Biofilms

Bacteria in hiding: Why biofilms are so difficult to combat

1. Biofilm definition: what are biofilms and why are they a problem?

According to the biofilm definition, biofilms are layers of bacteria that can form on various surfaces. These layers are difficult to combat because they provide a kind of protective barrier for bacteria. Biofilms can occur on medical devices, implants or in pipelines and are a serious problem. They can lead to infections or even device failure. Another problem is that biofilm formation often occurs invisibly and can only be detected by special tests. Therefore, it is important to spread knowledge about biofilms and to take measures to prevent their formation or to combat them effectively.

2. How do biofilms form?

Biofilms are complex structures formed by bacteria and are difficult to combat. But how do they form? First, individual bacteria attach themselves to a surface and begin to multiply. In the process, they produce a matrix of polysaccharides and proteins in which they embed themselves. This matrix protects the bacteria from external influences such as antibiotics or the host organism's immune system. In addition, biofilms can also use various genetic mechanisms to develop resistance to drugs. Biofilm formation is thus a complex process that takes place at various levels and enables bacteria to successfully engage in the game of hide-and-seek.

3. Remove biofilm: that's why the bacteria are so difficult to fight.

Bacteria are particularly difficult to combat in biofilm because they are protected by the layer of mucus and other substances. This layer forms a kind of barrier that makes it difficult for antibacterial agents to penetrate to the bacteria. In addition, bacteria in biofilms can protect each other by activating certain genes that give them greater resistance to antibiotics. Furthermore, when biofilm is removed, the bacteria may be in different stages, meaning that some bacteria have already died and others are still alive. This further complicates bacterial control, as active ingredients may not be able to reach all bacteria. In summary, biofilms are a complex system of microorganisms that makes it difficult to combat them effectively.

4. Health effects

A biofilm is not only difficult to combat, but can also have a significant impact on health. This is because bacteria that are responsible for infections can settle and multiply in the mucus layers of the biofilm wound. Biofilms on teeth, for example, can lead to caries or, around implants, to inflammation and rejection. Biofilms can also cause dangerous pathogens to spread in medical devices such as catheters or ventilation tubes. It is therefore important to detect biofilms at an early stage and combat them in a targeted manner to minimize potential health risks.

5. Measures for combat

To combat biofilm formation, it is important to take targeted measures. One possibility is to clean and disinfect the surfaces regularly. Care should be taken to ensure that all areas are thoroughly treated and that no spots are overlooked. In addition, special cleaning agents can be used, which are designed to combat biofilms. Another option is the use of UV-C light or ozone to disinfect rooms and objects. A targeted increase in water temperature can also help to reduce biofilm formation. However, regular monitoring and inspection of the affected areas is also important to be able to react at an early stage and prevent biofilms from forming again.

6. Conclusion: the importance of combating biofilm bacteria for health

In summary, it can be said that the fight against biofilm bacteria is of great importance for health. This is because the formation of biofilms allows bacteria to protect themselves from the usual cleaning and disinfection measures and thus cause long-term damage to the body. It is therefore important to pay attention to regular and thorough cleaning in both private and public areas. The development of new technologies and methods to combat bacteria in biofilms should also be further pursued to avoid long-term health effects.

The solution against biofilm

PATHELEN® Hybrid is the first one-step solution for the efficient removal of biofilm.


PATHELEN® Hybrid is a wound therapy containing both hydrophilic and hydrophobic silica. The extra large surface structure of the silica (1 bottle of Pathelen Hybrid contains 2g with a surface area of approx. 600 m²) generates an extra high capillary action for the adsorption of biofilm, wound exudate, toxins and pathogenic germs. This ensures fast and efficient physical wound cleaning.

PATHELEN® Hybrid is a medical device class I registered with SWISSMEDIC and US FDA.
