An adipose cell (SW872) model was developed to observe cellular necrosis an
d apoptosis upon Mycobacterium ulcerans infection and treatment with mycoba
cterial exudate. Apoptosis was likely due to secreted proteins, while necro
sis was likely due to mycolactone. Our data suggest that additional factors
in AT. ulcerans may be involved in Buruli ulcer pathogenesis.
