Mycobacterium ulcerans mycolactones-fungi crosstalking.

ABSTRACT: The opportunistic pathogen Mycobacterium ulcerans, which is responsible for Buruli ulcer, synthesizes a series of plasmid-encoded macrolide exotoxins termed mycolactones. These toxins destabilize cell membranes and induce apoptosis-associated pleiotropic effects including tissue destruction, analgesic and anti-inflammatory effects. Despite its medical interest, M. ulcerans is primarily an environmental mycobacterium and the primary functions of mycolactones in the natural ecosystems are unknown. High throughput biochemical profiling findings suggested that M. ulcerans may interact with fungi. Here, we report that semi-purified and purified mycolactones significantly enhance spore germination of Scedosporium apiospermum, Fusarium equiseti and Mucor circinelloides; and that M. ulcerans mycol
