An overview of Buruli ulcer in Australia

BU can manifest as an ulcer or as a non-ulcerated skin lesion, such as a plaque, nodule or oedema. Diagnosis can be achieved with a dedicated Mycobacterium ulcerans polymerase chain reaction (PCR) test performed on a wound swab. Swabs on non-ulcerated disease have a high false negative rate, and a PCR test should be performed on a tissue biopsy to confirm disease. Most cases are managed with prolonged antibiotic therapy - commonly a combination of oral rifampicin and clarithromycin or fluroquinolone (moxifloxacin or ciprofloxacin) - and wound dressings.
