Bacillus cereus is a Gram-positive spore-forming rod widely found in the environment and is thought to be a frequent source of contamination. This micro-organism is reportedly a significant pathogenic agent among immunocompromised individuals. Furthermore, multiple cases of fulminant septicaemia
A 64-year-old man with acute myelogenous leukemia (FAB classification, M7) in remission received consolidation chemotherapy with mitoxantrone/cytosine arabinoside. WBC counts decreased to 0/microl on day 14, and fever (39.3 degrees C) and epigastralgia developed on day 15. Cefozopran was instituted
A 5-year-old boy with standard-risk B-cell acute lymphoblastic anemia developed fever during induction chemotherapy. The patient had no neurological symptoms. Blood cultures grew Bacillus cereus and neuroimaging studies demonstrated a cerebral abscess. Imaging changes resolved after completion of
Background. Five neuroinvasive Bacillus cereus infections (4 fatal) occurred in hospitalized patients with acute myelogenous leukemia (AML) during a 9-month period, prompting an investigation by infection control and public health officials. Methods. Medical records of case-patients were reviewed
Bacillus cereus is a gram-positive bacillus that is ubiquitously present in the environment, often regarded as a contaminant when isolated in clinical testing. Cases of B. cereus causing lower respiratory tract infections are sparse, with less than 20 reported in the literature, and
Bacillus cereus typically causes a self-limited foodborne gastrointestinal (GI) illness. Severe invasive infection occurs rarely, mainly among immunocompromised hosts. We describe a cluster of B. cereus infections among 5 patients with acute myeloid leukemia and chemotherapy-induced neutropenia. The
We report a pediatric case of critical illness polyneuropathy and myopathy caused by Bacillus cereus sepsis during acute lymphoblastic leukemia therapy. A 15-year-old boy developed B. cereus sepsis and multiple organ failure on the 19th day after initiation of chemotherapy, and multidisciplinary
Bacillus cereus, a ubiquitous, endospore-forming, aerobic gram-positive bacillus, is primarily associated with toxin-mediated food poisoning. Frequently, isolates of Bacillus species from clinical specimens are discussed as contaminants. We report a rapidly fatal case of disseminated infection due
Three patients with acute leukaemia, who were severely neutropenic and iatrogenically immunosuppressed post-chemotherapy, developed rapidly fatal septicaemic shock and coma caused by Bacillus cereus (B. cereus). The illness was marked by two phases: a mild febrile illness lasting 6-14 h and
Antibiotic dependence in clinical isolates has been reported, albeit rarely, such as vancomycin-dependent enterococcus and beta-lactam-dependent Staphylococcus saprophyticus. We report herein a clinical isolate of beta-lactam-dependent Bacillus cereus. A 16-yr-old female was admitted on 8 September
Bacillus cereus, which used to be considered non-pathogenic, was isolated from the blood of a patient with acute leukemia who was receiving intensive chemotherapy. Fatal bacteremia developed with a clinical syndrome of acute gastroenteritis, followed by both meningoencephalitis with subarachnoid
BACKGROUND
We herein report a fatal case of fulminant septicemia caused by Bacillus cereus in a 49-year-old female with T-cell acute lymphoblastic leukemia receiving chemotherapy.
METHODS
Her two blood culture sets were positive for Gram-positive, rod-shaped bacterium. Bacillus cereus was identified
Bacillus cereus is an aerobic Gram-positive, spore-forming, rod-shaped bacterium that is responsible for foodborne illnesses. We report on a 15-year-old girl with B-cell acute lymphoblastic leukemia, who fell into a somnolent state after presenting with a 12-hour history of fever, muscle soreness,
Central nervous system infection caused by Bacillus cereus is a rare condition, which often progresses rapidly and is fatal in immunocompromised patients. A 54-year-old woman with acute myelogenous leukemia fell into a coma with high fever during severe neutropenia while undergoing chemotherapy. A
