Neisseria meningitidis with decreased susceptibility to penicillin in Saskatchewan, Canada.
Moderately penicillin-resistant Neisseria meningitidis is rare in North America. We report an outbreak of meningococcal disease in Saskatoon, Saskatchewan, Canada, with serogroup C N. meningitidis. The MICs of penicillin ranged from 0.12 to 0.25 micrograms/ml, and all isolates showing decreased susceptibility had identical genomic fingerprints when they were compared by pulsed-field gel electrophoresis. Our data indicate that N. meningitidis that is moderately resistant to penicillin is prevalent in Saskatchewan, Canada.
