Scientists discovered in the saliva of the parasite that is associated with the development of a range of serious diseases. Now there is every reason to believe that the organism Bdellovibrio causes the development of cystic fibrosis, periodontal disease and other diseases of the oral cavity. Other characteristics of the parasite tells the publication New Scientist.
Bdellovibrio lives entirely at the expense of the owner. Its habitat is the surface of the cells of other bacteria. This feature makes the microorganism is very secretive. Find it in the sample of saliva is sometimes not so easy. Most often, the parasite inhabits the bacteria Actinomyces odontolyticus.
Of special interest is the mechanism of interaction of the parasite and bacteria. His master Bdellovibrio kills gradually. In the process of life is a parasite sucking the essential amino acids, weakening the bacterium-host. As soon as the owner becomes extremely weak, the parasite replaces it with another house.
Note the species Actinomyces odontolyticus alone can cause gum disease. However, when the normal immunity of this bacterium survives in the human body. The parasite also gives the opportunity to adapt to the harsh and damage the mucosa.
