Biofilms: The Who, What, Where, Why, and How's

Antony Van Leeuwenhoek, the first microbiologist, initially saw bacteria in dental plaque, making him the first oral microbiologist and biofilm experimenter back in the 1600s. Biofilms solve when bacteria adhere to surfaces and begin to excrete a slimy, glue-like substance that croup anchor them to all kinds of material - much(prenominal) as metals, plastics, soil particles, medical implant materials, and tissue. A biofilm can be formed by a single bacterial species, just more often biofilms consist of many species of bacteria, as closely as fungi, algae, protozoa, debris and corrosion products. Essentially, biofilms may form on any surface exposed to bacteria and round issue forth of water. Bacteria have a few key transfer canal to attach to a surface. Pili, short structural appendages committed to the kiosk wall, can help attach bacteria to a cast of surfaces. Another fixing method is the glycocalyx, a protein-polysaccharide screening that was in like manner called the slime layer. The glycocalyx is a sluttish mass of carbohydrate-based material secreted by bacteria. This material is critical to the attachment of bacteria to surfaces and has a categorization of other functions as well. erstwhile a biofilm forms, a do of things begin to happen. Bacteria decease chemically signaling severally other by a process known as quorum sensing. The bacteria therefore send other signals to each other, which, in turn, dismount a process known as signaling.

Signaling induces bacteria to start behaving not as planktonic free single cells, nevertheless rather like cellular systems actin g in concert. once anchored to a surface, b! iofilm microorganisms carry out a variety of reactions both(prenominal) good and bad, depending on the surrounding environmental conditions. Biofilms are answerable for diseases such as otitis media, the most common acute pinna infection in children in the U.S. opposite diseases in which biofilms turn of events a role include bacterial endocarditis (infection...
