What is a bacterial biofilm?
Biofilms are one type of bacterial community. Instead of growth as individual cells that are not attached to each other, certain bacterial species may form biofilms and grow as one sheet covering the surface. Bacterial biofilm is held together through the sticky substance produced by the bacteria. This structure offers protection for bacteria from disinfectants or antibiotics, and therefore the main interest in medicine and industry is the main interest. Species, such as the species in klebsiella and pseudomonas bacteria families, are examples of species that can live together in bacterial biofilm. Surfaces that biofilms call home can be inanimate or even biological. For example, pseudomonas aeruginosa can live on the inner lung surfaces and potentially cause disease, or can live on surfaces such as the interior of the factory in the factory. Any surface that has good moisture and nutrient additions can support bacterial biofilm.
most often bacterialBiofilm contains more than one type of bacteria. It can also be home to other microbes such as mushrooms or algae. The clean surface can quickly be covered by organic molecules from the surrounding environment. The first bacteria that colonize the surface bar by attaching to the organic layer. The structure of biofilm, when developing, is held together by adhesive cloth made of sugars that produce bacteria themselves, which is difficult to release by cleaning.
bacterial toughness of biofilm allows bacteria to remain in areas where they would otherwise be removed by mechanical effect, liquid flow or biological effect. The surface of the teeth is one of the examples of the area where bacterial biofilms live, giving home to microbes that feed the nutrients present in the mouth. Flowers can move free bacteria down and out to the sea, but if the bacteria manages to find support on the rocks in the river, then it can sit there and thrive like the sameti biofilm.
Medical examples of biofilms include recurrent ears where bacteria causing diseases live inside the ear. Legionnair's disease, which is a potentially deadly pulmonary infection, arises from Legionella bacteria within the sources of hot water aerosol from their primary biofilms and embarking inside the lungs. Even medical devices that are necessary for some hospitalized patients, such as intravenous tubes or catheters, may have biofilms.
If biofilms were not advantageous for microbes, microbes would not create them. In addition to the ability to stay in an environment full of nutrients such as running river, bacterial biofilms are protective from antibiotics and disinfectants. More biofilm bacteria will survive the presence of a differently deadly -overshow than a free -floating bacterium. This characteristic of biofilm causes that bacteria that choose this way they live harder to kill in cases such as combat infections or maintain surfaces orcreep.
