摘要: Mycobacterium chelonae was isolated from the blood of four immunosuppressed patients over a period 10 weeks. Three had intravascular catheters in situ and other biliary stent. All presented with recurrent fever despite treatment broad-spectrum antibiotics. Blood cultures using standard bacteriological medium yielded gram-positive bacillus each patient. Ziehl-Neelsen staining these demonstrated branching acid-fast that subsequently identified as case. The isolates were sensitive to clarithromycin and, although success monotherapy has been variable, this antibiotic combined removal used treat those three patients. successful no recurrence symptoms after 12 months follow-up. patient stent died soon isolated. Pyrolysis mass spectrometry analysis indicated two distinct strains. Radiological insertion Hickman lines implicated epidemiologically source infection.
