“…Currently, antibiotics are extensively utilized not only in the medical domain but also in sub-therapeutic doses for prolonged periods in fields such as agriculture, forestry, animal husbandry, and fisheries on a global scale. However, the abuse and misuse of antibiotics have led to their excessive overdose being detected many times in surface water, groundwater, and soil worldwide [ 24 , 25 ]. In farming activities, some small and medium-sized farmers have poor awareness of standardized medication use, and the abuse of antibiotics exists more often.…”

Antimicrobials are extensively utilized in dairy farms to prevent and control diseases in cattle. However, their use contributes to the emergence of antimicrobial-resistant bacteria (ARB) and antimicrobial-resistant genes (ARG), and these can be transmitted to the environment. Regular monitoring of antimicrobial resistance (AMR) is crucial for implementing effective mitigation strategies. This research aimed to assess the environmental microbial species present on dairy farms in Shandong Province and characterize the antimicrobial resistance profiles of the isolates. Five dairy farms located in Shandong Province were selected, representing the prevalent large-scale farming patterns in the area. Sampling took place from April to June 2022, with a total of 223 isolates collected from various environmental locations within each farm (bedding, sports field, and milking parlor). Matrix-assisted laser desorption/ionization—time-of-flight mass spectrometry (MALDI-TOF MS) was employed to identify the species of the clinical isolates. The main pathogens isolated were Aerococcus viridans (5.38%, n = 12), Corynebacterium xerosis (4.93%, n = 11), and Acinetobacter lwoffii (4.03%, n = 9). Among the bacterial isolates, resistance to lincomycin was highest at 91%, and 88% were resistant to sulfadiazine. Antimicrobial resistance genes were detected in only a small proportion of the isolates, the most common of which was sul1. These findings highlight the necessity for careful evaluation of antimicrobial usage in maintaining their effectiveness in human medicine. Understanding the microbial species present and their antimicrobial resistance profiles aids in focusing efforts toward sustainable antimicrobial use and safeguarding human health.

“…Antibiotics are chemotherapeutic agents developed to inhibit or kill bacteria for the curing of infections . Tetracycline (TC), one of the broad-spectrum antibiotics, has been widely used in medicine for both human and animal treatments, as well as in aquaculture. , However, as a result of overuse and misuse, TC has recently been discovered in water bodies as an emerging contaminant, which in turn requires significant efforts for mitigation. , It has been proven that TC accumulated in the environment poses a potential hazard to human health and ecological balance due to the spread of specific and multiple resistances. − Various approaches have been proposed to mitigate the accumulation of TC in aquatic ecosystems, such as adsorption, membrane filtration, , hydrolysis, and so on, − which still face some problems such as low efficiency and high cost for treatment.…”

Peroxymonosulfate (PMS) activated by metal oxides has been developed as a promising approach for advanced oxidation processes in the treatment of antibiotic containing wastewater; however, rapid and effective activation of PMS still lacks reasonable catalyst-oriented design. Here, by fabricating a Co 3 O 4 −La 2 O 3 bimetallic oxide electrode to implement defect engineering, we report an oxygen vacancy (OV)-mediated PMS activation electrocatalytic system for degradation of tetracycline (TC). The rare earth metal oxide La 2 O 3 was used to modify Co 3 O 4 and introduce OVs as active sites, where PMS is activated to produce reactive species. OVs in the Co 3 O 4 −La 2 O 3 composites facilitate the generation of singlet oxygen ( 1 O 2 ), which mediates the activation of PMS via a non-radical pathway. When the ratio of Co to La was 2:1, the system Co 3 O 4 −La 2 O 3 /PMS had a degradation efficiency for TC of more than 97.50% and a mineralization rate of up to 62.97% within 40 min. Overall, the findings on the defect-engineered materials for antibiotic degradation could provide an effective strategy for the treatment of antibiotic containing wastewater with low energy consumption and pollution.
