBACTERIA
not Microbacteria. This is important if you want to look up anything
about the organism.
A common environmental saprophyte is found in the environment - it means
that it probably is not causing an infection and may be a contaminant of
If your smears were positive for acid fast bacteria, a doctor is going
to begin treatment even before he knows which mycobacterium he is
treating. M. tuberculosis and M. chelonei can look the same on a
microscope slide, and the organisms can take weeks to grow. They're not
going to take the chance of you spreading TB around while they're
waiting for a culture to grow.
As far as treatment with negative cultures, what do your physicians say?
Without knowing the sequence of events, it's hard to comment on your
report or question.

>> I would like an answer to two questions:
>> 1. Microbacteria Chelonei in sputum was labelled by lab "Common
> Environmental Saphroyte" could some explain in layman's terms what that
>> 2. What is ok then for Drs to begin treatment for tuberculosis even though
> three further sputum's were negative?
>> Thanks in advance
