False-negative PCR result due to gene polymorphism: the example of Neisseria meningitidis.

ABSTRACT: Early treatment of meningococcal meningitis is mandatory but may negate the cerebrospinal fluid culture. Etiological diagnosis then mainly relies on PCR. Here, we report a case of false-negative results for real-time PCR for a Neisseria meningitidis serogroup B isolate with a polymorphism in the ctrA gene.
