Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

PERC produces regional and member state situation analyses, updated regularly.
The risks of the use of nuclear, radiological, biological or chemical (NRBC) weapons are heterogeneous. Each risk has its own implications for developing and deploying any capacity to assist victims of an NRBC event and, in parallel, for the health and security of the people bringing this assistance.... At an international level, there are no plans for assisting the victims of an NRBC event which are both adequate and safe. Recognizing
the realities of the contexts associated with each risk throws up numerous challenges; such recognition is also a prerequisite for addressing these challenges. The realities that have to be considered relate to:
1. developing, acquiring, training for and planning an NRBC response capacity;
2. deploying a response capacity in an NRBC event;
3. the mandates and policies of international organizations pertaining to NRBC events. The challenges that will pose the greatest difficulty for a humanitarian organization are those for which the solutions are ‘non-buyable’ and which involve making extremely difficult decisions. Attempting to assist victims of an NRBC event without a reality-based approach might generate ineffective and unacceptably dangerous situations for those involved.
