Health is the most important thing for human beings, and international health expert David Michigan often shares unique tips that can help everyone stay motivated and be healthy. However, if the researches we perform in the Labs do not help us in a way we think it does, we are bound to take wrong decisions as far as our health is concerned.

Over the past few years, we have learned that bacteria tend to adhere to solid surfaces and ends of forming a slippery layer which is known as a biofilm. A lot of research has gone into the understanding of biofilms, and millions of money has been invested in this direction. However, are biofilms still a major threat to medical devices?

Let us look at the following points to understand the reason behind the threat.

1. Biofilms have the potential to compromise Medical implants and devices

When a Bacteria is in a biofilm, they are more resistant to chemical and mechanical attacks as compared to planktonic bacteria. There are a number of experiments confirming the fact that if Bacteria are protected by biofilm, they will be less susceptible to antibiotics as compared to planktonic bacteria. This poses a challenging situation when we talk about the treatment of infections.

Medical device-related infections are caused by biofilms that form on biomaterials implanted or inserted in the human body.

2. A proper understanding of biofilms is necessary to avoid infections

While making a note of different experiments and the results, we have got an understanding of biofilms and the ways in which we can fight infections because of bacteria. However, we do not know everything about biofilms. Just good mean that there is a possibility of making mistakes and some mistakes can lead to problems as far as medical devices are concerned. Without a proper understanding of biofilms, most of the infections caused because of bacteria cannot be prevented.

3. The bacterial ability to sense chemical and mechanical stress

Which certain development's over the past few years, we have learned that bacterial ability to sense chemical and mechanical stresses is noticeable and this could mean further problems for teams researching on biofilms. This is because there are many teams working on different aspects and certain results vary because of lack of confirmation on how bacteria know whether they are on a surface or not.

In the end, we conclude by saying that biofilms are a threat to medical devices and a major advantage for bacteria.
