You are a clinical lab scientist working in a microbiology lab in a large urban hospital.
Patient: Nancy S.
Approximately one month after a successful keratectomy, a 62 year old female presented to her ophthalmologist with severe eye pain and deteriorated vision.
The patient had a history of Alzheimer's disease, excessive hand to mouth contact, and scratching her eyes aggressively. She lived in a group home with other adults and a dog. The patient reportedly allowed the dog to lick her face profusely. Hygiene in the facility was reported to be less than adequate and rodents were suspected to be a problem. After examination, the patient was admitted to the hospital and a vitrectomy was performed.
Case objectives:
1. Based on patient history, the student will propose appropriate specimens and tests to assist in the diagnosis.
2. Examine and interpret Gram stain and culture results to narrow the range of possible pathogens.
3. For the organism identified, suggest appropriate antimicrobial susceptibility testing methods and reporting of results.
Before you begin, please contribute to the research surrounding case stories by answering a few questions.
