Understanding the role of bacteria in the body

Understanding the biology of Neisseria cinerea for the prevention of meningococcal disease

Research Exley Tang Oxford

Bacteria exist in complex communities on and in the human body. Many bacteria that use us as their home cause no harm; in fact, several are directly beneficial. A key function of our ‘good bacteria’ is that they can keep ‘bad’ bacteria at bay. However, how this happens, and what can be done to exploit this protective effect has received little attention.

The research

This project will examine how the harmless bacterium called N. cinerea, can influence disease caused by N. meningitidis, a bacterium responsible for bloodstream poisoning and meningitis. The research team will study how the harmless bacterium colonises cells at the back of the throat and whether it can either block the binding and invasion of N. meningitidis, or directly kill it. They have already discovered that N. cinerea has molecular weapons that are often used to destroy neighbouring bacteria. Finally they will investigate whether they can use N. cinerea to stimulate our immune system to destroy N. meningitidis.


This project will tell us how a bacterium like N. cinerea can successfully live in us, and how a greater understanding of this process can be used to protect us from serious infections such as meningococcal disease. 

This project started on 1 July 2016.
