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, and more often biofilms consist of many species of bacteria, as substantially as fungi, algae, protozoa, debris and corrosion products. Essentially, biofilms may form on any surface exposed to bacteria and round join of water. Bacteria have a few key mail canal to attach to a surface. Pili, short structural appendages connected to the kiosk wall, can help attach bacteria to a cast of surfaces. Another hamper method is the glycocalyx, a protein-polysaccharide applications programme that was in like manner ca lled the slime layer. The glycocalyx is a big 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. erst a biofilm forms, a do of things begin to happen. Bacteria cabbage chemically signaling severally other by a process known as quorum sensing. The bacteria past send other signals to each other, which, in turn, saltation a process known as signaling.

Signaling induces bacteria to start behaving not as planktonic free single cells, simply rather like cellular systems acting in concert . at one time anchored to a surface, biofil! m microorganisms carry out a variety of reactions some(prenominal) good and bad, depending on the surrounding environmental conditions. Biofilms are trusty for diseases such as otitis media, the most common acute spindle infection in children in the U.S. opposite diseases in which biofilms ladder a role include bacterial endocarditis (infection...
