Abstract

We report urinary tract infection caused by Citrobacter braakii in an 83-old female patient with chronic kidney disease. The isolate was confirmed with bacteria analytical profile index and MALDI-TOF identification methods. A urine sample was presented to the lab for investigating urinary tract infection along with blood biochemistry and whole blood picture investigation. Antimicrobial susceptibility tests were carried out based on the Clinical and Laboratory Standards Institute’s guidelines and the isolate was resistant to ampicillin and amoxycillin clavulanate.

Keywords: amoxicillin clavulanate resistance, amoxicillin resistance, API, chronic kidney disease, Citrobacter braackii, elderly female patient, MALDI-TOF, urinary tract infection.
