Summary: Between 2010 and 2016, there was a significant decrease of over 90% in cephalosporin usage in the French pig production sector, while the resistance of commensal and pathogenic Escherichia coli isolates also tended to decrease. This illustrates the efficiency of a well-defined multi-professional strategy in reducing antibiotic usage and containing resistance.

Summary: This study assessed the epidemiology and antimicrobial resistance of Campylobacter jejuni in swine processing at a slaughterhouse in Eastern Spain. The results revealed high levels of multidrug-resistant C. jejuni swine batch contamination, indicating the need to include the swine sector in national control programs to reduce the bacterium and its resistance.

Summary: Antimicrobial resistance is a major threat to public health, and the use of antimicrobials in animal husbandry is a major concern. This study analyzed the resistome profiles in pig farms in Brazil and found various resistance genes at different levels. There were differences in resistome profiles between different farms.

Summary: The study detected 33 MCRPEC strains in Guangxi, with high resistance to multiple antimicrobials, including third and fourth generation cephalosporins and carbapenem. It was observed that some MCRPEC strains were extensively drug-resistant, highlighting the importance of long-term surveillance of mcr-1-positive E. coli in pigs.

Summary: The study found that Salmonella is prevalent in both market and slaughterhouse samples, with a higher prevalence in market samples. Multiple serovars and multidrug resistance were identified, with some samples carrying ESBL genes. ESBL-producing Salmonella isolates were more prevalent in market samples than in slaughterhouse samples, suggesting a potential for outbreaks across the food chain.

Summary: This paper examines the role of antibiotics in the Swedish and Italian production systems, highlighting the significant difference in antibiotic consumption levels between the two countries. Sweden is able to compensate for antibiotic treatments through precautionary health and biosecurity measures, while Italy exhibits a different pattern of antibiotic consumption.

Summary: Runoff from manured agricultural fields can transport antimicrobial resistance (AMR) contaminants, including genes and bacteria, to downstream ecosystems. This study quantified the ability of prairie strips to reduce the presence of antimicrobial resistance genes in manure-laden runoff and characterized the impact of manure on prairie soil microbiomes over time.

Summary: Antimicrobial resistance (AMR) has become a global concern in recent decades due to the excessive use of antibiotics. This has led to genetic modifications in bacteria and the spread of AMR to both pathogenic and commensal bacteria. The presence of antibiotic residues in water, soil, and food has also raised concerns about public health risks. As a potential alternative to traditional antibiotics, antimicrobial peptides (AMPs) have shown promise in animal diets. However, their widespread use is hindered by issues such as in-vivo effectiveness, stability, and high production costs.

Summary: The study found that antimicrobial use was significantly higher in intensive farms compared to organic/extensive farms, while multi-drug resistance in Campylobacter and Staphylococcus was lower in organic/extensive farms. Resistance in Campylobacter and Staphylococcus to most antimicrobials was significantly higher in intensive pig herds compared to organic/extensive ones.

Summary: Restrictions on antibiotic growth promoters have led to the use of alternative growth promoters, with dietary copper supplementation being widely used in pig production. This study investigated the impact of two different copper-based feed additives on the swine gut microbiome and antibiotic resistome. The results showed that adding copper to the feed did not significantly affect the bacterial community composition or resistome, suggesting that there was no co-selection of antibiotic resistance genes or mobile genetic elements. This study provides important insights into the use of copper as a growth promoter in pig production and its potential impact on antibiotic resistance.

Summary: Prudent antibiotic use in pigs is crucial for animal health and preventing resistance. An evaluation of Escherichia coli isolates from pigs with enteric disorders showed high levels of resistance to commonly administered antibiotics. Isolates carrying virulence genes exhibited different resistance patterns compared to those lacking these genes. Continuous surveillance and further research on the genetic variation between pathogenic and nonpathogenic E. coli are necessary.

Summary: Research reveals that the gut microbiome of piglets undergoes significant changes postweaning, with the weaning age having only a temporary effect on the microbiome. Within 7 days postweaning, the gut microbiome of pigs tends to stabilize, showcasing a predictable shift in microbial composition.

Summary: This study aimed to investigate the effect of quarantine strategy on reducing antimicrobials in beef cattle production. The results showed that quarantine strategy can effectively reduce antimicrobial use in male cattle without compromising their performance. However, the effectiveness of biosecurity measures in beef production is still poorly understood and further research is needed.

Summary: Monitoring antimicrobial use in finfish aquaculture is crucial, but there is currently no standardized indicator suitable for reporting antibiotic usage in this industry. The development of suitable indicators will require industry engagement to ensure credibility and value to stakeholders.
