“…Int I, as an important carrier for ARG transfer, was also prevalent in our results, with a relative abundance of 0.015. Int I has been frequently detected in diverse environments, including pharmaceutical wastewater, municipal wastewater, natural water, and livestock wastewater (Igbinosa & Okoh, ; Yin, Yue, Peng, Liu, & Xiao, ). Up to 31% and 68% of bacteria isolated from fish farm and pig farm were reported to carry int I, 86.7% of which also contained sul I (Melendez et al., ; Ndi & Barton, ).…”

This study explores the prevalence, emission, and reduction of five ARGs (sulI, tetA, mphB, qnrD, and mcr‐1) and integron (intI) through a distributed swine wastewater purification facility and the effluent‐receiving environment. Typical metal resistance genes (MRGs), pathogenic bacterial indicators, the bacterial community, and wastewater properties were also explored to determine their effects on the fates of ARGs. Results indicated that the purification process could hardly effectively remove ARGs’ prevalence. 3.1 × 104–7.1 × 108 copies/L were present after purification, and 4%–57% of them persisted in the subsequent creek and adjacent soil. 16S rRNA sequencing suggested that the discharge of wastewater significantly changed the bacterial community in receiving creek and soil. Molecular ecological networks analysis detected the wide co‐occurrence among ARGs, MRGs, and PBGs, which could further facilitate the propagation of antibiotic resistance. ARG incidence and specific bacterial genera were closely correlated, suggesting an extensive hosting relationship. Redundancy analyses showed wastewater organics and nutrients showed positive correlation to most ARGs’ abundance, but negatively correlated to their relative abundance. Practitioner points Fate of five ARGs and intI was studied in a swine wastewater treatment system. The treatment process could not effectively reduce ARGs’ abundance. ARGs and pathogens in wastewater were transferred to the receiving creek and soil. The network analysis found wide co‐occurrence among ARGs, metal resistance genes, and pathogens. Wastewater nutrients positively correlated to ARG's abundance but negatively correlated to their relative abundance.

“…Horizontal gene transfer "hot spots" in the environment are characterized by elevated microbial and nutrient levels, including the pore water of soil/sand particles and biofilms (Gaze et al 2013). Among studies performed on horizontal gene transfer in bacteria isolated from water, Yin et al (2013) observed transfer of antibiotic resistance genes from several host genera, including Pseudomonas and Acinetobacter to E. coli, but more information on horizontal gene transfer in sand and other beach environments will be required to determine the importance of these environmental reservoirs to human health.…”

Humans may be exposed to microbial pathogens at recreational beaches via environmental sources, such as water, sand, and aerosols. Although infectious disease risk from exposure to waterborne pathogens has been an active area of research for decades, sand is a relatively unexplored reservoir of pathogens and fecal indicator bacteria (FIB). Beach sand and water habitats provide unique advantages and challenges to pathogen introduction, growth, and persistence, as well as continuous exchange between habitats. Models of FIB and pathogen fate and transport in sandy beach habitats can help predict the risk of infectious disease from recreational water use, but filling knowledge gaps such as decay rates and potential for microbial growth in beach habitats is necessary for accurate modeling. Climatic variability, whether natural or anthropogenically-induced, adds complexity to predictive modeling, but may increase human exposure to waterborne pathogens via extreme weather events, warming of water bodies and sea level rise in many regions. The popularity of human recreational beach activities, combined with predicted climate change scenarios, could amplify the risk of human exposure to pathogens and related illnesses. Other global change trends such as increased population growth and urbanization are expected to exacerbate contamination events and the predicted impacts of increasing levels of waterborne pathogens on human health. Such changes will alter microbial population dynamics in beach habitats, and will consequently affect the assumptions and relationships used in population models and quantitative microbial risk assessment (QMRA). Here, we discuss the literature on microbial population and transport dynamics in sand-water continuum habitats at beaches, how these dynamics can be modeled, and how climate change and other anthropogenic influences (e.g., land use, urbanization) should be considered when using and developing more holistic, beachshed-based models.
