What is the incubation period of Buruli ulcer?
Results: Among the 20 new cases identified in short-term visitors, the mean incubation period was 143 days (4.8 months), very similar to the previous estimate of 135 days (4.5 months). This was despite the predominant exposure location shifting from the Bellarine peninsula to the Mornington peninsula.
Why are Buruli ulcers painless?
This is the first study to demonstrate the systemic effects of mycolactone. Buruli ulcer is a chronic painless skin disease caused by Mycobacterium ulcerans (12, 14). M. ulcerans produces a toxic lipid, mycolactone, that induces apoptosis in guinea pig lesions, as well as in human patients (6, 13).
