Mycobacterium ulcerans causes significant morbidity in various endemic locations in Australia and West Africa. The commonest presentation is as a necrotic ulcer often with surrounding subcutaneous necrosis and oedema, which can cause significant morbidity, deformity and functional impairment. Traditional treatment was wide excision and debridement with grafting or flap reconstructions further adding to morbidity and with high recurrence rates. Following publication of clinical studies where antibiotics were shown to be effective, treatment has moved towards combination management with systemic antibiotics and limited surgery involving mainly debridement of the ulcers. Identification of the 'paradoxical' immune-reconstitution syndrome has also impacted upon the extent of excision required. This paper will present the evolution in clinical management of M. ulcerans cases on the Bellarine Peninsula, Victoria, Australia.

, a slow-growing nontuberculous mycobacterium, causes Buruli ulcer, a neglected tropical disease. Distinguishing from related species, including , poses challenges with respect to making accurate identifications. In this study, we developed a rapid and simple identification method based on mycobacterial lipid profiles and used matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) to analyze the lipid profiles of ( = 35) and ( = 19) isolates.

Buruli ulcer (BU) a neglected disease induced by the bacterium Mycobacterium ulcerans, predominantly impacts tropical and subtropical areas with its pathophysiology ascribed to the Mycolactone protein. Current antibiotics frequently prove insufficient to manage advanced or chronic ulcers and the rise of drug resistance presents a considerable challenge. This work aims to address these challenges by employing computational methods to identify therapeutic candidates from organic compounds, which may be developed into more effective therapies for Buruli ulcer.

Mycolactone is a complex macrolide toxin produced by , the causative agent of Buruli ulcer. The aim of this paper is to review the chemistry, biosynthetic, and synthetic pathways of mycolactone A/B to help develop an understanding of the mode of action of these polyketides as well as their therapeutic potential. The synthetic work has largely been driven by the desire to afford researchers enough (≥100 mg) of the pure toxins for systematic biological studies toward understanding their very high biological activities.

We describe two locally acquired cases of Mycobacterium ulcerans infection (Buruli ulcer) in the town of Batemans Bay on the east coast of New South Wales (NSW), Australia, 150 km north of Eden, the only other place in NSW where Buruli ulcer has likely been locally acquired. Genomic analysis showed that the bacterial isolates from the cases were identical but belonged to a phylogenetically distinct M. ulcerans clade that was most closely related to the isolate from the earlier case in Eden to the south.
