Antibiotics and Bacterial Resistance
Antibiotics have changed how humanity fights bacterial diseases. They are also known as antibacterials and they help prevent and treat bacterial infections. Anyone who has taken antibiotics knows how the medicine works and how imperative it is to complete the entire course of an antibiotic. It is advised that even if you are feeling well, one should not stop taking the medicine. It increases the chances of antibiotic-resistant bacteria or relapse of the infection with even more force. Most of the leading health organizations and health authorities have been stating this and have even put it up on leading websites across the world to help people understand its importance.
Although there has been a lot of talk about how one should finish the course of the antibiotics, this has been a wrong advice been given out to people. One of the leading professors of Brighton and Sussex Medical School in the UK believes that this is a wrong advice been given to people. He also states that there is no scientific evidence which proves that discontinuation of an antibiotic can make them resistant to medicines.
It is also believed that finishing the drug course may actually be increasing the bacteria resistance across the globe. It was originally believed that the antibiotic kills the infection caused by bacteria and it may take up to a week or more to do it. So, the theory said that if you stopped the medicines midway you only kill the weak bacterias, however, the stronger ones stay behind and reproduce more quickly compared to earlier. Now, these strong bacterias also become resilient and pass on the genetics to the new bacterias make them resilient to the antibiotic. When you have the next onslaught of bacterial infection you end up with more tougher and stronger, antibiotic resilient bacterias.
This theory did make sense and it is known that the bacteria which do survive after antibacterial medicines tend to reproduce more quickly than others and carry traits of resistance to antibacterial medicines. Now, most experts tend to disagree with this theory. They believe that the theory is flawed and it is not true to certain extent. It is believed that the bacteria cannot create resistance that quickly. It rather takes time and has to be a large scale. The bacteria has to pass from host to host and gather all kinds of genetic traits. They may be resistant to a certain antibiotic even before they enter the host`s body. The large-scale use of antibiotics in both humans and animals has given the bacteria a chance to become resistant to the antibiotic.
It is not known to many doctors that a shorter course of antibiotics may be more effective than a longer one. If one is completing the course just for the sake of it and to decrease the risk of antibacterial resistance, they can be doing more harm than good. There is no scientific evidence for the same. Some doctors shared that length of the medicine does not define the effectivity and more study is required to be done to understand the effective courses of antibacterial medicines.
