Buruli Ulcer - Diagnosis

Diagnosis

The diagnosis of Buruli ulcer is usually based on the characteristic appearance of the ulcer in an endemic area. If there is any doubt about the diagnosis, then PCR using the IS2404 target is helpful, but this is not specific for M. ulcerans. The Ziehl-Neelsen stain is only 40–80% sensitive, and culture is 20–60% sensitive. Simultaneous use of multiple methods may be necessary to make the diagnosis.
