Streptococcus gordonii are a commonly occurring bacteria and they are a bacteria that causes different types of infection in humans, most commonly recognized as being the bacteria that causes problems in the mouth. Some of the infections people may get that involve Streptococcus gordonii include gingivitis, the disease of the gums that leads to heart disease, and tooth decay. The Streptococcus gordonii bacteria can colonize on the tooth enamel in the form of plaque and also serve as precursors toward developing tooth decay. Many people interested in this bacteria are primarily wondering how to get rid of it.
Streptococcus gordonii has been identified as type strain ATCC 10558 with type strain CNCTC 6731, type strain GMCC 1.2496, type strain DSM 6777, type strain NCTC 7865 and type strain CIP 105258 branching from it. These strains are orally occurring streptococcus gordonii. A Streptococcus gordonii has a genome size of roughly 2.2 Mbp, a G+C content of forty-two percent and it encodes two thousand and fifty one proteins. Streptococcus gordonii are one of the bacteria in the mouth that are capable of initiating a film for other bacteria to grow on. The bacteria that may follow the Streptococcus gordonii include Actinobacillus actinomycetemcomitans, Bacteroides forsythus (2) and P. gingivalis.
All streptococcus bacteria are gram positive, including Streptococcus gordonii bacteria. Gram positive bacteria accept agents such as antibiotics, detergents or dyes if administered. Streptococcus gordonii bacteria and all streptococcus bacteria are cocci or sphere shaped bacterium. The Streptococus gordonii bacteria have specialized survival characteristics to survive in the mouth as they do just as do all of the other streptococcus bacteria types.
The Streptococcus bacteria feed on carbohydrates in the mouth, fermenting them for energy. The beta glucoside substrates of sugar would include arbutin, esculin, salicin and cellobiose. It has been discovered more recently that colonization of hydroxyapatite by Streptococcus gordonii occurred on the hydroxyapatite when coated with saliva and produced an impairment in the heart valves of rabbits, something that may help find a solution for the problem when it occurs in humans.
The sugar sucrose is used by these bacteria to produce the sticky polysaccharide known as plaque. Other sugars are also digested in the mouth with these bacteria but instead of plaque they produce lactic acid. It is the lactic acid together with the plaque that makes the tooth enamel decay. The other sugars used by the bacteria to produce lactic acid include glucose, lactose and fructose. Scientists are currently exploring ways to create a vaccine for the prevention of tooth decay. Proteins that are part of the processes of the bacteria’s colonization on the teeth have been suggested to have the ability to produce antibodies that can perhaps inhibit the processes that lead to tooth decay.
