Diseases are responsible for losses in livestock production by increasing animal mortality and reducing productivity. The administration of antibiotics can help mitigate these negative effects. However, inappropriate use lead to severe complications, such as raising antibiotic resistance. purpose this study was perform a comparative analysis disease frequency over four years, based on the size dairy farms type farm. covered 4-year period included medium (20–50 cows, n = 13), large (>250 8), beef (n 8). collected data involved antimicrobial but also farm demographics, health, frequency, herd management practices. criteria used categorise into groups A–D were EMA guidelines. carried-out showed that cattle had highest consumption (18.29 mg·PCU−1), due high diseases, consequently, treatment calf (diarrhoea, lung inflammations) cow diseases (general mastitis). Cattle suffer mainly from general caused maintenance conditions. restrict was, some cases, unjustified (antibiotics dry therapy). Future studies should consider larger number farms, taking account given direction production.

Intensive fish farming worldwide has increased reliance on antibiotics to control bacterial pathogens, raising concerns about antimicrobial resistance (AMR) in aquaculture. These resistant bacteria can persist and pass through the food supply chain, from farms consumers. Despite this risk, genes (ARGs) aquaculture environments products have not been elucidated. This study aimed detect ARGs found Asian seabass (Lates calcarifer), an economically important Thailand, collected farms, container vehicles, markets, using Nanopore metagenomic sequencing. We detected multiple all sample types. Water samples harbored rpsL gene conferring streptomycin resistance. Container exhibited highest diversity of ARGs, including beta-lactamases rsmA gene, fluoroquinolones, diaminopyrimidines, phenicol antibiotics. Fish generally lacked except for one harboring rsmA. Non-metric multidimensional scaling revealed distinct microbial communities water, compared with those samples, indicating potential cross-contamination during handling or storage. Our findings emphasize that containers could be critical points minimizing AMR spread. Overall, highlights interconnection between environmental, fish, human health, highlighting importance integrated surveillance management systems.

Is Deuterium Sequestering by Reactive Carbon Atoms an Important Mechanism to Reduce Deuterium Content in Biological Water?

FASEB BioAdvances, Год журнала: 2025, Номер unknown

Опубликована: Май 14, 2025

ABSTRACT Deuterium is a natural heavy isotope of hydrogen, having neutron as well proton. disrupts ATP synthesis in mitochondria, causing increased production reactive oxygen species and reduced ATP. Gut microbes likely play significant role providing deuterium depleted short chain fatty acids (SCFAs) to human colonocytes through hydrogen gas recycling. The (deupleted) nutrients necessarily leaves behind enriched water, unless there process that can sequester small molecules are excreted the feces. Here, we provide evidence number classes uniquely structured carbon‐nitrogen rings bis‐allylic carbon atoms certain biologically active may crucial sequestering for export into feces or urine. Specifically, have identified imidazole ring present histidine, histamine, microbial derivatives tetraterpenoid lutein, bilirubin urobilinogen stercobilinogen produced by gut microbes, carbons polyunsaturated candidates thereby reducing levels water‐based medium. Normally, never exchange their bound protons with deuterons from medium, but all above important exceptions this rule, has been shown experimentally.

Antimicrobial resistance is associated with increasing mortality rates and the emergence of multidrug-resistant (MDR) organisms. There scarcity data on short-term impact Stewardship Programs (ASP) antibiotic usage, clinical outcome MDR organisms' pattern following COVID-19 pandemic. This study evaluated effects ASP outcomes in post era. Conducted at a tertiary academic health center, this observational involved adult patients (≥18 years) general medical unit, treated oral or intravenous antibiotics from May 1, 2021, to April 30, 2022. The applied strategy was prospective audit feedback where weekly meeting held discuss antimicrobial therapy admitted patient, after which recommendations were made regarding use. included 301 166 (55.1%) pre-ASP 135 (44.9%) post-ASP. median (IQR) age 69 (55-77) years 56.1% female. Antibiotic usage dropped by 25.2% length hospital stay (LOS) longer post-ASP (7 days vs. 7.9 days, p = 0.001), infections being significant predictor (OR: 0.486, <0.001). no differences 28-day readmission, recurrence all-cause mortality. Post-ASP, pathogens increased (17.0% 6.6%, 0.013), However, separating into two three-months periods, MDROs numbers decreased slightly (13 10). Short-term implementation reduced while other remained unchanged. Nonetheless an increase LOS observed. Further research required assess ASP's long-term rates. specific patient group outcomes.
