Summary: This study developed a comprehensive tool for assessing global antimicrobial resistance (AMR) status and evaluated AMR in 146 countries. The study found that high-income countries performed better in terms of AMR, while low-income countries unexpectedly performed well in certain indicators. The study also identified correlations between AMR and socioeconomic factors such as GDP and life expectancy.

Summary: Marine mammal strandings provide important information on species' life histories, population health, and the status of marine ecosystems. The study analyzed data over 270 years and found an increasing trend in strandings along the Indian coast. Peak stranding events were observed from June to September on the west coast and from December to January on the east coast. Several sections of the coastline were identified as hotspots with higher numbers of stranded animals reported. The study recommends establishing regional stranding response centers at these hotspots and maintaining a national stranding database for long-term marine mammal conservation planning.

Summary: Aquaculture is crucial for food security and nutrition, with salmonids being an important source of protein and nutrients. However, challenges such as fish diseases and antibiotic resistance in Chilean salmon farming need to be addressed urgently. Efforts to reduce antibiotic use in aquaculture are necessary to prevent the spread of resistant bacteria and protect human and environmental health.

Summary: This study evaluated the seasonal and temporal trends of blubber thickness in harbor seals, grey seals, and harbor porpoises in the southern Baltic Sea. The effects of age, season, and sex were analyzed as well. The findings indicated significant seasonal variations in blubber thickness for all species, with fluctuations over the years for harbor seals and porpoises included in the analysis.

Summary: This study investigated the accumulation of inorganic contamination in clam tissues over a five-year period and examined changes in physiological health indicators. The results showed that the level of contamination differed between polluted sites and the site with no known pollution source. The contaminants were found to be from particulate combustion products of gasoline/diesel, crude oil, and urban pollution. Clams at the polluted sites had reduced condition factor, growth index, and air survival time, while clams at the site with increased contamination showed decreased condition factor and increased dehydration rate.

Summary: In the post-antibiotic era, the rapid development of antibiotic resistance and the shortage of available antibiotics have created a new health-care crisis. Small-molecule antimicrobial peptides, with their rich structural diversity and innovative antimicrobial mechanisms, have emerged as promising candidates for next-generation antibiotics. In this article, we present a collection of small-molecule antimicrobial peptides derived from marine microorganisms over the past fifteen years, categorizing them into three classes based on their structural features. We provide information on their sources, structures, and antimicrobial spectrums, as well as discussing the structure activity relationships and mechanisms of action of some compounds.

Summary: This study aimed to monitor antimicrobial resistance in companion animals in the UK, finding that the most commonly isolated bacteria in dogs and cats were Escherichia coli, with some bacteria showing resistance to multiple drugs. Genotypic characterization proved to be an efficient method for identifying important resistance trends in companion animals on a national scale.

Summary: Water, sanitation, and hygiene (WASH) factors play a crucial role in the transmission of extended-spectrum beta-lactamases (ESBL)-producing Escherichia coli, while antimicrobial exposure is the key driver for ESBL-producing Klebsiella pneumoniae.

Summary: Antimicrobial resistance poses a significant threat to global public health, with causes attributed to various factors such as human activities, animal practices, and environmental conditions. Misuse and overuse of antimicrobials in medicine, agriculture, and animal feed, along with inadequate sanitation and hygiene, contribute to the emergence and spread of resistance. A one-health approach involving proper antimicrobial use, improved sanitation, and coordinated governmental regulations is crucial in combating antimicrobial resistance, with collaboration among stakeholders from public, veterinary, and ecological health sectors being paramount.

Summary: This study aimed to identify the pathogens, genes, and antimicrobial residues present in raw milk and meat. Samples were collected from different parts of Faisalabad metropolis in Pakistan. The beef samples showed polymicrobial contamination with Escherichia coli and Klebsiella pneumoniae predominating, while the milk samples showed polymicrobial contamination with E. coli, K. pneumoniae, and Staphylococcus aureus forming the majority. Antimicrobial resistance genes were identified in both beef and milk samples, with high tetracycline residue levels posing a serious health risk to consumers.

Summary: A study in North-central Nigeria assessed fish farmers' practices and perceptions on antimicrobial usage, as well as risk pathways for antimicrobial resistance. Findings revealed widespread self-prescription of antimicrobials and lack of adherence to withdrawal periods, with socio-cultural drivers contributing to misuse and emergence of resistance. Majority of farms were classified as high risk, with residues detected in samples from nearly half of the farms. Promotion of antimicrobial stewardship and control programs are necessary to address these issues for food safety and public health.

Summary: This study investigated the mechanism of action and therapeutic potential of an antimicrobial peptide derived from a marine polychaete. The peptide exhibited strong activity against bacterial pathogens, including drug-resistant strains, and could prevent and destroy bacterial biofilms. With low toxicity towards mammalian cells, it holds promise as a potential scaffold for the development of drugs to treat chronic E. coli infections.

Summary: Microbial-driven nitrogen removal is crucial in full-scale wastewater treatment plants (WWTPs), and understanding the nitrogen cycling networks is essential for optimizing these processes. This study used metagenomics and metatranscriptomics to investigate the microbial nitrogen removal processes in a full-scale WWTP. The study found a simultaneous nitrification-anammox-denitrification (SNAD) process, where ammonia was oxidized by AOB, AOA, and NOB, and the resulting nitrite and nitrate were reduced to N2 by anammox and denitrifying bacteria. The study also identified specific anammox bacteria and highlighted their potential for efficient nitrogen removal.
