Mycobacterium ulcerans - Now Available

The extensive collection of Mycobacterium species available from BEI Resources continues to grow with the addition of M. ulcerans, the cause of a neglected tropical disease known as Buruli ulcer that causes cutaneous lesions and osteomyelitis.1,2,3 M. ulcerans has been identified in 33 countries worldwide, most commonly in Africa, and typically occurs in wetland and tropical regions and in areas with recent environmental change.2 M. ulcerans contains a virulence plasmid encoding for the production of mycolactone, a macrocyclic polyketide toxin with cytotoxic and immunosuppressive activity.

The available and upcoming isolates were collected from clinical cases of Buruli ulcer in Benin, where over 6,000 Buruli ulcer cases were reported between 2006 and 2015.4
