Summary
This study reports the first case of feline endogenous bacterial endophthalmitis caused by Enterococcus faecalis. Despite treatment, the cat experienced permanent vision loss from the severe eye infection.
Area of Science:
- Veterinary Ophthalmology
- Infectious Diseases in Cats
- Microbiology
Background:
- Endogenous bacterial endophthalmitis is a severe intraocular infection.
- Feline uveitis can have various causes, including infectious agents.
- Early diagnosis and treatment are crucial for preserving vision.
Observation:
- A three-year-old domestic shorthair cat presented with vision loss, hyperthermia, lethargy, and anorexia.
- Ophthalmic examination revealed bilateral panuveitis.
- Cytology and bacterial culture identified Enterococcus faecalis in the aqueous and vitreous humours.
Findings:
- The case involved suppurative inflammation and cocci in the ocular fluids.
- Enterococcus faecalis was confirmed as the causative agent.
- No primary infection site was identified in the cat.
Implications:
- This is the first reported case of endogenous bacterial endophthalmitis secondary to E. faecalis in a cat.
- Systemic antibiotic therapy resolved the active uveitis but not the vision loss.
- Highlights the potential for severe ocular consequences from systemic E. faecalis infections in cats.

01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:25Endocarditis I: Introduction
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...
01:26Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic
Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies. Common...
