British scientists have described a new species of bacteria that live in the tissues of the oral cavity of man. It is believed that the microorganisms, called Prevotella histicola, play a role in the development of caries and gum diseases. According to experts from King's College London, in the course of research they have discovered three previously unknown strain of bacteria of the genus Prevotella. Anaerobic gram-negative bacilli lived in healthy tissues of the mucous membranes of the mouth, and in the tissues of the cancer. New bacteria called Prevotella histicola (histicola - permanent inhabitant of tissue). "The oral health of people living a variety of microorganisms, including viruses, fungi, protozoa and bacteria," - said the head of research, William Wade (William Wade). - "Bacteria are the most numerous: in every milliliter of saliva contains about 100 million bacteria, which have not been described for more than 600 different species are more than half of them.." According to scientists, the new species play a role in the development play of tooth decay and gum disease. Understand further identification of microorganisms that live in the mouth, better, the mechanisms of these diseases, and will help scientists to develop new methods of prevention and treatment, said Wade. The study was published in the International Journal of Systematic and Evolutionary Biology.
