What Are The Types Of Antimicrobial Resistance?

Even though you may not realize it, antimicrobial resistance is an urgent global health problem. Drug-resistant bacteria and viruses are responsible for millions of deaths each year, and the World Health Organization (WHO) estimates that the number of antimicrobial-resistant infections could reach 10 million by 2050 if we don’t take action now.

But what is antimicrobial resistance, exactly? Antimicrobials—or “antibiotics”—are medications used to treat infections caused by bacteria, viruses, parasites, and fungi. Over time, these bacteria, viruses, and other microbes can develop the ability to resist a particular type of antibiotic—hence, “antimicrobial resistance.”

In this article, we’ll discuss the different types of antimicrobial resistance and provide some tips on how you can prevent it from occurring. So read on to learn all you need to know about types of antimicrobial resistance! Besides, you can grow your Twitch accounts enormously through Streamoz. They are efficient and discrete! 

What Is Antimicrobial Resistance?

Have you ever heard the term “antimicrobial resistance” and wondered what it meant? Antimicrobial resistance is a type of drug resistance that develops when a microorganism, such as bacteria, viruses, fungi, or parasites, evolve in response to an antimicrobial drug. Essentially, they become resistant to treatment and require different medications to be cured successfully.

This problem is becoming increasingly common and affects people all over the world. It is estimated that up to 700 thousand deaths a year can be attributed to antibiotic-resistant infections. Thus, understanding the different types of antimicrobial resistance is essential in order to combat this growing global health threat.

Below we’ll explore three types of antimicrobial resistance: natural resistance, acquired resistance and increased tolerance.

Types of Antimicrobial Resistance

Antimicrobial resistance means that microbes have become resistant to medicines—they’re no longer able to be treated with regular medications. This is a serious issue, as it can lead to infections that are difficult or impossible to treat.

There are several types of antimicrobial resistance. One of the most commonly known is antibiotic resistance, which occurs when bacteria no longer respond to antibiotics that were once effective at fighting them. Bacteria can also develop resistance to antiviral drugs, antifungal drugs and antiparasitic drugs.

Another type of antimicrobial resistance involves the transfer of genetic material between two cells, which then leads to a multidrug-resistant organism. This type of transfer can happen even between bacteria and humans, meaning that humans can become carriers for resistant organisms and pass it on through contact or food consumption.

Finally, biofilm-related resistances occur when microbes form protective layers around themselves so that standard treatments don’t penetrate them effectively.

By understanding the different types of antimicrobial resistances, you’ll be better equipped to take the necessary measures to prevent their spread.

Mechanisms of Antimicrobial Resistance

Antimicrobial resistance occurs when a microorganism evolves the ability to resist the effects of drugs. This means that an antibiotic may no longer be effective in treating an infection caused by a resistant bacteria or other microorganism.

So, what are the different mechanisms of antimicrobial resistance?

Change in Target Site: In this mechanism, the drug-target site is altered or modified so that it does not bind with the drug. For instance, some microbes acquire enzymes that alter penicillin so it cannot attach itself to its target site – the penicillin-binding protein in bacterial cell walls.

Alteration of Metabolic Pathways: This is another common form of antimicrobial resistance whereby metabolic pathways are altered to decrease the effectiveness of antibiotics. For example, organisms may develop enzymes that neutralize antibiotics or block their uptake into bacterial cells; enzymes like beta-lactamases can destroy penicillins like ampicillin and methicillin.

Reduced Uptake/Efflux Pump Action: Antimicrobials rely on being able to enter bacteria cells and actively kill them from within – however, some bacteria have developed ways to prevent uptake and/or pump out existing antimicrobials once they have entered the cell. This pumps action can render certain drugs ineffective at killing microbial cells.

How Antimicrobial Resistance Can Be Prevented and Managed

When it comes to antimicrobial resistance, prevention is key. Fortunately, there are several steps that you can take to reduce the spread of resistant bacteria in your workplace.

Properly Clean and Disinfect

Proper cleaning and disinfecting is one of the simplest and best ways to prevent the spread of resistant bacteria. Make sure all surfaces are thoroughly cleaned and disinfected, paying special attention to areas where food or bodily fluids may be present. You should also use appropriate personal protective equipment when cleaning these areas.

Properly Store Antimicrobials

Only use antimicrobials when absolutely necessary, and make sure they are properly stored away from direct sunlight or damp conditions. Be sure to follow recommended guidelines for disposal of unused or expired drugs as well.

Practice Good Hygiene

Good hygiene practices in the workplace are essential for preventing the spread of antimicrobial resistance. This includes covering any open wounds with a bandage, washing your hands frequently, and avoiding contact with others if you have a contagious illness. Encouraging proper handwashing techniques among your employees is also important for limiting the spread of resistant bacteria.

Share Knowledge

Make sure all employees in your workplace are aware of proper prevention and management protocols for antimicrobial resistance so they can make informed decisions about patient care. This includes making sure everyone has access to up-to-date information about antibiotics and other forms of treatment. Sharing this information will help ensure that everyone is on the same page when it comes to reducing the risk of resistant bacteria in your workplace.


All in all, it’s clear that antimicrobial resistance is a complex but crucial phenomenon to understand in the medical world. It’s not as simple as bacteria becoming resistant to antibiotics, and there are several different types of antimicrobial resistance that are all interconnected. Understanding the different types of antimicrobial resistance is a key step in finding solutions to this global health concern.

Taking a look at the big picture of antimicrobial resistance, it’s clear that the consequences can be dire, with the emergence of multidrug-resistant infections and an increased economic burden worldwide. Scientists, policymakers and the general public alike need to be aware of the importance of antimicrobial resistance in order to help mitigate its effects and prevent its spread.
