Massive intravascular hemolysis: a fatal complication of clostridium perfringens septicemia in a patient with acute myeloid leukemia.

We describe a fatal case of a 74-year old man with acute myeloid leukemia complicated by massive intravascular hemolysis due to Clostridium perfringens sepsis.

Micrococcus luteus: a putative cause of hepatic abscess?

Micrococcus luteus was repeatedly isolated in blood cultures during a prolonged feverish syndrome in a patient who presented with multiple hepatic abscesses as well. In contrast to the literature, this case is not related to prosthetic devices; an untreated limb wound may have been the site of microbial entry.

Moraxella catarrhalis endocarditis: case report and review of the literature.

A case of bacterial endocarditis caused by Moraxella catarrhalis in an apparently immunocompetent Greek male is presented, which was diagnosed after a 2-month history of low-grade fever of unknown origin. The agent seems to be a rare pathogen, but due to the high mortality rate, it should always be considered in the differential diagnosis of relevant cases. Beta-lactamase production by many strains complicates the choice of antibiotic.

Bacteroides fragilis arthritis in a sickle cell-thalassaemia patient.

Anaerobic arthritis due to Bacteroides fragilis was diagnosed in a 33-year-old patient with prolonged fever suffering from sickle cell/thalassaemia. The causative agent was isolated from blood and purulent synovial fluid from both knee joints. A combination of chloramphenicol plus metronidazole treatment proved effective.
