Background: An ulcerative dermopathy caused by Mycobacterium ulcerans is described in two alpacas (Vicugna pacos) domiciled in endemic areas of Victoria, Australia.
Results: The diagnosis was confirmed in both cases by PCR targeting the M. ulcerans-specific insertion sequence, IS2404. Extensive wound debridement and bandaging was effective in controlling local disease in one alpaca, although the animal was eventually euthanased because of suspected disease recurrence at other anatomical sites. Treatment was not undertaken in the second animal, but the results of a complete necropsy are described. Investigation of the environs of the second animal yielded low levels of M. ulcerans DNA associated with a variety of samples. The potential use of adjunctive antibiotic therapies directed against M. ulcerans infection in this species is discussed.
Conclusion: Mycobacterium ulcerans infection should be suspected in alpacas domiciled in endemic areas and presented with ulcerative skin disease.

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.

Mycobacteria is a diverse genus that includes both innocuous environmental species and serious pathogens like Mycobacterium tuberculosis, Mycobacterium leprae, and Mycobacterium ulcerans, the causative agents of tuberculosis, leprosy, and Buruli ulcer, respectively. This study focuses on Mycobacterium marinum, a closely related species known for its larger genome and ability to infect ectothermic species and cooler human extremities. Utilizing whole-genome sequencing, we conducted a comprehensive pan-genome analysis of 100 M.
