This‚ combined with the secretion of P. acnes in biofilm establishment on the follicular walls‚ results in the formation of microcomedone . Cells within these biofilms exhibit altered properties‚specifically pertaining to growth rate and gene transcription leading to enhanced TLR interactions .

to determine whether iodine used to control bacteria in dental unit wastewater could increase mercury concentrations in dental wastewater. Introduction: Two of the major concerns in dentistry are biofilm in dental unit waterlines and the contamination of dental unit wastewater with mercury. Biofilms are microscopic communities that consist of naturally occurring water bacteria and fungi which accumulate inside things like faucets‚ showerheads and in thin tubes used to deliver water in dental treatment

skin. Colonies of these bacteria can produce a protective slime called a hydrophobic biofilm. Staphylococcus epidermidis is usually not pathogenic unless it enters the human body. One of the most common places for infections are hospitals where people often have weakened immune systems‚ open wounds or medical devices implanted in their bodies. Staphylococcus epidermidis can be fatal because of the protective biofilm and the bacteria’s resistance to common antibiotics makes the infection difficult

Lyme disease is a bacterial infection‚ caused by bacterium Borrelia burgdorferi‚ that is transmitted through the bite of a tick. Bacterium borrelia burgdorferi is a spiral shaped bacteria (spirochetes) that causes lyme disease. This bacteria is carried by a variety of different kinds of ticks but the most common carrier is the blacklegged ticks or deer ticks. The tick doesn’t start out by carrying the disease‚ it receives it from another animal like a mouse‚ squirrel‚ or deer‚ and then it is passed

periodontal infections. As the bacteria infect the gum tissue‚ they release toxic substances that trigger the breakdown of gum and bone. Therefore dental biofilm which is also known as plaque plays a major role in the initiation and progression of periodontal disease. b. The second contributing factor is dental calculus‚ which is mineralized dental biofilm‚ which is a hard‚ tenacious mass that forms on the clinical crowns of the natural teeth and other dental prostheses. i.

response to an invader is to attack‚ which means that an indwelling urinary catheter is treated as a foreign body by the immune system. Within 6 hours of catheter placement‚ biofilm formation begins to adhere to the catheter providing a rich habitat for microorganisms to infect the host (Bjornson & Macera‚ 2009). Biofilm is responsible for approximately 65%-80% of infections and are up to 1000 times less receptive to antibiotics (Bjornson & Macera‚ 2009). The most frequent microbe to infect the
