The position paper of the European Association of Hospital Pharmacists (EAHP) highlights the importance of the prudent use of antimicrobial drugs through antibiotic stewardship to ensure efficient therapy for patients with life-threatening infections. EAHP calls on national governments and health system managers to utilise the specialised background and knowledge of the hospital pharmacist in multi-professional antibiotic stewardship teams. In addition, the paper recommends the universal application of infection prevention and control measures among healthcare professionals. Due to the lack of funding, EAHP urges increased investment to support the development of innovative proposals and the encouragement of practice-based research projects to investigate new fields of infectious disease control such as immunotherapy and to optimise the cost-effectiveness of systems for surveillance on antibiotic use and resistance. In relation to the 'One Health approach' of the European Commission, EAHP strongly supports regulatory oversight and proper implementation of measures in the veterinary and agriculture sectors at European, national and local level.

Introduction: Antimicrobial Stewardship Program (ASP) aims to reeducate the use of antimicrobials. Objective: To manage and evaluate the implementation of ASP in an Adult Intensive Care Unit in Brazilian hospitals. Method: Prospective cross-sectional study, reporting introductory data and factors that advised and helped to implement the ASP in 954 (55.6%) hospitals, corresponding to 25,565 beds, from all 27 Brazilian states.Results: Of the 954 hospitals, 453 (47.5%) have ASP, with the most regular factors being: 369 (81.5%) top management support; 343 (75.7%) availability of clinical protocols; 276 (60.9%) support and adherence by doctors and 259 (57.2%) official definition of the management team. The most difficult causes were: 202 (44.6%) operational team without defined or insufficient time; 134 (29.6%) lack of information technology support; 173 (38.2%) resistance or opposition from doctors and 116 (25.6%) lack of commitment from the teams. Conclusion: the implementation of ASP is an executable proposal for the optimization and rational use in the management of antimicrobials. In Brazil, this proposal will collaborate for direct actions in ICUs, guided by the government, with a relevant impact on the control of antimicrobial resistance. In Brazil, this proposal will contribute to direct actions in ICUs, guided by the government, with a relevant impact on the control of antimicrobial resistance.

Antimicrobial-resistant infections are becoming more frequent and increasingly difficult to treat, and this situation is exacerbated by the widespread use of antimicrobials in both human and veterinary medicine and by the agriculture industry. As part of Canada's coordinated response to addressing antimicrobial resistance (AMR), Tackling Antimicrobial Resistance and Antimicrobial Use: A Pan-Canadian Framework for Action, was released in September 2017. The Framework is a high-level policy document that outlines the strategic objectives, outcomes and opportunities to guide collaborative action on AMR and antimicrobial use (AMU). It is grounded in a One Health approach, and was developed in collaboration with federal, provincial and territorial governments and external stakeholders in the human and animal health sectors. The Framework is based on four components: surveillance; infection prevention and control; stewardship; and research and innovation. It builds upon existing AMR activities already underway in the human and animal health sectors and strives to connect these activities together to strengthen Canada's approach to AMR.

Bacteria develop resistance to antibiotics following low-level "background" exposure to antimicrobial agents as well as from exposure at therapeutic levels during treatment for bacterial infections. In this review, we look specifically at antimicrobial resistance (AMR) in the equine reproductive tract and its possible origin, focusing particularly on antibiotics in semen extenders used in preparing semen doses for artificial insemination. Our review of the literature indicated that AMR in the equine uterus and vagina were reported worldwide in the last 20 years, in locations as diverse as Europe, India, and the United States. Bacteria colonizing the mucosa of the reproductive tract are transferred to semen during collection; further contamination of the semen may occur during processing, despite strict attention to hygiene at critical control points. These bacteria compete with spermatozoa for nutrients in the semen extender, producing metabolic byproducts and toxins that have a detrimental effect on sperm quality. Potential pathogens such as Klebsiella pneumoniae, Escherichia coli, and Pseudomonas aeruginosa may occasionally cause fertility issues in inseminated mares. Antibiotics are added during semen processing, according to legislation, to impede the growth of these microorganisms but may have a detrimental effect on sperm quality, depending on the antimicrobial agent and concentration used. However, this addition of antibiotics is counter to current recommendations on the prudent use of antibiotics, which recommend that antibiotics should be used only for therapeutic purposes and after establishing bacterial sensitivity. There is some evidence of resistance among bacteria found in semen samples. Potential alternatives to the addition of antibiotics are considered, especially physical removal separation of spermatozoa from bacteria. Suggestions for further research with colloid centrifugation are provided.

Simple SummaryBacteria can develop resistance to antibiotics, resulting in the appearance of infections that are difficult or impossible to treat. This ability enables bacteria to survive in hostile environments and can result from exposure to even small amounts of antibiotic substances. Bacteria are present in the reproductive tract of the horse; they can develop resistance to antibiotics, because the animal has been treated for an infection, or due to insemination with a semen dose that contains antibiotics. Bacteria colonize the membrane lining the male reproductive tract and are transferred to the semen during collection. They can cause sperm quality to deteriorate during storage or may cause an infection in the mare. Therefore, antibiotics are added to the semen dose, according to legislation. However, these antibiotics may contribute to the development of resistance. Current recommendations are that antibiotics should only be used to treat bacterial infections and where the sensitivity of the bacterium to the antibiotic has first been established. Therefore, adding antibiotics to semen extenders does not fit these recommendations. In this review, we examine the effects of bacteria in semen and in the inseminated mare, and possible alternatives to their use.Bacteria develop resistance to antibiotics following low-level "background " exposure to antimicrobial agents as well as from exposure at therapeutic levels during treatment for bacterial infections.

The frequent use of antimicrobials in pediatric patients has led to a significant increase in multidrug-resistant bacterial infections among children. Antimicrobial stewardship programs have been created in many hospitals in an effort to curtail and optimize the use of antibiotics. Pediatric-focused programs are necessary because of the differences in antimicrobial need and use among this patient population, unique considerations and dosing, vulnerability for resistance due to a lifetime of antibiotic exposure, and the increased risk of adverse events. This paper serves as a position statement of the Pediatric Pharmacy Advocacy Group (PPAG) who supports the implementation of antimicrobial stewardship programs for all pediatric patients. PPAG also believes that a pediatric pharmacy specialist should be included as part of that program and that services be covered by managed care organizations and government insurance entities. PPAG also recommends that states create legislation similar to that in existence in California and Missouri and that a federal Task Force for Combating Antibiotic-Resistant Bacteria be permanently established. PPAG also supports post-doctoral pharmacy training programs in antibiotic stewardship.

Antimicrobial resistance (AMR) is the phenomenon developed by microorganism on exposure to antimicrobial agents, making them unresponsive. Development of microbial confrontation is a severe rising risk to global community well-being as treatment in addition, management of such resistant microbial infections is difficult and challenging. The situation requires action across all government sectors and society. The change in the molecular target on which antimicrobial drugs act is one of the key mechanisms behind AMR. One of the approaches to battle with AMR can be exploring newer molecular targets in microbes and discovering new molecules accordingly. There are various examples of novel targets such as biomolecules involving in biosynthesis of cell wall, biosynthesis of aromatic amino acid, cell disunion, biosynthesis of fatty acid, and isoprenoid biosynthesis and tRNA synthetases. Fatty acid biosynthesis (FAB) and their enzymes among all the above is the more appealing target for the advancement of new antimicrobial agents. Number of promising inhibitors have been developed for bacterial fatty acid synthesis (FAS) and also few of them are clinically used. Some of these potential inhibitors are found to be used in development of new antibacterial as a lead compound and have been discovered from high throughput screening processes like Platencimycin and their analogue, Platencin. The review majorly encompasses bacterial FAB in type II FAS system and potential inhibitors with respective targets of novel antibacterial.

"This book explores the role that environmental distribution of antimicrobial resistance genes and antibiotics plays in ecosystem and human health. The text features a multi-disciplinary framework that connects microbiology, environmental toxicology, and chemistry to assess human and ecological risk associated with exposure to antibiotics or antibiotic resistance genes as environmental contaminants. It also considers alternate uses and functions for antimicrobial compounds other than those intended for medicinal purposes in humans, animals, and fish. Recognizing the connectivity between overlapping complex systems, the book discusses the subject from the perspective of an ecosystem approach"--
