Host–parasite interactions are often embedded within complex host communities and can be influenced by a variety of environmental factors, such as seasonal variations in climate or abiotic conditions in water and soil, which confounds our understanding of the main drivers of many multi-host pathogens. Here, we take advantage of a combination of large environmental data sets on  Mycobacterium ulcerans  ( MU ), an environmentally persistent microorganism associated to freshwater ecosystems and present in a large variety of aquatic hosts, to characterize abiotic and biotic factors driving the dynamics of this pathogen in two regions of Cameroon. We find that  MU  dynamics are largely driven by seasonal climatic factors and certain physico-chemical conditions in stagnant and slow-flowing ecosystems, with an important role of  pH  as limiting factor. Furthermore, water conditions can modify the effect of abundance and diversity of aquatic organisms on  MU  dynamics, which suggests a different contribution of two  MU  transmission routes for aquatic hosts (trophic vs environmental transmission) depending on local abiotic factors.

Mycobacterium ulcerans dynamics in aquatic ecosystems are driven by a complex interplay of abiotic and biotic factors
