Antibiotic Resistance
Antibiotic resistance (ABR) refers to the ability of bacteria to build up an immunity against antibiotics, creating significant global health issues and threatening modern medicine.
Antibiotic resistance creates serious global health issues, potentially causing a post-antibiotic era. This impacts human and animal health, causing longer, more aggressive illnesses, and detrimental effects on the environment.
What is Antibiotic Resistance?
Antibiotic resistance (ABR) occurs when bacteria, or microbials, that used to be mitigated by antibiotics are now able to withstand the effects of antibiotics. Microbes of the bacteria are not only able to live when treated with antibiotics, but can multiply, causing more stress to the host. When antibiotics are used to treat infections, the host can build up a tolerance if undertreated or mistreated.
Antibiotic resistance specifically refers to bacteria evolving to survive antibiotics designed to kill them. When bacteria survive exposure to an antibiotic, they can pass along their resistance mechanisms to other bacteria — creating "superbugs" that are increasingly difficult to treat with available medications.
Antibiotic resistance poses a serious global health threat as it can lead to the failure of antibiotic treatment, prolonged illnesses, increased healthcare costs, and higher mortality rates. It limits the options for effective treatment of infections and makes it more challenging to control the spread of diseases. Addressing ABR requires a comprehensive approach, including appropriate antibiotic use, improved infection prevention and control measures, the development of new antibiotics, and global collaboration to tackle this issue.
The Connection Between Antibiotics and Antimicrobial Resistance
Since their invention, germs have been evolving to build a tolerance against antimicrobial drugs. When the same antimicrobial is overused in humans or animals, the parasite, disease, or virus isn't as strongly affected or killed off due to this built-up tolerance. Over time, this results in antimicrobial resistance as germs are not effectively killed when combated with antimicrobials.

Antibiotic misuse and overuse are significant contributing factors to the development of antibiotic resistance. When antibiotics are used inappropriately, such as not completing the full course of treatment or using them for viral infections, it provides an opportunity for bacteria to survive and develop resistance. Antibiotic resistance happens in both humans and animals due to the following factors:
Overprescription & Inappropriate Use
Using antibiotics for viral infections where they have no effect creates unnecessary selection pressure on bacteria.
Agricultural Use
Antibiotics used as growth promoters in livestock accelerate resistance development across species.
Poor Infection Control
Inadequate hygiene and infection prevention practices in healthcare settings enable resistant strains to spread.
Lack of New Antibiotic Development
The antibiotic pipeline has stagnated — few new drugs are being developed to replace those losing effectiveness.
These are just some of the contributing factors to ABR. As new diseases form, economies shift, and the environment changes, there are additional issues that will take a global effort to mitigate.
The Mechanisms of Antibiotic Resistance
Bacteria employ several strategies to resist antibiotics. These include enzymatic degradation (breaking down the drug before it works), efflux pumps (actively pumping the antibiotic out of the cell), and target modification (changing the molecular target so the antibiotic can no longer bind to it).
Understanding these mechanisms is critical for developing both new antibiotics and diagnostic approaches that can detect resistance genes before treatment begins.
Intrinsic Resistance
The natural ability for an organism to withstand antibiotic effects based on their inherent cellular components and structural characteristics.
Acquired Resistance
The development of resistance to antibiotics over time due to changes or mutations of a bacteria — enabling previously susceptible strains to survive treatment.
Genetic Change
Bacteria acquiring new genetic material due to mutation or gene transfer between different bacteria through molecules and DNA, enabling resistance traits to emerge and persist.
DNA Transfer
Resistance genes spread through transformation (naked DNA incorporation), transduction (bacteriophage-mediated transfer), and conjugation (direct cell-to-cell contact).
Antibiotic Resistance and the Future of One Health
ABR is a quintessential One Health issue. Resistant bacteria don't respect species boundaries — they spread between humans, animals, and the environment. Antibiotics used in agriculture can drive resistance that eventually affects human health, making a cross-sectoral approach essential.
With the ability of bacteria to mutate and resist antibiotics, there are even bigger issues at hand. One Health, the concept of the interconnectedness of all humans, animals, and the environment, is greatly impacted by antibiotic resistance. Each pillar of One Health is affected — from zoonotic transmission in animal populations to environmental contamination of waterways and soil.
With the contamination of our waterways, agriculture, and the overall negative impact on our environment, antibiotic resistance affects us all at an ecological level, which in turn affects us on an environmental level, which inherently impacts our economies.
One Health efforts must be implemented on a global scale, which poses its own wicked problems. Aligning One Health efforts worldwide is very difficult due to differing economies, cultural ideals, and opposing governmental agendas. However, if antibiotic resistance isn't mitigated, then we will enter a post-antibiotic era, which will be catastrophic to the environment and, in turn, cause economic ruin.
Learn About One HealthHow Biomeme is Addressing the Threat of Antibiotic Resistance
Biomeme provides decentralized, real-time molecular testing to help clinicians make informed decisions at the point of care, ensuring antibiotics are only used when appropriate. Our host response diagnostics can rapidly differentiate between bacterial and viral infections — the most impactful intervention point for reducing unnecessary antibiotic prescriptions.
Biomeme advocates for the responsible use of antimicrobials and antibiotics as the first fundamental step that healthcare providers must take when prescribing medications to patients. Of course, this is easier said than done, especially for smaller economies with fewer resources. With our microcellular tests and technologies, we offer rapid results and insights into an infection, determining how to treat it faster, which helps reduce the inappropriate use of antibiotics.
Additionally, the mobility of our diagnostics gives communities the resources they need, even in impoverished or rural areas. This allows practitioners to treat illnesses on a more global scale, which supports One Health efforts and overall global health.
