Abstract:

Bacillus cereus is a gram-positive basic, which can be sports, aerobic or facultative anaerobic, found in abundant amounts of air and soil. Bacterial keratitis is a bacterial infection disease characterized by inflammation and tissue destruction that develops as a result of the bacterial infection of the cornea. B.cereus is very rarely a keratitis factor but can cause infections that cause rapid vision loss by creating favourite destructive effects. Here, the use of contact lens, ocular surface diseases, cornea trauma, the use of immunosuppressant drugs, postocular surgery and cornea infection constitute risk factors for bacterial keratitis. In this case presentation is presented the phenomenon of keratitis occurring in the patient using a contact lens contaminated with B.cereus. When the literary data is studied, it is believed to be the first incident of keratitis from B.cereus from Turkey.The 28-year-old woman who applied to the hospital's eye clinic with a feeling of swelling in the left eye, pain and swelling, and using contact lenses, was not able to remove the lens while sleeping at night and was hit while the contact lens was in the eye about a month ago.The lens solution and eye-tracking material were sent to the microbiology laboratory for cultural purposes.The next day the bacterium was identified with the mass spectrometry (VITEK MS, bioMérieux, France) and the bacterium was found to be B.cereus.®Topical moksifloksacin eye drops (5X1), artificial tears per hour and eye powder (2X1) and 10 days after treatment, the patient found that keratitis was completely healed.

Abstract:

Bacillus cereus is a gram-positive bacillus that is abundant in air, water and soil, which can be spore, aerobic or facultative anaerobic. Bacterial keratitis is a disease of ocular infection characterized by inflammation and tissue destruction caused by bacterial infection of the cornea. Although B.cereus is rarely a causative agent of kerattitis, it can cause destructive effects in the eye and cause infections that rapidly cause vision loss. Here, contact lens wear, ocular surface diseases, corneal trauma, use of immunosuppressive drugs, postocular surgery and corneal graft are risk factors for bacterial keratitis. This case report presents a case of keratitis in a patient using contact lenses contaminated with B.cereus. Data from the literature are believed to be the first reported B.cereus induced keratitis cases from Turkey are examined. It was learned that a 28-year-old female patient who applied to our ophthalmology clinic with stinging sensation, pain and swelling in her left eye did not remove her lens at night and was beaten although she was in the contact lens eye about a month ago. Lens solution and eye swab material were sent to microbiology laboratory for culture. The next day, the bacteria were identified by mass spectrometry (VITEK MS®, bioMérieux, France) and the bacteria were identified as B.cereus. After 10 days of treatment with topical moxifloxacin eye drops (5X1), artificial tears per hour and eye pomade (2X1), keratitis was completely healed.
