An 11-month-old girl presented with metastatic endophthalmitis. The causative organism was the Gram-negative coccobacillus Kingella kingae. This is an uncommon organism first recognised in 1967. It has never been previously reported to cause endophthalmitis, but is associated with at least four other infective syndromes in children. Endophthalmitis is a potentially lethal and sight-threatening disease. Kingella kingae is primarily a paediatric pathogen which fortunately responds well to antibiotics. A case study, details of the bacteriology and a table of other clinical syndromes associated with this organism seen at our institution constitute this article. (12 references).
