Introduction
Antimicrobial resistance (AMR) is an escalating global concern, rendering many once-effective antimicrobials useless and threatening modern medicine’s foundations [1]. RNA-based therapies offer precision, programmability, and modularity—tailoring interventions directly to microbial genetic machinery [2, 3].
Main RNA-based modalities include
• Antisense Oligonucleotides (ASOs): Short synthetic single-stranded RNAs that bind complementary mRNA in bacteria to inhibit translation or induce RNase H–mediated degradation [15].
• RNA Interference (RNAi): Though classically applied to eukaryotes, siRNAs or crRNAs delivered via nanoparticles (also termed “nanoantibiotics”) can silence microbial resistance or virulence genes while the carrier materials physically damage microbial membranes— enhancing lethality [3, 4,5].
• CRISPR-Cas Systems: Adapted as antimicrobials, CRISPR-Cas tools can precisely target and cleave resistance genes in pathogens via conjugative plasmids or phages [6].
• Ribozymes / External Guide Sequences (EGSs): Engineered noncoding RNAs that harness RNase P or ribozyme activity to degrade specific bacterial mRNAs [16].
Key strengths
• Target specificity—can silence essential microbial or resistance genes while sparing beneficial microbiota.
• Rapid design and adaptability—once delivery systems are in place, targeting new genes requires sequence change alone.
• Synergy potential—combining gene silencing with antibiotics or physical antimicrobial actions increases efficacy.

Introduction
Antimicrobial resistance (AMR) constitutes a profound global health crisis, jeopardizing the efficacy of antibiotics and posing a severe threat to the foundation of modern medical practice. The rise of multidrug-resistant (MDR) pathogens, which exhibit resistance to multiple classes of antibiotics, has significantly escalated the global burden of infectious diseases, complicating treatment protocols and increasing morbidity and mortality rates. According to the World Health Organization (WHO), AMR could lead to 10 million deaths annually by 2050 if current trends continue, accompanied by economic losses projected to reach trillions of dollars due to prolonged hospitalizations, increased healthcare costs, and reduced productivity. The traditional antibiotic development pipeline has stagnated, hampered by scientific complexities, high financial costs, and stringent regulatory frameworks, resulting in a critical shortage of novel antimicrobial agents. This necessitates the exploration of innovative strategies to combat AMR and preserve the utility of existing antibiotics. Among these strategies, Crispr-Cas (Clustered Regularly Interspaced Short Palindromic Repeats and Crispr-associated proteins) systems have emerged as a groundbreaking gene-editing platform with transformative potential for addressing AMR. Initially identified as a bacterial adaptive immune mechanism, Crispr-Cas has been repurposed to enable precise targeting of genetic elements, offering novel therapeutic, diagnostic, and environmental solutions. This chapter provides a comprehensive analysis of Crispr-Cas systems in the context of AMR, exploring their molecular mechanisms, diverse applications, current limitations, and future prospects across clinical, agricultural, and environmental domains. By leveraging the precision and programmability of Crispr-Cas, researchers aim to develop targeted interventions that mitigate the spread of resistance while minimizing collateral damage to beneficial microbial communities.

Introduction
Antimicrobial resistance (AMR) has emerged as a critical global health threat, diminishing the effectiveness of antibiotics against bacterial infections. Conventional strategies to counter AMR—including antibiotic stewardship programs and the development of new drugs—are often slow, expensive, and labor intensive. However, artificial intelligence (AI) and machine learning (ML) present ground breaking alternatives to address this challenge. By leveraging advanced computational techniques, AI can significantly speed up the discovery of novel antibiotics, enabling researchers to identify promising drug candidates more efficiently than traditional methods. Additionally, ML algorithms enhance treatment optimization by analyzing patient data to recommend personalized antibiotic regimens, reducing misuse and resistance risks. AI also strengthens surveillance systems by processing vast datasets— such as genomic sequences and electronic health records—to detect emerging resistance patterns in real time. These capabilities allow for proactive interventions, helping healthcare providers and policymakers stay ahead of AMR outbreaks. Together, AI and ML offer a transformative approach to mitigating AMR, combining speed, precision, and scalability to combat one of the most pressing medical challenges of our time.
AI in Antibiotic Discovery
One of the most promising applications of AI in AMR mitigation is in antibiotic discovery. Traditional drug development is costly and time-consuming, often taking over a decade [1]. Machine learning models can analyse vast datasets of chemical compounds to predict their antibacterial properties. For example, researchers at MIT used deep learning to identify halicin, a novel antibiotic effective against drug-resistant bacteria. AI-driven platforms can also repurpose existing drugs, reducing the time needed for clinical trials [2].

Predictive Analytics for Resistance Patterns AI-powered predictive analytics enables early detection of antimicrobial resistance (AMR) patterns by processing clinical, genomic, and epidemiological data. Machine learning models analyse electronic health records (EHRs) [3] and bacterial genome sequences to identify emerging resistance threats in real time. These predictive insights allow hospitals to take proactive measures— such as optimizing antibiotic prescriptions—before resistant strains spread. Beyond clinical settings [4], AI models assist public health agencies in forecasting outbreaks and strategically deploying resources. By integrating large-scale datasets, these systems enhance surveillance, enabling faster, datadriven decisions to curb AMR progression. This approach not only improves patient outcomes but also supports global efforts in combating antibiotic resistance through smarter, pre-emptive interventions [5].

Introduction
The safety of meat and its derivatives is a paramount concern in the dynamic realm of food trade. Consumers demand food products that are not only affordable and possess an extended shelf life but are also of high safety standards. Consequently, meat inspections require strict adherence to good manufacturing practices and safety labelling that aligns with regulatory standards. Food-borne pathogens, including Listeria monocytogenes, Staphylococcus aureus, pathogenic Escherichia coli, Clostridium perfringens, Campylobacter spp., and Vibrio spp., are responsible for numerous illnesses, thereby exerting a significant impact on public health and the economy. According to the World Health Organization (WHO), food contaminated with pathogens, chemicals, and allergens results in 600 million cases of food-borne illnesses and approximately 400,000 deaths globally each year. Furthermore, 56 million individuals die annually, with about 7.7% of the global population affected by foodborne diseases. Meat and meat products are essential sources of nutrients for humans, providing high-quality protein, essential amino acids, B vitamins, and minerals. However, due to their high-water activity and nutrient content, they also create a conducive environment for spoilage microorganisms and food-borne pathogens. Until a few decades ago, the meat industry was largely dominated by the unorganized sector, with limited access to knowledge that could enhance productivity. However, in the post-World Trade Organization (WTO) era, meat entrepreneurs have succeeded in increasing productivity, although they have faced challenges in ensuring product quality that aligns with the legislative standards of numerous developed and developing countries. The use of antibiotics as antimicrobial growth promoters in animal food production has been a contentious issue, as their unauthorized application has inadvertently contributed to the emergence of antibiotic-resistant bacteria within the food chain. Recently, the United States Trade Representative’s office estimated that international trade has expanded significantly since the General Agreement on Tariffs and Trade (GATT) was signed in 1947. The establishment of the WTO in 1995 further facilitated trade in animal-origin foods and live animals between nations. However, the emergence and re-emergence of diseases caused by pathogenic bacteria have become a significant concern in this new pattern of food trade. Some of these pathogens are so virulent that they were not previously reported. According to a 1998 report by the Centers for Disease Control and Prevention (CDC), the annual cost of foodborne illnesses in the United States is nearly 10 billion US dollars. The bacterial pathogens most commonly associated with illnesses from beef products include Salmonella spp., Clostridium perfringens, and Staphylococcus aureus. Interest in Escherichia coli O157: H7 increased following a highly publicized food poisoning outbreak linked to undercooked beef patties in the United States in 1993, although it was largely confined to North America until the mid-1990s. Similarly, multidrug-resistant Salmonella typhimurium DT-104 has spread widely since it was first identified in the United Kingdom. In India, the incidence of Salmonella in red meat was recorded at up to 9%. These potentially harmful bacterial pathogens can reside on the hides or in the intestinal tracts of foodproducing animals or may originate indirectly through cross-contamination or the processing environment. Other emerging foodborne diseases include Listeriosis, which has spread throughout France and Canada, where meat and meat products have been implicated as sources of Listeria monocytogenes. Similarly, Staphylococcal food poisoning or food intoxication syndrome, first reported in 1894, has become a global issue in the meat industry.

Our animal companions are our family members. We want the best for them and want them to be healthy and happy. However, just as it is with everyone else, our companion animals can also fall ill and suffer from emotions such as grief, fear, and anxiety. And while we follow all expert medical advice, sometimes we may wish for something more – something that will make life easier for them as well as us. This is where the concept of energy healing for animals comes in – to comfort and support our animal companions. With joy, we watch them relax with a sigh; we see our nervous dogs calm down, and those recovering from an acute illness get back on their paws in no time. Energy healing for animals involves a holistic approach to ensure the physical, emotional, and spiritual well-being of our animal friends. It is based on the fundamental concept that just like us, our animal companions too have a subtle energy layer, and they too have vital life-force energies or Prana or Qi. And just like us, they, too, have chakras and meridians through which the Qi flows. Energy healing is a set of powerful techniques practiced to calm and restore the balance of the body. This system is largely based on the removal of energetic blocks and helps restore the body’s energy levels. It is crucial for those living with companion animals to understand the importance of energy healing for their animal companions, as it encompasses a broad range of alternative and complementary therapies designed to support the natural healing process of animals. Here are some proven, popular, non-invasive energy healing techniques that bring relief and comfort to companion animals.
1. Animal Reiki: The word Reiki means “mystical energy.” The system of Reiki for healing was revealed by Japanese Buddhist practitioner Mikao Usui in the early 1900s. And while it was initially meant for humans, practitioners soon discovered that animals responded much more swiftly and effectively to this gentle, non-invasive energy work.
2. EFT Tapping: This involves tapping on specific points on the body to free up emotional blocks. EFT Tapping for animals brings powerful transformations when an animal is struggling with emotional distress, such as grief over the loss of a loved human or animal.
3. Scalar Wave Healing: Scalar Wave was discovered in the 1900s by James Maxwell and later Nicolas Tesla. Scalar Wave harnesses the healing power of high vibrational frequencies meeting to create a standing wave, and practitioners use this to bring about healing at a cellular level.
4. Shamanic Healing: In this ancient technique, practitioners work with the elements of nature, such as plants, trees, and stones, as well as beings in other dimensions, to bring about healing. Shamanic healing can reach beyond space and time and has been very effective in releasing old trauma or emotions that are often hidden beneath layers of survival mechanisms.
5. Healing Mantra: Ayurveda, the Indian system of medicine, advocates about different types of Chikitsa. Daivavyapashraya Chikitsa is one of the treatment approaches concerned with Spiritual way of treatment. It includes so many approaches, amongst all Mantra Chikitsa is described in Ayurveda at various places as a potent approach. It is discussed for both the healthy and unhealthy conditions. Mantra comes from Sanskrit word which means sacred message or text, spell. The word Mantra is derived from Man+Tra, man—mananaat---just by chanting and tra—trayate---- we can protect ourselves. Means, just by chanting one can save himself in the universe. i.e. it is saved from onset of disturbances. Mantras are the words loaded with power and sounds capable of penetrating our body into deep levels. Mantra chikitsa is the ancient science originated from Vedas, this is a parallel science to Ayurveda also called alternative medicine system.Mantra Chikitsa is one among the Daivavyapashraya Chikitsa highlights the importance of concept of Mantra. In Atharva Veda and Kaushikasutra, the two most ancient and authentic sources of Daivavyapashraya. Mantra Chikitsa is mainly used for both preventive and curative aspect. It is also used for the enhancement of the Gunas of Aushadhi. Effect of Mantra is described as Prabhavajanya action. Prabhava means the specific and characteristic action of substances, it is called as Acintya. Mantra Chikitsa cure the Karmaja Vyadhi and Agantuja Vyadhi. In the Vedic period, Daivavyapashraya Chikitsa was followed in various rituals.

Introduction
It is reasonable to consider that the history of humanity has been marked by two transformational revolutions: the cognitive revolution (35,000 to 70,000 years ago), when Homo sapiens began to manifest our capacity to abstract, imagine things that did not exist and give meaning to non-representational thoughts; the agricultural revolution (10,000 to 12,000 years ago), when Homo sapiens stopped being a hunter/collector to settle on land, cultivating the soil and raising domesticated animals. It was possibly the beginning of property ownership, monogamy, family and also when malaria, and other diseases more easily spread in communities, became consolidated as human diseases. It was with the cognitive revolution that things changed and our previously acquired abilities of creating images and dealing with abstract concepts started to push humankind to become the “Dominant Mammal” controlling all other animals and Earth’s environments. Progressively, man learned to work with wood, iron and all minerals extracted from the soil, produced clothes with leather and wool from animals, linen and cotton from plants, silk from insects, and latter from natural oils created arts, jewellery, dynamite, electricity, vaccines, transatlantic ships, locomotives, cars, computers, antibiotics, contraceptives, robots, portable cell phones, informatics, bioengineering, internet, artificial intelligence, social networks and many other innovations . Not surprisingly, conscious of all these attributes, man felt important, central and essential, falling into the temptation of judging himself a magnificent creature with all rights and that became deep rooted in some cultures. For the pleasure,comfort, sophistication and power, man interfered with and altered the environment in a so ambitious and predatory manner that he modified and compromised his and other species living conditions, causing also climate changes that threaten his own survival on the planet. With time, it became clear that, in addition to this entirely anthropocentric “Ego’s” point of view, there might be another perspective fromwhich one can perceive the world and interact with it. An ecological “Eco’s” perspective corresponds to a compassionate view (how can we contribute to the greater good and make the world a better place) of the Globe. After all the damage done to nature by man, moving from the socalled Ego to the Eco attitude became a mandatory needConcerning Global Health, for a long-time, human health has benefited by sacrificing the “health” of wild ecosystems (e.g., deforestation and conversion of wilderness to farmland, damming of water for irrigation, destruction of swamps and dislocation and jeopardy of wild species) which reflects a protectionist vs utilitarian conflict, over the question of whether to put human domination of the biosphere on hold or whether to embrace it .It hides unaddressed concerns about the value of (macroscopic) life (human, animal or plant), the definitions of health and wellbeing (human, animal, plant and environmental) and their relative importance. This has hampered the development and acceptance of a One Health (OH) understanding of Global Health.

Introduction
Antimicrobial resistance (AMR) is increasingly recognised as a “silent pandemic,” threatening global health and development. In 2019 alone, bacterial AMR was directly responsible for 1.27 million deaths and contributed to nearly 5 million more worldwide. Projections warn that by 2050, unchecked AMR could result in 10 million annual deaths and impose a staggering economic burden of USD 100 trillion. A major driver of this crisis is the indiscriminate and often prophylactic use of antibiotics in livestock production systems, which account for a majority of global antimicrobial consumption. The One Health framework—emphasising the interconnectedness of animal, human, and environmental health—offers a strategic pathway for mitigating AMR. It requires dismantling sectoral silos and fostering collaboration among veterinarians, physicians, public health authorities, food safety regulators, and environmental scientists. Against this backdrop, NDDB has positioned itself as a frontrunner in India by embedding One Health principles into large-scale field programmes. Since 2014, NDDB has progressively promoted alternative medicine for bovine mastitis control under its Mastitis Conrol Project (MCP), subsequently expanding in 2017–18 into a broader Disease Control through Alternate Methods (DCAM) project with Ethnoveterinary Medicine (EVM) as the central pillar.
Building Up: From DCAM to DISHA as One Health Strategy
Building on the successes of MCP, DCAM, and BCP, NDDB launched the Dairy Integrated Safety and Health Action (DISHA) project for 2025–2030, DISHA consolidates NDDB’s One Health strategy by combining animal health management, zoonotic disease surveillance, and food safety monitoring. Its objectives include: managing bovine cases with EVM, organising farmer awareness programmes, training veterinarians and health workers, screening cattle as well as their owner for brucellosis, and testing bulk milk samples for aflatoxins and antibiotic residues. Importantly, DISHA also addresses emerging food system contaminants such as microplastics, per- and polyfluoroalkyl substances (PFAs), Bisphenol-A (BPA) and heavy metals, thereby broadening the scope of One Health beyond infectious diseases.

Introduction
AMR is a critical global problem that affects human, environmental, and animal health. AMR is a complex problem; it is necessary to look at it from different disciplines to frame it within the One Health approach [Shrestha,2018].The World Health Organization (WHO) has identified AMR as a top ten global public health threat.Globally, there were an estimated 4.95 million deaths associated with bacterial AMR in 2019, including 1.27 million deaths attributable to bacterial AMR [O’Neill, J. (2016)]. The economic impact is equally alarming. The World Bank projects that AMR could lead to an additional US$ 1 trillion in healthcare costs by 2050, and over US$ 1 trillion in annual gross domestic product (GDP) losses by 2030.The One Health approach is defined as a joint effort of various disciplines that come together to provide solutions for human, animal, and environmental health. AMR is linked to each of these three components due to the irresponsible and excessive use of antimicrobials in various sectors (agriculture, cattle raising, and human medicine). Under the pressure of antimicrobial selection, bacteria acquire resistance genes and mobile genetic elements that can spread to other bacteria of the same or different genus. When bacteria acquire resistance to antimicrobials, they also acquire a greater ability to proliferate in animals, humans, and the natural world. Mismanagement of antimicrobials, inadequate infection control, agricultural debris, contaminants in the environment, and migration of people and animals infected with resistant bacteria facilitate the spread of resistance [Collignon,et.,al,2018]. AMR represents a global public health problem, for which epidemiological surveillance systems have been established, aiming to promote collaborations directed at the well-being of human and ani mal health and the balance of the ecosystem. Several international organizations (The World Organisation for Animal Health [OIE], WHO, and the Food and Agriculture Organization of the United Nations [FAO]) have joined forces to develop a Global Action Plan on Antimicrobial Resistance-WHO. Action taken in this plan included understanding the AMR from surveillance and research. The advisory group established guidelines for AMR surveillance to ensure all countries implement integrated surveillance, which will cover the use and consumption of antimicrobials in the human and animal population. These guide lines will provide a clear understanding of how AMR spreads in different settings and specific areas. It will allow to study the correlation between AMR and antimicrobial use in a different setting (animals, humans, and environment) and to assess the effect of interventions within and between sectors [W.H.O 2015,2017].

Introduction
Antimicrobial resistance (AMR) has emerged as one of the most pressing global health threats, with implications that extend beyond human medicine to animal health, food security, and the environment. In livestock production systems, the misuse and overuse of antibiotics contribute significantly to the development of resistant pathogens. These resistant organisms can spread from animals to humans through direct contact, contaminated food products, and environmental pathways. The containment of AMR in livestock is not solely a technical or regulatory challenge—it is also a social and behavioral issue. Public awareness, education, and behavioural change are key pillars of any effective AMR mitigation strategy. Schools, community networks, and media platforms play vital roles in shaping knowledge, attitudes, and practices related to antibiotic use in livestock.
Causes of AMR in Livestock
Over-prescription and misuse of antibiotics in veterinary care Use of antimicrobials as growth promoters rather than for therapeutic purposes Poor farm bio-security and hygiene leading to frequent infections
Inadequate regulation and over-the-counter sale of antibiotics without veterinary oversight
Public Health Impact
Transmission of resistant pathogens via the food chain Contamination of soil and water with resistant genes through manure
Emergence of zoonotic diseases with limited treatment options

Introduction
Animal sector is growing very fast particularly in India as people’s purchasing power is increasing day by day. With increase in income, people’s dietary habit is shifting towards more animal origin products. The use of antibiotics for animal food production is growing very fast and India is the 4th largest country in the world regarding consumption of antibiotics in veterinary and animal husbandry sector. There is urgent need of AMR mitigation strategies to reduce the effect on human and animal health. As per the World Bank AMR can affect the global GDP upto 3.8% by 2050. Most of the countries in the world are very cautious regarding antibiotic residues and rejecting the livestock products which lead to economic loss. Many world agencies/forum such as CodexAMR Guidelines, UN Political Declaration on AMR Guidelines, Global Leaders Group on AMR reiterated judicious use of antibiotics. All-India Network Project on AMR inLivestock and Fisherieswas started in India to reduce the effect of AMR by educational awareness, adoption at field level, surveillance system and diagnosis but it didn’t meet out the desired outcome. Capacity building programmes in the field of AMR by training, reform in curriculum, collaboration from different fields of professionals can mitigate the harmful effect of AMR. According to the Food and Agriculture Organization (FAO), education and training play pivotal roles in translating knowledge into practical implementation, warranting the inclusion of Antimicrobial Use and AMR as integral components in professional education, postgraduate training, and continuing education within the food and agricultural sectors Training Strategies It involve Antimicrobial Stewardship training for healthcare professionals, public awareness campaigns, farmer education, and veterinary training on responsible antimicrobial use. Other critical elements include fostering collaboration through professional networks, building surveillance capacity, utilizing AI-driven tools for better decision-making, and promoting hygiene and infection prevention to reduce infection incidence and the need for antibiotics.
Training for Healthcare Professionals
There is substantial evidence that both healthcare workers and members of the public have knowledge gaps about appropriate use of antibiotics and mechanisms of antibiotic resistance. Surveillance is a prerequisite to estimate the magnitude of the AMR burden and to establish any intervention strategies, such as antimicrobial stewardship. In order to launch successful intervention approaches through cooperative efforts from different stakeholders (e.g., international agencies, human and veterinary medicine sectors, agriculture and animal production industries, and consumers), the existing knowledge gap needs to be addressed first.

Introduction
Antimicrobial resistance (AMR) has emerged as one of the most alarming public health challenges of the 21st century, threatening the effectiveness of life-saving drugs and the future of modern medicine. This crisis is not limited to healthcare settings; it spans communities, agriculture, and the environment, impacting every facet of society. India, with its large population, high burden of infectious diseases, unregulated access to antibiotics, and considerable pharmaceutical manufacturing industry, stands at the forefront of the global struggle against AMR. The rise of resistant microbes stems from a complex interplay of factors: overuse and misuse of antibiotics in humans and animals, poor infection prevention practices, lack of sanitation, and environmental contamination from antibiotic waste. As a result, common infections are becoming harder to treat, surgical procedures riskier, and healthcare costs are escalating, all leading to increased morbidity and mortality. Tackling AMR requires robust intersectoral collaboration—no single stakeholder can succeed alone. Non-governmental organizations (NGOs), industries, and Corporate Social Responsibility (CSR) initiatives form a critical triad in India’s fight against AMR. NGOs drive grassroots education, advocacy, surveillance, and policy change, often bridging gaps where governmental capacity is limited. The pharmaceutical and healthcare industries, responsible for antibiotic manufacturing, distribution, stewardship, and infection control, play a pivotal role in curbing environmental emissions, supporting responsible use, and promoting the discovery of new treatments. Meanwhile, CSR channels the resources and expertise of corporations towards sustainable, communityfacing projects that promote awareness, improve hygiene, foster stewardship, and drive systemic change.
