Each year, a brain tumor diseases claim the lives of more than 10 thousand Russians. For the most part, the causes of this oncological illness is unknown. It is possible that British scientists have found one explanation, but it does not just have to taste to millions of cat owners.
As we found out from the experts of the Research Institute of CNRS in Montpellier, France, the cause of development Brain Cancer a person may be entitled parasite Toxoplasma gondii That there are currently about a third of the inhabitants of the earth. In most cases, the parasite, living deep in the brain, to the end of life of a person is in an inactive state, without presenting any danger.
In Toxoplasma gondii a very complex life cycle in which it can eat really only inside cats. But these animals are subsequently transmitted to their owners microscopic eggs, spreading the infection. Pregnant women, in some countries, no longer recommended to empty and fill the cat litter, as the parasite can be fatal to an unborn child. But apparently now, scientists have transferred the risks and the wider community.
French scientists have gathered information from around the world relating to the cases Brain Cancer among men and women, and then comparing it with figures on infection Toxoplasma gondii. It was found that brain tumors are more common among the residents of those states in which has the highest infestation. This connection is maintained even when taking into account all other factors like the general welfare of the population.
By the way, scientists have proven link with the development of Toxoplasma gondii brain tumors animals. And some of these behavior changes after infection, indicating that infection of the brain. For example, rats are defying cats, causing them to eat quietly and kill rodents.
