Staphylococcus pasteuri bacteraemia in a patient with leukaemia

摘要

Coagulase-negative staphylococci are frequently isolated from clinical specimens and they represent the most common cause of bacteraemia in hospitalised patients. Particularly, venous catheter-related bloodstream infections are often due to non-aureus staphylococci. These are opportunistic pathogens in immunocompromised hosts and may behave as reservoirs of antibiotic resistance determinants.rnA 75-year-old woman was admitted to hospital because of diffuse bone pain. A relapse of myeloid acute leukaemia was diagnosed (the first diagnosis had been made 5 months earlier), and she was admitted to the haematology department. Nine days later she developed fever (to 39℃) and chills. A Gram-negative infection was suspected, and blood samples (the set included two BacT/Alert aerobe/yeast bottles (bioMerieux, Marcy l'Etoile, France) plus one anaerobe bottle) were taken for culture.
