Summary

Meningococcal disease, which typically presents as meningitis or meningococcemia, is a life-threatening illness requiring prompt antibiotic treatment for patients and antibiotic prophylaxis for their close contacts. Neisseria meningitidis isolates in the United States have been largely susceptible to the antibiotics recommended for treatment and prophylaxis. However, 11 meningococcal disease cases reported in the United States during 2019–2020 had isolates containing a blaROB-1 β-lactamase gene associated with penicillin resistance, as well as mutations associated with ciprofloxacin resistance. An additional 22 cases reported during 2013–2020 contained a blaROB-1 β-lactamasegene but did not have mutations associated with ciprofloxacin resistance.
