Abstract

Temperate estuary wetlands act as natural filters for microbiological contamination and have a profound impact on "One Health." However, knowledge of microbiological ecology security across the different habitats in temperate estuarine wetlands remains limited. This study employed meta-analysis to explore the characteristics of bacterial communities, potential pathogens, and antibiotic resistance genes (ARGs) across three heterogeneous habitats (water, soil, and sediment) within the Liaohe Estuary landscape. The diversity and composition of the three bacterial communities differed with biogeography, temperature, and pH, with the highest α-diversity showing a significantly negative correlation along latitude in soil. Furthermore, aminoglycosides were significantly enriched in water and soil, while dihydrofolate was more likely to be enriched in soil. The potential pathogens, Pseudoalteromonas and Planococcus, were dominant in water and sediment, while Stenotrophomonas was the dominant bacterium in soil. The network topology parameter revealed interspecific interactions within the community. PLS-PM highlights the main direct factors affecting the abundance of potential pathogens and the spread of ARGs, while temperature and pH indirectly influence these potential pathogens. This study advances our understanding of bacterial communities in estuarine wetlands, while highlighting the need for effective monitoring to mitigate the risks associated with potential pathogens and ARGs in these ecosystems.
