Listeria monocytogenes endophthalmitis
Abstract:
Listeria monocytogenes and a staphylococcus organism caused a catastrophic endophthalmitis in a patient despite appropriate local and systemic antimicrobial chemotherapy. Although L monocytogenes is widespread in nature and has produced a variety of clinical illnesses, it has only one previously been reported to cause endophthalmitis. If appropriate microbiologic techniques are not employed, the organism may go unrecognized as an ocular pathogen.
Insights
Listeria monocytogenes and Staphylococcus caused severe endophthalmitis, a rare ocular infection. Prompt microbiologic identification is crucial for recognizing Listeria monocytogenes as an ocular pathogen.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Microbiology
Background:
- Endophthalmitis is a severe intraocular infection.
- Listeria monocytogenes is a known pathogen but rarely causes endophthalmitis.
- Staphylococcus species are common causes of endophthalmitis.
Purpose of the Study:
- To report a rare case of catastrophic endophthalmitis caused by Listeria monocytogenes and Staphylococcus.
- To highlight the importance of microbiologic techniques in identifying ocular pathogens.
Main Methods:
- Case report detailing clinical presentation and treatment.
- Microbiologic analysis of intraocular fluid.
Main Results:
- Successful identification of Listeria monocytogenes and Staphylococcus as causative agents.
- Despite treatment, the patient experienced a catastrophic outcome.
Conclusions:
- Listeria monocytogenes can cause severe endophthalmitis, even with appropriate antimicrobial therapy.
- Specialized microbiologic techniques are essential for diagnosing Listeria monocytogenes endophthalmitis.
- Early and accurate identification of the causative organism is critical for managing endophthalmitis.
