BACKGROUND
Endophthalmitis is a serious intraocular infection that frequently results in significant inflammation and vision loss. Because current therapeutics are often unsuccessful in mitigating damaging inflammation during endophthalmitis, more rational targets are needed. Toll-like receptors
A 64-year-old man in a severely immunocompromised state due to acute myelogenous leukemia died, respirator-unaided, about 10 h after the abrupt onset of coma. An earlier blood culture had yielded Bacillus cereus. The autopsy, performed 2 h after death, demonstrated diffuse subarachnoid hemorrhage
OBJECTIVE
To determine whether the usual clinical dose of intravitreal dexamethasone can attenuate intraocular inflammation and retinal necrosis in a rabbit model of fulminant Bacillus cereus endophthalmitis induced by crude exotoxins.
METHODS
Thirty-six eyes from pigmented mongrel rabbits received
Host recognition of microbial components is essential in mediating an effective immune response. Cytosolic bacteria must secure entry into the host cytoplasm to facilitate replication and, in doing so, liberate microbial ligands that activate cytosolic innate immune sensors and the inflammasome.
Eosinophils used to be thought of as regulators of allergic inflammation, but there is now evidence to the contrary; eosinophils have been found to be the major effector cells responsible for the late asthmatic response (LAR), airway hyperresponsiveness (AHR) and, at least in part, airway remodeling
Bacillus cereus can cause endophthalmitis through secretion of virulence factors, including hemolysin BL (Hbl) and nonhemolytic entertoxin (Nhe). Carvacrol is an extract from oregano oil, with potential for curtailing B. cereus endophthalmitis, due to antimicrobial and
OBJECTIVE
To evaluate the effects of intravitreal moxifloxacin with or without dexamethasone on experimental Bacillus cereus endophthalmitis.
METHODS
The right eyes of 21 New Zealand albino rabbits weighing 2-3 kg were used in this study. Each eye was inoculated with 1×10(6) colony-forming units of
BACKGROUND
Bacillus species remain an important cause of post-traumatic endophthalmitis, often causing permanent visual loss.
METHODS
Twenty two rabbits were used to evaluate the clinical and histological findings of Bacillus cereus experimental post-traumatic endophthalmitis. Eyes that had received
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
OBJECTIVE
The authors compare the intravitreal efficacy of ciprofloxacin, vancomycin and imipenem, in treating experimental Bacillus cereus endophthalmitis.
METHODS
Thirty-three Yorkshire pigs received a surgically induced injury to the right eye, which was then repaired and injected with 8400
OBJECTIVE
To determine the contribution of tumor necrosis factor-alpha (TNFalpha) in the pathogenesis of experimental Bacillus cereus endophthalmitis.
METHODS
Experimental B. cereus endophthalmitis was induced in wild-type control (B6.129F1) and age-matched homozygous TNFalpha knockout mice
Bacillus cereus was able to grow and produced local infections following subcutaneous or intramuscular injection. An inflammatory response was produced with necrosis of muscle fibres and calcification. The organism was sensitive to chemotherapeutic agents on in vitro tests.
Bacillus cereus is a rare cause of serious human infection but, paradoxically, causes one of the most severe posttraumatic or endogenous infections of the eye, endophthalmitis, which frequently results in blindness. The virulence of B. cereus endophthalmitis historically has been attributed to toxin
OBJECTIVE
To investigate whether intravitreal corticosteroid therapy reduces the extent of inflammatory intraocular tissue damage caused by Bacillus cereus endophthalmitis.
METHODS
New Zealand white rabbits were inoculated with 1 x 10(6) B cereus organisms and randomized to receive no treatment
