PURPOSE: Enterococcus faecalis causes severe acute endophthalmitis and often leads to poor visual outcomes. Conjunctival bacterial cultures occasionally grow atypical bacteria including E. faecalis, which can potentially contribute to the development of postoperative endophthalmitis. However, the characteristics of these ocular E. faecalis strains are unknown. This study is the first attempt to determine the population characteristics of E. faecalis clinical isolates from eye infections and ocular commensals...

Enterococcus gallinarum and Enterococcus casseliflavus/flavescens are enterococci intrinsically resistant to vancomycin belonging to the E. gallinarum group. They are responsible mainly for healthcare-associated infections, in particular bloodstream, urinary tract and surgical wound infections. Diseases due to these bacteria are significantly increasing worldwide, as they are prone to cause infection in patients with concurrent hepatobiliary or oncohematological disorders. Along with their distinguishing vancomycin resistance, due to a chromosomally-encoded VanC operon, their additional intrinsic resistance to many antibiotics other than glycopeptides limits the therapeutic choices...

BACKGROUND: Endophthalmitis is a rare but severe complication following PPV. The incidence of endophthalmitis varies between 20-gauge, 23-gauge, and 25-gauge incisions. The incidence and clinical features of endophthalmitis after 23-gauge PPV in an eye hospital in China was reported in this study. METHODS: Data of the eyes that underwent 23-gauge PPV from January 2011 to December 2014 at the Eye Hospital of Wenzhou Medical University was retrospectively collected...

Intraocular infections are a potentially blinding complication of common ocular surgeries and traumatic eye injuries. Bacterial toxins synthesized in the eye can damage intraocular tissue, often resulting in poor visual outcomes. Enteroccocus faecalis causes blinding infections and is responsible for 8 to 17% of postoperative endophthalmitis cases. These infections are increasingly difficult to treat due to the emergence of multidrug-resistant strains. Virulent E. faecalis isolates secrete a pore-forming bicomponent cytolysin that contributes to retinal tissue damage during endophthalmitis...

PURPOSE: To report Enterococcus faecalis endophthalmitis (EFE) in children and its comparison with adults. METHODS: Retrospective study of 19 children up to 18 years age, undergoing vitrectomy for EFE at a referral eye center from January 1995 to December 2015. The results were compared to 18 adults with EFE. RESULTS: The mean age was 7.4 ± 3.06 years. Post-traumatic EFE was seen in 17 (89.4%) children (p < 0.05) versus postoperative EFE seen in 12 (66%) adults...

Purpose Postoperative endophthalmitis caused by Enterococcus faecalis often results in poor visual outcome due to retinal destruction. We evaluated the virulence factors of Enterococcus faecalis clinical isolates and analyzed their relationship with retinal destruction and poor visual outcomes in postoperative bacterial endophthalmitis (PBE) following cataract surgery. STUDY DESIGN: Retrospective. METHODS: E. faecalis isolates from nine acute-onset PBE cases were examined using pulsed-field gel electrophoresis of genomic DNA, plasmid isolation and pheromone response experiments...

A 68-year-old woman presented with infectious crystalline keratopathy 4 months after she underwent a combined phacoemulsification and Descemet's stripping endothelial keratoplasty for Fuch's endothelial dystrophy in her left eye. After 5 months of topical moxifloxacin 1%, the infiltrate responded well but had not completely resolved, with the resulting endothelial failure requiring a penetrating keratoplasty 9 months after the initial operation. Microbiology identified Enterococcus faecalis with the histopathology demonstrating bacterial colonies within the graft interface...

PURPOSE: To report a case of acute bacterial endophthalmitis after antivascular endothelial growth factor injection with a rare presentation of vitreous hemorrhage. METHODS: An 84-year-old woman presented with sudden painless vision loss in her left eye, 3 days after intravitreal ranibizumab injection for cystoid macular edema due to neovascular age-related macular degeneration. The patient was otherwise asymptomatic. Dense vitreous hemorrhage was observed. At follow-up the next day, the patient complained on severe left eye pain...

BACKGROUND: Identification of bacterial pathogens in endophthalmitis is important to inform antibiotic selection and treatment decisions. Hemoculture bottles and polymerase chain reaction (PCR) analysis have been proposed to offer good detection sensitivity. This study compared the sensitivity and accuracy of a blood culture system, a PCR approach, and conventional culture methods for identification of causative bacteria in cases of acute endophthalmitis. METHODS: Twenty-nine patients with a diagnosis of presumed acute bacterial endophthalmitis who underwent vitreous specimen collection at King Chulalongkorn Memorial Hospital were enrolled in this study...

PURPOSE: Intracameral cefuroxime (CXM) and antibiotic eye drops such as fluoroquinolone are widely used for preventing endophthalmitis after cataract surgery. However, few reports are available regarding their interactions. This study was conducted to examine the in vitro interaction of CXM and levofloxacin (LVFX) against bacterial isolates from the healthy conjunctival sac before cataract surgery and from endophthalmitis cases. METHODS: The activity of each drug was determined using a broth dilution method...

A man aged 77 years with postrenal transplant lymphoproliferative disease was admitted with high fever, elevated inflammatory markers and a heart murmur. Blood cultures grew Enterococcus faecalis and he was found to have mitral valve endocarditis on echocardiogram and subsequently started on appropriate antibiotics. 5 days into treatment, he developed ocular symptoms and 3 days later, he had irreversible monocular visual loss. He was seen by the ophthalmology team who diagnosed endogenous endopthalmitis secondary to bacteraemic spread from his endocarditis...
