Achromobacter xylosoxidans infection in urinary tract in a secondary kidney stone patient: Case Report

Abstract

Achromobacter xylosoxidans formerly named as Alcaligenes xylosoxidans is an aerobic, non-fermenting, oxidase positive, catalase positive gram negative bacillus. It is seen especially in immunosuppressed patients, patients with tumors, hypogamaglobulinemia or transplant patients. A. xylosoxidans infection in urinary system is very rare. 56 year old male patient was presented to our clinic with bilateral flank pain. He had not immunodeficiency and tumor history. He had diabetes mellitus. He had shock wave lithotripsy history for bilateral kidney stone. He had previous open surgery for right kidney stone and retrograde intrarenal surgery for left kidney stone. In the urine culture, Achromobacter xylosoxidans infection was detected. Ciprofloxacin, ceftriaxone and methenamine hippurate treatment were firstly applied to the patient. Patient was followed and 15 days later he admitted our clinic. 38 white blood cells and 8 red blood cells were present in urinalysis and the control urine culture was sterile. In conclusion, A. xylosoxidans infection is rarely seen and it has high resistance to antibiotics. Clinicians must be careful about the infection and treatment of A. xylosoxidans infection.
