However, occasionally some strains can also cause life-threatening diseases such as sepsis and bacterial meningitis. Comparative genomics demonstrates that only very subtle genetic differences between carriage and disease strains might be responsible for the observed virulence differences and that N. meningitidis is, evolutionarily, a very recent species. Comparative genome sequencing also revealed a panoply of genetic mechanisms underlying its enormous genomic flexibility which also might affect the virulence of particular strains. From these studies, N. meningitidis emerges as a paradigm for organisms that use genome variability as an adaptation to changing and thus challenging environments.
