Successful treatment of Chromobacterium violaceum sepsis in South Africa.

Chromobacterium violaceum sepsis is extremely rare and usually fatal. A very few cases of C. violaceum infection have been reported from Africa, but never from South Africa. As far as could be ascertained, this infection has never been reported in a patient with leukaemia. We describe what we believe to be the first such case of C. violaceum sepsis, in a 16-year-old female patient with acute biphenotypic leukaemia, which developed during the neutropenic phase after intensive chemotherapy. The infection was due to a non-pigmented strain of C. violaceum and was associated with a co-infection with Candida parapsilosis; both were successfully treated using broad-spectrum antibiotics, antifungals and removal of a Hickman line.
