Researchers from the United States and Italy discovered a substance that could offer protection against more than 300 strains of the bacteria Neisseria meningitidiso (Meningococcus B), which causes meningitis . A potentially lethal disease, which causes inflammation of the meninges, the membranes that line the brain and spinal cord.
The disease can produce brain damage , disability for learning, deafness, limb amputation and death in 5% of patients who suffer from it.
There are hundreds of strains of meningococcus and currently there are already vaccines against some of them, such as A, C, W-135 and Y. But meningococcus B, the most variant and most common, it has been very difficult to control; because of its high genetic diversity and you do not have a immunization.
The new substance was called G1 And, it is able to induce the antibodies to kill all the strains of meningococcus B. The compound, say scientists, could be used in a universal vaccine against hundreds of meningococcal variants.
