Summary: Fecal indicator bacteria (FIB) are monitored to assess water quality and health risk at beaches, but infrequent monitoring can lead to inaccurate assessments. This study conducted high-frequency FIB sampling at an enclosed harbor in California, showing more variability in FIB concentrations compared to open beach sites. Correlation and regression analyses revealed strong associations between FIB concentrations and chlorophyll a, turbidity, wind speed, and tide level. The study emphasizes the importance of sampling FIB concentrations and environmental parameters at appropriate temporal resolutions for water quality monitoring.

Summary: This study revealed the levels of antimicrobial resistance (AMR) in European pig and broiler farms and identified potential risk factors. Real-time quantitative PCR (qPCR) was used to assess the relative abundance of four antimicrobial resistance genes (ARGs) in fecal samples. The study found a significant association between ARG abundance and antimicrobial use (AMU) levels, as well as the impact of on-farm biosecurity measures on ARG abundance. Variance component analysis showed that AMR variation was primarily influenced by differences between countries, farms, and on-farm AMU.

Summary: The research demonstrates that the survival of fecal indicator bacteria, pathogenic microorganisms, and other bacterial and viral surrogates in freshwater differs by sample type (sediment/water) and season. There is a greater microbial persistence in sediments than in water over time, with differences in survival among microorganisms in relation to the fecal indicator bacteria E. coli and enterococci. Further investigation is needed to determine the best surrogates to assess pathogen survival in agricultural water for fresh produce.

Summary: Beach sand and water are both important for human health and their microbiology has been studied for decades. The World Health Organization recently recommended including recreational beach sands in monitoring for enterococci and Fungi. Global climate change is affecting beach microbial contamination, and the changing world and human travel contribute to the spread of endemic allochthonous microbiota. In the future, alternative microbial standards will be necessary to ensure the health of beach users from both sand and water contaminants.

Summary: Afforestation can effectively rehabilitate degraded ecosystems, but it may deplete deep soil moisture, which in turn affects soil microbial community and functionality. This study found that afforestation significantly impacted soil bacterial community and functionality in a semi-arid region of China's Loess Plateau, particularly in the deep soil layers. Afforestation led to reduced bacterial diversity and functionality, increased sensitivity to changes in soil moisture, and decreased sustainability of the ecosystems. These negative impacts on deep soils are crucial for assessing the eco-environmental effects of afforestation and ensuring the sustainability of forest ecosystems in semi-arid and arid climates.
