Abstract

PURPOSE
To report a case of corneal ulcer caused by Leclercia adecarboxylata in an immunocompetent patient.
CASE SUMMARY
A previously healthy 43-year-old female presented with right ocular pain and was referred to our clinic under the impression of corneal abrasion and secondary infection. The patient was treated at a local clinic for 3 days using artificial tears, therapeutic contact lens, topical antibiotics, and anti-inflammatory eye drops but showed no improvement. Gram staining, bacterial and fungal cultures and antibiotic sensitivity test were performed from a corneal scrape. The cultures revealed growth of Leclercia adecarboxylata. The patient was treated with moxifloxacin and ofloxacin eye drops. After 2 weeks of treatment, the infection resolved without remaining scars.
CONCLUSIONS
Reportedly, Leclercia adecarboxylata affects humans only as an opportunistic pathogen or part of polymicrobial infections. However, in the present case, Leclercia adecarboxylata was isolated as a single pathogen in an immunocompetent patient which is the first clinical report of this microorganism found in an ocular sample. Therefore, if antibiotic-susceptible gram-negative bacilli are found in opthalmologic samples, the above bacteria should be considerd in the diagnosis.
