Invasive Candida norvegensis infection in immunocompromised patients.

Invasive infection with Candida norvegensis has previously been reported only once. Three new cases of invasive infection with C. norvegensis are described. One patient with acute myeloid leukaemia and neutropenic septicaemia had positive blood cultures with C. norvegensis, and 2 patients with AIDS and prolonged unexplained febrile cachexia had positive cultures of C. norvegensis from multiple sites, including pericardium, liver, kidneys lymph nodes and bone marrow, on autopsy. In severely immunocompromised patients, C. norvegensis appears to be an emerging new pathogen.
