Impacts of Antibiotic Resistance 

Have you ever gotten a cut or scrap? Have you ever gotten a bacterial infection? Did it all turn out fine because you had antibiotics to treat it? What would you do if antibiotics were not so readily accessible? Well that could be a possibility soon as antibiotic resistance is on the rise and a serious threat to society today.

Bacteria obtaining antibiotic resistant can cause further implementation of very costly medication. This can become a problem for many uninsured or low-income populations. 

Antibiotic resistance also has an impact on research because scientist now have to implement a new method to target these newly antibiotic resistance bacteria.

Can the use of antibiotic in animals affect humans?
YES! The food that we consume can have genes that carry resistance and once we are in contact with it, it can attack our good bacteria and create mutations to other strains.

Always be careful of what you eat and check if you are eating uncooked meat
Prevention: Is there something that I can do to avoid this?
While antibiotic resistance is a naturally occurring phenomenon there are ways to help impede the process and stop the spreading of bacteria and antibiotic resistant bacteria.
For example, when prescribed antibiotics one can take the drugs as directed by a certified health professional. This means to take the medicine until the doctor says its okay to stop. The reason being is because people start feeling better, they stop taking the antibiotics which in turn leaves some bacteria alive which then can mutate and adapt to be resistant.
Another way to help is to only take antibiotics if it is prescribed. Also we need to stop the overuse and misuse of the drugs. Doctors now will try to avoid giving certain antibiotics until absolutely necessary as they do not want these drugs to become less effective.

Simple things like washing your hands regularly throughout the day and after using the bathroom, drinking clean water, and be sure that food is cooked thoroughly.
How does overuse of antibiotics cause resistance?

The frequent use of antibiotics when not necessary can cause the bacteria to adapt and evolve so that the antibiotics do not work against them. Due to the common and inappropriate use of antibiotics, certain bacteria that were once considered weak have become extremely resistant, even to the most powerful antibiotics available today. This is why it’s VITAL for health care professionals and patients to be mindful of the amount and frequency of antibiotics being prescribed/received. It is important to take antibiotics ONLY for bacterial infections. We can reduce the increasing strength of antibiotic resistance by allowing less severe illnesses, i.e. some that are caused by viruses, to just run its course. Losing the ability to treat serious bacterial infections is a major threat to public health.


Gram negative vs Gram positive

These are two different types of bacteria; gram negative and gram positive. Due to gram negative bacteria’s unique outer membrane, they are generally more resistance to antibiotics than gram positive bacteria. Their unique outer membrane excludes certain drugs and antibiotics from penetrating the cell. The pink stained bacteria is gram negative and the purple stained bacteria is gram positive.

A brief summary on how Antibiotic resistance may occur:

Why should we care? 

We should care about antibiotic resistance because it poses a threat to humans. For example, there are some bacterial infections that were once able to be treated in humans using a specific antibiotic, that are no longer able to be treated due to antibiotic resistance. This includes the methicillin-resistant Staphylococcus aureus (MRSA), that is also resistant to a lot of other antibiotics.
To further add: MRSA acquired its resistance from a non-native gene that encodes a penicillin-binding protein, significantly lowering its affinity for B-lactams. This resistance allows cell-wall biosynthesis, the target of B-lactams, to persist even in the presence of common antibiotics such as amoxicillin, methicillin, and penicillin.
Some ways in which we can bring antibiotic resistance to a minimum is not use antibiotics when unnecessary, like using antibiotics to treat the common cold, as antibiotics do not help against the common cold. Also, when prescribed an antibiotic to treat a bacterial infection, continue to take the antibiotics until they are gone instead of discontinuing them once asymptomatic.
Antibiotics are only able to treat bacterial infections; therefore, people should not use antibiotics to treat a common cold. There are some misconceptions that people have and it is important to spread this information to people to prevent antibiotic resistance.

According to the CDC, at least 30% of the antibiotics are prescribed in a misuse manner.
