Abstract Purpose

To report a case of corneal ulcer caused by Achromobacter xylosoxidans in a farmer.

 Case summary

A previously healthy 68-year-old man presented with unilateral redness and irritation after his eye was grazed by a cow's tail. The patient had previously been treated in a local clinic for four days without improvement. Bacterial staining, culture, and an antibiotic sensitivity test were performed from a corneal scrape. The cultures revealed growth of A. xylosoxidans. The patient was treated with moxifloxacin and ceftazidime eyedrops. After three months of treatment, the infection was resolved with mild scarring.

 Conclusions

Although it is a rare pathogen, A. xylosoxidans should be considered as a potential pathogen in patients presenting with corneal ulceration due to trauma from an object contaminated by soil or animal feces and having a slowly progressive disease and localized infiltrate but showing Gram-negative bacilli on smear examination.

Corneal ulcer with deep stromal infiltration and linear hypopyon were observed on initial presentation.
