Study shows why some people may become seriously ill from meningococcal bacteria

Researchers at Karolinska Institutet in Sweden have come one step closer toward understanding why some people become seriously ill or die from a common bacterium that leaves most people unharmed. In a study published in The Lancet Microbe, the researchers linked RNA mutations within the bacterium Neisseria meningitidis to invasive meningococcal disease, marking the first time a non-coding RNA in a bacterium has been linked to disease progression.
