This document discusses the future impacts of antibiotic resistance if it is not addressed. It notes that antibiotic resistance could lead to 10 million deaths per year by 2050 and cost the global economy billions. The world may enter a post-antibiotic era where common infections become difficult to treat again. Many drugs will become ineffective as resistance spreads, and new resistance mechanisms may emerge. Medical procedures could become more dangerous without effective antibiotics to treat associated infections. The costs of antibiotic resistance will be high both in terms of health and economic impacts. Urgent changes are needed in antibiotic use and development to address this growing threat.
The use of antimicrobial in humans and animals, the consequences of this use, the political and economic barriers to improve prudent use and possible solutions for this problem.

Literature Survey Antibiotic ResistanceTuhin Samanta
Anti-toxin obstruction happens when microscopic organisms change in light of the utilization of these medications. Microscopic organisms, not people or creatures, become anti-toxin safe. These microorganisms may contaminate people and creatures, and the diseases they cause are more diligently to treat than those brought about by non-safe microscopic organisms.

On 12/2/09 on Capitol Hill, leading experts in economics, public health and public policy and Rep. Louise Slaughter (D-NY), a leading voice on antibiotic resistance, discussed the impact of resistant infections on the U.S. healthcare system and the need to phase out inappropriate use of antibiotics as growth promoters in the production of food animals. The Johns Hopkins Center for a Livable Future (CLF) hosted the event with Rep. Slaughter. This is a complication of the panelists' presentations.
Antibiotic resistance: causes, consequences and means to limit itGreenFacts

Awareness Session On Antimicrobial resistance “Antimicrobials: Spread Awaren...Nimra zaman
The World Antimicrobial Awareness Week (WAAW) was introduced by the World Health Organization (WHO) to increase global awareness of antimicrobial resistance.
The WAAW takes place every year from 18-24th of November.
The theme of World Antimicrobial Awareness Week (WAAW) 2021 is ‘Spread Awareness, Stop Resistance’.
During this week best practices are shared among the general public, health workers and policy makers to show the importance of stopping the further emergence and spread of antibiotic resistance.
Emergence of Drug resistant microbes PPT By DR.C.P.PrinceDR.PRINCE C P
Antimicrobial resistance is resistance of a microorganism to an antimicrobial drug that was originally effective for treatment of infections caused by it.
Resistant microorganisms (including bacteria, fungi, viruses and parasites) are able to withstand attack by antimicrobial drugs, such as antibacterial drugs (e.g. antibiotics), antifungals, antivirals, and antimalarials, so that standard treatments become ineffective and infections persist, increasing the risk of spread to others.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

2. Why does this matter?
Antibiotic resistance does not only influence health in
the global population at present, but has the potential
to cause devastating worldwide consequences in the
future
Recognition of these possible future impacts helps to
emphasise the need for drastic change in the
prescription and usage of antibiotics
5. Post-antibiotic era
It is estimated that if antibiotic resistance is not tackled,
10 million people could die per year of curable
diseases by 20501
The economy could lose billions of dollars more per
year due to increased loss of public health goods as
well as the huge costs associated with dealing with this
issue
The world may enter a post-antibiotic era, whereby
previously treatable infections and injuries can become
deadly once more2
7. Treatment failures
Many drugs, after development, had negligible or very
low failure rates and generally succeeded in curing
various life-threatening diseases2
With the emergence of antibiotic resistance, patients
worldwide have failed to respond to previously effective
antibiotic treatments2
This includes the emergence of multidrug-resistant
tuberculosis, Plasmodium falciparum, methicillin-
resistant Staphylococcus aureus (MRSA) and so on3
Drugs such as fluoroquinolones, carbapanems,
cephalosporins and so on are now ineffective in more
than half of people in countries all around the world2,3
8. There has also been rapidly increasing resistance to drugs
used to treat tuberculosis, malaria, influenza, gonorrhea,
urinary tract infections and so on2
With the rapid spread of antibiotic resistance, these
diseases will soon become extremely difficult to manage and
can cause increased disability and death2,3
In terms of morbidity and mortality, diseases are expected to
vary across countries
Malaria is expected to be the most significant in Asian
countries, while tuberculosis is expected to severely impact
Russia1
9. MRSA
This is predicted to become a huge public health issue
The scope of this resistance will extend to more settings –
hospitals used to be the only settings where MRSA was
found, but more community outbreaks can be expected4
These outbreaks may happen in people who lack traditional
risk factors for MRSA4
MRSA prevalence in the US community may reach 25% in
the next 10 years, with even higher rates within hospital
settings4
10. Loss of control over infection
If antibiotic resistance continues, global health systems
will lose control over many infectious diseases
The rates of hospitalisation and infection will be
elevated, and alternative treatments will need to be
sought
Longer hospitalisation periods and greater extent of
disability3
Death rates from infectious diseases will inevitably
increase
11. Resistance mechanisms
There is the potential for new resistance mechanisms to
emerge, and for resistance rates as a whole to increase4
Multiresistant streptococci, staphylococci and enterococci
will potentially cause substantial illness and be difficult to
combat, especially in parts of the world that have not yet
implemented strict control measures4
Vancomycin-resistant antibiotics may become endemic on a
global scale4
A huge number and range of antibiotics will be rendered
useless in the treatment of a large number of diseases
12. Development of antibiotics
There have been no new antimicrobial classes developed for
gram-negative bacteria for decades4
Vaccines have not been widely effective4
Fluoroquinolones used to be widely effective against multiple
infections, but this is not the case anymore. There have also not
been any new class of antimicrobial agents to function as a
substitute for them4
Several new antimicrobial drugs with different mechanisms of
action have failed in phase three trials4
Antibiotics are being rendered useless very quickly but no novel
antibiotics have been found to be successful – this is very
concerning and can have devastating implications for the health of
global populations
13. Medical procedures
Antibiotics have commonly been used to treat infections that
appear secondary to procedures such as caesarean child
birth, organ transplants, chemotherapy and so on1,2
With the growing resistance against antibiotics, these
procedures will be able to cause diseases which may soon
be rendered incurable1
Therefore, these procedures can become much more
dangerous, and are expected to cause higher rates of
persistent infection and death1
This will impact not only wealthier countries where such
procedures are common, but also middle income countries
that are trying to implement health systems1
14. Costs of antibiotic resistance
There will be a significant loss of public health goods due to
antibiotics being rendered useless by growing resistance, and
substantial economic losses
Patients infected with drug-resistant bacteria generally suffer from
longer-lasting and more severe infections, and as such require
extended hospitalisation and increased treatment and care
resources 2,4,5
Broad-spectrum antibiotics are being used increasingly for
empirical therapy of many common infections – these agents are
often costlier, and have more toxicity towards protective microflora.
They are also occasionally less effective5
Alternative therapies and treatments are required, and these can
be expensive to develop or implement
15. Therefore, it can be seen that antibiotic resistance is a
pressing issue that can have severe, negative
consequences on numerous countries worldwide.
It is essential to understand these impacts in order to
grasp the importance of changing attitudes towards
antibiotic development, prescription and usage.
