Studies have shown that adding "friendly" bacteria to nasal drops can prevent meningitis

Together, they implanted a harmless bacteria gene into the nose, keeping it in the nose and triggering an immune response

The results of the study published in the journal Science Translational Medicine show that people have a strong immune response to the bacteria that cause meningitis

Meningitis occurs in all age groups, but mainly affects infants, young children, and the elderly

About 10% of adults carry Neisseria meningitidis in the back of the nose and throat without any signs or symptoms

The "friendly" bacterium N.

The new data builds on the team’s previous work and aims to take advantage of this natural phenomenon

For those people, Lactam N.

The research team gave it one of the key weapons of Neisseria meningitidis; a "sticky" surface protein that adheres to cells on the lining of the nose

These modified bacteria can not only induce a stronger immune response, but also survive longer

The results of this study, funded by the Medical Research Council, offer hope for this new method of preventing life-threatening infections without the need for drugs

Dr.

"Theoretically, it is possible to express any antigen in our bacteria, which means that we can adjust them to combat multiple infections that enter the human body through the upper respiratory tract

Professor Reid, the director of the Biomedical Research Center at the National Institutes of Health in Southampton, said: "This study shows that using nasal drops containing genetically modified bacteria can protect people from serious diseases
