Summary: Widely distributed multidrug-resistant bacteria pose a threat to animal and human health, but there have been few surveys on the antimicrobial resistance of large-scale animal-derived bacteria. A study in Zhejiang Province, China, found that Escherichia coli strains isolated from pig and chicken anal swab samples showed high resistance to multiple antibiotics, and some strains carried resistance genes against last-resort antimicrobials. Furthermore, a correlation between heavy metals and antibiotic resistance was observed.

Summary: Multidrug-resistant Escherichia coli isolates recovered from aquatic ecosystems showed resistance to extended-spectrum cephalosporins, polymyxins, and fluoroquinolones. Multiple antimicrobial resistance genes and metal tolerance genes were found. Additionally, virulence genes and genetic diversity were present among these isolates. The emergence of multidrug-resistant and metal-tolerant potentially pathogenic E. coli strains at the human-animal-environment interface is a global health concern.

Summary: The study found that different E. coli strains vary in their ability to acquire and maintain MDR plasmids, with highly strain-specific transcriptional responses observed following plasmid acquisition. However, the subtle transcriptional responses consistent across all strains suggest that fitness costs arising from transcriptional disruption are unlikely to act as a barrier to dissemination of this MDR plasmid in E. coli.

Summary: The gastrointestinal tracts of dairy calves and cows are reservoirs of antimicrobial-resistant bacteria. Young calves harbor a greater abundance of resistant bacteria than older cows, but the factors driving this high abundance are unknown. This study aimed to characterize multidrug-resistant (MDR) and antimicrobial-susceptible Escherichia coli strains isolated from different stages of dairy cows and identify accessory genes associated with MDR to discover genetic targets for mitigating antimicrobial resistance on dairy farms.

Summary: This study investigated the antimicrobial resistance profile of ESBL-producing E. coli among food-producing animals in Tamaulipas, Mexico. A total of 200 fecal samples were collected and 5.0% of the strains were confirmed as ESBL producers. High percentage of antimicrobial resistance was observed against gentamicin, tetracycline, and streptomycin. The study suggests that food-producing animals may serve as reservoirs and contribute to the spread of ESBL-producing bacteria.

Summary: Antibiotic resistance is a major public health challenge, and efforts to address it have mainly focused on drug development and reducing unnecessary antibiotic use. However, in areas with poor water, sanitation, and hygiene infrastructure, bacterial transmission between humans and animals can worsen the emergence and spread of resistant pathogens. In Cambodia, a middle-income country with high human-animal connectivity and unregulated antibiotic use, identical mobile resistance elements were found in both humans and animals, which is rare in high-income settings. The study suggests that controlling the transmission of resistant bacteria at the human-animal interface is crucial in addressing antibiotic resistance in low- and middle-income countries.

Summary: Analysis of food samples collected at retail stores in Beijing, China, showed high contamination levels of E. coli and enterococci in food-animal products, vegetables, aquatic products, and fruits, with significant multidrug resistance. Food-animal products were identified as the primary reservoir of antimicrobial resistance, while the role of vegetables, fruits, and aquatic products in spreading AMR should not be underestimated. Food-borne isolates displayed high resistance to antibiotics commonly used in agriculture, as well as those rarely used in agriculture/aquaculture, highlighting the potential for animal-to-human transmission of antibiotic resistance genes.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.
