A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

BACKGROUND: Meningococcal meningitis requires rapid diagnosis and immediate management which is enhanced by the use of PCR for the ascertainment of these infections. However, its use is still restricted to reference laboratories.

METHODS: We conducted an inter-laboratory study to assess the implementation and the performance of PCR in ten French hospital settings in 2010.

RESULTS: Our data are in favour of this implementation. Although good performance was obtained in identifying Neisseria meningitidis positive samples, the main issue was reported in identifying other species (Streptococcus pneumoniae and Haemophilus influenzae) which are also involved in bacterial meningitis cases.

CONCLUSIONS: Several recommendations are required and, mainly, PCR should target the major etiological agents (N. meningitidis, S. pneumonia, and H. influenzae) of acute bacterial meningitis. Moreover, PCR should predict the most frequent serogroups of Neisseria meningitidis according to local epidemiology.
