New approach to help prevent meningococcal outbreaks

Nasal drops of harmless bacteria can inhibit a related bug that sometimes causes meningococcal disease, according to new findings published online in Clinical Infectious Diseases. The study--conducted among college students, a group at higher risk for this often serious illness--suggests a new approach that could help suppress outbreaks of the disease, if supported by future research.

Meningococcal disease is caused by Neisseria meningitidis, which can infect the lining of the brain and the spinal cord, causing meningitis. Strains of the bacteria can also cause serious bloodstream infections. But N. meningitidis can also live silently in a person's nose and throat, without illness. These "colonized" carriers can spread the pathogen to others through close contact.

In the study, researchers placed drops containing low doses of Neisseria lactamica, a related but harmless bacterial strain, into the noses of 149 healthy university students in the United Kingdom. A control group of 161 students received drops of saline instead. Nose swabs were taken at regular intervals over six months and tested for both types of bacteria.#
