溃疡分枝杆菌感染引起慢性皮肤溃疡（即，布鲁里溃疡病）表明，这种病原体的发展及其对人类的传播主要与水生环境有关。我们报告说，蜗牛可以短暂地窝藏M。溃疡，而不提供其生长和复制的有利条件。提出了一种新型的M.除了植食性昆虫外，溃疡病还可能与捕食性水生昆虫一起发生。水蝽属（Naucoris cimicoides）是M.在实验性地暴露于M.溃疡。
Accumulative indirect evidence of the epidemiology of Mycobacterium ulcerans infections causing chronic skin ulcers (i.e., Buruli ulcer disease) suggests that the development of this pathogen and its transmission to humans are related predominantly to aquatic environments. We report that snails could transitorily harbor M. ulcerans without offering favorable conditions for its growth and replication. A novel intermediate link in the transmission chain of M. ulcerans becomes likely with predator aquatic insects in addition to phytophage insects. Water bugs, such as Naucoris cimicoides, a potential vector of M. ulcerans, were shown to be infected specifically by this bacterium after feeding on snails experimentally exposed to M. ulcerans.
