Ballast water is a primary vector for the global transfer of non-indigenous species, which threaten the balance of aquatic ecosystems. The second-generation high-throughput sequencing (HTS) and culture method (by the first-generation sequencing technology) were used to explore pathogens in ballast water from international ships on the routes of China-Australia (AU), China-Europe (E) and China-America (AM). No significant differences in dominant bacteria among ballast water samples from different routes. Thirty-four pathogens were detected in all samples by HTS, including Acinetobacter lwoffii, Brevundimonas vesicular and Pseudomonas sp., etc., while nine pathogens were detected by culture, including Pseudoalteromonas piscicida, Rhodococcus erythropolis and Vibrio alginolyticus, etc. All ballast water carried a potential bacteriological risk to Yangshan Port. The abundance of pathogens was significant affected by holding time, temperature, salinity and NH₄. Detection of pathogens as much as possible through different technologies is desirable, more pathogens could provide beneficial information for enhancing ballast water management.
