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
the culture.

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.
