OBJECTIVE
We report the first case of contact lens-related Bacillus cereus keratitis and ulcer associated with B. cereus contamination of the contact lens case. This is also the first study to investigate and establish the genetic identity of an organism isolated from the cornea and contact lens
Bacillus cereus is a gram-positive, rod-shaped, beta hemolytic bacterium which rarely causes eye infections. We present a case of 15 year old boy with unilateral keratitis. He was treated for two months by his ophthalmologist who suspected herpetic keratitis. Patient most probably suffered secondary
Two patients, both contact lens wearers, were treated for acute keratitis in both eyes. Routine microbiologic tests done for all four eyes confirmed merely the presence of Staphylococcus epidermidis in the conjunctival flora; neither fungi nor any viruses were detected on the patients' corneas.
OBJECTIVE
To report the first case of Bacillus cereus keratitis leading to panophthalmitis in a patient operated for combined Descemet stripping endothelial keratoplasty (DSEK) and phacoemulsification with intraocular lens implantation.
METHODS
A 40-year-old woman with corneal decompensation
Bacillus cereus is a gram-positive aerobic or facultatively anaerobic spore-forming rod. It is a cause of food poisoning, which is frequently associated with the consumption of rice-based dishes. The organism produces an emetic or diarrheal syndrome induced by an emetic toxin and enterotoxin,
Bacillus cereus is ubiquitous in nature and thus occurs naturally in a wide range of raw materials and foodstuffs. B. cereus spores are resistant to desiccation and heat and able to survive dry storage and cooking. Vegetative cells produce several toxins which on ingestion in sufficient numbers can
