Abstract:
We present the case of a 57-year-old male with poor prognosis (trisomy 21 and monosomy 7) acute myeloid leukaemia (AML) who presented with rigors and fever during cytogenetic remission. Peripheral and central line blood cultures were positive for Mycobacterium chelonae and he commenced empiric treatment with meropenem, amikacin, clarithromycin and ciprofloxacin. It appears that M chelonae infection was responsible for persistent myelosuppression after expected recovery from chemotherapy, which subsequently precluded optimum treatment for AML.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
