Invasive meningococcal disease (IMD) caused by Neisseria meningitidis is one of the most rapidly progressive sepsis syndromes, often resulting in significant morbidity and mortality. Since the introduction of meningococcal C conjugate vaccine in 2003, IMD in Victoria has decreased from 2.5/100 000 to 0.6/100 000 population.1 Epidemiological typing of N. meningitidis isolates is by serogroup, multilocus sequence typing and finetyping.
