Abstract
Long-range dispersals of marine bacteria in the oceans have remained largely indecipherable, which is particularly relevant for Vibrio, responsible for global epidemics in humans and animals. Here, we combine the analysis of 40 terabases of metagenomic data and satellite-tracked surface drifter data, from across the globe revealing that Vibrio are abundant members of the ocean surface and show a strong association with microplankton, which appears to govern their distribution and connectivity at a global scale. We identify long-distance biological corridors connecting Vibrio communities, including potentially pathogenic Vibrio. These corridors allow movement over thousands of kilometres in a fairly short time, with estimates of less than 1.5 years to cross an ocean basin. These findings have deep implications for the demography and community dynamics of Vibrio species and the epidemiology of associated diseases.
