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

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.

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.
