Review on Bacterial Biofilms and its impact
Journal Title: International Journal of Advanced Microbiology and Health Research (IJAMHR) - Year 2018, Vol 2, Issue 3
Abstract
Bacterial biofilms are aggregation of bacteria, which are organized into structural communities and produce exopolysaccharide matrix as a major component for their stability. Basic structure of microbial colonies framed in extracellular polymeric substance and its development pass through multi step process which involves attachment, growth, maturation and expansion which are determined by certain factors. It is composed of bio molecules like deoxyribonucleic acid(DNA), protein, lipids and organic substances and communicate with each other through a process called quorum sensing. Bacterial biofilms have several impacts such as chronic bacterial infection (kidney stones, dental plaque and chronic inflammatory infections), contamination of food and water quality and antibiotic resistance. This leads to serious problems for living (humans and animals) and non living organisms like medical equipment and vents allow group of microscopic organisms to persist as reservoirs that can readily cause diseases by directly attacking the body tissues which spread to other patients. Several diagnostic techniques are employed in order to treatment, prevention and control of biofilm formation and its subsequent health effects. Different researches, reviews and awareness creation are needed to be undertaken on the bacterial biofilms and their impacts in developing countries, especially in Ethiopia.
