>From a sputum sample described as "Normal Upper Respiratory tract flora".
AFB was not seen.
The sample was cultured for TB
Declared negative after 4 weeks.
One month later the same sample was noted to have a microbacterium s.p.
After being sent for identification and culture sensitivity it was reported
some 5 weeks later as:
"M. Chelonae Common Environmental saprophyte
END REPORT."
The patient is HIV negative
I would like to ask the following
1. From this sample can it be said that there is evidence of
microbacterium infection?
2. Was M. Chelonae cultured or was it already present in the sample?
3. Has a TB organism been cultured?
4. Is M. Chelonae in this setting a cause of TB?
A very genuine enquiry
